[Gimp-user] color pick up tool
hi all, one more question: the new color pick up tool (pipette) which is now available in the color selector reacts very strange. look at this: http://www.newhouse.at/messen.jpg I click on the pipette, click on the picture and get a very different foreground-color (look at the actual color - this is supposed to be the color in the picture, which is green) what's wrong with it? thanks tina -- newhouse - new media Bettina Karena Lechner neue str 16, 2565 neuhaus austria mobil: +43 660 46 25 0 25 tel.: +43 26 74 878 72 fax: +43 2674 878 81 mailto:[EMAIL PROTECTED] www.newhouse.at --- Der Anfang ist die Hälfte des Ganzen.

[Gimp-user] get raw histogram data for image, not just statistics
Hi, I would like to use the perl interface to automate processing of black and white images. I would like to set a threshold for white vs black on the images based upon the histogram without physically looking at each image. I dont want to do it using the gimp-gui. I would like to get an array consisting of the histogram hist[i] = count of pixels in image with intensity i. however the only function i see in the PDB is (mean,std_dev,median,pixels,count,percentile) = gimp_histogram (drawable,channel,start_range,end_range) which would require 256 calls of this function to get the data. Is there another function that can return an array of the histogram? My goal is to use the histogram to pick a threshold between gray background and text on a jpg image of a book page that I make a picture of with my digital camera. Thanks Mitchell I also posted this to usenet gimp group. I dont know how to avoid cross posting this. - Be a better Heartthrob. Get better relationship answers from someone who knows. Yahoo!

Re: [Gimp-user] Create layered animation from a tiled animation.
[EMAIL PROTECTED] wrote: Quoting Brian Vanderburg II [EMAIL PROTECTED]: Out of need I created a script and finally got it working even on 2.3.18. Normally an animation is either done as one layer for each frame or using GIMP Animation Package one file per frame. With the first method, it is not possible to have multiple layers per frame since a layer is a frame. With the second, multiple files must be kept. While GAP is good, for simple animations it would be easier to just store each frame in one image side by side. I would propose you consider modifying your script to handle the more generic case of multiple rows of tiles. Your dialog would need an additional entry for Tile Height and could provide a Use image height (ie, Single Row) checkbox for convenience. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user I've made those changes and more. It supports frame width (0 for image width), frame height (0 for image height) frame count (0 for rows * col) in case there are 3x3 rows but only say 7 frames, and direction (left to right then top to bottom or top to bottom then left to right). It may only work with gimp 2.3+ since it uses the function 'floor' and I don't know if gimp 2.2 has it.

[Gimp-user] 262K color palette for TFT
I want to optimize images for display on a cellphone with a 262K color (18bit) TFT screen. What's the easiest way to do this in gimp? Thanks! ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
Re: [Gimp-user] 262K color palette for TFT
I made a plugin to do this myself; it's fairly simple to script. This is what is involved in optimizing for 18bit: First, make a 64color palette; this will be a gray gradient from black to white, matching the intensities displayable on the TFT. The easiest way to do this is to reset FG/BG colors to default, and import the palette from the gradient 'FG to BG (RGB)' with 'number of colors' == 64. For each image: * Decompose the image (Colors-components-decompose, choose RGB) * Indexize the resulting image to your pre-made palette, with dithering (you may want to experiment with different dithering methods; I personally prefer 'positional'/'fixed' because it is predictable.) * Recompose the resulting image (Colors-components-recompose) * Close the 'work' image. The original image is now optimized for 18bit. You should be aware that the dithering will make the image harder to compress. If you just want a quick preview of the image using 18bit: * Colors-Posterize, select 64 levels of posterization. * If you don't want dithering, performing that step is all you need to throw away any data that is meaningless for 18bit display, so the image will compress better. Note: the above workflows are for 2.4rc2. If you are using a significantly earlier version of the GIMP, the decompose and recompose filters are instead found somewhere in a submenu of the 'Filters' menu.
