Description

A few simple typedefs used by VIPS.

Functions

VipsCallbackFn ()

int
(*VipsCallbackFn) (void *a,
                   void *b);

VipsSListMap2Fn ()

void *
(*VipsSListMap2Fn) (void *item,
                    void *a,
                    void *b);

VipsSListMap4Fn ()

void *
(*VipsSListMap4Fn) (void *item,
                    void *a,
                    void *b,
                    void *c,
                    void *d);

VipsSListFold2Fn ()

void *
(*VipsSListFold2Fn) (void *item,
                     void *a,
                     void *b,
                     void *c);

Types and Values

VipsPel

typedef unsigned char VipsPel;

A picture element. Cast this to whatever the associated VipsBandFormat says to get the value.

enum VipsPrecision

How accurate an operation should be.
