The fire effect will be contain within width = 10 and 200\n low_ & high_ values must be in range [0 ... width_] \n \n * FIRE HEIGHT:\n \n input factor_ : float\n \n The fire maximum height can be adjust with the variable factor_ (float value)\n value > 3.95 will contain the effect within the display \n value < 3.95 will enlarge the effect over the display height \n Recommended value is 3.95 with reduce_factor_ = 3 otherwise adjust the value manually \n to contain the fire effect within the display\n \n * SPEED CONSIDERATION\n \n input reduce_factor_ : integer\n \n The argument reduce_factor_ control the size of the texture to be processed \n e.g : a value of 2, divide by 4 the pygame surface define by the values (width_ & height_)\n Smaller texture improve the overall performances but will slightly degrade the fire aspect, \n especially if the blur and smooth option are not enabled.\n Recommended value for reduce_factor_ is 3 (fast process) \n reduce_factor_ values must be an integer in range [ 0 ... 4] \n The reduce_factor_ value will have a significant impact on the fire effect maximum height, \n adjust the argument factor_ accordingly\n\n * FIRE INTENSITY AT THE SOURCE\n \n input fire_intensity_: integer\n \n Set the fire intensity with the variable fire_intensity_, 0 low flame,\n 32 maximum flame effect\n Values must be an ""int in range [0 ... 32] \n\n * SMOOTHING THE EFFECT\n \n input smooth_: True | False\n \n When smooth_ is True the algorithm will use the pygame function smoothscale (bi-linear \n filtering) or False the final texture will be adjust with the scale function.\n Set this variable to False if you need the best performance for the effect or if you require\n a pixelated fire effect. Otherwise set the variable to True for a more realistic effect. \n\n \n * BLOOM EFFECT \n \n input bloom_ : True | False\n input fast_bloom_ : True | False\n input bpf_threshold_ : integer\n \n Fire effect produce a bright and smooth light effect to the background texture where the fire \n intensity is at its maximum.\n Use the flag fast_bloom_ for a compromise between a realistic effect and the best performances\n The flag fast_bloom_ define a very fast bloom algo using only the smallest texture \n to create a bloom effect (all the intermediate textures will be bypassed). See the bloom effect \n project for more details.\n When fast_bloom is False, all the sub-surfaces will be blit to the final effect and will \n produce a more realistic fire effect (this will slightly degrade the overall performances). \n If the fire effect is too bright, you can always adjust the bright pass filter value\n bpf_threshold_(this will adjust the bloom intensity)\n bpf_threshold_ value must be in range [ 0 ... 255] \n Below 128 the bloom effect will be more noticeable and above 128 only the brightest\n area will be enhanced.\n\n * LIGHT EFFECT INTENSITY\n\n input brightness_ : True | False\n input brightness_intensity_ : float\n\n When the flag is set to True, the algorithm will use an external function, \n <shader_brightness24_exclude_inplace_c> to increase the brightness of the effect / texture\n A custom color can be passed to the function defining the pixels to be ignored during t""he \n process (default is black color).\n the value must be in range [-1.0 ... 1.0]. Values below zero will decrease the brightness \n of the flame effect and positive values will increase the brightness of the effect (causing\n bright white patches on the fire texture). \n Values below -0.4 will cause the fire effect to be translucent and this effect can also be \n used for simulating ascending heat convection effects on a background texture.\n \n \n * OPTIONAL SURFACE\n \n input surface_ : pygame.Surface\n \n This is an optional surface that can be passed to the shader to improve the performances \n and to avoid a new surface to be generated every iterations. The surface size must match \n exactly the reduce texture dimensions otherwise an exception will be raise. \n see reduce_factor_ option to determine the fire texture size that will be processed.\n \n * COLOR PALETTE ADJUSTMENT \n \n input adjust_palette_ : True | False\n input hsl_ : (10, 80, 1.8)\n\n Set this flag to True to modify the color palette of the fire texture. \n This allow the HSL color model to be apply to the palette values\n You can redefine the palette when the flag is True and by customizing a tuple of 3 float \n values, default is (10, 80, 1.8). \n The first value control the palette hue value, the second is for the saturation and last, \n the palette color lightness. \n With the variable hsl_ you can rotate the palette colors and define a new flame\n aspect/color/intensity\n If adjust_palette_ is True the original palette define by the argument palette_, will \n be disregarded.Instead a new palette will be created with the hsl values\n\n * FLAME ORIENTATION / DIRECTION & BORDER FLAME EFFECT\n \n input transpose_ = True | False,\n input border_ = True | False,\n \n transpose_ = True, this will transpose the final array \n for e.g : \n If the final fire tex""ture is (w, h) after setting the transpose flag, the final \n fire texture will become (h, w). As a result the fire effect will be transversal (starting \n from the right of the display to the left side). \n You can always transpose / flip the texture to get the right flame orientation \n BORDER FLAME EFFECT \n border_ = True to create a flame effect burning the edge of the display. This version is only\n compatible with symmetrical display or textures (same width & height). If the display \n is asymmetric, the final border fire effect will be shown within the display and not neccessary \n on the frame border \n \n * FINAL TOUCH\n \n input blur_ : True | False\n \n This will will blur the fire effect for a more realistic appearance, remove all the jagged \n edge when and pixelated effect\n \n \n :param width_ : integer; Size (width) of the surface or display in pixels\n :param height_ : integer; size (height) of the surface or display in pixels\n :param factor_ : float; Value controlling the fire height value\n must be in range [3.95 ... 4.2].\n The value 3.95 gives the highest flame effect\n :param palette_ : numpy.ndarray, buffer containing mapped RGB colors (uint values)\n :param fire_ : numpy.ndarray shape (w, h) containing float values (fire intensity).\n For better performance it is advised to set the array to the size \n of the texture after applying the reduction_factor_.\n For example if the reduction_factor_ is 2, the texture would have \n width >> 1 and height >> 1 and the fire_array should be set to \n numpy.empty((height >> 1, width >> 1), float32)\n :param reduce_factor_ : unsigned short int ; Can be either 0, 1, 2, 3, 4. \n "" 2 and 3 provide the best performance and the best looking effect.\n :param fire_intensity_ : Integer; Control the original amount of energy at the\n bottom of the fire, must be in range of [0 ... 32]. \n 32 being the maximum value and the maximum fire intensity\n :param smooth_ : boolean; True smoothscale (bi-linear filtering) or\n scale algorithm jagged edges (mush faster)\n :param bloom_ : boolean; True or False, True apply a bloom effect to the fire effect\n :param fast_bloom_ : boolean; Fastest bloom. This reduce the amount of calculation\n :param bpf_threshold_ : integer; control the bright pass filter threshold\n value, must be in range [0 ... 255].\n Maximum brightness amplification with threshold = 0, \n when bpf_threshold_ = 255, no change.\n :param low_ : integer; Starting position x for the fire effect\n :param high_ : integer; Ending position x for the fire effect\n :param brightness_ : boolean; True apply a bright filter shader to the array.\n Increase overall brightness of the effect\n :param brightness_intensity_: float; must be in range [-1.0 ... 1.0] control\n the brightness intensity\n of the effect\n :param surface_ : pygame.Surface. Pass a surface to the shader for\n better performance, otherwise a new surface will be created each \n calls.\n :param adjust_palette_ : boolean; True adjust the palette setting HSL\n (hue, saturation, luminescence).\n Be aware that if adjust_palette is True, the optional palette \n passed to the Shader wil""l be disregarded\n :param hsl_ : tuple; float values of hue, saturation and luminescence.\n Hue in range [0.0 ... 100], saturation [0...100], \n luminescence [0.0 ... 2.0]\n :param transpose_ : boolean; Transpose the array (w, h) become (h, w).\n The fire effect will start from the left and move to the right\n :param border_ : boolean; Flame effect affect the border of the texture\n :param blur_ : boolean; Blur the fire effect\n :return : Return a pygame surface that can be blit directly to the game display\n\n ";

