The attached zip file has 4 images scaled up from 32x32 to 128x128. All done with GDI.
The scaling is done with the following API.
HANDLE CopyImage(
HANDLE hImage, // handle to the image to copy
UINT uType, // type of image to copy
int cxDesired, // desired width of new image
int cyDesired, // desired height of new image
UINT fuFlags // copy flags
);
You can thank Vortex for decyphering this one.
