Forced to convert color after scanning with TWAIN
If I scan a gray-scale picture (8 bit) with TWAIN and then tell XnView to save it, a menu opens to convert the color mode of the picture - by default into 24 bit color. For me this convertion menu should not be standard because it is unnecessary. It gets on my nerves after every scan. The color mode I select with TWAIN should be the color mode I want to save the picture. If not one can convert it manually.

So perhaps normal, jpeg can only save grey or truecolors picture, and your TWAIN driver return perhaps a colormap picture...Anonymous wrote:Sorry, I didn't mention it. The Format was JPEG.xnview wrote:Which format do you use?

No, I don't think so, because after the picture is imported from TWAIN the statusbar of XnView showes 256 colors. That means that XnView knows that this is a grey picture. Besides that the convert color window opens automatically only if grey pictures were imported and not if color pictures were imported.xnview wrote:So perhaps normal, jpeg can only save grey or truecolors picture, and your TWAIN driver return perhaps a colormap picture...

No 256 colors means 256 colors with colormapjens116 wrote:No, I don't think so, because after the picture is imported from TWAIN the statusbar of XnView showes 256 colors.
