Now I need to make the white transparent. Is there a easy way to do this. At the moment I copy the picture and paste it into a new bigger picture that is transparent then I use the eraser to erase pixel for pixel. My second problem is that when I save it to png and open it with IE5/NC the transparent displays black also when I flatten the image the transparency becomes black. How do I get a picture to display transparent in IE5 and what does flattening a image acctually do. Thanks Any help would be much appreciated. Cheers Gerhardus Geldenhuis

I would be most grateful if any of you can give me some ideas or point me to some source of help about the solution of this problem. I have just browsed through the avaiable plug-ins in GIMP but it seems that none of them can solve my problem. I want do image analysis of some colour logos. I try to scan some logos from magazines, books, promotional brochures and catalogs. Perceptually, these logos are very simple and usually contain several patches homogeneous colors. My image analysis software depends on this assumption to be successful. However, in practice, the scanned images might have many pixels with very different colours due to the following possiblities that I guess: 1. Dithering when the publication is produced 2. Anti-aliasing effect when the publication is produced 3. The texture of the publication paper I want to do automatic or semi-automatic pre-processing with GIMP so that the above three effects can be removed before my image analysis algorithm is applied. I have no idea on how to do the preprocessing efficiently and accurately. Could any one give me some ideas of how to perform the above three tasks efficiently and accurately? Thank you for your attention. Kent.
RE: Making Transparent from Non-Transparent
Under linux at least, there's a plugin named colortoalpha (i dont't know where in the menu exactly, i believe under Image/Colors, search in the PDB) that can be good for this. -Message d'origine- De: Jonathan Gift [mailto:[EMAIL PROTECTED]] Date: vendredi 12 janvier 2001 13:34 : Gimp Objet: Making Transparent from Non-Transparent Hi, Second big question is I have a lot of old logos Istored on a black background.

Hi Seth, just a few questions, if I understand you correctly: you wrote: I would suggest using Guides. To use a guide, drag it out from the ruler and place it where you want a boundary to be. That means, if I create a new Image, I can use the rulers at the sides of my new image to get a guide, or do I have to go into the menue right mousebuton-guides-guides grid? I tried to follow your suggestion that way: I draged a line (what seemed to be your mentioned guide) out of the ruler, by pressing the left mouse button at the (0;0) coordinates of the rulers. I noticed that I just get this line, when I start at the (0;0) point of the rulers. Now, when I place the mousepointer on this line and start drawing a new circle, it snaps to this line, but when I start drawing a circle anywhere in my new image, it doesn't snap to it. The same with selections. When I select a drawn circle it doesn't snaps either to the line. It would be nice, if you could tell me, if I did it the way you meant it? BTW, with your method I can get to circles who start at the same spot, but I like to have two circles, that have theire center exactly at the same spot, where the center of my whole image is, any idea? Thanx for your help, Dominic

color palette in context of graphical charter
In "color selection" dialog, there's a watermark tab that permit to store 10 diffents colors. It's very intersting to preserve a graphical charter. Is there a possibility to save this "palette" of color in a file. Because, when you quit The GIMP, these palette is cleared. The "top" (as we say in France) should be that this palette should be saved in the xcf file. Regards.

RE: apply a channel
Hello mike, First, thank you for your response. But no, it doesn't work, i've already tried this before. I will try to explain better myself , using an example: Imagine you've a photo of a crowd. You want to show up just a face on this photo. So, you create a semi-opaque channel. Then, you select the face (channel is seleted), perhaps feather it and then you cut it. Result: the crowd is in "darkness" and the face you've selected is in normal light, because there's a hole in the channel. It is this effect i can't save. I've inserted in this message a little xcf file to illustrate this. Can everybody try to make jpg, bmp, ... file wich is exactly the visible representation of this file and say how you've made (the "grab window" method is not valid because the image i want to save is bigger than my screen :-[ Thanks in advance. -Message d'origine- De: Mike Peters [mailto:[EMAIL PROTECTED]] Date: mardi 31 octobre 2000 16:58 À: COUTIER Eric Objet: Re: "apply" a channel COUTIER Eric wrote: I know this.

Text and floating selection
Hello everybody, I want to do that: 1- Text tool 2- "Bla" (enter) 3- "Bla" appear on the image 4- "RightClick-Select-"Save to channel" It's impossible. I think it's because the selection is "floated". Finally i've found the solution. 1- Text tool 2- "Bla" (enter) 3- "Bla" appear on the image 4- switch to "LCP" window 5- Double-click on the "Floating selection" layer then press OK 6- Right click on the layer name "Add layer mask" 7- Choose "Layer's alpha channel" 8- right click on the layer name 9- mask to selection 10- switch to image 11- right click 12- "save to channel" or "To path" But, is it possible to have a checkbox to specify "floating selection" or not then we use text tool ?

Impossible to move the layer
Hello everybody, I've noted that the original layer is impossible to move. When you click on the layer in the layers window, the "bottom" and "top" arrow are grayed (even if you've created another layer in the image after). The only way i've found to can move this layer is to duplicate it then delete it. The same thing occur in Paint Shop Pro but when you rename the original layer (for example from "background" to "toto layer"), then you can move this layer. Perhaps it's a good idea, no ?

Make sure you have the 'patch' utility on your system (I'd be surprised if you didn't already have it). Download and unzip the patch. Change into to the directory containing the old gimp source. Then just run patch -p1 patch-name.diff (inserting the appropriate patch name). The -p1 tells it to strip off the first part of the directory name in the patch file, because whoever made the patch may well have a different dir name than you do.

Suggestion to toolbar buttons placement
Hello, GIMP: what a great tool ! I am just an user but can i make a suggestion ? There's 25 buttons on the Gimp Toolbar and sometime, it's not easy to find the good one in all these buttons. I suggest to arrange buttons by "groups", separated with spaces, to respect "7 items" ergonomy standard - selection buttons:Rectangle, Circle, Freehand selection, magic wand, bezier tool,intelligent scissor, selection mover - "transformations": crop tool, transformation tool, mirror tool - drawing tools: text tool, fill tool, gradient tool, pencil, brush, rubber, aerograph, ink tool, - rectification tools: stamp tool, blur tool, ink tool, multiply tool, finger tool - "gadget" tool (tool that don't modify image but give info on image):magnifier, compass, color picker I think with that, each button must be easier to find.
