ImageGear for C and C++ on Windows v19.5 - Updated
Samples
User Guide > Getting Started > Samples

Your ImageGear for C and C++ on Windows toolkit contains a comprehensive set of sample application programs, which are installed together with ImageGear DLLs and related files. Each sample is provided in both executable and source form. You can 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.

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.

The ImageGear for C and C++ samples are listed in the table below. The table delineates where you can find the samples within the Samples directory (C:\Users\Public\Documents\Accusoft\ImageGear for C and C++ v19\Samples\SourceCode\), and where you can access the Sample applications from the Start menu (Programs>Accusoft>ImageGear for C and C++ v19>Samples).

The samples are located in the directory to which you have installed ImageGear (see the "Description of Installed Files" section in the Installation topic).
