Re: [Gimp-user] Rotate a picture?
Hmm... the 45 degree angle part is simple enough, if that is what you really mean. However, when you start talking about a book at a 45 degree angle, it sounds maybe like what you want is to make it look as if it is being viewed from a 45 degree angle? ... not just rotated? ... with some sort of 3d look to it? If that is the case, you might want filtersmapmap object and map the thing to a box, then modify the settings so that you have a tall, thin box, standing on end with the picture on one face of it, sort of like a software box for a software ad. ...is that correct? ...something like this? http://tutorialblog.org/wp-content/uploads/2007/01/final1.jpg --- On Thu, 2/3/11, . pe...@aleksandrsolzhenitsyn.net wrote: From: . pe...@aleksandrsolzhenitsyn.net Subject: [Gimp-user] Rotate a picture?

First crop the image (easier to do at this step), then use the rotate tool. Rotate tool has options that allow you to specify the point that you rotate around, as well as the angle to rotate.

Branco, that may account for the increased size of a _rotated_ image, but Phil also increased the size simply during a re-save of an unchanged image. Phil, I suspect that when re-saving that image, you may wish to check the Advanced Settings popup to ensure that the PNG compression ratio is set to maximum at the time. WRT the rotated image, it wouldn't so much be anti- aliasing as that the rotation is unlikely to be precisely right-angled, so pixels along edges would be partially coloured, which would make the PNG compression process less efficient. If the image is text or something else essentially monochrome, Phil might try desaturating, then (regardless of desat) Auto/Stretch Contrast. This should minimise colour-gradient effects somewhat, so provide for more effective compression. If minute details are not so important, saving as JPeG will reduce the size massively without serious loss of visual quality. Loss of quality can be adjusted to a reasonable compromise level within the JPeG settings during SaveAs.

Then you used the selection tool to select the text within that text layer, and rotated the selected text. But you didn't rotate the layer itself, just the text. Then, when you deselected the text, the part of it that was outside the original boundaries was made transparent. What you do is to create the text, then immediately click on the rotate tool. This will automatically use the tool to rotate the layer itself, rather than to rotate a selected portion of the image within the layer. This is actually easier than the process you used, and you have now learned something interesting about GIMP's way of creating extra layers to manipulate.

[Gimp-user] rotate + crop - 1 action?
Dear GIMP people, When I rotate an image using GIMP a few degrees, to correct that I didn't hold my camera horizontal, the next step is to crop the rotated image such that it appears upright again. I realise that it must be possible to do the two actions all in one go, as the rotation angle fully determines the (max) area to which the picture can be cropped. Is this implemented somewhere in a script, or is this functionality available via other means?

[Gimp-user] rotate a pic
I want to rotate a pic about 20 degrees. I can easily do this in PhotoShop...but of course I end up with a larger pic the white triangles that square off the pic.

Resize the cancas before rotating the picture. Or after rotating the picture. Actually that's simpler since you can use the crop tool, select the size of rotated layer and crop/resize.

Re: [Gimp-user] rotate a pic
Hi, David Neary [EMAIL PROTECTED] writes: Use the rotate tool (part of the transform tool in 1.2.x) and set your rotation to 20 degrees. In the tool options make sure that Clip result is unchecked (which it is by default) and you will get a new, rotated layer with the extra bits being filled by transparency. However, the image doesn't get resized, only the active layer (or selection, or path). To resize the image you must use the crop tool in resize mode, or Image-Canvas size. Actually, we should probably add a way to rotate the whole image by arbitrary angle and have it expand just like a layer (unless Clip Result is checked). This could be an option in the Image-Rotate menu or it could be a new mode of the transform tools (next to Layer, Selection, Path). Or both.

Re: [Gimp-user] rotate image script-fu
would you can send me the script? I am very interested about using GIMP to make/process animations, so a script that gets all the imagens in a directory, and apply some kind of transformation in them would be very useful for me. And I am still a Script-fu beginner :) thank you, andrei Now *that* is a noble cause. ;-) I'm not really all that crazy about Scheme (Gimp's built-in scripting language), so I don't write with it. I really, really like Python, though, and there are Python bindings for the Gimp. You can download them at http://www.daa.com.au/~james/pygimp/ Use the documentation there, plus the PDB browser, to figure out everything you can do. In the meantime, here's a quick little script I whipped up to rotate a series of images in a directory. To avoid writing something that would be trivial to do with convert, I've put in a little twist... The first image is slightly rotated, the second a little bit more, and so on, until the last image, which goes to the user-specified rotation.

Am I missing something, or is GIMP really limited in the ability to rotate an image? I nice that it is only limited "right angle", 180, 360, etc. I have been saving temp images to disk and using ImageMagick's Display to do the rotating, then opening the edited file back into GIMP for further processing - and I am doing this with jpegs - which means that RGB data is changed each time I save the file. -- Rick Rosinski http://rickrosinski.com [EMAIL PROTECTED] ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
