class MyImage(MyBlob, Image): (source)

View In Hierarchy

ZMS image blob class for managing image files with metadata.

MyImage extends MyBlob with image-specific functionality including:

Image Features:

  • Width and height metadata tracking
  • Automatic dimension detection from SVG and raster images
  • Image resizing and thumbnail generation
  • Configurable default dimensions (width, height)

Data Management:

  • Inherits blob storage from MyBlob (ZODB or MediaDB)
  • XML serialization with width/height attributes
  • Content-type handling (image/png, image/jpeg, image/svg+xml, etc.)

Uses OFS.Image.Image as the underlying Zope file storage mechanism.

Method getHeight Get height of this image.
Method getWidth Get width of this image.
Method toXml Serialize this file to xml-string.

Method _getCopy Get copy of this blob.

Inherited from MyBlob:

Method __bobo_traverse__ Return the blob itself during traversal.
Method __call__ Handle HTTP request for blob object (file/image).
Method __str__ Undocumented
Method equals Indicate whether another blob is equal to this one.
Method get_real_size Returns real size in ZODB.
Method getContentType Returns MIME-type (e.g. image/gif, text/xml).
Method getData Returns data.
Method getDataSizeStr Returns display string for file-size (kB). Deprecated: Use standard.getDataSizeStr(len) instead!
Method getDataURI Return the blob payload as a data URI.
Method getFilename Returns filename.
Method getHref Return the absolute URL for this blob.
Method getMediadbfile Returns mediadb-filename.
Method getMimeTypeIconSrc Returns the absolute-url of an icon representing the MIME-type of this MyBlob-object. Deprecated: Use zmscontext.getMimeTypeIconSrc(mt) instead!
Method getObjAttrs Return object attribute definitions for this blob.
Method on_setobjattr Persist blob data to MediaDB and detach acquisition wrappers when needed.
