- Description
- An OTF file is a font file saved in the OpenType format developed by Adobe and Microsoft. It combines aspects of the PostScript and TrueType font formats. OTF fonts are fully scalable, meaning the characters can be resized without losing quality.
- Group 4 (G4) used for black and white lossless compression to maintain high-quality images, commonly used in TIFF format compression by fax machines. A picture is seen as black dots and lines on a blank page; the fewer the dots and lines are, the lesser the file size.
