This DirectXTex sample is a command-line texture utility for creating DDS files containing cubemaps, volume maps, or texture arrays from individual images.
This utility does not support mipmap generation or texture compression, but the resulting .DDS file can be further processed by the [[Texconv]] utility. Any texture compressed input file is decompressed on load.
# Examples
texassemble -volume -w 256 -h 256 -o volume.dds lena.jpg fishingboat.jpg peppers.tiff
This loads the three image files 'lena.jpg', 'fishingboat.jpg', and 'peppers.tiff', resizes them to 256 x 256, and then writes out a volume (3D) texture to 'volume.dds' sized 256 x 256 x 3 with each input image as a depth slice. The result uses a DXGI format derived from the 'lena.jpg' input image, or one could be provided via the '-f' command-line switch. _The result does not have mipmaps but 'volume.dds' could be use as input for **texconv** to finish the processing such as generating mipmaps or block-compression._
texassemble -cube -w 256 -h 256 -o cubemap.dds lobbyxposjpg lobbyxneg.jpg lobbyypos.jpg lobbyyneg.jpg lobbyzpos.jpg lobbyzneg.jpg
This loads the six image JPEG files, resizes them to 256 x 256, and then writes out a cubemap texture to 'cubemap.dds' sized 256 x 256 with six faces, with each input image as a distinct face (ordered positive-x, negative-x, positive-y, negative-y, positive-z, and negative-z). The result uses a DXGI format derived from 'lobbyxpos.jpg', or one could be provided via the '-f' command-line switch. _The result does not have mipmaps but 'cubemap.dds' could be use as input for **texconv** to finish the processing such as generating mipmaps or block-compression._
texassemble -array -o array.dds lena.jpg peppers.tiff
This loads the two image files 'lena.jpg' and 'peppers.tiff'. It resizes 'peppers.tiff' to the same size as 'lena.jpg', and then writes out an array 2D texture to 'array.dds' using the two input images. The result uses a DXGI format derived from 'lena.jpg', or one could be provided via the '-f' command-line switch. The result does not have mipmaps but 'array.dds' could be use as input for texconv to finish the processing such as generating mipmaps or block-compression. Note that loading 'array.dds' requires feature level 10.0 or better hardware.
