Jagged Edges From Rotating Image...

1080 views15 repliesLast post: 6/26/2005
As I said above, I was getting a diiferent size image
when I was rotating an image of a statue taken with the
camera in vertical position. I can correct the situation by choosing Pixel/Aspect Ratio/D1/DV NTSC Widescreen (1.2) from the Image menu. However, I now have slightly jagged edges for the statue. How can I smoothen up those edges? Is there some kind of anitaliasing that I can apply? I know that antialiasing is available for various tools. But how can it be used on a given image without using such tools (like lasso, etc.)?
Thanks!

Is your monitor an LCD? If so you are probably not using the native resolution, which is causing the appearance of jaded lines - check your monitors manual for what the native resolution should be. Are you viewing the image at 100% resolution?

My monitor is set at 1024x768.
Thanks!

Is it a widescreen? Is it an LCD? What resolution do you have the monitor set at?

My monitor is set at 1024x768.

But is it a normal 3:4 ratio monitor? The jagged edges are almost certainly not real. They are caused by a wrong setting of your monitor, so you shouldn't try to 'fix' them but 'fix' that setting.

As I said above,

Um, if I look above this post on my monitor, I'm looking into the future relative to this post.

that I can apply? I know that antialiasing is available for various tools. But how can it be used on a given image without using such tools (like lasso, etc.)?

The default interpolation method is set in Preferences->General.

Yes, but is it a 4:3 ratio monitor or is it a widescreen?

1024 x 768 = 4/3 ratio.

Not an answer to the question....

Also what size is the monitor? For instance for most non-widescreen 17" and 19" LCD monitors have a native resolution of 1280x1024, but many people set them at different resolutions - which can cause problems. 1024x768 is NOT the same resolution (1.333 vs. 1.25), so if your native resolution is 1280x1024 you will be looking at distorted images. It took me a week of nagging, and demonstrating with scanned images to convince someone at work that they were looking at elongated people in their scans - remarkably a lot of people are insensitive to such distortions - hence the number of people who willingly watch a 4x3 TV image stretched on a widescreen TV

That ain't the point. Use View Actual Pixels.

No, it wasn't a full answer. I guess I was just annoyed at hecate's replying off a post by John E., repetitously and needlessly.

Yes, your statements are all correct. But I can't imagine a wide screen even offering a setting of 4:3 or 5:4 when the true ratio would be more like 2:1. But, I don't have access to one right now, so I don't know. It took me a week of

Yes, I hate when that happens! I also hate it when a broadcaster says its showing in HD, and then put out a crumby quality 720p picture- probably "studio enhanced NTSC" or something....

Back to the OP:

Maria- What choices do you have for setting monitor resolution? --

IF the pixels are square!

No, that's the resolution she's using. It doesn't describe the size of the screen which may be in a different ratio.

It wasn't any answer, except that of showing that you don't understand the difference between screen size and screen resolution.

If someone wishes to comment, I have the right to reply. If you don't like that you should go somewhere where your feelings are better protected.

Of course, as I said later and which you also replied to.

But there's no wide screen involved, and your question misses the mark.

ER, no actually. Caitlin pointed it to you before you said anything.

How do you know as she hasn't stated to anyone who's asked whether she's using a widescreen or not. Mindreading?
