ViewDDS

ViewDDS is a "testing tool" for DDSPanel and DDSFile components of s3pi.

It allows importing images in any "Windows supported image format" (PNG, JPG, etc) and conversion to DDS. You can also import a separate alpha-channel image (presumed to be monochrome). The DDS format can be DXT, non-DXT RGB or a Luminance map. The format and size can be edited for an existing image.

The tool also allows applying HSV shifts and importing and applying HSV shifts, RGB values and images, subject to channel masks.

The resultant image can be saved as a DDS or exported to one of the supported formats.

Important Note

The program is "tolerant" of features within DDS files that it does not support when reading them. However, it will only process simple, single texture files and saving the DDS will only save one texture. (Multiple mipmaps, volume maps and cube maps are not fully supported.)
