RuneScape:Editing/Introduction to GIMP

To effectively edit images on the wiki you will need a decent image editing program. For more advanced edits, such as adding transparency to images, you will need a program that has layer capabilities. You can use any program that is capable of doing so to edit images for the wiki; however more basic programs such as MS Paint will not be effective.

Many wiki editors use GIMP for image editing. GIMP is straight forward to learn how to use and can be downloaded for free here. The rest of this guide will cover how to use some of GIMP's basic functions and tools.

Layers - Gradients

The Layers window is useful for keeping track of what you're doing when working on an image with layers e.g. when adding translucency. You can open this window using the Windows menu if you have closed it.

All layers are shown in this window. The image's layers are viewed in the order they appear in the window: layers at the top of the window are shown at the foreground of the image. You can the layers' order by dragging layers up or down

The eye icon changes visibility of layers.

Right-clicking on a layer allows you to access several functions:

  • New Layer... creates a new layer which you can choose the size and fill colour for.
  • Merge down merges the active layer with the next visible layer
  • Delete Layer
  • Layer Boundary Size... can be used to increase the size of a layer without scaling the image without changing the size of the content of that layer.
  • Layer to Image Size can be used to increased the size of a layer to match the size of the image.
  • Merge Visible Layers merges all layers which are currently visible.

Toolbox - Tool Options

The Toolbox window allows you to chose different tools for image editing and adjust their options. You can open this window using the Windows menu if you have closed it.

Selection tools

The Rectangle Select Tool ( GIMP - Rectangle Select Tool icon.png ) and Ellipse Select Tool ( GIMP - Ellipse Select Tool icon.png ) can be used to make a selection in these shapes. Can be used to make a selection for cropping, if you have not applied transparency. The tools can also be chosen by pressing R or E on your keyboard.

The Free Select Tool ( GIMP - Free Select Tool icon.png , F) is used to hand draw selections when adding transparency and translucency to images.

The Fuzzy Select Tool ( GIMP - Fuzzy Select Tool icon.png , U) and Select by Color Tool ( GIMP - Select by Color Tool icon.png , Shift + O) tools can be used to add transparency easily to inventory icons.

Color picker

The Color Picker Tool ( GIMP - Color Picker Tool icon.png , O) can be used to select a colour from an image. Useful for selecting a colour for reconstructing particle transparency.

Move

The Move Tool ( GIMP - Move Tool icon.png , M) can be used to move layers and selections, depending on how the tool options are set.

  • Layer > Pick a layer or guide selects the layer clicked on as the active layer. Hold down your mouse button to move around the layer you have selected.
  • Layer > Move the active layer moves the currently active layer.
  • Selection moves the selection tool area.

Alignment

The Alignment Tool ( GIMP - Alignment Tool icon.png , Q) can be used to align layers in images. This is necessary for arranging the various elements of advanced maps.

Rotate

The Rotate Tool ( GIMP - Rotate Tool icon.png , Shift + R) can be useful for correcting images that have been taken at an unnatural angle to a more neutral position - use the slider to rotate the image.

Scale

The Scale Tool ( GIMP - Scale Tool icon.png , Shift + T) should not generally be used. Increasing the size of images using it will make them blurry and decrease their quality. It can be useful for decreasing the size of things when making maps.

Text

The Text Tool ( GIMP - Text Tool icon.png , T) can be used to write text and format it.

Paintbrush

The Paintbrush Tool ( GIMP - Paintbrush Tool icon.png , P) can be used for drawing onto an image. This is not generally used, except in editing particle transparency.

Eraser

The Eraser Tool ( GIMP - Eraser Tool icon.png , Shift + E) can be used rub out parts of an image - this is not generally useful for editing images for the wiki, except in adding translucency.

Blur

The Blur/Sharpen Tool ( GIMP - Blur Tool icon.png , Shift + U) is used to tidy up after adding translucency.

It can also be used to create a blurred effect of images of content which has feathered edges, e.g. leaves on trees and feathers, rather than the usual sharps edges. To do this set the Tool Options to a small size brush (~7) with a high blur rate (~30).
