[Gimp-user] Color Reduction with GIMP
In GIMP, is there an area where I can lock/remove individual colours in an Indexed colour palette of an image? I was able to see a colour table Dialog in GIMP, where I could edit RGB values and add an additional colour. But I couldn't see anyway to remove colours or lock them from being removed. Is there not something like Photoshop's "Save For Web" in GIMP? Kalle ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
RE: [Gimp-user] Color Reduction with GIMP
The Select Colour tool isn't really supposed to help you in this fashion. The Palette dialog does not help either as I do not wish to change my image into another colour palette. There does not seem to be a way to import my images' colour palette into the Palette dialog, and thus be able to edit that.

RE: [Gimp-user] Color Reduction with GIMP
This method does not deliver what I require. But thank you for helping me learn how to manage palette's. What I need through GIMP is a way to remove individual colours from the image dynamically in real-time. For example, I would click one colour to turn it "off" and see the change to the image. If the image isn't severely affected by turning "off" that one colour, then that colour should be removed. I deal with images that are only 2-64 colours each, and shaving off colours is a huge importance to get the filesize down to the absolute smallest. Currently I use Web Image Guru to do this. Great program. But it costs money. The programmers I work with are all interested in installed GIMP on their machines. So going through GIMP, I haven't been able to easily reduce colours of an image on-the-fly.

RE: [Gimp-user] Color Reduction with GIMP
Once a colour would be removed from the palette, the pixels in the image should change to the closest matching colour in the palette. There would be an algorithm that chooses the replacement colour. If you have seen Photoshop or Image Ready's "Save For Web" feature, you have seen this. You are presented with not only a colour limited (Choose a number between 1 and 256), but it displays the entire colour palette and you able to manually select colours to LOCK or REMOVE from the palette, and you can see the preview of the palette changes on the image before you save. There's an image browser and batch processor called Web Image Guru by Vimas that does this task most excellently. This is what I use on a day to day basis. But it isn't a free tool like GIMP is. The other people I work with are very interested in using GIMP for all our imaging needs... and it does almost everything... except for good colour reduction. -Original Message- From: Andreas Waechter [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 22, 2005 12:18 PM To: Kalle Ounapuu Subject: Re: [Gimp-user] Color Reduction with GIMP > What I need through GIMP is a way to remove individual > colours from the image dynamically in real-time.

Should they go transparent? If so, select by color with threshold set to zero, then clear selection. Should they be replaced by another color? If so, select by color with threshold set to zero, then fill selection with the other color. Or should something else happen to those pixels? If so, what?

RE: [Gimp-user] Crisper screen shots
I can see that fuzzyness you're talking about, and it seems strange that a direct screenshot would result in that... so it may have to do with your export. I looked at one of your PNG screenshots... opening it in Photoshop I was presented with a prompt about Pixel Aspect Ratio. The PNG's you've exported have the "PHYS" PNG chunk in them. This controls the the aspect ratio of the pixels of the image, believe it or not. I think it's supposed to give you control over how an image is viewed on different displays (crt, lcd, mobile phone, tv, etc). Maybe this is having an effect? It certainly did when I opened it in Photoshop. After removing the PHYS chunk, the screenshot looked a lot more normal in Photoshop... but it still had a little fuzzyness. So maybe it's the compression you're choosing for the PNG? All your PNG's are RGB... so that has lossy compression. Are you putting it down a little bit? Since these are screenshots of applications... I would recommend outputting Indexed PNG's instead of RGB. This has some advantages in this case... like smaller file sizes (only a few colours are being used in your screenshots)... plus it uses lossless compression, so your screenshots will not get blurry. Go to "Image/Mode/Indexed" before exporting the PNG. Reduce the colours to what you think is a little higher than what the screenshot is using... hopefully GIMP will detect unused colours and remove them. For dithering options... turn them off unless you have large areas of an image with gradients occuring. When you export the PNG... uncheck all boxes in the PNG options, and make sure compression is maximum. Try this stuff out, see what happens. BTW, search for a windows utility called TweakPNG. It's a great PNG utility... it gives you control over the internal workings of a PNG. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of squareyes Sent: Wednesday, March 02, 2005 4:44 AM To: gimp-user@lists.xcf.berkeley.edu Subject: [Gimp-user] Crisper screen shots Hi all, am making up a newbies help file for Ubuntu, but am not completely happy with the crispness of the screen shots I have taken with "gimp".

