Syntax
sod_img sod_make_empty_image(int w, int h, int c);Description
Fill a sod_img object with the desired dimension and set the raw pixels data pointer to NULL unlike sod_make_image(). A NULL data pointer is usually used as a marker to identify empty images where a call to one of the processing interfaces is a no-op.
Parameters
int w
Image width.
int h
Image height.
int c
Total number of desired color channels (i.e 1 for grayscale image, 3 for standard BGR/RGB/YuV/HSV image).
Return Value
Filled sod_img except the raw pixels data pointer member of this structure is set to NULL.
