Compression using Quality_Fastest and Format_DXT5 causes an unhandled exception #48

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The following snipped of code produces an unhandled exception when run:

nvtt::CompressionOptions compressionOptions;
compressionOptions.setFormat( nvtt::Format_DXT5 );
compressionOptions.setQuality( nvtt::Quality_Fastest );

Although the following works:

nvtt::CompressionOptions compressionOptions;
compressionOptions.setFormat( nvtt::Format_DXT5 );
compressionOptions.setQuality( nvtt::Quality_Production );

This was tested on Windows XP using nvidia-texture-tools-2.0.2.  The NVidia
Texture Tools are compiled in Debug without CUDA support.

I should add that the exception produced is as follows:

*** Assertion failed: block->color.col0.u > block->color.col1.u
On file: ...\nvtt\fastcompressdxt.cpp
On function: nv::compressBlock_BoundsRange
On line: 332

This is a dupe of issue 34, which is fixed in trunk, and 2.0 branch. The fix 
will be
in the 2.0.3 release.

Thanks for the quick reply. Sorry for any inconvenience resulting from my not
realizing that this was already fixed.
