I use the ruler tool a lot and hate the way it keeps reverting to the eye-dropper tool in the toolbar all the time! Is there a way to stop this from happening? If you use the ruler tool, then some other tools all seems okay until you save the image - at that point the ruler is replaced with the default eye-dropper tool. Therefore if you want to use it again you have to select it again which is a pain. Most tools seem to stay as they are when saving except the ruler. This was the same in CS3 by the way. I was hoping this might have been fixed in CS4. I'm using CS4ext in Vista Business.
According to Adobe Photoshop CS3 Classroom in a Book, there's a ruler tool hidden behind the Eyedropper tool. All I see are the Eyedropper tool, the Color sampler tool, and the Count tool.
I need to show specific ratios on the image, e.g., this distance is to this as that is to that. A measuring tool that works in pixels is pretty cumbersome. IS it possible to re-calibrate the ruler tool to measure in millimeters, centimeters, etc.? Pixels don't really make it for me. It seems like an obvious choice, but I can't figure out how to do it.
The problem with the ruler tool is that when I select another tool the former DOES not stay visible. something I need. Â For example, I make a measurement with the ruler tool, then select the move tool and the mesurement made dissapears from the document
I like the features built into the crop tool since CS6, but I have one major issue which I can’t seem to find any comment or resolution on. Basically, if I rotate an image using the crop tool, I find horizontal and vertical lines tend to be jagged, as if very rough anti-aliasing had been applied.  If I rotate the same image using the ruler tool, vertical and horizontal lines appear smooth and correct. They actually appear straight, not jagged.The result is I have to leave the crop tool, jump into the ruler tool, make my rotation (which is nearly always bringing a vertical or horizontal back to true), then back to the crop tool.   It first appeared in CS6, and now I’m using CC it’s just the same. Is there a fix, am I doing something wrong?
When I am trying to straighten an image with the ruler tool, I keep receiving the following error: Â Error 8800: General Photoshop error occurred. This functionality may not be available in this version of Photoshop.
- The command "Set" is not currently available.Line: 254->Â app.activeDocument.activeLayer.isBackgroundLayer = false; Â I don't understand why this isn't working because I have used this feature before.
One of my students was using the Ruler tool to straighten an image. Her image kept flipping way off the canvas to one side, even though we checked to make sure her reference point for rotation was in the middle of the image (it was). Â I can't duplicate the mistake or find any other complaints about/reference to it .
I have created a custom measurement tool to measure distances (captured from sattelite imagery, and using the distance key as the guide) and it works great. However, I would like to be able to use the same tool to measure curves/radiuses. Say for instance a mountain road. I know the scale of the photo, and can measure any straight (line) angle, but can I do the same for a curve or radius using the same scale?
I'm trying to access the ruler tool in elements 9. I got to the eyedropper icon, point at it, click and hold, but the window with the options does not open. Is there another way to access this tool?Â
I need to make a ruler in 1/32nd increments 4 inches high and 1/2 inch wide, I've tried going for help in other places but I'm such a newb to PS that I can't get it to come out right.....
when my ruler is set 1:1 that the scale does not give an accurate reading when I place a ruler on screen and measure it. Can this be corrected or am I just being daft.
I frequently use a flatbed scanner to capture images of them. I normally import the scan into Photoshop and tweak it before saving.
I'd like to also be able to easily put a ruler in the scanned image to show the size of the item scanned. A layer that was transparent except for a ruler that ran along the sides and top of the image would be perfect. Can I create such an image and then paste it on top of each scanned image?
Is there an easier way to do what I want to do? Maybe something already in Photoshop, or some kind of plug-in?
I need to make a ruler in 1/32nd increments 4 inches high and 1/2 inch wide, I've tried going for help in other places but I'm such a newb to PS that I can't get it to come out right. specifically I asked for help here but they don't seem a very friendly place for newbs. Some of you guys can probably whip this up really quickly, would you mind emailing me the PSD file at gjowen@knology.net, can you put a black rectangular border around the ruler so I will be able to cut it out easier?
