There are several situations where you may wonder why some tools do not work. Here are some things to check:

• Many tools (for instance, the paint tools) only apply to the "selection" and if you have a selection the effect of these tools is restricted to the selected pixels. In some cases a very small selection is created by mistake, so painting in most parts of the image does nothing. This is easy to check: in the "Select" menu, "Select/All" and Select/None" are both available when there is a selection on part of the image. Click "Select/None" to remove the unwanted selection.
  
• Tools apply to the selected layer, so check in the Layers list (Ctrl-L) that the right layer is selected (blue highlight). Tools also have no effect outside of the selected layer boundaries if this layer is smaller than the canvas (you can enlarge it with "Layer/Layer to image size")
  
• A corollary to the two items above, if the selection and the active layer have no common pixels, nothings happens.
  
• Locked pixels cannot be altered. Check the pixel-lock and alpha-lock status of your layer at the top of the Layer list.
  
• Many filters only work on RGB images, and the corresponding menus will be disabled/grayed if you have a grayscale or indexed image. The type of the image is next to its name in the title bar, and can also be checked in the "Image/Mode" menu.
  
• The tools in the "Colors" menu do not work on indexed images (GIF images are color-indexed), but nothing makes that obvious, the tools just seem broken in that case. 
  
• If you have a "floating selection" ("Edit/paste", or after using transform tools with a selection active) many operations are forbidden until this floating selection is either "anchored" or transformed into a plain layer. The floating selection is visible in the Layers list.
  
• Paint tools may be put in a "paint mode" that has little effect on the pixels you are using. Check that that the paint mode is "Normal" unless you really want it otherwise.
  
• Check the brush you are using. If set to the 'clipboard', the clipboard contents may have changed. Try with another brush.
  
• Check the tool opacity
  
• Check the layer opacity
  
• On the Paintbrush, check the "Force" setting
  
• Check the "Dynamics" settings (set to "Dynamics off" until you know better)
  

Hallo,

Hi All,

I have recently been undergoing Logo design and have now completed my logo :

I am now trying to convert the image into Vector format with Inkscape as I have been reading in other posts however the text is going blocky and not crisp colours and outlines as it is in Gimp.

Is there a certain way I should be doing things in Gimp before this or can I do this any way inside of Gimp?

Thanks for any help
 
see attached the logo I am trying to convert. Thanks again!

It seems they forgot to renew the name... *makes mental note to check how long before gimp-forum.net goes the same way*

I have several large (10800x7200) 1 bit images that have many single black pixels scattered all over the images. What is the easiest way to select ONLY these single black pixels and nothing else?

Thanks Fred

Hello,

During the above window, the networking team will be performing hardware upgrades on the AMS3 network. This work is to increase capacity and throughput for the AMS3 DC.

Expected Impact:
We expect the impact of this change to be minimal; however, you may experience short periods of latency lasting 1 to 2 minutes while traffic is rerouted.

Hello
My layers toolbox is frozen... All the buttons are greyed and I can't select a layer. I was just trying to move the current layer down the list but nothing happened.
I read in another post that I should have "auto follow active image" selected, which I have tried, but nothing has changed.
I've been using gimp for a while, and can find solutions to most problems in various forums, but this one has stumped me and I'm up against a deadline! Any help gratefully received.
Thanks

I want to ask if there is a plugin, like pdb.gimp_text_layer_set_markup, but instead of markup, this to use about functions/modules of TeX. For example: if want to put a footnote in a text_layer, to call this plugin, instead of make a new text-layer with a separating line and a -usually- smaller size font.


If there is not something like that, I want to ask if you think is useful a trial of developing something like that.
As for me, I 'd be very eager to contribute.

I'm a  GIMP newbie who wants to print the online help contents.

(1) is there an EZ way ?
(2) if not, there are books avail for sale but the latest one is for 2.8. When will 2.9 be avail ?

Thanx.
