PdfEnableColorDetection Property (GdPictureDocumentConverter)

In This Topic
Enables or disables the automatic color detection feature when converting/saving the currently loaded document to PDF format.

The purpose is to automatically detect the original color of documents scanned in color mode and convert the B/W and/or grayscale ones to the appropriate bpp (bits-per-pixel) encoding. The result is allowing preservation of image quality while considerably reducing the file size.
