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 1 Replies2 days on GIMP. I need to adjust the clone tool so it's 1080 pixels vertical and about 20 pixels wide. I googled and searched, but I can't seem to find the right phrasing.

I have drawn a 9" circle on a 11" x 11" canvas. I would like to create 45 "tic marks" around the circle at 8 degree intervals. How to use rotation to accomplish this goal?
View 1 Replies View RelatedI have many scanned images of my collection and need to automate the process of rotating the image so that it is "square" and then cropping to remove unwanted background.
I have learned GIMP enough to do this manually with the rotate and crop tools but I have 1000s of images so how to automate this process.
I normally edit with the grid turned on. The rotation guides that show up while using the arbitrary rotation tool clash pretty badly with the grid and disrupt my workflow. Is there a way to turn them off?

I'm trying to line-up two images and the bottom layer is the reference image so I move the top layer in the x,y direction and rotate the layer until it looks good. But instead of saving I want the new x,y location along with the rotation number to enter into an Imagemagik bash script.
I'm using GIMP 2.6.11, but will update to 2.8 if necessary.

i'm trying to make an object have a rotation animation.. i did this by making duplicates and rotating them different angles. When i save it and play the gif, it shows each frame show up and overlay one after the other. I want to only show one frame at a time. How do i do this? Here:

I would like to know if it is possible to do this in gimp:

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 would like to know which tools to improve the border of a small image after rotation. Something like sharpening.
The picture is around 25px wide. When magnified, it shows like this :
The original image pure red and pure white.
The white line, that is a ~1 px from the border is at some points too much polluted by the red color. And the red color is locally too much polluted by the white color.
There is also some aliasing that I want to remove.
How do you see the size of a selection (in pixels?). In Photoshop this would be in the info dialogue window. I'm not finding the equivalent in GIMP (2.6).

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 I could fix up these pictures? Do I need to use a red-eye or noise removal method? I'm using GIMP 2.6.11 .
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.

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 need to do a small bit of horizon straightening on an image which I have.
Using the rotation tool is fair enough.
Under clipping I select crop to result.
In the rotation dialog i enter the angle ( -.7 )
When I click rotate, it goes through the motions of a status bar advancing (green bar), but when it is finished doing its thing the image vanishes entirely, and i'm left with what looks like a transparent background.
If in clipping, I select 'Adjust', it rotates fine but I have to crop the result manually to have the image 'square' with no transparent angled edges.
How the rotation tool works? I'm using Gimp 2.6.4 on Windows Vista.
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. :/
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 RelatedWhen setting up a simple FK control curve on say the wrist for example, many times the control curve isn't exactly perpendicular to the local rotation axis of the joint movement, so when we position the control curve to be perpendicular to the joint - it has a rotational value added, but the rotational handles are lines up with the rotational handles of the joint that we want to move.
Freeze Transformations: then the control curves rotational handle go back to being skewed (out of alignment with the joints)
We want to Freeze transformations before constraining the curve, but we'd really to keep those rotations control handles to remain aligned with the joints rotational handles. This will make it an exact control when animating - grab the rotational handle of the curve, rotate it, and the joint will move exactly in the proper direction.
how to get the rotational handle of any control curve to run perpendicular to the shape after freezing transformations?
I am making a template file having title block with fields. I use this template for creating layouts and sheets using Sheet Set Manager and the fields will be updated from the data of SSM. Now i would like to add a dynamic north block to my template. The block could be rotated (i have this block in file itself) and rotation angle could be inserted. Now how can i add a custom field to SSM so that i could set a rotation angle for the project and thus every new layout or sheet created using the template has the north block rotated with the angle mentioned in SSM.
Here is the file...........