Something that has always bothered me since Photoshop's beginnings was that in high resolution files, at extreme screen magnifications, you can't measure using the rulers easily. In other programs, as you magnify the image on the screen, the ruler marks will keep reading their measurements. In Photoshop, you only get the full inch readings, not fractions of the inch. So if I want to draw a guide at 1/16" or find something at 1/16" in Photoshop, all I see is:
You have to shrink the image back down to find the 1" line and then zoom back and count the fractions to find the one you are looking for. I know you can use the ruler tool, but let's say you want to paint, or select starting at 1/16". Using the ruler tool becomes problematic, when all you want to do is see where 1/16" is on the screen.
In CS4, I could crop a larger picture to a size such as 9"x12" without actually resizing it, just eliminating the unwanted areas. It seems this is no longer possible as now when cropping, the positions on the rulers are not marked as I determine the crop size. So I can set the size to be 9x12, and whatever crops will expand to that, I assume with interpolated pixels and possible detail loss.  If unconstrained is used, then you don't know what the size will be till the crop is done and it realigns with the rulers.
Before, I could either enter the numbers, such as 6" 8" 300dpi, if I wanted to enlarge a smaller image, as I still can do now. But also, with CS4, I had made a preset with no numbers, similar to unconstrained, but with the positions showing on the rulers, so I could draw to whatever size I wanted, within a larger image, so when a crop was made, area was removed but there was no re figuring of the size. This is more like cutting out a picture on paper, while now it seems only a stretching of the area can be done.
I like to set lines for cropping on the canvas. The vertical ruler is perfectly accurate. The horizontal ruler is off by alot. This is on cs4. The canvas size is adjusted to be A2 (420x594mm) The crop marks are with the ruler in inches to 16x20.
The ruler scale isn't proportional on my screen for the height and width. The canvas size is only 3 x 5, so I don't think it's because the file is too big. The file looks great on screen, but when I print it out the image proportions I see on the screen aren't the same as the print out. When I look at the ruler, an inch is much longer on the height than it is on the width. I'm viewing in Print Mode, but have also tried fit on screen and actual pixels (which makes it too big to see, of course). I tried resetting all tools, but no luck.
I was under the impression that the rulers across the top and bottom of the canvas were measuring the length and width of the window at the given resolution.
However, this can't be the case, because I notice that when I crop a photo down from a width of 70 to a width of 20 on the ruler, when the crop finishes, the width of the canvas is back to looking like 70, so the ruler is not absolute, but some kind of relative measure? And is there a way to get an absolute ruler either of any unit?
If i open a new .psd file of any size and i have guide lock on, I get lock lines as i move and object twards the center of the canvas. Â So how do you get ps to place guides (H&W) at the center of any doc. Â The guides do not lock to a center when i pull them from the ruler. I can not figure out a way to make the ruler show zero at a center point and go =/- out from a zero center point like a number line either. Â So, How do i find the center of a doc?
I cannot find the time ruler on my screen or where you can add it in. There is simply a slider, with no ruler underneath it. Where can I find this feature?
I was wondering if it was possible to change the origin of the ruler?
I have a template page I'm trying to set up where I have guides placed roughly an inch into the paper. What I want to do is change the ruler so that the origin, that is point 0,0 , is at the cross hairs where the vertical and horizontal guides meet.
What I want to do is make a Ruler. In particular a Ruler that goes up to 360. This is going to be a Liner Setting Circle that I am going to use to wrap a Dobsonian Base with. So these are going to be in Degrees.
My plan was to try and break up each degree in to 20 increments. I was hoping to used the (Filter>Render>Pattern>Grid) feature to do this in layers. To have 3 Layers overlapping. One are 360 for the main degree marks. One at 3600 for the increments of 2 between each degree. One 7200 for the increments of 1 between each degree.
