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. PTOCA overlays can be merged to recreate the original document. This format has many configurable settings including font properties. LEADTOOLS can read single or multipage files.

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.

LEADTOOLS for WPF supports callbacks to load specific overlay files from a specific path.

File constants associated with this file format are:

Required DLL: Leadtools.Codecs.Ptk.Dll. For a listing of the exact DLLs needed, based on the toolkit version, refer to Files To Be Included With Your Application.