RE: [Gimp-user] png compression
There's lots of things you can do to make PNG's smaller. If you save them as Indexed PNG's and reduce the colours, you may end up with smaller filesizes. Change the image mode to Indexed and it should prompt you for number of colours and other options. After exporting the PNG, it still isn't very efficient... most apps like Gimp, Photoshop, Paintshop... they don't do a good job optimizing the PNG export. You may want to try PNG crushing programs that will optimize the PNG much more. Personally I use something called Megaopt: http://www.hydrogenaudio.org/forums/index.php?showtopic=16167 ... it's a DOS script that uses 5 PNG crushers and compares the results. Also, a WIndows GUI program called "PNG Gauntlet" does pretty good too (same as Megaopt almost). Search the net for that. There's other tricks and things you can do... but they only save a matter of 100's of bytes.

GIMP is definately more accessible to developers and customization as well. In Photoshop, I hardly ever use filters.

Well I work on images for cellphone games (PNG's), and there is a lot of attention paid towards PNG chunks, transparency, filesize, etc. In terms of modifying the actual PNG data chunks I use a free tool called TweakPNG to do this. It would be nice if graphics apps like GIMP, Paintshop, or Photoshop would offer control over PNGs just like TweakPNG. As well, reducing colours from a PNG palette by-eye is something I do daily. I use a tool called Web Image Guru to do this. It can also be accomplished in Photoshop (SaveForWeb). GIMP doesn't offer anything like it... the only way to reduce colours of an Index image is converting it to RGB then back to Index, selecting a colour limit and then letting the software try it's best to whittle the palette down (doing it by eye is better). Colour reduction matters when you need to shave off 10's or 100's of BYTES off an Indexed image (one colour removed can make the difference). -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of j Mak Sent: Wednesday, May 04, 2005 12:36 PM To: gimp-user@lists.xcf.berkeley.edu Subject: RE: [Gimp-user] Disadvantage of GIMP when compared to Photoshop --- Kalle Ounapuu <[EMAIL PROTECTED]> wrote: > I've been using Photoshop for a bunch of years and > only recently used GIMP a few times at work. > > Having access to Photoshop and being comfortable > with it, I have no reason to use GIMP.

I also use both Photoshop and Gimp and agree that Potoshop is more user friendly. The lack of a main window in Gimp seems to be a major irritation for new users. That you see all the icons and open windows behind your canvas could be annoying. I've never understood myself why developers haven't designed a main window for Gimp yet.

RE: [Gimp-user] Re: Disadvantage of GIMP when compared to Photoshop
Yea, that's the whole idea. Layer effects/styles save you from having to re-create your effects all the the time... plus everything is cleaner because the "effect" is generated in real-time. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Gezim Hoxha Sent: Thursday, May 05, 2005 4:43 AM To: gimp user Subject: Re: [Gimp-user] Re: Disadvantage of GIMP when compared to Photoshop On Wed, 2005-05-04 at 21:59 -0700, Tom Williams wrote: > If I add a drop shadow to something in Gimp, the drop shadow is in a layer an > I > show or hide.

What if, instead, I wanted to make a bevel depth of a button deeper? The layers wouldn't help me out, would they?

Also support for sub-8bit Indexed mode (e.g. 2bit, 4bit, etc)... currently I only know of Paintshop Pro that can do that (though it's buggy). Another thing I wish for Photoshop is a hard 1-pixel eraser in RGB mode (that acts just like the 1-pixel erase in Indexed mode). Bringing down square brush size to 1 and hardness to 100%, you have bleeding/softness around the area you are erasing. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Alan Horkan Sent: Thursday, May 05, 2005 11:06 AM To: Kent Tong Cc: gimp-user@lists.xcf.berkeley.edu Subject: Re: [Gimp-user] Disadvantage of GIMP when compared to Photoshop On Wed, 4 May 2005, Kent Tong wrote: > Date: Wed, 4 May 2005 03:10:33 + (UTC) > From: Kent Tong <[EMAIL PROTECTED]> > To: gimp-user@lists.xcf.berkeley.edu > Subject: [Gimp-user] Disadvantage of GIMP when compared to Photoshop > > Hi, > > We're an organization promoting open source in Macau.

