Photoshop Text Engine Data
From Just Solve the File Format Problem
Photoshop Text Engine Data (also called EngineData) refers to a data format primarily used as a component of Adobe Photoshop PSD format. It is presumably used for the editable text elements.
Format details
The format looks a little like PDF, but only a little. It uses "<<" and ">>" to delimit hierarchical data structures. Keywords are introduced by a "/" character. Examples of keywords are "EngineDict", "ResourceDict", and "ParagraphRun".
Although it is a text-based format, it contains text in multiple incompatible character encodings (perhaps ASCII and UTF-16), so it may require special tools to properly view and edit.
The format can be found in at least two different places in a PSD file:
- In a tagged block whose key is "Txt2"
- In a descriptor item whose key is "EngineData"
See the PSD specification for an explanation of these terms.
