Numeric X/Y values in Curves dialogs
Last modified: 2003-12-13 17:24:22 UTC
I'd like to see an input widgets in Curves dialog for X/Y values. It could be usefull to hand made some mathematically generated curves for some special tasks (simple example is color balancing, ie. setting white balance). Currently there is no special color picker for setting white balance (I hope it will be soon). Another task is aplying HDR curves, log curves etc. Regards Piotr Legiecki
Isn't it a lot easier and way more convenient to use your preferred text editor and create a GIMP curves file, then load it into the Curves dialog?
Well, I have tried this aproach but the Excel's sheets I use produces somewhat different numbers (in different format) than the ones gimp expects. So it was really annoying to translate them online (in my head). It is also much faster to write a few numbers than generate all the file in vim and load this to gimp. Anyway gimp reads Curves in his own format and AIM or other scripts/sheets produces photoshop files rather (*.amp files). And plugin which reads amp files is ugly/broken.
I am pretty sure that a Perl script to convert from Excel-generated CSV files to GIMP's curves files would be a one-liner. A script that converts from amp files would probably not be much longer. In my opinion we shouldn't clutter the dialog with something that can more easily be achieved outside the GIMP.
If you could provide enough info about the .amp file format, we could even add support for reading this format directly. Regarding the numerical input entries, isn't it actually easier to use the mouse and the displayed coordinates instead of entering the numbers by hand? After all you need to to use the mouse to select the point you want to edit anyway.
Changes at the request of Dave Neary on the developer mailing list. I am changing many of the bugzilla reports that have not specified a target milestone to Future milestone. Hope that is acceptable.
Unfortunately noone provided information about the .amp file format. Otherwise we would probably have added support for it in the meantime.
Here you are the Vbasic code from Excel spreadsheet for saving AMP files: http://tme.szczecin.pl/~jacek/temp/AMP.txt Cordially -Jack Zagaja,
Should this report be renamed to "Support the .amp format for curves" then?
Well, about the amp support. It would be nice to read it directly from Curves dialog (not by plugin), but I would like not to make Curves dialog too complicated . The amp files should be recognised automatically and read (and I think converted somehow to gimp format on the fly). So, no special widgets in Curves dialog for this task please. It is not a high priority task, so if it is difficult, you may move it to the plugins area. Regards Piotr L.
