SECTION 4. IMAGE SPECIFIC COMMANDS
This section describes the commands available for the transmission, storage and management of images.
Some important characteristics of the images generated by MICRImage are:
• The default image resolution used is 200 dpi.
• Images are compressed according to ITU T.6, also referred to as CCITT Group 4.
• The images are stored using the TIFF file format.
• The TIFF format contains a number of descriptive fields of data (“tags”) each tagged with a number
(up to 65534). Many of these tags are predefined and contain items such as image length, height, and
compression method.
• The TIFF format also allows the inclusion of an unlimited amount of private or special-purpose
information utilizing a number of user defined tags. MICRImage provides commands that allow
programming of these TIFF tags.
The following TIFF tags are included in every image file. Tag # 270 can be modified using MICRImage
commands.
