    What I meant to say is that one can't rely on a JFIF marker or text string to detect the start of a JPEG file, as it is optional and could occur later in the data or not at all. The IV optimization...

    Maybe add a configurable limit to the number of Undo steps and/or an option to purge Undo history to the Edit menu (where Clear Clipboard is) to release the memory.

    The basic color reduction method is indeed bad, it adds 240 for white. "Best color quality" is very slow, but selected 255,255,254 and 3,2,3, which are very close to white/black. The new "best"...

    You can load/export a palette (Image>Palette) in Jasc Paint Shop Pro human-readable format in IrfanView, but that function is not available in batch mode. Maybe you can request Irfan over e-mail for...

    Next time try to scan at maximum color depth, but less dpi, and don't use levels/tone enhancement in the scanning software. You can always reduce the bit depth later, after applying a contrast...

    I guess you first need to determine what is your printer's resolution somewhere in its setup dialog, where you can configure its speed/economy. Did you try setting the image DPI to match the...

    Experiment with curves. But maybe you can scan a more accurate image in the first place, and proceed from there. In the scanning software you want to defeat automatic color/histogram adjustments. It...
