SDK: Get Images data

[Marc477]

In the Sketchup c++ SDK:

What is the equivalent of SUTextureGetImageData for a SUImageRef? How can I access images pixel data?

Thank you

Hmm... it looks like this might be missing. I'll double check and file an issue if it's truly missing.

Any work around ?

Not that the API provides. You could extract to a temp file and read it.

I'm not sure how I am supposed to extract the image to a file, if I cannot read its data.

There are no methods to read (or modify) individual pixels, but you can export a material's texture image using Sketchup::TextureWriter.
Create a temporary group (so the material doesn't have any distortion), apply the texture and load it to the texture writer.

Update - SUImageGetData should be equivalent.
