image() public method

The upper-left corner and at least one of the dimensions must be specified; the height or the width can be calculated automatically in order to keep the image proportions. Supported formats are JPEG and PNG. All coordinates can be negative to provide values from the right or bottom edge of the page (since File_Pdf 0.2.0, Horde 3.2). For JPEG, all flavors are allowed: - gray scales - true colors (24 bits) - CMYK (32 bits) For PNG, are allowed: - gray scales on at most 8 bits (256 levels) - indexed colors - true colors (24 bits) but are not supported: - Interlacing - Alpha channel If a transparent color is defined, it will be taken into account (but will be only interpreted by Acrobat 4 and above). The format can be specified explicitly or inferred from the file extension. It is possible to put a link on the image. Remark: if an image is used several times, only one copy will be embedded in the file.
