Re: inconsitent antialiasing
Hello, I am running gimp 1.0.4 on red hat 6.2 I am trying to make text gifs in gimp, and found a strang inconsitency. If you look at the attached gif, the "T" in "TE" "TA" "TH" "TQ" all look different. I need a context-independent antialiasing solution. It appears that you forgot the attachment but I bet this is what's going on: Antialiasing allows for ``sub-pixel'' rendering. a 50% grey pixel means that half of the area of the pixel has black pixels in it and half have white. Because most fonts dont have intigral pixel width characters, the T can start at pixel x=5 the first time, but then pixel x=18.342 the next time, etc. Imagine this: Draw a box from x=10 to x=20, then one from x=31 to x=41. Scale the image down by 1/3. The box from x=10 to x=20 maps to x=5 to x=10. The box from x=31 to x=41 maps to x=15.5 to x=20.5. Therefore the second box will have a grey pixel on each side whereas the first box will be only black/white. The same thign is happening to you with fonts.

Exactly. How do I do that? =) Use the scale tool or "Image-Scale Image". The answer is so obvious that I still don't think this is what you wanted to know? And that won't stretch it like any ordinary (paint brush) graphics tool would? It would stretch it b stretching it, not like paintbrush does (which I believe is not antialiased.) Gimp antialiases but there is only so much information in an x by y pixel image. I mean an "intelligent" stretch tool. Like you said, not just repeat the same pixels. The best you are going to get is filtering the output of your enlargement which is essentially what you are looking for. Do you know of any software that does what you'r talking about? --Ben
Re: Does this filter exist?
[...] Neither "blow up" nor "stretch pixels" are well-defined terms. What do you mean by them? I would assume that the intended question here is "How do I increase the number of pixels in my image so that the extra pixels are interpolated, rather than simply repeated?" (just to nitpick, when you blow up an image, the pixels are interpolated, not repeated. That's why it looks blury. Without anti-aliasing you do get repitition. What gimp does (more or less) is a simple liniar interpolation to find out what inbetween colors are. IE if you have a black box on white, when you double the size you'll end up with a grey line between the black and white because that pixel would map to between a black and a white pixel.) Exactly. How do I do that? =) I think the ting to do is scale up normally, then use something like unsharp mask to get some detail back. I remember seeing a link (perhaps from this list) that was to information on unsharp mask and an even better shaprening filter someone had made. --Ben
Re: Reverse video
- Original Message - From: Leonard R. Wayne [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, September 19, 2000 10:45 PM Subject: Reverse video Hello. Is there any quick way in GIMP to swap black and white colors in an imported color image? I have a .tif image (generated by another program) which I want to send to my printer. The .tif image consists of a color graph superimposed on a black background. The black background covers most of the image. The graph is labeled by white text which appears superimposed on the black background. The reason I want to swap black and white is that currently when I send this plot to my printer, a ton of ink gets used up in printing the black background. (I am going to be generating a bunch of these plots, so it would be nice to have a way to swap black and white.) Here's how I'd do it: Edit-select by color Select the black color. Copy it to the clipboard. Select the white color. Fill it in black or invert the color (same effect). Paste the black from the clipboard, invert the color (image-colors-invert I think). Finally, line things up if the paste didn't go where it's supposed to. --Ben

Now, here's another question. I am putting black text on white, and using the same font at the same size I get 3 very different letter e's. Take a look at : http://www.bsmanagement.com/llywelyn/images/e.gif Note how different each final e is. Is there a reason for this? This is at 8X display, but it is a little visible at 1X display too. I'm only using 20 pt font. However, reagardless, it does seem as if it should do the same thing every time. Or does it? That would be true except for the fact that the font is anti-aliased. Basicly what gimp does (though it may actually do it slightly differently) is draw a big copy of the font into memory, then scale it down smoothly and draw that. Your font isn't monospaced so the e isn't an intigral number of pixels from where that line of text started. That's why they look different. (I think.) --Ben

It installs no differently (basicly) than any other unix software. You can install it from source or you can also install it from RPM or whatever the package type is for your system.

My lovely airbrushed art is turned into ugly solid (opaque) colour when I save as a png. Is there a trick, or a RightWay, to make these things? Maybe I have some broken software, I am running gimp as per suse 6.4. It depends on what your're using your images for. It sounds like you are seeing your images in 1 bit transparencey rather than full transparency like in GIMP. Is that correct? If it is correct, there isn't all that much you can do about it. If you are doing airbrushing on a transparent image and then viewing it with a program that only supports 1 bit alpha then you'll have to add a background layer and flatten the image in GIMP so that your airbrushing shows up as a color gradient rather than an alpha gradient. --Ben

By the way, does anybody know how to make a 1 pixel width line using "stroke" command? It seems that even if I set my brush to 1x1 pixel the result line will be 2 pixels width. One way is to make image twice as big and then resize it, but, probably it's not the best way. One solution is this: Working with an otherwise blank layer, do the stroke then invert the selection and do ctrl+k to delete the ``outside'' half of the stroked line. It's an ugly way to do it but it works (you can get interesting effects using this with large airbrushes) I too would like to know if there's a way to do it ``right'' if not then perhaps a feature request :-) One other thing I've noticed about stroke is that if you are using a low opacity on your brush, the starting point of the loop is darker (try it with a rectangular selection) I assume this is because it's just drawing the path so the starting point gets hit twice but it's a bit ugly. --Ben alex wrote: Hi, Lars Burgstahler wrote: Hi, I know how to create shapes using the bezier tool.

Convert it to selection and use 'stroke' command ( not sure, but it shuold be in 'Selection' submenu. It fills selection with current brust. 2.
