[Gimp-user] Change black to dark something in image, when printer is out of black ?
Hi, The scenario - have an inkjet printer which regularly runs out of black ink, but still has plenty of colour ink. I would like to change black to dark blue or whatever, so I can print eg. a concert ticket with a black barcode, which will still scan fine at the venue entrance. On SGI in Days of Olde, this would be repcol ticket.rgb 0 0 0 0 0 20 10 or similar, ie. replace all pixels within 10 units (out of 255) of black with dark blue. Good old Paul Haeberli and his gfx tools. Appreciate assistance in doing this in Gimp - 2.6.7 on Mac with Snow Leopard (10.6). Or indeed a command line tool of any kind, I need this little trick quite a bit. ATdhvaannkcse !

Re: [Gimp-user] saving layers
Suppose there are three different layers in a stack that need to be saved individually and then used as the input for a RPI plugin. What would be the best procedure to use, please? Make the layer you wish to save active by clicking on its thumbnail preview in the Layers Dialog, then from the File Menu select the Save As item. Give your filename a .png extension. Since the PNG format does not support multi-layer images, you will be presented with an Export Dialog which asks whether you want to Flatten your image or Merge its layers; you want to do neither so click on the Ignore button and just the active layer will be saved. Repeat the process for the other layers. Thank you for that way of dealing with the problem. I have found another way which is to drag the thumbnail up to the tool box when a new window opens and the image can be saved from there as '.xcf' or even worked on before saving.

Many printer drivers can do this. A dark blue would still consist of a lot of black since GIMP only knows about RGB and only when printing this is converted to a more printer-native representation.

Here is a plug-in to export all layers as PNG files: http://registry.gimp.org/node/18440 I wrote it as an exercise in learning more about python and GIMP, so it's not battle-tested. May kick your dog, eat your kittens, etc. Only tested on linux, but it *should* work on win/mac. Although if you are only dealing with three layers, it probably won't help much - I was thinking of having 10 or 20 layers and having to save each one...
