DXT1 to DDS

Useful information about DXT1

Extension: DXT1
Name: S3 Texture Compression - Dxt1
Mime Type: image/dxt
Converter: DXT1 Converter
Description: A DXT1 compressed image is an RGB image format. As such, the alpha of any color is assumed to be 1. Each 4x4 block takes up 64-bits of data, so compared to a 24-bit RGB format, it provides 6:1 compression. You can get a DXT1 image by using the as the internal format of the image. Each 4x4 block stores color data as follows. There are 2 16-bit color values, color0 followed by color1. Following this is a 32-bit unsigned integer containing values that describe how the two colors are combined to determine the color for a given pixel. The 2 16-bit color values are stored in little-endian format, so the low byte of the 16-bit color comes first in each case. The color values are stored in RGB order (from high bit to low bit) in 5_6_5 bits. The 32-bit unsigned integer is also stored in little-endian format. Every 2 bits of the integer represent a pixel; the 2 bits are a code that defines how to combine color0 and color1 to produce the color of that pixel. In order from highest bit to lowest bit (after the little-endian conversion), the pixels are stored in row-major order. Every 8 bits, 4 2-bit codes, is a single row of the image. - Source

Useful information about DDS

Extension: DDS
Name: DirectDraw Surface
Mime Type: image/vnd-ms
Converter: DDS Converter
Description: The DirectDraw Surface container file format (uses the filename extension DDS), is a Microsoft format for storing data compressed with the previously proprietary S3 Texture Compression (S3TC) algorithm, which can be decompressed in hardware by GPUs. This makes the format useful for storing graphical textures and cubic environment maps as a data file, both compressed and uncompressed.[2] The file extension for this data format is dds. - Source
