Function Macro
VipsMATRIX
Declaration [src]
#define VIPS_MATRIX (
I,
X,
Y
)
Description [src]
This macro returns a pointer to a pixel in an image, cast to a double*. The
image must have a single band, be VipsBandFormat and be
fully available in memory, so memory buffers and small
mapped images only.
If VIPS_DEBUG is defined, you get a version that checks bounds and image
type for you.
