[Gimp-user] TIFF images and alpha
Hi, I have a problem with The GIMP ... it is performins some undesired scaling of my RGB values when I change alpha value. The situation is as follows. I have an application which can generate TIFF images. If I use this program to generate an image of some color, say RGB = [20, 30, 40] for all pixels, and set alpha = 255 for all pixels, and then load the generated image in GIMP, then everything is fine. Color picker says the color of all pixels is [20, 30, 40], and alpha 255. But then if I generate a new image, exact same colors, but alpha = 128, and load the image in GIMP, then color picker says the color is [40, 60, 80], i.e., double the real values (although GIMP does tell me the right alpha value, 128). I might add that loading the image with 'xv' tells me that the color in fact is [20, 30, 40], even though 'xv' cannot tell me what the alpha value is. If I generate another image, same color values, but e.g. alpha 10, then color picker in GIMP says, alpha = 10, but by now the color values have been scales so much, that the colorbalance is not the same anymore, e.g., RGB = [237, 245, 255]. In this last example I am unsure about the exact result values (I was testing last night on my machine at home, and don't remember the exact values). In summary: it seems GIMP is scaling the RGB values in response to alpha, alpha = 128 leads to double RGB values, alpha = 64 leads to four times the actual RGB values, etc. Have I misunderstood something?

[Gimp-user] 2-byte TTF font brokenness - are there any options?(resend)

The may not display in the message seems to consistantly translate into renders in image as a tiny ugly font like the Windows System font. Is there any workaround for this?

I've searched the web for hours and submitted a bug to Red Hat ( https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=80024 which includes a detailed way to reproduce the problem) all without coming up with anything. I'm not afraid of cvs, compiling, patching, converting the fonts somehow, or whatever, but I have no idea why it's happening or where to begin. Any guidance would be greatly appreciated. -- /chris Programming is a Dark Art, and it will always be.

I have NOT found a workaround for this particular problem, but I have found another way around it: don't use 2-byte TTFs! :) I know that is obvious and what I did was start installing various Windows TTFs so my font selection is now MUCH RICHER and I have no _need_ for the 2-byte TTFs that I wanted to use before because I had only a handful of TTFs to choose from. I've been going to several sites that offer FREE Windows TTFs for download and then installing them in my X font set (using ttmkfontdir I believe is the utility) and now I've got a rich set of great Windows fonts and I don't even both with the 2-byte TTFs anymore. At least, it's worth investigating... :) Peace... Tom ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

Anthony, I tried using the Edit - Stroke command to stroke the outline of a selection. It gave me the message Paint operation failed. Message repeated once. Am I using the Stroke command in a wrong manner? I am using 1.3.10 (compiled from source) on RedHat 8.0 ^^ That is your mistake right there.

[Gimp-user] New Gimp FAQ: Call for Answers
- Forwarded message from Nathan Carl Summers [EMAIL PROTECTED] - This is the the Call for Answers for the clean room reimplementation of the GIMP User FAQ. Please send [EMAIL PROTECTED] a message stating your intent to write an answer, and CC it to the lists so that no one else takes that question. If I do not recieve an answer within three days, I will open that question up again. Once all the questions are answered, I will send a final draft out for comments. The final version of the FAQ will be placed under the GNU Free Documentation Licence. Soon thereafter we will start with the Call for Questions for the Developer FAQ.

[Gimp-user] Question about the Fuzzy Border Script-Fu script
Hi! Ok, I've been beating my head against the wall trying to find out how to do this: 1. take an image (any image) 2. Make a round selection (image/Script-Fu/Selection/Round) 3. Apply a Fuzzy Border to the round selection (image/Script-Fu/Decor/Fuzzy Border) Is this even possible? Thanks in advance!

I don't know how to tell if any given TTF is a 2-byte TTF from a techincal perspective. From a practical perspective, I've found the more fancy or artistic TTFs tend to NOT be 2-byte fonts and I haven't run into any problems with using them. So, I guess the 2-byte problem (until GIMP is fixed or changed) really depends on which TTFs you need to use. Peace.
