Method
VipsImagewrite_prepare
Declaration [src]
int
vips_image_write_prepare (
VipsImage* image
)
Description [src]
Call this after setting header fields (width, height, and so on) to allocate resources ready for writing.
Normally this function is called for you by vips_image_generate() or
vips_image_write_line(). You will need to call it yourself if you plan to
write directly to the ->data member of a memory image.
