Hi,
I have been doing some image stuff lately. JPEGs and PNGs load right but
BMPs are upside down. Is this a feature or a bug?
At the moment I am doing this for remedy:
Code:
osg::Image* image = osgDB::readImageFile(filename);
if(filename.substr(filename.length()-3) == bmp) {
hey ulrich,
I am not sure I understand. I am loading a bmp and use it as a texture on a
quad. I use the same texture coordinates for various image types but only the
bmp displays upside down.

Then I would say your BMP is upside down ;-)
I have a stack
Bitmaps are stored upside down internally. If the loader is not
flipping your image, then flip the image yourself.

Bitmap data
This block of bytes describes the image, pixel by pixel. Pixels are
stored upside-down with respect to normal image

So I record it is not a bug in the image
