[Gimp-user] help changing a color
I have read and looked at tutiorals and I just cant get it to work. All I am trying to do is change the color of a gif and png. They are for a website and I just need to change the color of the objects. That is all. Any help in very simple terms would help -- tamss13 (via gimpusers.com) ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
Re: [Gimp-user] Layer masks: how do you memorize which color means opaque?

In particular, which memory aids exist to remember when to use black and when to use white. I think of it like illumination. Cool. I think of it as a window or transparent overlay. If I imagine the mask as a window above the layer, then white is clear and anything darker than that is masked from view.

I assume you are talking about menu buttons or simple graphic borders. 1. Change the mode! to RGB. Most tools do not work on indexed colour formats such as gif/png. IMAGE MODE RGB 2. Open the Hue/Saturation dialogue: COLOURS HUE-SATURATION 3. Drag the Huw slider to left or right then click OK 4. Save the image. (The GIMP will prompt with a couple of dialogues before the colours are indexed again and saved.)

Any help in very simple terms would help Simple method if you have very clean colors borders (no antialiasing): 1) Set the foreground color to your final color 2) Start the color selection tool (betwen the magic wand and the scissors in the tools palette). Set the treshold to 0. Click any part of the icon that is with the old color. This will select all the parts of the image that have the very same colors 3) Start the bucket-fill tool (bucket icon). select FG color fill, and Fill whole selection. Click somewhere in the selected areas. 4) Done. More complex method that also covers anti-aliased border: 1) Menu: Colors/Color to alpha... Click on the color bar, and in the next dialog use the color picker on a spot of the color you want to change. This should replace the old color with a checkboard pattern (this indicates the image has become transparent at these places) 2) Set the background color to your final color 3) Open the layers dialog (Ctrl-L or Windows/Dockable dialogs/Layers) 4) Add a new layer (right click and Add new layer), or use the icon with the + at the bottom. In the dialog, use a fill t original oneype of Background color 5) In the layer dialog, drag this dialog under the original one. You'll see this layer through the holes punched at step 1) in the original layer, in effect replacing the color. 6) You can then save the picture directly as GIF/PNG/JPG (Gimp will flatten it automaticaly). Note that if at this point you also save the picture as XCF you can produce other versions with different colors by just replacing the color of the bottom layer. Since I have often seen this question asked to match the color of some background over which the picture appears, and even better solution in this case is to save the picture right after step 1) in a format that support transparency (PNG or GIF). -- Ofnuts ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] Help with image alterations
Hello List - I recently downloaded the GIMP2.6 and have been playing with it in an attempt to modify some existing pictures and generally play with the outcome. Kind of like Mr. Potato Head (hopefully you know what that is) , I am trying to take a part of one picture, say the nose, and transpose it to another picture; or perhaps the lips, eyes, etc. Once I have one aspect copied on the other picture I get stuck making it happen, both in context and melding of image sizes and a “seamless” transition. Could you refer me to the right tutorial, or provide me a facile method to perform this feature using GIMP? Also, how do you rectify the image size so that if the pictures are of different sizes the transposed part looks of appropriate dimension to the host picture. I very much appreciate your time and any input you might afford me. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

I know about the lag of Linux but there's a lot of source code available that you can compile yourself.Double fun. I am purely an amateur so speed in producing results is no concern. Your post has made me doubt what would be best. The cheapest Intuos (which I think has tilt) comes at € 220 (6x4 ins). You might check places like ebay. Every day people buy tablets and then end up never using them and selling them practically new for a great price. The new Intuos at 6.3 x 3.9 active area sells for $229 US. It has +-60 degrees of tilt. 5080 lines per inch (as do all of the Intuos of any size). 2048 pressure sensitivity levels. It's pretty good! On Amazon, a used one is as low as $149 right now, and a used medium is as low as $249. If you'd be happy with the Intuos 3, ebay has a bunch of new ones really cheap. Wouldn't it be cool to have a big cintiq? $1999 US. There's plans on the web to make your own from recycled parts. http://www.bongofish.co.uk/wacom/wacom_pt1.html or http://www.maximumpc.com/article/features/maximum_pc_builds_a_multitouch_surface_computer Patrick ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

I very much appreciate your time and any input you might afford me. The right way to do it is to keep all the added bits in their own layer until the end. Layers can be moved, scaled and rotated around with the move, scale and rotate tools in the tools palette. You can combine move and scale quite seamlessly (but if anyone knows how to rotate at the same time, I'll be glad to hear it). Seamless transition between layers is achieved by gradual transparency on the edges. The easy way to achieve it is to feather the selection on a couple of pixels when you copy/paste. A more complete way is to use layer masks that give you full control of the amount of transparency of all pixels in a layer. Basicall you add a mask to the layer in the layers dialog and click on it to make the editable thing. Wherever you apply black the layer image is transparent and where it's white the layer is opaque. You can of course use various levels of grey... so you can literally paint transparency. -- Ofnuts ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
Re: [Gimp-user] Circular Graphics

I have a very nice rectangular jpg graphic that I want to change into a circle to be used for a circular sticker application.

Any help you can give me would be appreciated. Maureen If you want to cut a circle out of the middle of it: 1. make sure there is alpha in the image so we can save a square image that looks like a circle 2. make a circular selection with the ellipse selection tool (hold shift to ensure a circle) 3. invert the selection, (press ctrl+i) this selects everything but the circle so we can delete it 4. delete (just press the delete key) 5. invert the selction (ctrl+i again), this selects the circle again 6. crop to selection (Image-Crop to Selection) 7. canvas size to selection (Image-Fit Canvas to Selection) 7b. optionally now, depending on your application, you can feather the selection to make a more gradual edge. You can play with the number of pixels and use ctrl+z to undo in between. 8. Save it/Export it with a new name.
