Convert BMP to PBM

The BMP (Bitmap Image) file extension is a raster graphics format used primarily for storing digital images. Developed by Microsoft, BMP files retain high image quality due to their lack of compression, making them ideal for preserving detailed and colorful images. Introduced in the early days of Windows, BMP's simplicity and widespread compatibility have cemented its role in digital imaging, despite being superseded by more efficient formats in many applications.

The PBM (Portable Bitmap) file extension, part of the Netpbm project, originated in the late 1980s to facilitate efficient and portable graphics file interchange. Primarily, PBM files are used to store monochrome bitmaps in a simple ASCII text format, ensuring easy compatibility across different systems and platforms. This format supports only black-and-white imagery, making it particularly useful in scenarios where simplicity and minimalism are prioritized, such as in Unix environments for bitmap manipulation and transfer. Its historical significance lies in promoting a standardized approach to bitmap graphics in early computer technology.
