Match and Identify Image Templates in C#

The code below categorizes a document in the following ways:

  • It creates two templates.

  • It identifies the template whose content most closely matches the content of the document.

  • It renames the document file using the name of the template.

  • It deletes the templates.

// C#
// We assume GdPicture has been correctly installed and unlocked.
using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
    // Create template A.
    int templateID = gdpictureImaging.ADRCreateTemplateFromFile(@"templateA.tif");
    gdpictureImaging.ADRSetTemplateTag(templateID, "TemplateA");

    // Create template B.
    templateID = gdpictureImaging.ADRCreateTemplateFromFile(@"templateB.tif");
    gdpictureImaging.ADRSetTemplateTag(templateID, "TemplateB");

    // Identify the template that has the best similar content and change the file name accordingly.
    templateID = gdpictureImaging.ADRGetCloserTemplateForFile("image.tif");
    string templateName = gdpictureImaging.ADRGetTemplateTag(templateID);
    File.Move("image.tif", templateName + "_image.tif");

    // Deletes all document identifier templates.
    int templateCount = gdpictureImaging.ADRGetTemplateCount();
    for (int i = 1; i <= templateCount; i++)
        templateID = gdpictureImaging.ADRGetTemplateID(1);
