[Gimp-user] Unable to seek to tile location?
Hi all, I have to problems with the gimp at the moment. I'll put the second in another message as its a little more complicated to explain. I'm working with large images, 14764 by 2953 pixels. Yes they do need to be this big. The machine used for the work has 1GB of RAM and a 1.9GHz Athlon processor. The number of undo levels in the gimp is set to three. Tile cache size is set to 512MB. Typical projects have two or three layers at any one time. After a while working I get the following gimp error messages after I tell it to do something. This message repeats often many times. The message box has an OK check. "unable to seek to tile location on disk: 22 Message repeated ** times" The command I've given gets carried out and nothing appears obviously wrong with the image after this message comes up. Watching the resource usage by the gimp shows that memory usage is a little over 50% when this message starts to occur. Is this a ram problem, a hard disk one, or something else? I've been unable to find anything about this message in the documentation, or from a web search. Any idea what it means? The best way of preventing it?

[Gimp-user] Channel masks getting displaced from the layer.
Now for my second problem. I'm working with large images, 14764 by 2953 pixels. Yes they do need to be this big. The machine used for the work has 1GB of RAM and a 1.9GHz Athlon processor. The number of undo levels in the gimp is set to three. Tile cache size is set to 512MB. The images are landscapes stitched together from a number of digital photos. Typically on these the sky has been blown out and has no contrast. I therefore have been using a correctly exposed sky scene on another layer and need to make the original sky transparent, so there is the landscape on the top layer, with the new sky underneath. Selecting the old sky is relatively easy to do with the magic wand tool, but this doesn't work where the sky is seen through things like the branches of trees as the regions are not contiguous. I have therefore been copying selections around trees etc to a channel mask and using the threshold tool on the channel mask to have only pixels near 255 as white and everything else as black. This would then be converted to a selection and used to cut the sky out of the landscape layer. The problem I get is that on these very large images, when I copy the selection to the channel mask it gets displaced by about 30 pixels in the Y direction. After doing the thresholding and making the channel mask a selection, the selection will therefore be displaced from where it should be. I have tried making both original layers the same size as the canvas, in case this was the problem, but this has no effect. On smaller images (2560 x 1920pixels) this technique works perfectly, with no displacement of the channel mask. Is this a bug with the gimp, or am I doing something wrong?

This should be more than enough I reckon. The gimpswap.12359 file is currently 91.4MB. Is there something else that can artificially limit the size to which the swap can grow?

Re: [software] [Gimp-user] Photo stitch
Alf, There used to be a gimp plugin called panorama tools that was used to warp and stitch images together. This was designed for panoramic photography. It has evolved since into a standalone system and I'm not sure if the gimp plugin side of it still works. These tools are about the best and most versatile warping and stitching software available and they are free. Be warned though, the learning curve is steep. Getting them to work on Linux is a trial. People have written gui front ends for Windows and Mac that simplify their use a lot. There are also various tutorials available on the web. There is a useful mailing list too. See http://www.path.unimelb.edu.au/~dersch/ for the core panorama tools. A web search on panorama tools will bring up a lot of stuff. I use it extensively, and use the gimp to tidy up the resulting panoramic picture. Hope this helps.

This sounds like the phymodmedia plugin which can be obtained from http://uts.cc.utexas.edu/~foxx/phymod/ I recently added it to my installation of the gimp. Very good it is too.

[Gimp-user] Changing sky colour in Gimp 2.0.
I have a need to sometimes change the colour of a sky on a picture while leaving the clouds unchanged. In gimp 1.2 I do this by using the Decompose to Hue, Saturation and Value function, then taking the Saturation, inverting the black to white values and copying and pasting this to a layer mask on the original image. This set the blue saturated clear sky to varying degrees of transparency, depending on how deep the blue was, leaving the monochrome clouds unchanged. A layer could then be placed behind with the desired sky colour. I now have Gimp 2.0 installed, but have not found a way of getting the same results. There doesn't appear to be anything that can turn a picture into a grey scale based on colour saturation. Is there a way of doing this, or another way of changing just the sky colour? I'm currently using the vastly superior version 2.0 for everything, except this one task where I have to revert to 1.2.

Re: [Gimp-user] Changing sky colour in Gimp 2.0
Thanks Carol and Sven for the quick replies and spot on solutions for my problem. Jenny decompose has a new location; and everything else should work the same. decompose is now located at -->Filters -->Colors -->Decompose things have moved around some, it took me a while to get used to this. the changes make some sense, if you think about them. most of the changes are made between the Image menu and Layers Menu with a few things that are now located in Filters. gimp2 also has a new way to locate plug-ins. Xtns -->Plug-in Details. this should be helpful in finding the location of the old stuff in the new gimp. -- "On a planet of peril she dared to defy its evil rulers." ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
[Gimp-user] Changing sky colour.
I recently asked a question on the Decompose function and where it had gone to in the Gimp V2. This was promptly answered. I use this function as part of a process flow to change the blue colour in sky without affecting the clouds, or anything else. Jim Clark (of this list) was interested in the process that I use. Over the course of a number of emails we had enough screen shots and text to form a short tutorial. I've written it up and placed this on my site for your edification and delight. http://www.photojenic.co.uk/home-page/gimp-sky-colour.html Jenny -- "On a planet of peril she dared to defy its evil rulers." ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
