Thumbnail and Watermark
This is a class that can process an image on the fly by either generate a thumbnail and/or apply an watermark to the image. The processed image can either be displayed in a page, saved to a file, or returned to a variable. It requires the PHP with support for GD library extension in either version 1 or 2. If the GD library version 2 is available it the class can manipulate the images in true color, thus providing better quality of the results of resized images. Features description: - Thumbnail: normal thumbnail generation - Watermark: Text or image in PNG format. Suport multiples positions. - Auto-fitting: adjust the dimensions so that the resized image aspect is not distorted - Scaling: enlarge and shrink the image - Format: both JPEG and PNG are supported, but the watermark image can only be in PNG format as it needs to be transparent - Autodetect the GD library version supported by PHP - Calculate quality factor for a specific file size in JPEG format.
