Convert OTB to DDS

The OTB (Over The Air Bitmap) file extension, developed by Nokia, is used for transmitting black and white bitmap images between mobile phones, particularly Nokia and Siemens models. These images, with a maximum resolution of 255x255 pixels, are often sent via SMS in either hexadecimal text or binary format. Historically, OTB files were popular in the early days of mobile communication for sending simple graphics, icons, and wallpapers when data transmission speeds were limited.

The DirectDraw Surface (DDS) file extension is used primarily for storing graphical textures and cubic environment maps in the field of computer technology. Introduced by Microsoft with DirectX 7.0, DDS files facilitate efficient loading and storage of texture data, crucial for rendering 3D graphics in real-time applications like video games and simulation software. These files support both uncompressed and compressed formats, leveraging S3 Texture Compression (S3TC) to optimize memory usage and performance. DDS files are indispensable in modern graphics programming, enabling quick texture manipulation and robust graphical asset management.
