affine_trans_image_size — 2D `geometry` op

• Data kinds: image → image

• Call: fullseye.apply(img, "affine_trans_image_size", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

• HALCON equivalent: affine_trans_image_size (the HALCON reference is a useful guide to its meaning and parameters)

affine_trans_image_size: 入力 → 出力

*The figure is the real output on a synthetic 128×128 input. Left: input, right: output (a non-image return value is shown as the value itself).*

Usage

Applies an affine transform (rotation + shear) to the image. The implementation shares the `affine branch of _sh_geom with affine_trans_image`; a sets the rotation angle to -20 to +20 degrees, and b sets the shear amount. Out-of-bounds areas are filled by reflection (reflect).

HALCON の `affine_trans_image_size（アフィン変換を適用し、出力画像のキャンバスサイズを明示的に指定できる演算）とは異なり、この実装は出力サイズの指定を受け付けず、常に入力と同じキャンバスサイズを保つ近似（affine_trans_image` と実質同一の実装）。
