This guide will teach you how to apply semi-transparency to solid-colored images that do not have textures.
The Images and media policy states that extremely enhanced images may not be uploaded to the Wiki. That means you must be very careful when following this guide, as you will be recoloring/enhancing images.
Before you begin, you must pick image editing software. This guide uses GIMP, and most image editors here on the Wiki use it as well. Photoshop is a great image editing program, however it is extremely expensive and isn't as simple as GIMP. Some of the features of Photoshop are hard to work with, GIMP has all the features you will need for Wiki-image-needs and it is free. If you choose to use MS Paint, this guide will be impossible for you. Go draw a banana.
This guide will start off with an image that already has normal transparency and is cropped. Click here or [[User:Spineweilder/Screenshots guide|here]] for tips on taking images of things in RuneScape, and click here to find out how to add simple transparencies.
- Load the image you want to add semi-transparency to in GIMP. Add normal transparency to it and crop it. Keep a copy of this one for future reference.
- Select the first part of the image you want to add semi-transparency to using the Lasso tool (if you use Fuzzy Select, ima kill you). When I say "first part", I mean parts of the image that are supposed to have the same shade (see below).
- Once the first areas are selected, go to Colors > Brightness-Contrast, and move both sliders to the max so the area you have selected turns white.
- Then go to one of the following: Colors > Color Balance; Colors > Hue-Saturation; Colors > Colorize (used in this example). Mess with the levels until the correct color of the selected areas is found, or as close to it as possible. Use the original copy of the image to determine the correct color. Also using an eyedropper and changing the brightness levels can work.
- Once the selected areas are properly colored, add transparency with the eraser tool. Move the Opacity slider to pick how much transparency it has. In this example, 22.6% opacity was used. Keep in mind just how transparent the image needs to be - sometimes you will have to use several opacity settings on different parts of one image.
- Next, use the lasso tool to select the next areas to get semi-trans'd. An annoying but failsafe way to do this is to use the Ctrl key with the lasso tool. Press and hold Ctrl then click on the image with the lasso (release Ctrl...), and select the areas that you don't want to be recolored, like the darker sides of the shield and the sigil in the below image. After the areas that you don't want recolored are selected, press Ctrl i - this will invert the selection (therefore the outline of the shield will be edited, and the rest selected will remain untouched). Doing this will keep you from overlapping colors next to each other.
- Repeat steps 3, 4 & 5 for the new areas. After being properly recolored and trans'd, deselect the other areas that you don't want to add semi-transparency to next. To do this, use the Shift key with the lasso tool, and outline the areas, as seen below. This will deselect them so that only the darkest parts of the side of the shield are selected. You don't have to perfectly outline it, just draw a big polygon around the selected area.
- Repeat steps 3, 4 & 5 for the new areas. Congrats! Your image now has semi-transparency. (:
