(Note that RGB/A support depends on compression type of the source DDS file.)ĭDS files can only be created with square pixel dimensions. About FME RastersĭDS supports rasters with Red8, Green8, Blue8 bands, with an optional Alpha8 band.

The topics below describe how FME processes raster data. The DDS writer supports additional options through the Microsoft DirectDraw Surface (DDS) Writer Feature Type Parameters FME Raster FeaturesįME raster features represent raster data and use several concepts that are unlike those used in the handling of vector data. dds files for format, resolution etc and. Sometimes you just want to quickly open and check. The DDS writer distinguishes duplicate output files by appending numbers to the filenames. dds image files as they are commonly used for textures in games. Writer OverviewįME considers a writer dataset to be a folder name. Note: When reading a DDS file with DXT1/DXT1A compression, it is interpreted as RGB. The DDS file contains pixel data, and each pixel in the file is a point in a single FME raster feature. More about FME Desktop Editions and Licenses.įME considers a single DDS file to be a dataset.More about FME Licenses and Subscriptions.DDS Product and System RequirementsĪvailable in FME Professional Edition and higher Writer options exist to control the compression method and quality of the output DDS files – this impacts both writing performance and file size. RGB/A support depends on compression type of the source DDS file. The files use lossy compression, which means you will lose detail and color information compared to the original texture.ĭDS files are represented as three 8-bit bands (RGB) or four 8-bit bands (RGBA). Since files are compressed in the graphics card memory, they can be decompressed on-the-fly by the hardware. DDS is a Microsoft format for storing data compressed with an S3 Texture Compression (S3TC) algorithm.ĭDS files are often used to store textures.ĭDS files store compressed and uncompressed pixel formats. Microsoft DirectDraw Surface (DDS) Reader/WriterįME can read and write DDS raster data and textures.Ī DDS (Microsoft DirectDraw Surface) file is a raster image saved in the DDS container format.
