[Gimp-user] Gimp rebuilding user files?
I started up GIMP today (2.6.11 on Win 7 x64), and got an extended pause and the startup windows showed "reading patterns" as best I remember. I do recall in the past fooling around some trying to add a pattern file, but can't remember exactly what I had done. At any rate after an extended period GIMP started, but configured a bit differently. Looking around my system I see that the C:\Users\\.gimp-2.6\ folder hierarchy seems to have been completely rebuilt. Per the help that appears to be normal if local GIMP settings are missing or damaged. But doing some mucking around, I found another copy from earlier in C:\Users\\Appdata\Local\.gimp=2.6\ I did a compare of the two folder hierarchies, and did find a reference to pattern-path and pattern-path-writable in the older gimprc. So I backed up the new .gimp-2.6 and copied over the older one to C:\Users\\, except I kept the new gimprc, and now GIMP is loading OK (AFAICT) with my original .gimp=2.6. So I guess I'm wondering what happened, and where is .gimp-2.6 supposed to be located in a Win 7 x64 system? scott s. . ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] GIMP crashing on memory allocation (WinXP)
I'm trying to edit some large tiffs (620 Mb) and while slow it was going OK. Then suddenly (nothing changed AFAIK) I start getting errors GLib-ERROR* gmem.c:130 failed to allocate 16384 bytes aborting. This was initially on GIMP 2.4.7 but I bit the bullet and installed 2.6.8 to see if that changed anything (it didn't). I take it that the faulting module is libglib.dll which seems to have a version of 2.16.37 (I believe I had an older GTK+ but the GIMP 2.6 windows installer updated it.) This is on the Windows binary distribution. I am running on Win XP sp3 32 bit (x86) with 3 gb switch and USERVA switch set to 2540.. Looking at my system when the crash occurs I see my physical memory (2gb) is maxed out and also GIMP VM is 2 gb. I guess one question is does the windows build of GIMP compile with LargeAddressSpcaeAware set, though I suspect even if that was set in the binary it would still max out. That doesn't explain why it seemed to be working and just now I have problems. I tried playing with the tile cache size option, but that just seems to change how fast the error occurs. It seems that the tiff file open plugin is completing and GIMP is either starting to render or at times render is complete and I try to use a selection tool and then the crash occurs. scott s. . ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

[Gimp-user] Saving individual layers
I've been using the Microsoft Office scanning software. It has the capability of saving scans in tiff format. There must be some provision in tiff that allows multiple images (pages) to be saved in a single tiff format file. Gimp 2.4 (Win XP) tiff reader understands this format, opens the file and asks if it should open each page as image or as layers. Opening as layers allows single operations to apply on all pages, making work easier. The problem is there doesn't seem to be any way to print without flattening (all you get is the top layer of course) or to save the result, keeping the layers, in some format that another program can read. What I would like is something that could convert layers to images at least. scott s. . ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

In earlier versions it would produce a huge stack of error message windows when loading, complaining about unknown tags, but now in ver 2.2.15 it just gives 3 errors per GeoTiff which is manageable. I load my GeoTiffs in GIS software first to save the geo data before editing in GIMP, so I can then reload it using the data and have my GIS restore the GeoTiff tags. scott s. . ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

What you are suggesting would work, but the "best" solution would be to use GIS software for this task. There are a number of open source and freeware GIS tools, the biggest problem is that in general they are not designed to directly access the Google data. That can be worked around, but probably is more work than you are interested in, unless you expect to do more mapping applications. When you say you want to "download the photographs" do you mean using the Google map api, or taking screenshots of a Google Earth view? Or are you using one of the pay versions of GE (I think these offer more options, but haven't investigated). scott s. . ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

The advantage to editing the channel mask is that you can set a color for the mask, which makes it easier to see just what you are doing.

[Gimp-user] Editing the alpha channel
I seem to be missing a basic concept. If I open an image with alpha channel, I can't find any way to edit the alpha channel. I end up using other software to save the alpha as a grayscale and editing that. That requires converting my 24 bit image to grayscale too so I can load the alpha as a layer for editing. What I want is to keep the 24 bit rgb image and edit the alpha as an 8 bit layer. FWIW, I generally use 32 bit targa format for editing image with alpha., because I don't have any filter for directX compressed formats (DXT1, DXT3). scott s. . ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

Then it is not 400 or 100 DPI, but (rounding to 1 inch = 2.5 cm) a 4 inch print, so you have printed 100 pixels to 4 inches and 200 to 4 inches too, so that was 25 and 50 DPI. Maybe you are confused with the printer's DPI (300, 720, 1440...) but those are not pixels, but ink dots. The print system has to convert the file/screen pixels (think about them like squares or rectangles with different levels of intensity) to ink dots which are on or off (one level of intensity, so the printer creates patterns of dots to simulate the intensity levels when looked from "far away"). I have been trying to understand this better myself. I couldn't find any good help on it. My goal was to determine the maximum size image in pixels that would print exactly on a letter-size paper with no scaling. I built a resolution test image and found that the highest resolution that I could see a 1 pixel line on my printer was about 150 pixel/inch. This is on windows xp. I see that in at least some file formats, the resolution setting is saved in the metadata as dpi. But when I print the image using different applications, I get different results. The apps seem to use or package the data differently for the driver. For example, one app has options in the print dialog for "fit pixels" "fit resolution" and "fit to page". I haven't figured out yet exactly what this does (other than fit to page obviously scales the data up or down as required. My printer also has a poster mode (2x2, 3x3,4x4). As best I can determine all this does is first scale the image to a single page in the app and then the printer just zooms it (I don't know if it does any sort ot interpolation but I doubt it). scott s. . ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
