Sample Programs

LEADTOOLS supports your programming endeavors with thousands of code snippets, function examples, tutorials, and demo programs.

Demo Programs

Demo programs showcase LEADTOOLS core features, and demonstrate some of the simple, yet powerful applications that can be produced with LEADTOOLS.

Demo Executables

LEADTOOLS demo executables show and allow you to manipulate basic toolkit functionality through a simple user interface. Demo executables are found on the installation path in the appropriate platform subdirectory of the \BIN\ folder (for example: C:\Program Files\LEAD Technologies\LEADTOOLS EVAL 16\Bin\CDLL\Win32).

Demo Project Source Code

LEADTOOLS includes complete demo project source code for hundreds of LEADTOOLS features, (including those shown in demo executables). This enables you to see, manipulate, and copy demonstrated program functionality. Demo project source code is found on the installation path in the appropriate platform subdirectory of the \EXAMPLES\ folder (for example, C:\Program Files\LEAD Technologies\LEADTOOLS EVAL 16\Examples\CDLL).

Specific demo project source code references for each LEADTOOLS component and platform are listed in the Getting Started tables, under the topical headings belowlocated in Getting Started with Leadtoolslocated in the LEADTOOLS Imaging SDK Getting Started help file.

Demo Tutorials

For many demo executables, LEADTOOLS also includes tutorials that walk through the demo features and provide guidelines and code snippets for programming variants and options. Demo tutorials are found in the relevant help file, listed in the Contents tab under "Features of...— Using...Demos."

For example, the Barcode Demos are documented in Barcode WebHelp-Demosthe Barcode Module help file.

Tutorial (Model) Programs

Tutorial programs are straightforward, stepwise models that show useful solutions to practical problems. You can use these as a starting point, cut and paste code, or simply review them for highlights on how to write code for a specific feature or problem. Tutorial (model) programs are found in the relevant help file, listed in the Contents tab under "Features of...— Tutorials."

For example, a Barcode tutorial is documented in Barcode WebHelp-Tutorialthe Barcode Module help file.

Examples and Code Snippets

The documentation for each LEADTOOLS function reference includes an Example at the bottom of each page, with additional code snippets as needed in the Comments section. Where appropriate, these are related back to the relevant Demo and Tutorial programs.

For example, the Barcode function LBarCode::Read, including code snippets, an example, and reference to additional demo project source code, is documented in Barcode WebHelp-Examplethe Barcode Module help file.
