wxImage sizeof pixel

[Todd Mars]

HI!

Is this true for now? (correct I mean) To get byte size of pixel data
in wxImage:

int GetPixelSize(wxImage &img)
{

if (img.HasAlpha())
return 4;
return 3;
}

Thanks!
Todd.

I mean as stored in wxImage, or is the 'Alpha' channel a seperate
array, seperate from the data?

They're separate. See the documentation for GetAlpha() and GetData():
