Re: Unusual Image Rotation Request
From the AIC documentation: rotate() Description The rotate() method rotates an image by an arbitrary angle. Any portion of the rotated image which exposes the background is set to the current background color. Syntax rotate(angle, resizeImage) Thank you, sounds perfect.

Re: Unusual Image Rotation Request
adding arbitrary rotation angles would be pretty trvial to your choice of image manipulators, as long as you can get the source. I wouldn't say so: rotation by an angle being a multiple of 90º is pretty trivial, because the transformation can be reduced to some symetry. All pixels are preserved, and no new pixel has to be created. Any angle rotation is quite a different and more complex algorithm, this is why most tools provide only 90º rotations. -- ___ REUSE CODE!

Re: Unusual Image Rotation Request
I'm not saying build your own pixel rewriter. I'm saying that most tools only expose multiples of 90 because that's good enough 99.999% of the time. Pretty much any tool is going to be build on top of a graphics library of some sort, and I've yet to see such a library that doesn't support arbitrary rotation angles. So it'd just be a matter of making the CFC or CF/CFX tag leverage that capability. For example, Alagad Image Component uses the Java 2D libraries, which certainly support arbitrary rotation, though I don't know if AIC exposes it. If it's not there, adding it would be trivial. I suspect that many (most?) other tools work in similar fashion. cheers, barneyb On 10/30/05, Claude Schneegans [EMAIL PROTECTED] wrote: adding arbitrary rotation angles would be pretty trvial to your choice of image manipulators, as long as you can get the source.

Unusual Image Rotation Request
I see that many of the image manipulation tools can rotate images 90, 180 degrees etc. I am looking to rotate an image an arbitrary amount, perhaps 35 or 68 degrees for example. This would give me a larger rectangular image than the one that I started off from, with the corners of rotated image defining the boundaries. Alternatively. Does anyone have any suggestion how I might achieve this 'angled image' on a web page without manipulating the image file?

Re: Unusual Image Rotation Request
I'd wager that adding arbitrary rotation angles would be pretty trvial to your choice of image manipulators, as long as you can get the source. Even if you can't get the source, a wrapper/extension should be able to package the functionality pretty easily. The trick is that you'll have to explicitly do the resize before you do the rotation (i.e. do some math to figure out the new dimensions, and call resize), but that's simple stuff. cheers, barneyb On 10/28/05, Peter Shaw [EMAIL PROTECTED] wrote: I see that many of the image manipulation tools can rotate images 90, 180 degrees etc. I am looking to rotate an image an arbitrary amount, perhaps 35 or 68 degrees for example.
