The second image is using the RCT2 palette with no dithering. The third image is using the RCT2 palette with dithering. + + + + + +### Requirements: +* Photoshop (the previewed version is CS6) +* Another tool for editing images with transparency (such as Paint.NET, if you're not already skilled with Photoshop) +* RCT2 Pal files (found below) + +### Files: + +* [With Water](http://openrct2.github.io/files/palette_water.pal) - This should be used for any image being drawn in the intro scene, title screen, rollercoaster designer, or track manager as they will never have a different water palette. + +* [Without Water](http://openrct2.github.io/files/palette_no_water.pal) - This should be used for any image being drawn in a scenario or the scenario editor since the water palette may be different. + +### Instructions: +* Download the RCT2 pal files. +* Open up your image in Photoshop. +* Transparency needs to be used for the background, otherwise the edges of the image won't look right after being converted. +* If the edges of your image are (or are close to) pure white, you may have a problem when adding transparency to your image. + + + +* Goto *Image > Mode > Indexed Color...*. + + + +* The Indexed Color window will pop up. +* Open the *Palette* drop-down and select *Custom...*. + + + +* The Color Table window will pop up. +* Click *Load* to open one of the two pal files you downloaded earlier. +* In the *Files of type* drop-down select *Microsoft Palette(R) (.Pal)* and then locate the RCT2 pal file. + + + +* Now you can color your image using dithering. +* You can change the *Amount* percentage between 1%-100% however somewhere around 50% usually looks best. The image will update as you change the value. +* Click OK when you're done. + + + +* Now you have your image with the correct palette, but there's no transparency. +* I've found adding transparency with Photoshop is more complicated than just using another image editor. So if you know how to do it in Photoshop then go ahead. +* Copy the entire image and paste it in your alternative image editor. +* Next fill in the white background with transparency. This is where problems may occur if the edges of your image were already white. + + + +* And you're done. Save the image in the resources/g2 directory as a numbered png and you're good to go. \ No newline at end of file
