I've got a question about canvas rotation. Everytime I I try to totate the canvas arbitrarily the qualtiy goes way down, but if I rotate it 90 or 180 degrees it doesn't change. Most of my images need to be rotated 45 degrees. Is there any way to keep the image quality from going down or a way to fix it?
View 9 RepliesWhen I scan my photos they are not always straight. I use Image-RotateCanvas-arbitrary command to change the percentage of rotation to straighten image.
I automated the process in "actions" menu to rotate canvas 0.5%CW and 0.5%CCW.
I decided to play a little bit with newly made "action" hotkeys to get used to them.
Now the problem
When I rotated the image 5 times CCW and 5 time CW I noticed that it became significantly distorted, blurred. I tried manually do the same (without automation) same result. With every additional step of rotating, image becomes more distorted, so it is not faulty automation...
Question:
Is it normal?
P.S. I scan images at 24 bit color, 150 resolution.
I have some 300 images, all handheld shots done in an on-location studio set. They all need varying amounts of image rotation since they're handheld. There's a beaded curtain in the background, so manually I use the ruler tool, draw a line along a strand of beads, and then image/rotate/arbitrary.
I need to create an action that will (1) do the arbitrary rotation and then (2) save and close the file.
However, when I record this, the value of the rotation of the sample file I'm working is what gets recorded (not surprising). In other words, if image A needs 0.28 degrees of rotation, that's not what I want for image B which might need -0.15 degrees instead. The action recorded 0.28.
Is there a way to create an action that will simply rotate according to the ruler once I've drawn it?
i am looking for a command that will let me take a scan of something and say "make vertical" and have PS prompt me for two pickpoints with the second pickpoint being directly above (i.e. vertical) the other. alternatively i would like to have a way to "make horizontal" and pick two points that i want oriented in a horizontal line to each other.
right now the way i do this is to rotate clockwise or counterclockwise by 90 degrees, then rotate by some arbitrary amount like 3 degrees, and then to do a series of 0.25 degree rotations - as i check by running a rectangular border top to bottom (or right to left) against something in the image until it is almost correctly oriented.

Image is rendered sharp at the predefined zoom levels (like 25%/33%/50%/66%).
Then if I zoom to eg 55% the image gets blurry.

The number of pictures is relatively small (less than twenty), and I will have to manually select the area to be cropped. But, I don't see how I can crop to, say, a hexagon repeatedly. What I would like is a cookie cutter so I can simply size the shape and then stamp it out.
View 1 Replies View RelatedBasically, I want to be able to create a glass effect on a square icon tile. I want the glass to be translucent so that the image behind the square icon tile is blurry (hence the translucency). I know how to create effect if I want it over some user-defined background layer, but what I am trying to do is a bit different. I need to import a PNG file into a theme program, and it uses this glass tile. I want the glass tile to have the translucent effect, but the problem is, I can only get the effect to work if I create a layer over a user-defined background layer. What I want is to have the translucent effect over whichever background is used in my theme program. I am not sure if this is possible to do with a PNG file, or even possible at all. If anyone could shed some knowledge on this I would greatly appreciate it.
View 4 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...........
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 9 Replies View RelatedI have some UTM images that I need to convert to State Plane. If I import them into map with raster design and export them to the state plane coordinate system, they work just fine, but I can't figure out a way to get rid of the black wedge that it makes along the edges of images.
If I query them in using map I can transform the coordinate system, but then every time I open the drawing it takes like 5 minutes just to open.
What has everyone else done to use multiple images in a drawing and transform or convert the coordinate system of the images?
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 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 am trying to make the image fit a rotated face that is usually of the same proportions as the image.
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.
See three small bitmaps attached: <<original.bmp>>; <<45cw.bmp>>; <<45ccw.bmp>>.The original is a simple 21x21 pixel test pattern, black except for white pixels in the center and corners. It's appearance should be the same whether rotated 45 deg clockwise or counterclockwise, and the appearance should keep the symmetry of the original.I used "Bilinear Interpolation".
I used a gamma = 1 profile, and to be extra-safe set Edit>Assign Profile>Don't Color Manage ...I set the background color to black in the toolbox. Thank you John Joslin.Then I rotated the original image 45 deg clockwise and counterclockwise to make the other two files. Why to the resulting images look so different? Why are they lacking in symmetry? With the other interpolation methods too, clockwise and counterclockwise rotations give quite unlike images. A partial explanation could be that Photoshop rotates about a point not in the image center, but this doesn't explain enough.
I tried 20x20 patterns which showed similar problems. I'm mostly interested in bilinear interpolation because this is supposed to conserve the total pixel value. Each white pixel in the original has value 255, so the blob resulting from this pixel should have total value 255. Look at <<45cw.bmp>>.The blob on the left has total value 69+94+13+5+18+1=200. The blob on the right is an almost perfect antipode with total value 1+18+6+13+95+68=201.Â
The blob at the bottom doesn't resemble the side blobs and has total value 42+56+40+3+55=196. The blob at the top has total value 40+41+56=137. Clearly Photoshop has lost the top of the top blob. (It also does this with 45 deg counterclockwise rotation, and also with 135 deg rotation.) The blob in the center has total value 49+49+48+47=193.Â
All of the blobs fall far short of 255. Photoshop might be excused for messing up edge pixels, but not a central pixel. Photoshop messes up rotation at the single pixel level. I made a test pattern with clusters of 4 white pixels and the rotation of this did conserve the total value for the central four. Edge pixels still showed problems. Photoshop image rotation appears to be based on sloppy code.
Is it possible with X5 to rotate a video arbitrary number like 8%? I know the video can be rotated 90% but unsure about just a minor rotation. If not possible in x5 maybe in x6?
View 1 Replies View RelatedIs there a quick way of achieving the following:
You have an object rotated at an arbitrary angle
You want to rotate it back to a 90 degree line by snapping it.
I can do this by measuring the arbitrary angle and then rotating it manually based on my measurement.
I have a line (not a polyline) that i need to extend by dragging one end to an arbitrary location but must conserve the orientation of the line. I then have to drag the other end point in the opposite location to a location that I pick (ie, not a cad feature, but by human eye)
POLAR works good in that i know the angle, but the line is allowed to be drawn wherever, and i need to focus on precisely where i extend the line too and not that the angle is changing.
What i'm looking for is the equivalent of using "Path along text" (in this case for a circular path) but using already rendered bitmap data instead of text and a font. Why i need to do this is: 1. i don't have a font for the logo text i created (i don't think one exists) and 2. i would like to add some effects before "wrapping" the text around the circle.
I'm having so-so success with "distort -> polar coordinates" .
In the Print module (LR4.3) under Layout, the unit intervals for margins and cell size seem to be arbitrary. For example, I can get margins of 0.93 or 1.03 inches left and right and 0.94 or 1.06 inches top and bottom, but not 1.00 inch all around. Similarly I can get a cell size of 4.02 x 6.04 inches or 3.93 x 5.95 inches, but not 4.00 x 6.00 inches. why Lightroom offers such seemingly arbtrary measurement intervals or what controls the intervals?

