I'm not sure of the correct terminology so please bear with me. In CS4 when I zoomed in on an image, the bar at the bottom would show the size of the image now on screen relative to the full size. i.e. if I go from 50% to 100% the bar would be half the size indicating that I am only seeing half the image. At least I think that was the case in CS4.
Here's and example from CS6.
How do I make the bar indicate the true amount of zoom, and how do I get rid of that grey area?
The images may be displayed smaller on the Forum, but by clicking them one can usually view the full image.
I work with Photoshop CS6 on Mac OS 10.6.8, too, but I don’t seem to be able to reproduce the behaviour.
What have you done trouble-shooting-wise so far (OpenGL, Preferences, …)?
The problem is to do with Preferences > Interface > Open Documents as Tabs. When that option is ticked, I get the strange behaviour in the scroll bar. When that option is unticked, the scroll bar works as it should, but new images open in a new window.
I'd like new images to open as tabs and each tab show the size of the image in the scroll bar correctly.
I've also noticed that Preferences > General > Zoom Resizes Windows doesn't work when tabs are selected. The window always stay the same size, and I assume, cause the incorrect bar size in the scroll bar. Maybe Photoshop thinks the window is resizing when it isn't.
In CS4 it bothered me that if I resized one tabbed image (because I had chosen to Resize Windows), all the other tabbed images would also have resized windows. At least I think that's what happened. Maybe the designers tossed that idea and a tabbed window now always stays the same size, but they forgot to alter the scroll bar size.
Anyway, I think my CS6 has a fault. This is what I did:
Now the interesting thing is, that last size sequence is non-linear. It looks like PS is doing calculations based on incorrect numbers but in a convoluted way.
Can anyone reproduce these results?
Yes, it's working as designed.
There's a feature called "overscrolling" which allows you to scroll past the edge of the document, and it's only available when the document is larger than the displayable area. You'll see it work if you zoom an image to be *just* larger than your space and use the (what seems like too-short) scroll bar.
This inconsistency, between when the document will all fit in the displayable area, and when it exceeds the space, is the real root of the problem.
People have complained about this for a long time, and Adobe doesn't listen. Thing is, some folks would like to be able to scoll or pan to offset an image that DOES all fit so as to be able to comfortably sketch on the edge - or for whatever reason. That would make it more consistent.
Here's a reproduction of the problem, and scroll of the image that's slightly bigger than the window to illustrate:
Here the image all fits - no scroll bars:
Here the image has been zoomed in a little more - the scroll bars have appeared and are about 1/3 the size of the image:
Here the image has been scrolled almost to the limit of the horizontal scroll bar:
It's working as designed. That doesn't mean the design is right,
You should know that it's been this way for many major version releases.
That statement is not correct. I had never noticed problems with scrolling in CS4 or CS5. I often use the bars, when zoomed into an image, to jump to other parts of the image, particularly when comparing two versions of the same image for small differences in sharpness or contrast. In CS4, jumping never went past the image.
To prove that, I just reinstalled CS4, and voilà – the bars work correctly. When I jump, I never see grey, I only see image.
To prove it again, I just reinstalled CS5. Scroll bars work as they should.
But in CS6, when I jump to the extremities I often get a small part of the image and the rest of the window is a huge grey area. Since when do users want to see grey instead of image? Total hash of what is supposed to happen.
This is bug in CS6. It infected Phostoshop a few months ago. If it was designed to be that way, then it's a flawed design that should be changed.
Guy, R_Kelly is right.
I assure you on a PC this behavior is nothing new. Keep in mind on a PC we cannot disable the Application Frame as a Mac user can. With the application frame on overscrolling is possible.
If you enable the Application Frame in your older Photoshop you'll be able to see the same thing.
"Correct" points are yours, R Kelly.
The term "False mode" in what follows, is what I call the situation when the size bar goes haywire. To sum up for my future reference (in case I ever forget this):
For CS4-CS5 (Mac)
Application Frame is off by default.
Step 2 clearly shows there is a bug somewhere. If you work with tabs off and don't mess with Application Frame, there is no "False mode". But, as soon as you toggle Application Frame off and on, suddenly "False mode" appears.
For CS6 (Mac)
Application Frame is on by default.
Operation of CS6 seems to be as per CS4. From the users point of view, however, there is a big difference. By default you end up in "False mode" (because, by default, tabs are on and Application Frame is on).
