Convert OTB FONT to OTF

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.

OTF, or OpenType Font, is a scalable font format used for both screen and print applications. Developed by Microsoft and Adobe in the mid-1990s, OTF files support advanced typographic features, such as ligatures, small caps, and alternate glyphs, providing enhanced control over text design and layout. It combines the best aspects of PostScript and TrueType fonts, making it versatile for various digital platforms and operating systems. Due to its robust capabilities and broad compatibility, OTF remains a preferred choice for professional designers and typographers.
