Description
Releases the image from memory.Please call this function when you are done with the image to free memory.
The plugin doesn't know whether you need the image later, so it can't free the memory for you.
You can use GMImage.ImageCount to find out how many images are open in memory.
Used to be named GMImage.Release before.
You need to release all image references returned by functions GMImage.New, GMImage.NewFromBase64, GMImage.NewFromContainer, GMImage.NewFromFile, GMImage.NewFromHex, GMImage.NewImagesFromContainer, GMImage.NewImagesFromFile, GMImage.Copy, GMImage.GetClipMask, MenuItem.GetImage, MenuItem.GetMixedStateImage, MenuItem.GetOffStateImage, MenuItem.GetOnStateImage, Twain.CurrentImage, and Barcode.Generate.
Examples
Show with and height
Let ( [
$Image = MBS("GMImage.NewFromContainer"; GraphicsMagick::image);
$Width = MBS("GMImage.GetWidth";$Image);
$Height = MBS("GMImage.GetHeight";$Image);
$Error = MBS("GMImage.Destroy";$Image)
];
$Width & " x " & $Height )
Create red square and save to container:
Set Variable [$img; Value:MBS( "GMImage.New"; "16x16"; "red" )]
Set Field [test::test; MBS( "GMImage.WriteToPNGContainer"; $img; "test.png" )]
Set Variable [$r; Value:MBS( "GMImage.Destroy"; $img)]
