Convert pfb to otb

What is the difference between .pfb and .otb?

Description: A Printer Font Binary (PFB) file is a type of font file used specifically in the context of Adobe Type 1 fonts. It stores font data in a binary format, which includes the glyph shapes and font metrics necessary for rendering text accurately on screens and in print. The PFB file is typically used in conjunction with a metric file (with an .AFM or .PFM extension) that provides additional layout information. This file format was widely used for high-quality typography on PostScript printers.; The OTB (Nokia Over The Air Bitmap Image) file format is a type of image file developed for use on Nokia mobile devices. These files are specifically optimized for efficient transmission and display on Nokia phones, particularly older models. The OTB format is designed to be compact to facilitate over-the-air (OTA) transmission, which was an essential feature in the era of limited bandwidth and data transfer capabilities. The format supports monochrome graphics, making it suitable for simple images like icons and logos.