01951: inputs low_ : integer
01952: input high_ : integer
01953:
01954: Optional arguments low_ & high_ (integer values) define the width 's limits of the fire effect.
01955: low_ for the starting point and high_ for the ending of the effect.
01956: e.g low_ = 10 and high_ = 200. The fire effect will be contain within width = 10 and 200
01957: low_ & high_ values must be in range [0 ... width_]
01958:
01959: * FIRE HEIGHT:
01960:
01961: input factor_ : float
01962:
01963: The fire maximum height can be adjust with the variable factor_ (float value)
01964: value > 3.95 will contain the effect within the display
01965: value < 3.95 will enlarge the effect over the display height
01966: Recommended value is 3.95 with reduce_factor_ = 3 otherwise adjust the value manually
01967: to contain the fire effect within the display
01968:
01969: * SPEED CONSIDERATION
01970:
01971: input reduce_factor_ : integer
01972:
01973: The argument reduce_factor_ control the size of the texture to be processed
01974: e.g : a value of 2, divide by 4 the pygame surface define by the values (width_ & height_)
01975: Smaller texture improve the overall performances but will slightly degrade the fire aspect,
01976: especially if the blur and smooth option are not enabled.
01977: Recommended value for reduce_factor_ is 3 (fast process)
01978: reduce_factor_ values must be an integer in range [ 0 ... 4]
01979: The reduce_factor_ value will have a significant impact on the fire effect maximum height,

01991:
01992: input smooth_: True | False
01993:
01994: When smooth_ is True the algorithm will use the pygame function smoothscale (bi-linear
01995: filtering) or False the final texture will be adjust with the scale function.
01996: Set this variable to False if you need the best performance for the effect or if you require
01997: a pixelated fire effect. Otherwise set the variable to True for a more realistic effect.

