PTOCA Format (PTOCA)
The Presentation Text Object Content Architecture (PTOCA) is the data object used in document processing environments for representing text, which has been prepared for presentation. Each file contains one or more pages of text and is always included as part of a document in a MODCA file. Each page may reference a PTOCA Overlay, which is merged with the text as a background.
There is no default extension.
This format originated at IBM.
This file format does not support QFactor, progressive loads and saves, stamps or Lossless JPEG compression, but it does support multi-page files.
For PTK files, you can read the following bits per pixel: 24.
LEAD does not save PTK files.
