Convert OTB FONT to PFA

The OTB file extension, standing for "OpenType Bitmap", is a specialized format used in X11 for bitmap-only font files. It is a variant of the SFNT (scalable font) file format, tailored to store bitmap representations of fonts without vector outlines. Historically, OTB was developed to support the efficient rendering of fonts on systems with limited resources, ensuring the high-quality display of text. This format is particularly useful in environments where rendering performance is critical, such as older display systems or embedded systems.

The PFA (Printer Font ASCII) file extension represents a human-readable version of Adobe's Type 1 font, containing glyph data in ASCII format. Introduced by Adobe Systems, PFA files are used primarily in desktop publishing and graphic design to ensure precise font rendering. These files can be opened and edited with any text editor, making them versatile for font customization. Historically, PFA files were essential for PostScript printers, enabling accurate font reproduction. Today, they remain relevant for specific applications requiring detailed font manipulation.