02005:
02006: Fire effect produce a bright and smooth light effect to the background texture where the fire
02007: intensity is at its maximum.
02008: Use the flag fast_bloom_ for a compromise between a realistic effect and the best performances
02009: The flag fast_bloom_ define a very fast bloom algo using only the smallest texture
02010: to create a bloom effect (all the intermediate textures will be bypassed). See the bloom effect
02011: project for more details.
02012: When fast_bloom is False, all the sub-surfaces will be blit to the final effect and will
02013: produce a more realistic fire effect (this will slightly degrade the overall performances).
02014: If the fire effect is too bright, you can always adjust the bright pass filter value
02015: bpf_threshold_(this will adjust the bloom intensity)
02016: bpf_threshold_ value must be in range [ 0 ... 255]

02024:
02025: When the flag is set to True, the algorithm will use an external function,
02026: <shader_brightness24_exclude_inplace_c> to increase the brightness of the effect / texture
02027: A custom color can be passed to the function defining the pixels to be ignored during the
02028: process (default is black color).
02029: the value must be in range [-1.0 ... 1.0]. Values below zero will decrease the brightness
02030: of the flame effect and positive values will increase the brightness of the effect (causing
02031: bright white patches on the fire texture).
02032: Values below -0.4 will cause the fire effect to be translucent and this effect can also be
02033: used for simulating ascending heat convection effects on a background texture.
02034:
02035:
02036: * OPTIONAL SURFACE
02037:
02038: input surface_ : pygame.Surface
02039:
02040: This is an optional surface that can be passed to the shader to improve the performances
02041: and to avoid a new surface to be generated every iterations. The surface size must match
02042: exactly the reduce texture dimensions otherwise an exception will be raise.
02043: see reduce_factor_ option to determine the fire texture size that will be processed.
02044:
02045: * COLOR PALETTE ADJUSTMENT
02046:
02047: input adjust_palette_ : True | False
02048: input hsl_ : (10, 80, 1.8)
02049:
02050: Set this flag to True to modify the color palette of the fire texture.
02051: This allow the HSL color model to be apply to the palette values
02052: You can redefine the palette when the flag is True and by customizing a tuple of 3 float
02053: values, default is (10, 80, 1.8).
02054: The first value control the palette hue value, the second is for the saturation and last,
02055: the palette color lightness.
02056: With the variable hsl_ you can rotate the palette colors and define a new flame
02057: aspect/color/intensity
02058: If adjust_palette_ is True the original palette define by the argument palette_, will
02059: be disregarded.Instead a new palette will be created with the hsl values
02060:
02061: * FLAME ORIENTATION / DIRECTION & BORDER FLAME EFFECT
02062:
02063: input transpose_ = True | False,
02064: input border_ = True | False,
02065:
02066: transpose_ = True, this will transpose the final array
02067: for e.g :
02068: If the final fire texture is (w, h) after setting the transpose flag, the final
02069: fire texture will become (h, w). As a result the fire effect will be transversal (starting
02070: from the right of the display to the left side).
02071: You can always transpose / flip the texture to get the right flame orientation
02072: BORDER FLAME EFFECT
02073: border_ = True to create a flame effect burning the edge of the display. This version is only
02074: compatible with symmetrical display or textures (same width & height). If the display
02075: is asymmetric, the final border fire effect will be shown within the display and not neccessary
02076: on the frame border
02077:
02078: * FINAL TOUCH
02079:
02080: input blur_ : True | False

See the bloom effect \n project for more details.\n When fast_bloom is False, all the sub-surfaces will be blit to the final effect and will \n produce a more realistic cloud effect (this will slightly degrade the overall performances). \n If the cloud effect is too bright, you can always adjust the bright pass filter value\n bpf_threshold_(this will adjust the bloom intensity)\n bpf_threshold_ value must be in range [ 0 ... 255] \n Below 128 the bloom effect will be more noticeable and above 128 only the brightest\n area will be enhanced.\n\n * LIGHT EFFECT INTENSITY\n\n input brightness_ : True | False\n input brightness_intensity_ : float\n\n When the flag is set to True, the algorithm will use an external function, \n <shader_brightness24_exclude_inplace_c> to increase the brightness of the effect / texture\n A custom color can be passed to the function ""defining the pixels to be ignored during the \n process (default is black color).\n the value must be in range [-1.0 ... 1.0].

