[Gimp-user] Crop Tool Use Cases
A discussion on IRC about the new crop tool revealed that there are lots of different use cases for cropping. They're all important, and it's important to make sure there's a list of them so that the new crop tool will handle them. Here's a start. I hope people will jump in and fill in the details for the ones I'm unclear on (the constrain case and the zealous case) and add any other use cases I've missed. - Crop to selection. (Handled fine by Image-Crop Images. This might be the most common case, and the one a lot of GIMP newbies will use until they discover the others.) - Crop a small area of any size out of the middle of an image. (Handled fine by old and new crop tools.) - Crop an area of constrained aspect ratio, letting you move or resize the crop rectangle to choose the right area. (I don't do this very much, but people ask for it all the time, and maybe I'd do it if it were easier. Someone who needs/uses this should speak up with details on how it should work!) - Crop an area out of an image, retaining one or more existing edges. (Handled well by old crop tool; difficult in current CVS. Making the crop tool stop at the image edges, like the old crop tool did, would fix this.) - Crop a single layer image to the visible boundaries. (Handled by Autocrop, not by the crop tool.) - Crop multiple layers to the visible boundaries. (In 2.2 it was roundabout: select all, click in the image, click From Selection, then click Auto Shrink. In CVS there's currently no way to do it. I'd like to see the Autocrop menu item handle all visible layers (is there some reason it shouldn't?, or see a similar item, like Crop to Visible Layers, which does that.) - I assume there's a use case for Zealous Crop, but I'm not clear what it is. When I try it I usually end up with an image with a bunch of blank layers because anything with information has been cropped away. Can a Zealous Crop user speak up? Okay, crop users, tell me what I missed! ...Akkana ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

I've played with this in iPhoto - the implementation there lets you pick from a list of standard aspect ratios (2x3, 8x10), or a custom ratio, and then the crop is contrained to that ratio. The best use-case I can think of is for printing. If I know I want to print borderless on an 8.5x11 sheet of paper, I'd like to be able to crop to that aspect ratio directly, rather than letting the printer driver decide to crop it in some arbitrary way. ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

I use this quite a lot on photo's from my digital camera. I often want to crop the photo to the prettiest region of it, but I want to constrain the aspect ratio to make the result exactly fit my desktop, or to make it exactly fit the aspect ratio of my favorite online print shop. There are actually two use cases: - constrain to any custom aspect ratio. Possibly some preselections (3:4, 4:5, 9:16, 10:15, 11:15, ...) could be provided, but it should in any case be possible to specify any desired ratio. - keep the aspect ratio of the original (but I guess this is just a special case of the above) -- If I have been able to see further, it was only because I stood on the shoulders of giants. -- Isaac Newton Roel Schroeven ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
[Gimp-user] script fu and image file support?
I'm hoping someone can point me in the right direction. I want to write gimp support for an obscure file format. The format is relatively simple (simpler than TGA or BMP, for the most part), but does have a few variations where I would want to use multiple layers. I've written code in perl to convert to/from other image file formats, but maintaining that with all the variations is suboptimal because image features don't precisely overlap. I do not want to write a .c plugin, because portability is more important to me than speed. These images are relatively small (a few megabytes at most), and I'm hoping I can ignore all the load image an arbitrary tile at a time features of the GIMP. If not, I'll live with that, if only I could figure out how. If doing this from script fu kills performance, I can always advise people to save images in some other file format (such as .XCF) before manipulating them. I do NOT know much about scheme internals. I've been trying to study them, but I keep getting off on tangents that lead me elsewhere. I am comfortable with scheme, and think I know how to look up anything scheme-related but non-gimp-specific. Can someone point me at: * gimp 2.2 load/save support for some type of file written in script-fu? Or, * a concise reference work describing the data types I'd need to deal with and their fundamental support routines? Or, * a faq which is specific to this topic (script fu support for load/save)? Or, * anything else which you think would be specifically useful in this context? Or, if all else fails, I suppose I could try to dig up .XCF file format documentation and write conversion support to/from that format in perl. But I just know I'm going to hate myself, if I attempt that route. Thanks! (woc) ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
[Gimp-user] HP Laserjet 1100 print problems
Hi all, am having problems printing to HP Laserjet 1100 (printing grayscale) from Gimp. Printer shows in the printing dialog, but on the print command I get 1 page with %!PS-Adobe-3.0 %%Creator: Print plug-in V4.2 for GIMP/Gimp-Print 4.2.7 (15 Jul followed by many blank pages through the printer. The only way to stop it feeding paper is to cancel the print job. I have tried both PostScript Level1 and PostScript Level2 the only options available, with the same result. Have I neglected to install anything? Printer shows in the Printer name slot. Am using Ubuntu Linux 5.04. Printer is fine with Open Office, Gedit etc. Thanks in advance for any help, much appreciated.