I got too smart for myself today in bringing an old drawing up to current standards...Everyone seems to want their block attributes to be zero - I have blocks where the attributes are best when they match the rotations of each blocks.
I have an old drawing that was rotated (as it should be) at approx 2deg.
I used a lisp routine to global edit all the blocks that needed to be at zero. BUT for some reason (and after hundreds of blocks were corrected), I noticed I now have two blocks that should NOT have been in the set have had their attributes rotated to zero....and the attributes should be at the same rotation as their block's rotation.
Because those two blocks have a fixed tic mark, I can click on the mark to see what the block rotation is, then rotate its attribute to that rotation, but I have hundreds of blocks! One-at-a-time sucks....
Any chance there is a GLOBAL way to edit an attribute rotation to match its own block's rotation?
I've been trying to model cut produced by a ball end mill taking an arbitrary 3D path. I know how to do this for 2D paths (and this has been discussed a couple of times on this forum), but I have had little to no success extending this to paths in 3D. I've attached an Inventor file that demonstrates what I want to do, it has an sketch that describes the tip of the end mill and the path that I want the center of the tip to trace out.
This seems like something that should be possible using sweep feature, but if it is then I have not found a way to get this to work. The issue is that I have not been able to effectively control the angle of the sweep plane with respect to the path. In reality, the normal of the plane should be equal to the tangent of the path with the z-component zeroed out.
However, if I sweep using the path and the "Path orientation" then it does not zero out the z-component, if I sweep using the path and the "Parallel orientation" it does not take the x&y tangent components, if I sweep using a guide rail or guide surfaces it also does not zero out the z-component.
In fact, the only way I could come up with to accomplish this would be to sweep the path in 2D and then to use a series of bend part features in order to put things into 3D. So far as I can tell this works, but back calculating the 2D curve is so backwards and laborious that I can't imagine using this for anything. In Solidworks this is relatively easy using the sweep solid feature .
is there a way to rotate a layer in photoshop on the x and y axis like after effects? can you explain me how can i rotate the layer or an image like in AE?
View 5 Replies View RelatedI created a simple shape in Photoshop I then edited the shape using the Repoussé dialog. I simply extruded the object. The default extrusion depth setting of 1.0 was far too deep for my needs so I changed the depth to 0.07. It looked good. Next I wanted to animate my simple hexagon shape rotating about it's z axis.
So using the animation pallet, I set a key frame for 3D object position at zero and then I advanced the timeline to 3 seconds. With the roll 3D object tool selected, I edited the z axis orientation in the tool bar from 0 degrees to 360 degrees at the 3 second mark. I then played my animation and while the object spinned about the z axis, the position of the z axis was in the wrong place. the z axis was still aligned with the center of my extruded object if the depth had been set to the original depth of 1.0.
End result is it looks like my shallow depth hexagon is rotating about a point in space rather than rotating about the center of the object. Is there a way to reposition the axis so the center will be the center of the depth of my extruded object? In shots 1 and 2 you see the object with the correct depth but the wrong z axis location. In shots 3 and 4 the object has the wrong depth but rotates properly.