02272: process (default is black color).
02273: the value must be in range [-1.0 ... 1.0]. Values below zero will decrease the brightness
02274: of the cloud effect and positive values will increase the brightness of the effect (causing

02336: bloom effect will use the smallest texture)
02337: :param bpf_threshold_ : integer; Bright pass filter value must be in range [ 0 ... 255]
02338: 0 produce the maximum bloom effect

05861: BLOOM EFFECT (SIMPLIFY VERSION)
05862:
05863: This version is compatible with moving object in the display.
05864:
05865: The other bloom versions cause the halo of light to be offset from moving
05866: objects due to the re-scaling (down sampling) of the sub-surfaces and the loss
05867: of accuracy.
05868:
05869: The quantity of bloom can be adjust with the bright pass filter threshold
05870: (variable threshold_). The variable can help you to choose what level of
05871: light can trigger a bloom effect.
05872: The lowest the value the brightest the effect.
05873:
05874: The smooth factor will help to spread the light homogeneously around the objects.
05875: A large number of smooth will cast the bloom over the entire scene and diminished
05876: the overall bloom effect, while a small value will pixelate the hallo around objects
05877: but will generate the brightest effect on objects.
05878: When smooth is below 3, the halo appear to be slightly pixelated.
05879:
05880: You can use the saturation to generate saturated colors within the light
05881: effect.
05882: The flag can be used to create different special effect with the light within the
05883: pygame display. The default value is pygame.BLEND_RGB_ADD and allow to blend
05884: the bloom to the display.
05885: Nevertheless you cann also use any of the other flags such as BLEND_RGB_MAX, BLEND_RGB_SUB etc

