I'm totally inexperienced with GIMP but I chanced upon this recipe that would meet my needs for a rather big project I'm currently doing. It's about cleaning scanned magazine pages where the print on the back side shines through the thin paper making the reading less enjoyable.
Recipe: With GIMP: Open a file. Convert your document to grayscale: Image - Mode - Grayscale. Select the background color: Select - By Color, click with mouse pointer on the color of the background. Invert the selected color: Select - Invert. Copy the selection: Edit - Copy. Create a new file: File - New. In the dialog of a new file, in field: Advanced Options choose: Fill with: White, hit Ok. Click anywhere in the window of the new opened document, just to choose it. Paste the content of a clipboard: Edit - Paste. Add a new layer to enhance the black text: Layer - New from Visible, in the layer's palette, in field: Mode: choose Multiply. Combine two layers: Layer - Merge Down. Save the result as a JPEG file: File - Export As, choose jpeg and set the quality at least 60. I have a couple of questions. A. When getting to "Combine two layers: Layer - Merge Down." the Merge Down option is grayed out so I can't apply that step. What could be the reason? And why does it say "Combine two layers" when there is three? 1.Floated selection (Pasted Layer) 2.Visible 3.Background B. When selecting a background color to be erased/turned to white what would be the best way to pick a wider range of grayness than the rather sparse instruction the recipe suggests "By Color, click with mouse pointer on the color of the background." -- MrNiceButDim (via www.gimpusers.com/forums) _______________________________________________ gimp-user-list mailing list List address: gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
