ScriptRST is a tool which have differents features. Most of them are for PNG, for testing differents methods to set PNG transparency with PNG32 files. It can also create JPG with Alpha file to simule JPG transparency, or can reduce noise for JPG files.

| Option Name | What it does |
| Reset PNG | The file is encoded to PNG24+Alpha, with no compression and no filter. It also deletes all unecessary chunks. |
| Delete tRNS | It can delete Transparency -Alpha Channel, tRNS chunk- of PNG Files. You'll not have any transparency after application, and the RGB data are stored on a white background (no bKGD chunk specified, background integrated). |
| Set Background Color | This option set a fixed background like the Delete tRNSoption, but with a custom value (edit the ScriptRST to set the hexadecimal value to BackgroundColoroption). |
| Black Pixels | This option convert all not displayed pixels to Black (0,0,0) in the RGB area. |
| RGB Filtering | This option does Black Pixels (f0), and also tries all others filters in the RGB area (f1, f2, f3, f4). It also tries to keep the RGB area intact to compare results, and give the best output. |
| Genere All | This option genere all files created by option from 1 to 6, without choosing the best output. |
| JPG and Alpha | This option extract the RGB data of a PNG32 file and convert it to JPG. Then, it extracts the Alpha Channel to use JPG with Alpha. See Fake Transparency with JPG. |
| JPG Noise Filter (not displayed) | This feature is only available when you drop JPG files on the ScriptRST. Process run automatically, and will reduce the noise in the JPG frame, before applying a strong optimization. This option is very useful for images which have a lot of artifacts, as JPG files with quality lower than 70. You can see an example of reducing noise with JPG. |
Drag-And-Drop your files ON the ScriptRST. For optimal optimization, always name your file as namewithtoutspace.png
instead of my file name with space.png
. Always use standard characters. Do not store ScriptRST in a folder name with space like New Folder
.
ScriptRST does NOT support animated or interlaced PNG files. You can edit ScriptRST.cmd to set :
| Option Name | Accepted Values | What it does |
| BackgroundColor | 00000 to ffffff | Set the Background color with hexadecimal value. |
| JpgQuality | 1 to 100 | Affect the output image quality for JPG files. |
| AlphaQuality | 1 to 100 | Decrease the number of colors in the Alpha Channel. |
