two finger image rotate: how to get straight again

[kkamin]

I want to use the 2-finger, track pad rotation feature on my mac lap top while I work in Photoshop, but is there a way to get the image back to perfectly straight up and down?

Thanks!

How about Ctrl-Z (undo) ? Just kidding, as I thing you're looking for something more robust.

There are plenty (as in hundreds of thousands) of fee actions on the web for such stuff. Or you could write your own. But, the others a very reliable and supported quite well. In fact our very own Plugsnpixels has a website that does just that.... log good plug-ins and actions, offer them to you at substantial discounts. Check him out at Plugsandpixels.

Thanks for the info! I super appreciate it.

On a side note, from one human to another, I would humbly suggest you drop the attitude if you can.

I also didn't know this and did not sense an attitude. Maybe it's in the eye of the beholder. Hope my attitude hasn't leaked into this!

Again, I appreciate the info. It will be revolutionary in my retouching--I'm not as good drawing with my Wacom in certain directions, so to be able to rotate the canvas in a non destructive way and exploit my drawing tendencies in order to retouch will be awesome. If Namphoto had not responded, I probably would have avoided using this aspect of the Mac touch pad since I would not feel confident in getting the canvas to align correctly.

Perhaps I shouldn't be calling "attitude" on the person that just helped me in a big way. But the simple sentence of "why does nobody know this." is an obvious put down to the community. He/she isn't asking, why doesn't anybody respond, but why don't you know how to do this? It is quite condescending when you think about it. Maybe others know this person well and can gather a different interpretation from the quip. But imagine you are trying to fix a leaky faucet or bake a cake and someone walks up to you and says "why don't you know this?". It is basically saying that you should know this and that you are inadequate to some degree.

You might be thinking that I am reading into this too much or I am misinterpreting the message. But in all honesty I think I am just addressing a very cocky young person with an ego to feed.

(...) But in all honesty I think I am just addressing a very cocky young person with an ego to feed.

Maybe is because I have a big ego myself.
But sometimes is difficult to understand how can someone "not know" "don't understand" something. It happens to me all the time.

Does it look pink/purple? Add yellow or decrease blue with a curve, duh!!

And ppl look at me like : wut?

And I have to show them and it's really hard for someone who already has the knowledge and sees something as really simple, to get the other person not knowing this.

I dunno.... I don't think that makes one inherently "bad"

If only God had created us all with "Mind Meld",
all of this bickering and fighting would go away.
Everyone would know everything but we would
also realize how insecure everyone is.

Alas, no mind meld yet. So we have to trudge along
and learn things as we go. Those that find out first
or know something we don't, even if they just learned
it the day before, have the all mighty right to give it
to us anyway they want, even with a dalop of attitude.

Now, we need to hear from namphoto, to which we
should all be grateful for taking the time and effort to
share an answer to a question. So, namphoto, please
tell us what was going through your mind when you posted
your answer?

First off, I don't think they are "bad". Just a bit condescending.

The fact people are discussing this and I keep discussing this by virtue, is blowing the matter up larger than it is. But I am still bothered by it nonetheless. Perhaps I am thin skinned, but I find many forums to be lacking in manners and respect. I know the internet gives everyone a certain level of anonymity and with that can come less civility. But still, come on. I think the mission of the forum is to build community and support artistic or technical growth.

Imagine I ended every thread I responded to with "Why doesn't anyone know this." What kind of impression would I make?

I don't know. I try to go into most communications with a respect towards the person or people and would like it to be a pleasant interaction. If it is a sharing of knowledge or opinion, I think it is rarely beneficial to put down the listeners. Maybe this is a radical concept.

I guess if you want to live life like jerk. Imagine have a teacher or professor give a lecture with the attitude that the class is retarded for not knowing the lecture beforehand. I don't think Namphoto worked for Macintosh and invented the ESC key orientation revert, and at some point he didn't know this either like many of us.

Namphoto, look what you have started!

Back to the topic and little off to the side ..... I'm a little curious about this.

Correct me if I'm wrong, but if you're constantly rotating an image, wouldn't the image degrade unless you were rotating on precise 90 degree angles?

It's been a long time since I've done any programming, especially 2D texture rotation; but I'm pretty sure I remember you always need to calculate the rotation of an image from the original source; because if you keep arbitrarily rotating an image and rotating it again, it will eventually degrade ..... so, rotating an image and straightening it constantly, you'd end up with less detail in the image.

Or, am I way off base .....

[Der_W]

That would be true, if you were really rotating the image (easiest example: rotate the image 45°. Pixels are squares, 45° would need half pixels, which don't exist -> interpolation).
But since PS CS4 it is possible (with OpenGL) to rotate the view itself, so no pixels are harmed :-).
