Here are some brushes at radii 0.1, 0.2, 0.3, 1, 10, and 50.I thought brush radius was measured in pixels, or would at least scale in a linear fashion, but this shows otherwise. Why the maximum brush radius is set to a (small) fraction of the full slider?
I just found the Size slider that's separate from brushes... Woops. Radius slider still confuses me, but it's not a problem anymore. I don't see a delete button around, either. :/
Is there a way to get a brush exactly 2 pixels square? If i set the Radius to 0.7, i get a 3 pixel brush, if set to 0.6, i get a 1 pixel square brush. I mainly use GIMP to touch up scanned in forms and tables and most of the lines are 2 pixels which means twice as much work to correct a skewed line.

View 9 Replies View RelatedI've been a Photoshop user for close to 15 years. I have ver. CS2 and a AMD Athlon 64 X2 Dual core CPU 4200+ 2.21GHz CPU /1GB RAM (6 years old along with the version CS2 running WinXP SP3) I plan on upgrading this year my hardware, OS (to WIn 7 64-bit) and the Adobe Production Premium suite to CS6 (After upgrading to CS5.5 since I am ineligible for the upgrade from CS2. )
One of the things that has always bothered me in Photoshop CS2 was when I set a paintbrush or a blur brush to 300 pixels wide and I'm working even on a small 4x6" 300dpi canvas If I make a brushstroke it takes seconds to make a rendered stroke. I plan on doing digital paintings with a Wacom tablet 8x10, 11x14, 16x20" in size with Photoshop CS6.
I read that as of 2008 CS 3 Photoshop will use the GPU for rendering/processing some effects. Is this true for PaintBrush and blur tools?Granted we are talking about a 6 year old mid-level CPU and now new technology but I would like to know along with using 8 GB RAM Will this 300 pixel-wide brush lag totally change with a Ivy Bridge Intel Core i5-3570K Ivy Bridge 3.4GHz Quad-Core?
Is there a significant difference when using Photoshop with a Ivy Bridge Intel Core i7-3770K Ivy Bridge 3.5GHz Quad-Core since both chips are multicore which Photoshop does usI'm trying to choose my new build and figure out what CPU to get since they are $110. difference. Is is night and day with most of the CPU intensive stuff on Photoshop?
I was using the Gaussian Blur around letters to contrast the background and getting a very wide radius with a very gradual but complete shift in intensity from the edge of the blur to the edge of the letters. That is to say, the blur effect would extend all the way out to the Blur radius fading to nothing and the brightest part of the blur was very near the edge of the letters and not far inside the middle of a letter. That was great!!! Exactly what I wanted!
Then I went to do it again and got the default behavior:
No matter how wide I set the radius in the Gaussian Blur it is still the same width, it is just more faded. And the range of the intensity is dramatically reduced, with the brightest part of the blur far inside the edges of the letters, no matter how much I grow the Alpha to Selection of the letters. Now I am very unhappy.
I tried Reset all Filters, but the 2nd behavior is obviously the default. So how did I do that??? How did I get the 1st behavior? How did I get the Gaussian Blur to extend out so much farther without overwhelming the background? The default behavior of a Gaussian Blur of an Alpha to Selection of letters that are substantially grown is that they completely overwhelms the background and there is hardly any gradient, it is just a uniform halo with little change in intensity.
Gimp does unsharp mask of 0.1 radius, but unfortunately the batch processors only allow 2+ pixel radius. E.g. upres.

View 3 Replies View RelatedI'm using a tablet with gimp and I want to be able to set the brush size for the paint brush and also for the eraser, separately. What happens now is that I'll set the paintbrush size to 10px, paint for a little while, turn the pen over to erase and the eraser will now be at 10px. So I'll adjust the eraser size to something like 50px, erase, turn over, and now the paintbrush is at 50px. Grrrrrrr... I tried creating new brushes for both the paintbrush and the eraser, but there's no brush size option. This is my first time using gimp so I'm probably missing something.

I have a diagram scanned in one pixel mode (b&w). I want to change the line color from black to blue.
I tried this:
In the toolbox I altered the foreground color to blue. In the 'Select' menu I used the 'By color' option. I made sure the settings in the toolbox for 'Select by color' were set at default, then I clicked on a black pixel in the image. The black lines in the image became outlined with a dotted line. I then used the 'Fill with FG color' option from the edit menu. The sample color to the left of the menu item was blue. The image briefly 'repainted'. I removed the selection using 'Select' 'None' but the image lines remain black.
I rotated some pixels, but afterwards when I do something else, the pixels become unrotated. I tried saving the image, but that reverts the rotation, too. Why won't the pixels stay put?

