See the Representation Guide for simple image representation samples.
This is a command line application that displays information obtained from a file using the IM I/O functions, basically imFile functions. It depends only on the IM main library.
Here is an output sample:
IM Info File Name: exif_test.tif File Size: 9.00 Mb Format: TIFF - Tagged Image File Format Compression: NONE Image Count: 1 Image #0 Width: 2048 Height: 1536 Color Space: RGB Has Alpha: No Is Packed: Yes Is Top Down: Yes Data Type: byte Data Size: 9.00 Mb Attributes: YResolution: 72.00 XResolution: 72.00 DateTime: 2004:01:14 11:30:11 Make: SONY ResolutionUnit: DPI Model: CD MAVICA Photometric: 2

This application uses IUP and CD to create a window with a canvas and draw the image into that canvas. It is a very simple application, no zoom nor scrollbar management. The image is obtained from a file using the IM I/O functions, but using the imImage structure to make the implementation easier.
