Stephane Delcroix, the maintainer of F-spot, has sent me this link to his blog. There he describes the GdkPixbuf loader for XCF he wrote.This allows a lot of Gnome programs to read XCF files. He had to do this under “Clean Room” conditions because GIMP is GPL licensed and he had to release under LGPL. So he wasn’t allowed to look into the source of GIMP and had to use some documentation and the old fashioned hexdump and brain combination.
Full XCF suppurt for F-Spot will follow. Now you can see and open XCF files in GIMP, but sending a JPEG to GIMP and getting a XCF back is in the pipeline. Stephane mentioned a “perhaps” date, but I’ll translate that into “soon” here. 😉 I’ll keep you updated.
Then I begin to work at an image of a ship coming down the river Weser on a foggy morning. The image is mostly gray and very low in contrast. As this was shot in RAW, it is possible to get something usuable out of it. You get a lecture about the difference of 256 steps between black and white in JPEG and why the 4096 steps in RAW are better.
(I assume there would be more detail in an JPEG out of the camera because it does some postprocessing…)
I show how to access the menues of the GIMP in three different ways, how to analyze an image with the histogram tool and the colour picker, how to rotate an image just a little bit and how to crop it using the Rule of Thirds (not a LAW – but a nice rule of thumb) to get an aesthetic result. And I nearly forgot to save the image in GIMP’s native image format – XCF.
Please let me know what you think about the show. Too slow? Too fast? Too much ramblings? Or too much information? Even if you like everything – write a comment or drop me a mail at firstname.lastname@example.org
