how to convert image by script runner in act editor?

[dreamsambit]

I use this script

            Layer layer = act[selectedActionIndex, selectedFrameIndex, 0];
            GrfImage image = layer.GetImage(act.Sprite);
            image.Convert(GrfImageType.Indexed8);

script can convert image to Indexed8

 it can run ,but when I want to save , will get a error

 

--------------         Exception         --------------

System.IndexOutOfRangeException: 

    GRF.FileFormats.SprFormat.SprAbstract._writeAsBgra32(BinaryWriter writer, GrfImage image)

    GRF.FileFormats.SprFormat.SprAbstract._saveAs(Spr spr, String filename, Byte major, Byte minor)

    GRF.FileFormats.SprFormat.SprConverterV2M1.Save(Spr spr, String filename)

    GRF.FileFormats.SprFormat.Spr.Save(String path)

    GRF.FileFormats.ActFormat.Act.SaveWithSprite(String actPath, String sprPath)

    ActEditor.Core.ActEditorWindow.SaveAs()

-------------------------------------------------------

 

I don't know how to change "writeAsBgra32" to "writeAsIndexed8".

You can simply right-click the image and convert it:

 

I'm not sure what you're trying to do here.

 

Edit: The script up there will break the SPR format. I should really remake that tool's interface, was a bit messy at the time.

Bgra32 images take a lot more space than indexed8 images. Indexed8 images are RLE compressed while bgra32 images are just raw data. Either way, putting them in a GRF will compress your files so there's no real need to worry too much about that.

I have some .spr and i want to reduce they file size

original size is 392KB ,and after convert will become around 70KB

but have more then 300+ files and about 40 image in each spr file.....

Thank you for your comment.

 

BTW,I find a way to convert Indexed8.

just use PhotoShop convert image into indexed format ,and then add that into sprite,merge palette.
