Method
VipsImagecopy_memory
Declaration [src]
VipsImage*
vips_image_copy_memory (
VipsImage* image
)
Description [src]
This function allocates memory, renders image into it, builds a new
image around the memory area, and returns that.
If the image is already a simple area of memory, it just refs image and
returns it.
Call this before using the draw operations to make sure you have a memory image that can be modified.
vips_copy() adds a null “copy” node to a pipeline. Use that
instead if you want to change metadata and not pixels.
This operation is thread-safe, unlike vips_image_wio_input().
If you are sure that image is not shared with another thread (perhaps you
have made it yourself), use vips_image_wio_input() instead.
