GIMP :: Rotation Around A Circle
Nov 16, 2012I 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 RepliesI have a block with a rotation parameter/action. I can't seem to get the rotation "circle" to stay in the same spot relative to the block when I rotate. Example: I make a block of a circle. Go into block editor and put a rotation on it with the base point in the center. Move the blue rotation circle to the center. Close block editor and do a rotation. The "rotation pick circle" will not stay in the center of the circle.

Telling the canvas to resize to the picture doesn't seem to work for me.

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 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:

or this:
clone and rotate the cloned source:

if its possible, how do I do it?
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.
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.
When 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...........
To summarize: It seems that compounding a path resets the rotation of the gradient to it's original degree of rotation.
Detailed version:
1. Create a shape.
2. Add a gradient fill. Note it's degree of rotation. Let's say it's set at 10°.
3. Now rotate the shape by any means (transform or rotate tool). Note the gradient degree of rotation has shifted the same amount as the shape was rotated (if it was rotated 50°, the gradient will show at 60°).
4. Make it a compound path.
5. Instantly the gradient shifts back to it's original degree of rotation of 10°.
It appears that when rotating a shape with a gradient, the rotation of the gradient is locked to the rotation of the shape. But when making it a compound shape it releases that lock and "remembers" it's original state. But that is only true as soon as you make it a compound path, but if you no go ahead and rotate it just a bit using the cursor (as opposed to selecting transform > rotate), the gradient will switch back to how you would expect it to rotate in the first place...
Workaround would be to make it a compound path before rotating the shape at all.
I want to rotate a drawing in my paper space, but without rotating it in model space. So that I still can work on it easily in model space.

View 3 Replies View RelatedI have a North Arrow that I would love to make into a dynamic block. I would like to be able to rotate the N that represents where the north direction is. But while rotating the N around the center of a circle I would like the letter itself to stay un-rotated. It seems simple, if I rotate the letter around the axis of a circle 90 deg, I would like the letter itself to rotate -90 deg on it's own axis. Of course this is easy to do manualy, but how do i do it so that rotation 1 automaticaly triggers rotation 2?

I tried to draw a circle, but I don't know how to put this image inside the circle. Or maybe just easilly crop as circle, how can it be done?

I've worked out that I can copy and paste the layer, click on the rotate tool, set the center, rotate it by a fixed amount, fix it, and repeat a good few times, but that will be really slow. Is there a faster way of doing it?
I'm relatively new to gimp and I need to know, how do I make a clean circle? I know how to make a circle, but I would like to make it so that it is not pixely on the outside. Is that at all possible?
View 1 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'm trying to put a text around a circle / arc.
I'm able to create an ellipse with the select tool, create a path from it and then add a text "along the path". Unfortunately I can't specify on what position of the arc/ellipse the text should start (left-upper corner, middle, right upper corner, etc.).
So i want to cut a coin out of a picture and export it to a picture with the sidelength being the diameter of the cut out coin. How am i able to save it in a new picture with that size without the white space around it?

View 3 Replies View RelatedI was merrily cloning away and somehow or another my clone tool changed into a very thin elipse rather than a circle. I didn't knowingly do anything to make it change.
I then made sure it was on the round fuzzy tool brush - but it insisted on making an elipse.
About a year ago I created this picture using gimp (ignore the text) .
My problem is that I have completely forgotten how I did it and now I need to know how.
So how to create the blend effect in the upper right of the circle (again don't worry about the text)?
In gimp, some things are confusing. like the shear/skew tool, isometrics/pixel grids, and selecting objects.
Is there a way to skew a circle for isometric pixel art (30 degrees)? Does gimp have a isometric/pixel grid? (there's a regular grid, but its not isometric)
when selecting an object, is there a way to select it without using float every time? Lastly, is there a way to constrain a line to the 3 most used isometric lines used in isometric pixel art? (shift works, but its hit or miss)
It seems that I have accidentally changed a setting but I don't know how to fix it. I am trying to create a circle with a thick edge/border,like this My link I am going to have text in the border. It worked fine as in previous pic but gimp wont let me do it anymore.
When I try to create a circle with wide edge now the shape completely changes to a diamond type shape My link It's not a circle anymore! I am guessing that I must have changed some setting but don't know how to fix it. I am using windows vista and gimp 2.8.4.I
I was wondering if there is a way to bend a music manuscript into a full circle?
I have tried the warp and bend/curve filters but cant seem to get the effect i want.