View 5 Replies View RelatedI have a square selection that I'd like to map into a circle of equal size. I see apply lens and map object...sphere, but neither of these seem to do a proper job.
The algorithm I'm after would basically take the pixels of the square and map them onto their new locations within the circle so that each pixel moves inward toward the center until it reaches its appropriate location along the the line from the origin to its radius.
I'm about to the point to just code it in C++.
I've tried adjusting levels, curves, color balance and the heal plug-in, but I can't remove the red blocky pixels in a series of pictures that look like the one below:

how do i get rid of white pixels in the background
I'm working on a very small scale, and need to find a way to make an image which consists of 4 colors, randomly spread around the 16x16 pixels.
I have not been abel to get the desired affect with any of the noise filters, so I was thinking I could make 4 layers, one with each color, delete the parts I don't want and just merge them down.
Now, with such a small scale, I could do the work by hand, but I have to repeat the process at least a dozen times, and I want it to look truly random.
I have an image with an transparent background. I want to change all pixels that are not the background to one color. How do I do this? I can't select the pixels, they as arbitrariliy distibuted. I've played with threshold, but that's not working either. I tried Image-->Mode -> Indexed and then Use black and white palette, but that doesn't work either. I thought i would convert all non-transparent values to black, but instead its picking some threshold and making some black and others transparent. Example file attached.
View 4 Replies View RelatedI've just started playing around with GIMP. I've made two images containing a text to start with. For DPL2.tiff, the resolution (both X and Y) is 72 pixels/in, for DPL4.tiff it is 1 pixel/in.
My question is, shouldn't there be a noticeable difference in quality of the images?
I had a .JPEG of a leaf photographed against a white background. When I went to turn that white background into a transparent alpha channel, it seemed to work okay....except for the fact that when I then went to select the new alpha channel via the Fuzzy Select Tool, it wasn't selecting all these newly transparent pixels.
View 6 Replies View RelatedHow can I control the color of transparent pixels?
I save my image in RGBA (Windows bitmap). The RGB value of the completely transparent areas always turn completely black, and I want to control the color myself.
It may seem pointless, as the color is transparent, but I am using the image elsewhere (for creating mipmaps) where there is interpolation between pixels. Interpolating between 0 and 1 in opacity gives 50%, but the RGB part of the interpolation will mix with black, giving a dark halo.
1.I am working on a project where I need to set all pixels below a level as alpha channel, is there a quick way to achieve this? The level can be both set a prior or adjusted dynamically, the second way is preferred. Right now my workflow includes:1. duplicate layer.
2. use color level in duplicate layer, in menu COLOR -> LEVEL.
3. add alpha mask to original layer
4. copy duplicate layer into the alpha mask of the original.
5. delete duplicate layer.
6. If result is not ok then return to 1.As you can see this workflow is a headache, specially point 6 which is often achieved.
Whenever I paste an image from the internet into Gimp, the image is shifted 3 pixels to the right, and those three pixel columns wrap around to the left side. At the bottom of those three now leftmost columns are a red, green, and blue pixel.
What the bottom left corner looks like:
This only started recently and I can't think of anything I changed recently to trigger it.
I have a big wallpaper and i would like to set the firm logo in the left bodom corner with something like 40 pixel from the left border en 100 pixels from the bodom corner.
View 1 Replies View RelatedI need to create an outline map for another application. The world is demarcated into areas, separated by black lines. The map must only have black & white pixels.
Some questions about using GIMP for this.
1. Is there a tool I can use to make every non-white pixel black?
2. Is there a tool I can use to eliminate isolated pixels of the wrong color (that is for me a black pixel with all neighbors white or vice versa)?
3. Is there a tool I can use to make the black lines thinner? It is desirable in my application to have the lines be only 1 pixel wide
I rebuilt my line on white background from Rich2005 and Ofnuts. My latest version is darker, smoother higher res and wider (see attached).
The problem now are stray pixels, many of them unattached to the line itself. I spent a lot of time with an eraser, but still haven't gotten them all. THERE MUST BE A BETTER WAY!
I found this excellent link on the subject. [URL] RobA even has a script to do what I want. However, I don't think it is GIMP 2.8 compatible, as I can't seem to find it to run it.
The attached graphic, which came from a book on archive.org was originally 520 x 721 pixels. The same graphic was enhanced and increased to 1185 x 1600 pixels (the other attachment). It's clear and bright, and hasn't lost any detail. How this is done?
