Re: [Gimp-user] How to create jpeg files compatible with a sony
The jpeg files that GIMP creates are perfectly valid. I think the basic problem is that you are trying to use a camera as a storage device, which is not its intended purpose. There are some cameras that, when you take a picture, create a digital watermark that the camera can use to tell if the file has been altered or corrupted. If the watermark does not match the data -- which is bound to happen after editing in GIMP, because GIMP does not know about watermarks -- then the camera may treat the file as invalid and refuse to display it. I should add that I'm going pretty far beyond my knowledge here. While I'm reasonably confident that this sort of digital watermarking does exist, I am only speculating that this accounts for your problems -- particularly with the photo-printing service.

One is to add layer effects onto the current GIMP architecture, which could be done, but in a somewhat hackish and ugly way. The other is to defer them until the arrival of the long-planned GEGL-based architecture, which will make layer effects and many other nice things easy and natural to implement. The decision has been to wait for GEGL. Whether this is the correct strategy can be debated, but it definitely doesn't mean that we don't care about layer effects.

Sven wrote: I don't know who's feeding you your information but that person is highly misinformed since there are no vector layers. If you want postscript or even pdf files using vectors instead of bitmaps, you are looking at the wrong application. GIMP is an image manipulation program for editing raster graphics. If you want to edit vectors, please use a vector editing application. The Gfig plugin now creates its own layers, and they are vector layers because if you run Gfig with the active layer being a Gfig layer, you can manipulate the objects there as vector objects. Dave Neary's GIMP 2.2 headlines mention this, with perhaps a bit more enthusiasm than is entirely justified -- this is presumably the source of the misinformation. In any case, the capabilities of Gfig are quite primitive in comparison with well-developed vector graphics programs such as Sodipodi or Inkscape -- and strictly speaking, the functionality does not come from GIMP itself but rather from the plugin. The rest of what you wrote I think is quite correct. It may be interesting to note that it would theoretically be possible to modify programs such as Inkscape or Sodipodi so that they would be capable of running as GIMP plugins, creating their own special layers and storing their data as layer attachments (i.e., parasites in GIMP terminology), in the same way that Gfig now does.

Re: [Gimp-user] dpi from 75 - 300 ??
Geoffrey wrote: So here's a question which will demonstrate my ignorance. I've got some digital photos I took that, when opened with GIMP are identified as being 75dpi x72dpi. I need images that are 300 dpi, so is it possible to convert the 75dpi image to 300 dpi?? I selected to scale the image and happened to notice that I can make this change at this point. Is this doing what I'm expecting? That is a question that only a mind reader can answer. (Sorry :-)) Here's the thing: a resolution in dpi is not a property of the image per se, it's a property of the way the image is displayed, on the screen or on paper. When you see a resolution of 72x72 dpi for an image, what those numbers represent is somebody's judgement that the image will look good when displayed with 72 pixels per inch; and usually this means look good when displayed on a monitor, because nothing looks very good when it is printed at 72 dots per inch. Now suppose you have a 300 x 300 pixel image, with a nominal resolution of 72 dpi, and suppose you want to convert it to 300 dpi for printing. There are two approaches you could take. (Actually more, but let's keep it simple for the moment.) (1) You caould say, okay, 300 pixels is about 4 inches at 72 dpi. I want my print to have the same size. So, I will scale the image to 1200 x 1200 pixels, and set the resolution to 300 dpi. (2) You could say, okay, I don't want to make the image look blurry by scaling up the number of pixels, so I will simply set the resolution to 300 dpi without changing the pixel dimensions, thereby getting a print about 1 inch across. Both of these are legitimate choices, and so are many others. The best way to do it depends on your image and your printer. What makes it complicated is the fact that printer dots have much poorer color resolution than monitor dots. On most modern systems, a monitor dot encodes 24 bits of color information. On a typical high-quality printer, a single dot encodes about 6 bits of color information. Thus, simply changing the resolution so that a single monitor dot becomes a single printer dot is usually not the best thing to do.

[Gimp-user] Re: dynamic text glow, what happened to them?
Dynamic text is no longer needed, because the things it did are now done by the regular text tool (and done a lot better, too!). I don't know about the glow filter, but there are indeed some filters that have not yet been ported from Gimp 1.2 to Gimp 2.0.

Re: [Gimp-user] can't install GTK+ on Debian 3.0 r1
Well, the right place to ask is [EMAIL PROTECTED] -- but a wild guess is that it might help to run ldconfig, if you haven't done so.

Re: [Gimp-user] gradient-blur
For what it's worth, I went ahead and implemented a true variable blur filter, by modifying the blur plug-in code from 2.0. I'll put the code in the plug-in registry after a little bug-fixing, but anyway, I put together a comparison of what you get with variable blurring versus what you get with variable blending of blurred and sharp images -- you can see it at: http://gug.sunsite.dk/pictures/1080149573.png Please note that I am not saying that one is better than the other, just that they are different.

Of course it's not the same but it should look reasonably similar. On Fri, 19 Mar 2004, Jakub Steiner wrote: Just create an appropriate selection for the blur filter. The fastest method in this case would be toggling the quickmask, creating the gradient, toggling back and applying the blur filter. What is the best technique? What you suggest or the one that follows? Are there any problems with these two ways, compared with the mod of the blur filter way? Neither of these techniques work, as you will see if you try to apply them. When you mix a blurred image with a sharp image, the result does not look like a less-blurred image, it looks like a sharp image whose contrast has been reduced.

Re: [Gimp-user] gradient-blur
Actually the reality is that Gimp, with the standard plug-ins, does not have the ability to do this, although there are ways to fake something that looks sort of like it. The easiest way to get it would be to modify the blur filter (found in randomize.c in the plug-ins directory) so that the probability values are derived from a map-image rather than constant. This would really be a valuable thing to have.
