Hi all,
After trying for few hours, I was able to convert the wxImage into an
osg:Image, and apply it as a texture.
I am posting the code below as it might help someone else as well.
Code:
wxBitmap bmp(wximage);
wxNativePixelData data(bmp);
wxNativePixelData::Iterator p(data);
osg::Image* klnFace = new osg::Image();
int tex_width = data.GetWidth();
int tex_height = data.GetHeight();
klnFace->allocateImage(tex_width, tex_height, 1, GL_RGBA, GL_FLOAT);
float* img_data = (float*)klnFace->data();
for (unsigned i = 0; (i < tex_height); i++) {
for (unsigned j = 0; (j < tex_width); j++) {
int ind = i*tex_width + j;
img_data[ind*4] = p.Red()/255.0;
img_data[ind*4+1] = p.Green()/255.0;
img_data[ind*4+2] = p.Blue()/255.0;
img_data[ind*4+3] = 1.0;
p.MoveTo(data, j, tex_height-1-i);
}
}
I used wxNativePixelData to access the raw image data.
Thank you!
Cheers,
Lahiru
