I find this extremely difficult to believe. I think it's more likely something about the image that causes gimp_by_color_select to behave in a way you don't expect. For example, if your huge image is indexed, that might cause this effect you mention; the threshold selection options (eg, in 'magic wand' and 'select by color' tools) do work in indexed mode, but the result often isn't meaningful (since the threshold is applied to the colormap indices of the pixels, rather than the actual colors they point to.) Does toggling 'sample merged' effect the result? I have done my tests with: Antialiasing ON (does nothing anyway, AFAIK) Feather OFF Select transparent areas ON Sample Merged OFF Select by: COMPOSITE (if you had been using the wrong value here, it could have tripped you up too.) On a 8000x6000 PNG image (on an AMD Duron, Ubuntu 6.06, GIMP [latest from SVN] ), I have tried to reproduce your problem with both an indexed and a grey image, and neither display the behaviour you mention. The select menu always shows 'None' as disabled and 'All' as normal after the image is opened, indicating that the selection is currently empty (None). In fact, the menus do not indicate whether all pixels are selected -- you can see that the 'All' menu entry is never disabled, so even when the selection already covers everything, you can still Select->All. If you want to check the state of the selection, there is a 'Selection Editor' dockable you can access which provides a clear display of the current selection mask. Lastly, it's possible that the file plugin for whatever format your image is in is interpreting some data wrongly and so mistakenly resetting the selection mask to this confusing state. What format is your input file(s)? _______________________________________________ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
