Image AutoCrop using VC++

This example shows how to crop an image automatically. (It also shows how to invoke other functions that can prepare an image for OCR processing.)
[src]
void CImgEdit1Dlg::OnCleanup()
{
// Here are some functions you might want to perform on
// an image prior to OCR.

VARIANT evt; V_VT(&evt) = VT_ERROR; // set to default
// Perform automatic straighten on the image
ImgEdit1.AutoDeskew();
// Remove speckles on the image using the default
// threshold value for dot size
ImgEdit1.Despeckle(evt);
// If there is a lot of extraneous space around image
// borders, cropping might reduce processing time
ImgEdit1.AutoCrop(evt);
// Show the OCR dialog box
ImgOcr1.ShowOcr();
}
