ReleaseImage

Image handling

Version history

This function was introduced in Quick PDF Library version 8.15.

Description

Releases the temporary memory used by an image that was added to the PDF after the document was opened (using functions such as AddImageFromFile) or an image that was found using the FindImages function.

Releasing the image does not affect the PDF itself, images that have already been drawn onto the page will not be removed.

After the image has been released the ImageID is no longer valid and cannot be used with functions such as SelectImage.
