# Traveo2BitmapConverter #### Description This document provides a complete list of bitmap formats supported by the Traveo2 Target. The formats are grouped into categories such as **Basic**, **Grayscale**, **RLE (Run length Encoding)**, **RLA (Run-Length Adaptive)**, **RLAD** (**Run-Length Adaptive Dithering)**, **CLUT** (**color lookup table)**, **JPEG**, and **YUV**. Below are the supported pixel formats with their corresponding type, format code, and a brief description. These bitmap converters are supported only on the target. Windows simulation uses the default bitmap converter. #### Traveo2 Bitmap Format List ##### Basic Formats These formats represent the fundamental bitmap types supported by Traveo2, defining basic RGB and alpha channel combinations with different bit depths for color and transparency.
