Method
VipsImageshrinkh
Declaration [src]
int
vips_shrinkh (
VipsImage* in,
VipsImage** out,
int hshrink,
...
)
Description [src]
Optional arguments:
ceil: round-up output dimensions
Shrink in horizontally by an integer factor. Each pixel in the output is
the average of the corresponding line of hshrink pixels in the input.
This is a very low-level operation: see vips_resize() for a more
convenient way to resize images.
This operation does not change xres or yres. The image resolution needs to be updated by the application.
See also: vips_shrinkv(), vips_shrink(), vips_resize(), vips_affine().
