Re: [Gimp-user] Question about saving jpeg images
gimp uses 85% quality as a default one for a jpeg image, it might be that your camera is using a 100% quality by default, try changing this setting (use the Save As option). the DPI is just a way of telling other application how big (in dimensions, not the filesize) the image really should be (after printing for example) On 7/19/07, Jeffery Small [EMAIL PROTECTED] wrote: I am using the 2.3.18 development version of gimp on a SPARC Solaris system, but I also see this with the 2.2.15 version as well. I have a 4MB jpeg file created with my Minolta 7D camera. I load it into Gimp and then immediately save it. The resulting file is now only 482kB in size! When I use exiftool to examine the exif data, I see the following unexpected changes: Original VersionSaved Version - - File Size: 4 MB482kB X Resolution: 72 300 Y Resolution: 72 300 Minolta Image Size: Large Medium Focus Mode: Manual Single-Shot AF ISO Setting:Auto800 Free Mem. Card Images: 300 1 Rotation: Horizontal (normal) Unknown (0) Image Number: 3 4 Image Number 2: 55233 The saved version also reports: Warning : [minor] Possibly incorrect maker notes offsets (fix by -94?) It appears that the development version of gimp is messing up the exif header in a number of ways. But why is the file being truncated to such a degree? Is there something I have set incorrectly that is causing this? Is there a preference setting for a default level of jpeg compression? In both cases the image size is being reported as 3008x2000 but note the difference in the DPI resolution. I feel as though I must be missing something obvious. Thanks for any pointers you can offer.

Re: [Gimp-user] GIMP and tilt sensitivity
Hi, [EMAIL PROTECTED] (2007-07-22 at 1801.32 -0400): Thank you very much for your examples, they also helped me understand a bit more the Save as GIH dialogue. One of the things that strikes me as illogical was that you start the ranks from the bottom and go to the top as you add more ranks?... It seemed more logical to me to have the first governing rank on top, while the second is underneath it, etc. If you don't mind explaining the logic, it would be great and might teach me a thing or two about GIMP and this concept. Origin of coords does not need common sense, just that the rules are known and not ignored. Someone decides 0,0 is somewhere, and +X goes this way and +Y this other. That applies both to maths and to this. :] Sadly known is not 100% in GIH-land (I remember Gimp 1.2 dialog had controls to the side and even allowed 5 dimensions, even if only 4 controls were provided... what was the 5th?), at best you have to go with empiric conclusions. So, taking your brush pipe-brush-pressure-angle-and-tilts.gih, I read the first rank for x-tilt, composed of 3 cells. Next rank, y-tilt, created from 3 cells as well - so far, that's a 9 cell matrix with the numbers 1 through 9, printed according to the X/Y tilt. Then you have an angular brush with two ranks (the black and red colored numbers governing the angle of your stroke, somehow the black only appears from degree 0 (upwards) to 90 (right), from 90 to 359 the red takes over? Shouldn't it be black from degrees 0 to 179 and red from 180 to 359?) and the last rank, pressure, uses black and red colors for a light pressure and green and blue for harder pressure, alternating colors as per the angle of your brush. I learnt that looking inside the GIH files was a sure way to get a headache. I always looked at XCF versions, and considered GIH a nasty manual step required to get brushes working, instead of having the XCF as single file that had to be created and tweaked. Or even better, having that and run-time controls to change the mappings (what goes with pressure, etc), so not saving at all except to change images or default mappings. The 3D angle-and-tilts brush works, giving ~90 deg to each of the four layers. But yes, I checked the 4D pressure-angle-and-tilts brush with mouse, and it strangely gives a 90-270 instead of 180-180. I thought (or so my memory says I did), that it would select one of two groups by angle (KR or GB), and then select the exact layer by pressure (if it got to KR, K or R). I am unable to test pressure (or tilt), but if you say it selects two colours for high and the other two for low, that part seems to match what I thought. When the dialog was to the side, I read it this way, for 4D: Select SelectSelect Select group of - one layer - cells in - cell in layers from groupY axis X axis The example brush has the following: Pressure - Angle - Y tilt - X tilt So the path would be, with mouse (fixed pressure, fixed 0 tilt): KR GB- K R- 2 5 8- 5 - Black or red 5s Mouse 0-90 0-deg 0-deg pressureortilttilt says90-360 1st (?) always Maybe there is a bug, or I set something wrong in the save dialog or some hidden rule escaped my experiments (maybe there is no layers in groups after all, go figure). P.S. I'm explaining these things back to you just to make sure I understood things right, please don't feel offended if I state the obvious :) But your example is much appreciated, it proved the options work as expected (except that weird angular decision) and also gave me an insight the manual was not able to provide. No problem, I remember the issue is far from documented, it seems barely anybody knows how things work or worse, how it should work, so the topic quickly gets discarded. Experimenting without going into the deeper levels is enough for me, even if not being 100% sure the things are correct. This is the third time, at least, years ago first, the IRC session second, and some parts still unclear. Sadly all the manual steps (including for single image brushes) makes the brush system really tedious and clunky, so I understand that as things get more complex they get less use and less understanding. Good luck trying to figure any misconceptions or missing details. See the issue with 90+270 deg instead of 180+180, and I would add why you can control the cells up to 1000 or why playing with different buttons makes other values change (cell size - number of cells and count in first rank, but not other ranks). Best would be figuring how it was planned to be. GSR ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
