The class handles GD images. Usage: $source = GdImage::fromFile($objFile); $target = GdImage::fromDimensions(100, 100); $source->copyTo($target, 0, 0, 100, 100); $target->convertToPaletteImage() ->saveToFile('image.jpg');
Deprecation: Deprecated since Contao 4.3, to be removed in Contao 5.0. Use the Imagine library instead.
