| Description | RLA (Run-Length Encoding Algorithm) is a raster image file format developed by Wavefront Technologies for storing images and associated metadata. It is primarily used in the computer graphics industry for exchanging data between different 3D modeling and animation software. |
| Technical details | The RLA file contains both image data and metadata, such as resolution, aspect ratio, color space, and alpha channel information. The image data is stored using a lossless run-length encoding algorithm, which compresses the data by encoding runs of identical pixels as a count followed by the pixel value.
The RLA format supports both 8-bit and 16-bit color depths, and can also store multiple layers of image data, allowing for the storage of depth, motion blur, and other data associated with a rendered image. In addition, the format supports transparency and can store alpha channel information.
RLA files can be opened and edited in many 3D modeling and animation software packages, including Autodesk 3ds Max, Maya, Softimage, and Cinema 4D. However, due to its proprietary nature, the RLA format is not as widely supported as other image formats such as JPEG or PNG. |
