Convert OTB to PALM

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 PALM file extension, standing for Palm Pixmap, is a bitmap image format used by Palm OS mobile devices. It stores logos, clipart, photos, and other images for display in Palm OS applications. Originating from the now-discontinued Palm OS, the PALM format evolved through several versions, with later iterations supporting transparency and run-length encoding compression. PALM files are compatible with various operating systems, including Windows, Linux, and Mac OS, and can be opened and converted using tools.
