Chicken bindings for the imlib2 image library.
imlib:alpha-set! wasn't exportedNote: Not all imlib functionality is provided by this egg yet!
imlib:image object which describes a transparent image of the given size.img object is an imlib image.imgimlib:image object which describes the image stored in the file filename. This automatically uses the correct loader, as determined by Imlib2 on the basis of the file's extension.img in the file filename. The right loader is automatically selected by Imlib2 if you haven't set it explicitly with imlib:format-set!.#f if no format has been associated with it yet.imlib:save. The format argument is passed to the loaders in the same way a file extension would be.#f.img. By default, all images are cached by imlib2 in such a way that closing and reopening it just pulls it from cache instead of really loading it. Unfortunately, there's no way to request the status of this option or disable it.img.img horizontally.img.img vertically.img. This works like transposing a matrix.img diagonally.img. According to imlib2 documentation, this function rotates the image by 90 degrees orientation times. However, the function accepts values between 0 and 7, inclusive. What values 4-7 do, I'm not really sure of. They appear to rotate the image (mod orientation 3) times 90 degrees, but flip it as well.img. The radius argument is an integer number indicating the degree of sharpening that has to take place. I am not sure what a negative value means, but it is allowed.img. The radius argument is a positive integer indicating the blur matrix radius, so 0 has no effect.img adjusted in such a way around the edges, such that it is suitable for use in repeating ("tiled") patterns on all sides.img adjusted on the left and right edges so it can be used for horizontally repeating patterns.img adjusted on the top and bottom edges so it can be used for vertically repeating patterns.img. The x and y parameters indicate the upper left pixel of the new image. The width and height parameters indicate the size of the new image. Returns #f on failure. Note: This function will return an image of the requested size, but with undefined contents if you pass it arguments that lie outside the image! I am still unsure if this is a bug or feature.img. The arguments src-x, src-y, src-width and src-height indicate cropping dimensions as per imlib:crop, in the original image. The dest-width and dest-height arguments indicate the new image's width and height.Note: This could use some more work. Perhaps the functions fromthe previous section should return values of these types instead.
