Convert OTB to CUR

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 CUR file extension, short for Cursor Image, is a format used in Microsoft Windows for cursor icons. Its primary use is to display and manage custom cursor images, enhancing user interaction with graphical user interfaces. CUR files, a variant of ICO files, were introduced in early versions of Windows to enable animated and static cursor designs, elevating visual and functional user experiences. The structure typically contains image data, including multiple resolutions and color depths, which ensures adaptability across various display settings in Windows environments.
