TTiffImage is a TFPImageBitmap descendant which implements support for the TIFF (Tag Image File Format) image format.
It is a raster graphics image format. TIFF is widely supported by scanning, faxing, word processing, optical character recognition, image manipulation, desktop publishing, and page-layout applications. TIFF was created for use as a common image format for scanners. Various revisions to the specification have added grayscale and color support to the image format. It is a popular format for deep-color images.
TIFF images use .TIF or .TIFF file extensions, and the MIME types 'image/TIF' or 'image/TIFF'.
TTiffImage implements the class methods from the ancestor class which get FCL TFPCustomImageReaderClass and TFPCustomImageWriterClass instances, as well as the shared graphics class instance for the image format.
TTiffImage has properties which expose values for Baseline Tags in the image data, including:
