Re: [Gimp-user] Extracting all pixels of a certain colour
I want to extract all pixels of a specific colour (to be more precise look a certain colour). I am finding that there is some variation in the colour. so if I try select by color. I only get a subset of the pixels. Is there a way of selecting all pixels close to the colour I want (where close can be determined by experimentation!) Select by color allows to set a threshold - if you set it to 0, only the exact color is selected, the higher you set it the less similar a pixel must be to get selected. Secondly can I move all these pixies into another layer/channel or image. Copy, Paste, then in the layer dialog click on new layer == the selection is now a layer.

[Gimp-user] Re: 2.2 splash screen competition
Hi all, After a false start, the GIMP Splash Contest is now officially open! The contest runs until next Sunday, Midnight. Splash screens should be the same size as jimmac's logo and have a pale band across the bottom roughly the same size. Otherwise, knock yourselves out! Competition entries should be attached to the live.gnome.org wiki page at http://live.gnome.org/GnomeArt_2fGimpSplashContest - you will need to create a wiki account. We will definitely have some kind of (small) prize sponsored, details will follow during the week (but the real reason you are doing it is the glory, right?) Good luck to everyone! And don't forget, spread the news!

[Gimp-user] Re: Reducing pixels per inch
[EMAIL PROTECTED] (2004-11-29 at 1021.34 -0500): I have a large photograph that I cropped and then reduced in size. But when I do that the pixels per inch goes up. How do I reduce an image in size yet keep the pixels per inch at e.g., 90? I scanned at 50 PPI (the lowest Xsane will do.) But when I reduce it to roughly half size by resizing the image image-scale image the PPI shoots up to 164. If I reset the resolution to 90 then the dimensions go up. I started with a 10*10 inch image and 90 DPI (so it will use 900 pixels in each dimension). It is big and 90 DPI, and want it to be half size, 5 inches but still 90 DPI. Then in that dialog: 1. Set the units in the top most drop down menu to in(ches), so two top most labels will show 10.000, and the two entry boxes below it will show 10.000. This step is optional, but shows how things change. 2. Input 0.5 in the Ratio X, and as the link button is on, Y will change to 0.5000 as soon as you hit Tab. New Width and Height above it will change to 5.000 automatically. The boxes in Print Size Display Unit frame will too. But Resolution boxes stay at 90. 3. Accept that settings and wait for Gimp to do the maths. Finally check in View/Image Info that each axis is 5 inches at 90 DPI, and logically using 450 for that. Playing with Print Size and Display Units makes one go up when you lower the other, and viceversa, they are interrelated and they are merely the way to access the fields some file formats have to record suggestions for printing. To really modify the pixel data, you have to use the top frame controls, Pixel Dimensions. Instead of Ratio, you can also use New Width and Height in Pixel Dimensions ones. You _have_ to do step 1 so Gimp know you are going to input inches, and then you can type 5 in one of the top boxes, Ratio will be the ones that change to 0.500. As it has been said already, all this interrelations can sound complex, but are useful *, provided you know what will move when you pull from a thread. This could get a video, or some graphical representation of the relations at least: Easy: Top frame sizes Top frame ratios Bottom frame sizes Bottom frame resolutions Complex: Top frame Bottom frame sizes Bottom frame size boxes Top frame sizes if set to physical units * Image from a 3D app or a screen capture or whatever, the point is that nothing matches, it says 1000 pixels, 72DPI and 13.889 inches, but you need 2 inches and 300 DPI. So you set 300 in DPI box (PSDU's W and H will say 3.333), then change top drop down menu to inches and type 2 in PD's Width (PSDU's W and H will go to 2, and PD's Scale will go to 0.600).

Re: [Gimp-user] registry.gimp.org 500 server error
I'd be interested in working on a new plugin registry if the old one is not going to be resurrected (or it if will remain unmaintained even if it comes back up). it now says (in German) that there was a hardware crash, hopefully everything will be online again in a few days (it says Tuesday but not which Tuesday ;-) ...).

Hi, Jozsef Mak [EMAIL PROTECTED] writes: So what should i do? Wait a bit. Unfortunately this story ended up on slashdot and perhaps it wasn't such a good idea to use a Wiki for this since it obviously can't handle the load. My apologies for suggesting the Wiki in the first place. Either the Wiki will come back to live in a day or two or we will establish other means of submission.
