Gimp Basics: Color dropper, Magnify, Measure, Move
If you wish to match or identify a color in a photo use the color dropper. It looks just like an old fashioned eye dropper. Open your image in Gimp, select the color dropper and double click on the color you wish to id. The ‘Color Picker’ box will pop up with the color shown in a swatch and your Red/Green/Blue pixel values, %, and Hex code for that color will be shown. It will also change your foreground or background color to the selected color. It changes which ever color you last clicked on to the new color.
The magnifying glass will increase the viewing size of the image. Click the magnifying glass and click on the image to increase the size. You can also easily shrink and grow the view by selecting ‘View’ from the image menu and selecting ‘Zoom’.
The old fashioned compass tool measures distances and angles. Select the tool, click on the spot you wish to begin the measurement. Drag a line to the second spot and click. A ‘Measure’ window appears with distance in pixels and the angle.
Move looks like a 4 way tire iron. You have a cross shape with an arrow on the tip of each end. Select this and you can move the selected area about on your image.
