ImageGear Samples

Your ImageGear Professional toolkit contains a comprehensive set of sample application programs, which are installed together with ImageGear shared object libraries and related files. Each sample is provided in source form. You can compile and execute each application to see the actual effects of the ImageGear function calls within it, or examine the source file to find examples of ImageGear API function calls and accompanying platform-specific calls. In addition, Accusoft permits you to use the sample applications’ source code. You can use the sample code as is, or cut and paste from it as you wish, to create, then expand, your own applications. The only restriction is that you may not distribute the original ImageGear sample applications with your applications.

The easiest ImageGear sample application is igconsole. It is a console-only application that does not require or use any UI. It lets you convert an image from one format to another.

All major operations that can be accomplished using ImageGear are demonstrated in the filters sample. It is a Motif-based GUI sample that lets you load and display images, apply basic image processing operations, and work with annotations. By running this application and then examining its source code, you can see how the calls to ImageGear functions such as IG_load_...(), IG_dspl_...() and IG_fltr_...() interact with the requirements and procedures of Linux programming. You can later use this program as a template for developing an application of your own.

The samples are located in the directory to which you have installed ImageGear (see the sections Directory Structure and Description of Installed Files).

You can begin developing an application easily by choosing an appropriate sample to start with as a template, making a backup copy to preserve it, and editing it - cutting and pasting whole sections from other samples, if you wish. In this way, you will begin with a working program that displays images on your screen from the start, so you can test and debug each new feature as you add it to your code.

See Description of Installed Samples for information about the available samples.
