Re: [Gimp-user] creating a line art channel or layer in GIMP
Dave M G wrote: GIMP Users, I'm a long time and proficient PhotoShop user trying to learn how to work in GIMP. My goal is to colour comic book style images using GIMP. I'm okay with not having CMYK support, as my images are most likely to appear on the web. What I do is scan inked images with Xsane as line art. Then what I want to do is create a layer that is pure black, and use the scanned image as an alpha channel for that layer. That way I can add colours underneath the layer, without affecting the line art. However, I'm stuck as to exactly how to create that alpha channel. I can create an alpha channel for a layer, but I can neither paste the line art image into that alpha channel, nor can I seem to invert the image so the right parts are transparent and the right parts are opaque. Can anyone provide instructions or direct me to a tutorial for this sort of thing? I will gladly RTFM if someone can show me where in the FM to R. Also, I have other concerns on the horizon which pertain to colouring inked comic images using GIMP. Things like ensuring there is no anti-aliasing when I use any of the tools. There are lots of tutorials of this nature for PhotoShop, but I was unable to find any that had GIMP specific instructions. If anyone knows of good directions for comic art using GIMP, that would help a lot. I look forward to any advice, and hope to hear from you soon. Thank you. -- Dave M G ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user Not sure if this might help. How about - (1) Start by creating a transparent base layer - File= New= Advanced Options= Fill With= Transparency (2) Make a new layer to carry your line art - Layer Dialog= New Layer= Layer Fill Type= White (if you want a white background to the lines) or Background (if you want a black background to the lines: N.B. on the main GIMP panel, check the panel in the bottom Left corner, where there are two large oblongs, one in front of the other, and two tiny ones, ditto. If the large oblong behind (i.e.background) is white, click on the double-headed bent arrow at its upper right-hand corner; this will switch the colours of the large oblongs (foreground and background), making the background black). (3) get or copy your line art onto this new layer. It will have to be white on the black background or black on the white background. (If you use, say the Gimp pencil tool, which always draws in foreground colour, you may need to swop foreground and background colours by clicking the bent double-headed arrow by the large oblongs in order to get the right colour for drawing). (4) Right click on the image= Select= By Colour. Carefully position the mouse arrow over a line somewhere and left click. This will select your line drawings. Ctrl-X (or Right click= Edit= Cut) to cut the colour of the layer under the lines and make them transparent to the layer below. (5) What colour do you want your lines to show at? Go back to the main GIMP panel and the large oblongs. Double click in one or the other (foreground or background). This brings up a panel, Change Foreground (or Background) Colour. When you've selected the desired colour and clicked OK, the appropriate oblong on the main GIMP panel should now take on that colour. Go back to the Layers Dialog. New Layer= Layer Fill Dialog. Choose Background colour or Foreground colour (depending which you've coloured). You then have a coloured layer. (6) Move the coloured layer down. Layer Dialog= Down arrow. Your line art should appear coloured on your white (or black) ground in the colour of the coloured layer. I hope that's relevant.

[Gimp-user] matting or anti-aliasing of shapes
Hi all, I try to anti-alias or matte the edges of a shape in order to make a transparent gif/png of it without having pixelated 'hard edges'. The current situation is that I have a selection of some shape in GIMP. Below the layer with the shape in it, I stroke the selection of my shape with a lighter colour by using a fuzzy paintbrush. This gives me some sort of anti-alising effect, but it isn't any close to the matte option in the 'export for web' dialog of Photoshop. Because I really do like GIMP, I am curious if there is a better way to get anti-aliased shapes using Gimp?
