Expand description
Crop away unwanted pixels. Includes automatic detection of bounding rectangle. Currently does not support deep data and resolution levels.
Structs
A smaller window into an existing pixel storage
A writer for the cropped view layer
Enums
Cropping an image fails if the image is fully transparent.
Use [or_crop_to_1x1_if_empty] or [or_none_if_empty] to obtain a normal image again.
Traits
Realize a cropped view of the original data,
by actually removing the unwanted original pixels,
reducing the memory consumption.
Currently not supported for SpecificChannels.
Crop some pixels ways when specifying a smaller rectangle
Crop away unwanted pixels from the border if they match the specified rule.
Something that has a two-dimensional rectangular shape
Inspect the pixels in this image to determine where to crop some away
Functions
Return the smallest bounding rectangle including all pixels that satisfy the predicate.
Worst case: Fully transparent image, visits each pixel once.
Best case: Fully opaque image, visits two pixels.
Returns None if the image is fully transparent.
Returns [(0,0), size] if the image is fully opaque.
Designed to be cache-friendly linear search. Optimized for row-major image vectors.