07679:
07680: * FIRE TEXTURE SIZES
07681:
07682: input width_ : integer,
07683: input height_ : integer
07684:
07685: width_ and height_ values define the size of the texture e.g Surface(width x height)
07686:
07687: * FIRE ASPECT (CONTROL OVER THE WIDTH):
07688:
07689: inputs low_ : integer
07690: input high_ : integer
07691:
07692: Optional arguments low_ & high_ (integer values) define the width 's limits of the fire effect.
07693: low_ for the starting point and high_ for the ending of the effect.
07694: e.g low_ = 10 and high_ = 200. The fire effect will be contain within width = 10 and 200
07695: low_ & high_ values must be in range [0 ... width_]
07696:
07697: * FIRE HEIGHT:
07698:
07699: input factor_ : float
07700:
07701: The fire maximum height can be adjust with the variable factor_ (float value)
07702: value > 3.95 will contain the effect within the display
07703: value < 3.95 will enlarge the effect over the display height
07704: Recommended value is 3.95 with reduce_factor_ = 3 otherwise adjust the value manually
07705: to contain the fire effect within the display
07706:
07707: * SPEED CONSIDERATION
07708:
07709: input reduce_factor_ : integer
07710:
07711: The argument reduce_factor_ control the size of the texture to be processed
07712: e.g : a value of 2, divide by 4 the pygame surface define by the values (width_ & height_)
07713: Smaller texture improve the overall performances but will slightly degrade the fire aspect,
07714: especially if the blur and smooth option are not enabled.
07715: Recommended value for reduce_factor_ is 3 (fast process)
07716: reduce_factor_ values must be an integer in range [ 0 ... 4]
07717: The reduce_factor_ value will have a significant impact on the fire effect maximum height,
07718: adjust the argument factor_ accordingly
07719:
07720: * FIRE INTENSITY AT THE SOURCE
07721:
07722: input fire_intensity_: integer
07723:
07724: Set the fire intensity with the variable fire_intensity_, 0 low flame,
07725: 32 maximum flame effect
07726: Values must be an int in range [0 ... 32]
07727:
07728: * SMOOTHING THE EFFECT
07729:
07730: input smooth_: True | False
07731:
07732: When smooth_ is True the algorithm will use the pygame function smoothscale (bi-linear
07733: filtering) or False the final texture will be adjust with the scale function.
07734: Set this variable to False if you need the best performance for the effect or if you require
07735: a pixelated fire effect. Otherwise set the variable to True for a more realistic effect.
07736:
07737:
07738: * BLOOM EFFECT
07739:
07740: input bloom_ : True | False
07741: input fast_bloom_ : True | False
07742: input bpf_threshold_ : integer
07743:
07744: Fire effect produce a bright and smooth light effect to the background texture where the fire
07745: intensity is at its maximum.
07746: Use the flag fast_bloom_ for a compromise between a realistic effect and the best performances
07747: The flag fast_bloom_ define a very fast bloom algo using only the smallest texture
07748: to create a bloom effect (all the intermediate textures will be bypassed). See the bloom effect
07749: project for more details.
07750: When fast_bloom is False, all the sub-surfaces will be blit to the final effect and will
07751: produce a more realistic fire effect (this will slightly degrade the overall performances).
07752: If the fire effect is too bright, you can always adjust the bright pass filter value
07753: bpf_threshold_(this will adjust the bloom intensity)
07754: bpf_threshold_ value must be in range [ 0 ... 255]
07755: Below 128 the bloom effect will be more noticeable and above 128 only the brightest
07756: area will be enhanced.
07757:
07758: * LIGHT EFFECT INTENSITY
07759:
07760: input brightness_ : True | False
07761: input brightness_intensity_ : float
07762:
07763: When the flag is set to True, the algorithm will use an external function,
07764: <shader_brightness24_exclude_inplace_c> to increase the brightness of the effect / texture
07765: A custom color can be passed to the function defining the pixels to be ignored during the
07766: process (default is black color).
07767: the value must be in range [-1.0 ... 1.0]. Values below zero will decrease the brightness
07768: of the flame effect and positive values will increase the brightness of the effect (causing
07769: bright white patches on the fire texture).
07770: Values below -0.4 will cause the fire effect to be translucent and this effect can also be
07771: used for simulating ascending heat convection effects on a background texture.
07772:
07773:
07774: * OPTIONAL SURFACE
07775:
07776: input surface_ : pygame.Surface
07777:
07778: This is an optional surface that can be passed to the shader to improve the performances
07779: and to avoid a new surface to be generated every iterations. The surface size must match
07780: exactly the reduce texture dimensions otherwise an exception will be raise.
07781: see reduce_factor_ option to determine the fire texture size that will be processed.
07782:
07783: * COLOR PALETTE ADJUSTMENT
07784:
07785: input adjust_palette_ : True | False
07786: input hsl_ : (10, 80, 1.8)
07787:
07788: Set this flag to True to modify the color palette of the fire texture.
07789: This allow the HSL color model to be apply to the palette values
07790: You can redefine the palette when the flag is True and by customizing a tuple of 3 float
07791: values, default is (10, 80, 1.8).
07792: The first value control the palette hue value, the second is for the saturation and last,
07793: the palette color lightness.
07794: With the variable hsl_ you can rotate the palette colors and define a new flame
07795: aspect/color/intensity
07796:
07797: * FLAME ORIENTATION / DIRECTION & BORDER FLAME EFFECT
07798:
07799: input transpose_ = True | False,
07800: input border_ = True | False,
07801:
07802: transpose_ = True, this will transpose the final array
07803: for e.g :
07804: If the final fire texture is (w, h) after setting the transpose flag, the final
07805: fire texture will become (h, w). As a result the fire effect will be transversal (starting
07806: from the right of the display to the left side).
07807: You can always transpose / flip the texture to get the right flame orientation
07808: BORDER FLAME EFFECT
07809: border_ = True to create a flame effect burning the edge of the display
07810:
07811: * FINAL TOUCH
07812:
07813: input blur_ : True | False
07814:
07815: This will will blur the fire effect for a more realistic appearance, remove all the jagged
07816: edge when and pixelated effect
07817:
07818:
07819: :param width_ : integer; Size (width) of the surface or display in pixels
07820: :param height_ : integer; size (height) of the surface or display in pixels

07824: :param palette_ : numpy.ndarray, buffer containing mapped RGB colors (uint values)
07825: :param fire_ : numpy.ndarray shape (w, h) containing float values (fire intensity).
07826: For better performance it is advised to set the array to the size
07827: of the texture after applying the reduction_factor_.
07828: For example if the reduction_factor_ is 2, the texture would have
07829: width >> 1 and height >> 1 and the fire_array should be set to
07830: numpy.empty((height >> 1, width >> 1), float32)
07831: :param reduce_factor_ : unsigned short int ; Can be either 0, 1, 2, 3, 4.
07832: 2 and 3 provide the best performance and the best looking effect.
07833: :param fire_intensity_ : Integer; Control the original amount of energy at the
07834: bottom of the fire, must be in range of [0 ... 32].
07835: 32 being the maximum value and the maximum fire intensity
07836: :param smooth_ : boolean; True smoothscale (bi-linear filtering) or
07837: scale algorithm jagged edges (mush faster)
