Re: [Gimp-user] how to invert greyscale values only... leaving colors alone

If so, I'd love some advice on the following task: I have an RGB image that is basically a black background with many colorful objects and white text. --- I'd like to invert the image so that it is a white background with black text but a simple invert inverts the colors in all the colored objects as well. Is there a technique or tool to invert any part of the image that is only a shade of grey? i.e. invert pixeils with a saturation of ~0 (if that is how you say it). I could imagine a filter that does a simple RGB invert for any pixel whose calculated RGB saturation value is below a set threshold. Does this type of tool/script exist? Simple. First create a duplicate of your layer. Then invert the colors on the lower layer and set the layer mode of the upper (unchanged) layer to Colors.

[Gimp-user] Loading/indexing fonts everytime GIMP starts
I've had this problem myself. I'm going to make a guess here - you automatically clear out your temp folder on reboot? Or have it on a ram-disk or something similar? Gimp stores it's font cache, by default, under the system temp folder. So, if the temp folder is cleared on reboot, fonts are re-indexed the next time GIMP starts. There's a fairly painless solution. Go to C:\Program Files\GIMP-2.0\etc\fonts and create a new file called conf.d (not local.conf, as the documentation would suggest). In that file, put the text: cachedir~/.gimp-2.6/fonts/cache/cachedir That will make GIMP store the font cache in C:\Users\user name\.gimp-2.6\fonts\cache, which to me is a much more sensible place to have it. Of course, you can choose a different path, if you prefer. Alex Hi, When I start up my GIMP in windows, it indexes the fonts every first time that I start after a reboot. I am using windows 7, is there anyway to tell gimp not to index the fonts ?

Hmm... I don't have that conf.d directory. Is there anything in it? I don't know enough about GIMP to explain that, someone else here might. You could edit the etc\fonts\fonts.conf to add the cachedir line above or instead of the existing cachedirWINDOWSTEMPDIR_FONTCONFIG_CACHE/cachedir line - although the documentation warns against modifying that file directly as it will be replaced when fontconfig is updated.

[Gimp-user] problem with genius 8x6 tablet and gimp
Hi. I've just replaced my old AceCad tablet with Genius 8x6 tablet. it works fine in ALL programs I checked except for GIMP . :( The problem is that the x-axis doens't react as it should. for example - if I user a brush tool - I get two cursors - one with a brush where the pen is and another where it actualy draws. I've googled for a few hours with no aparent solution. I'm using gimp 2.6.8 on windows XP home edition. To my best knowledge, the tablet driver is the latest and it seems to work fine. I also get preasure recognition both in gimp and in the tablet utility. Do you know of any solution about this frustrating situation ? Thanks, Ohad. -- Ohad N.

Funnily enough the tablet is reported to work with GIMP just fine on Linux. That is not too surprising. The Windows port of GTK+ does not get as much contributions as the X11/Linux backend. There are probably a lot more GIMP users on Windows than there are on Linux, but still there are almost no code contributions for the Windows specific parts of the code. It's the same for scanners and printing. Windows is a second-class citizen, simply because there is almost no contributions from Windows users.

Indeed frustrating .

Re: [Gimp-user] problem with genius 8x6 tablet and gimp
Hi everyone, This is my first post to the list and I'm still a GIMP newbie so I apologise in advance if I've violated a posting convention or sound particularly naive. Ohad: The problem is that the x-axis doens't react as it should. for example - if I user a brush tool - I get two cursors - one with a brush where the pen is and another where it actualy draws. If someone thinks it might help clarify the problem, I will be happy to upload a screen capture image of the problem. I've experienced my y-axis being uncontrollable (with the x axis mapping fine) but it was not accompanied by two cursors. Could you elaborate a bit more on what your specific problem is? Unfortunately I don't remember how I fixed my y-axis problem (sorry - was also on an Aiptek not Genius tablet) but a screen capture might be useful. I have also experienced a two-cursor situation but that was due to settings for a Wacom tablet. The tablet was configured within GIMP to map to within the program window, thus creating two cursors when the operating system additionally mapped it to the context of the entire desktop frame (I don't know what the proper terms are sorry). I rectified this by configuring the tablet in GIMP to the context of the desktop frame as well. Have you checked Preferences Input Devices Configure Extended Input Devices in case that's the reason?
