There's been a terminology change between the AlterCast 1.5 documentation and the Adobe Server documentation. Read this article only if you are already familiar with the terminology in the AlterCast 1.5 docs.

Issue
The AlterCast 1.5 Commands Reference lists "Applicable file formats" as:

1. PSD
2. GIF (converted internally to PSD by AlterCast)
3. PNG (converted internally to PSD by AlterCast)
4. JPEG (converted internally to PSD by AlterCast)
5. TIFF
6. SVG
7. XML

The Adobe Server documentation now refers to the first five types as Raster content. Is this just a change in terminology or is it a behavior change?

Applies to
Adobe Graphics Server
Adobe Document Server

Solution
It's just a terminology change. The first 5 types above are now referred to as Raster content.

When you load a file into Adobe Server, it is held internally as content of a particular type. Content types are internal Adobe Server formats that correspond generally, but not exactly, to file formats. For example, the Raster content type is a PSD-like format that Adobe Server uses to store and manipulate all image types. Adobe Server transforms file content to an internal content type upon load, and transforms content types to various file formats upon save.

The section on "File and Content Formats" in the Commands Reference includes a table that summarizes the content types and their relations to file formats.

- page 9 of the Adobe Document Server Commands Reference

Old Description
In AlterCast 1.5 the imageSize command was described in part as:

Applicable file formats:
• PSD
• TIFF
  

New Description
In the Adobe Server Documentation this information for the imageSize command is presented as:

Content Types
Input: Raster
Output: Raster

The above means that any of the following can be inputs or outputs: PSD, TIFF, GIF, JPEG, PNG. (For some commands, the input and output types will differ.)
