Enumeration
VipsExtend
Description [src]
See vips_embed(), vips_conv(), vips_affine() and so on.
When the edges of an image are extended, you can specify how you want the extension done.
VIPS_EXTEND_BLACK --- new pixels are black, ie. all bits are zero.
VIPS_EXTEND_COPY --- each new pixel takes the value of the nearest edge
pixel
VIPS_EXTEND_REPEAT --- the image is tiled to fill the new area
VIPS_EXTEND_MIRROR --- the image is reflected and tiled to reduce hash
edges
VIPS_EXTEND_WHITE --- new pixels are white, ie. all bits are set
VIPS_EXTEND_BACKGROUND --- colour set from the background property
We have to specify the exact value of each enum member since we have to keep these frozen for back compat with vips7.