I'll try and keep this factual and give you information to work with. The scripting infrastructure and availabity of source code is a big factor in making the GNU Image Manipulation Program powerful. It is possible to do batch processing of images but usually people recommend using a tool like ImageMagick instead. Adobe Photoshop also has scripting in the form of Actions. Actions can be recorded and played back which is quite powerful for users but developers will probably find that Script-Fu gives them more control as they can directly edit the files. (I believe they also have a Python SDK but I'm having difficulty finding it.) One of the things I've noticed is that Adobe Photoshop (and the PSD file format) does not allow Indexed images with multiple layers. If you save to any format other than XCF you cannot be sure all features will be supported. There is no version of Adobe Photoshop for Linux (or any Unix with the possible exception of Mac OS X depending on how you look at it) and although Adobe Photoshop version 7 has been made to work with Wine http://winehq.com there were problems getting more recent versions to work. Many users with dual-head setups say they much prefer having seperate windows and use one screen for the image and put the palettes on a seperate window. Some of the people who do not like how the GIMP manages windows make use of the Deweirdifyer to give them a back window (and others use Xnest, or multiple workspaces) http://registry.gimp.org/plugin?id=3892 If you are using the GIMP on windows (and this only works on the windows version) you can get PSPI which is a plugin which allows some types of third party Adobe Photoshop plugins to work with the GIMP. > As I'm not a graphics guy, I've got a colleague to do some initial > evaluation.

Your colleague might have a more comfortable experience if he used the Photoshop style keybindings for the GIMP (replace the menurc file with the psmenurc) but in the long run that might be counterproductive if you really want to learn how to use the program. The GimpShop project may also be of interest to your colleague but hopefully in the long run the best ideas from GimpShop will be incorporated back in to the GNU Image manipulation program. http://plasticbugs.com/index.php?p=241 > -- Compare to PhotoShop, creating text effect is difficult.

RE: [Gimp-user] Disadvantage of GIMP when compared to Photoshop
Yea it's a very uncommon thing, but I am working with J2ME apps for mobile phones. Part of making an app smaller in filesize or take less memory on a mobile device is to optimize images and explore different image types. Some apps we've come across have code that specifically needs something like an image to be e.g. "2-bit grayscale" in order for something to happen (or another example having to do with palettes... that it requires colour "3,3,3" to be in position 4 of the palette). I would appreciate sub-8bit support in GIMP... it would definately be a reason for me to use the program more often. Not many people would need this kind of stuff tho =). -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Joao S. O.

Nobody have asked, that I recall, saving in indexed formats with 2 and 4 bit. This is not hard to do code in the GIMP PNG and maybe some other format.

RE: [Gimp-user] when even free advertising fails
The bug-tracker serves it's purpose, but you can't expect everyone to be reading it over before making any comment about GIMP. Maybe there are GIMP users who would love everyone to drop Photoshop (or whatever) and use GIMP. If so, they will have to deal with more of this. Not everyone can spend the time to search something out, or in fact they don't care, they would rather voice it out right away. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Sven Neumann Sent: Friday, May 06, 2005 2:49 PM To: Gezim Hoxha Cc: gimp user Subject: Re: [Gimp-user] when even free advertising fails Hi, Gezim Hoxha <[EMAIL PROTECTED]> writes: > On Thu, 2005-05-05 at 07:04 -0700, Carol Spears wrote: > >> a forum where they can constantly bombard and belittle TheGIMP and are >> free to do so and the best they can pull out of their over-extended >> reasoning is this layers effect stuff. > > I'm not sure who "they" are, but if you're referring to people in this > list that are not afraid to admit gimp's weaknesses, these people have > every right to point them out.

[Gimp-user] Cannot paint on transparent layer?
When I create a new transparent layer I can't seem to paint on it with the Paintbrush. When filling the layer with color (fill tool), now I am able to use the Paintbrush. Do I have to do something after creating a new transparent layer to be able to Paint on the transparency with the paint brush? Thanks, Kalle

One thing that just came to mind... in Photoshop you can adjust brush size with a slider bar. In GIMP, I don't see a way of adjusting brush size on-the-fly. Please point it out to me if I am missing it. About brushes... Corel's Paintshop Pro and Painter seem to have much better on-the-fly brush settings than Photoshop or GIMP.

On my PC with Photoshop I simply press Print Screen on my keyboard, go into Photoshop, make a new image and ctrl+v to paste the screenshot. When making a new image (e.g. File/New), the screenshot dimensions are automatically detected. If I didn't have this basic "PRNT SCREEN" capability working, or I wanted a more automation with multiple screenshots, I would probably use HyperSnap DX or some other screenshot program.

It's strange that you get no dialog when doing the basic "Sharpen".
