PrintPreview DSPDF save to file in Gray Scale issue

Postby VPC16 » October 18th, 2018, 6:57 pm

Using DSPDF for output does not seem to save to file in Gray Scale when the PrintPreview is in Gray Scale. The General Demos also do not save in Gray Scale. Not obvious if this could be coded in.
Thanks again for the great components in Delphi Area.

This behavior is intentional.

In the grayscale mode, the component converts visible pages into bitmaps, then converts the bitmaps into grayscale, and finally renders the bitmaps on screen. If we save these raster images as a PDF, we lose some quality and portability that PDF offers.

After all, you can always print a PDF in grayscale, right?
