But I have no luck with floating point values. I use SAMPLEFORMAT_IEEEFP sample format along with 32 bits per sample.
All the pixel values are issued from an 8 bit/sample image, with no conversion or multiplication applied to them.
When I open the file with some well known image editor, the image is completely saturated, all white with values 32767...
Where should I look?
Most applications don't support floating point images like this. My application (GraphicsMagick) does, but in a somewhat crude way. Some applications like GDAL are designed for floating point and should do a lot better.
Recent Photoshop (CS2 and later) provide some support for floating point images.
