All plug-ins and renderers can be started without Python. The Python installation is checked only when Python is really needed (i.e. when a script starts with #!py). If the installation is missing, Python scripts return the error 1. For the first Python script, a corresponding warning message is also shown. The following Python versions are expected:

By the way, you can have any other, even newer Python version(s) installed. These versions are ignored by the priint:comet plug-ins and by comet_pdf.

Please note: In contrast to v4.x, v5.0 requires the Python version 3.12.

For the installation of the plug-ins we strongly recommend the installers provided by WERK II.

If, for any reason, a manual installation is necessary, it is important to replace all (but not more) plug-ins. Replacing individual plug-ins of different releases will crash Illustrator®. Here you can find complete zip sets of the plug-ins.

For information about the System Requirements for Illustrator see here.

All plug-ins are supplied in the so-called Universal Architecture and run on both Intel and Silicon machines. At least macOS Version 12 (Monterey) is required for all priint:comet plug-ins.

All plug-ins are checked against malware by Apple. However, since you did not get the plug-ins from the App Store, it is necessary to change the security settings of your System Settings:

  1. Choose Privacy & Security in the sidebar
  2. Click General on the top.
  3. Under the point Allow apps downloaded from select Choose App Store and identified developers.

 Installer of v5.0 not working on Windows

After installing the new v5.0 plug-ins, Illustrator® crashes on startup on Windows.

The new installers are fixed accordingly

TW 3286001 - Logger not working

I’m trying to log messages in some scripts. To configure that, I’ve added a log.xml. But unfortunately none of my attempts are working and the the requestesd logfile is not written.

To improve performance, we have revised the entire logging system in 5.0 R35824. Unfortunately, a few errors have crept in - including the fact that many messages are no longer written in the presence of a log.xml configuration. This is fixed now and the logging system should work as before (but significantly faster).

TW 3289137 - AI-Plugin / Python / comet.frame.moveTo does not work with group frames

I have an Illustrator document with two frames which are grouped. If I select one of the grouped frames, three frames are selected:
- two real frames with content
- the group frame.

When I try to move the list of selected frames to a new position, I get the following error message:

Parameter 'frames' is not list[CFrame] or is empty

comet.frame.selected will no longer return CGroup instances.

[Fixed]
Enabling logfile writing does not work.

Enabling writing to a logfile using the Illustrator menu does not seem to work.

[Fixed]
comet.getVersionMajor and comet.getVersionMinor return str instead of int

The Python functions comet.getVersionMajor and comet.getVersionMinor return str instead of int.

[Fixed]
TW 3290207 - comet.file.downloadWebImages wrong result entries on failed downloads

The Python function comet.file.downloadWebImages returns a list of results containing error codes.
When an invalid URL has been provided, the resulting error code is still 0 (success).

[Fixed]
TW 3290251 - Python - wrong parameter in comet.CFrame.setBarcode

The Python function comet.CFrame.setBarcode has multiple problems:

  • The 'options' parameter expects a str but raises an error saying it expects list[str].
  • Even when the 'options' parameter is correctly passed, the function raises an error.
  • The default values for parameters width, height, offsetX and offsetY do not seem to work.

[Fixed]

v5.0 R35824

05.12.2024

 Python improvements

General improvements:

  • Omitting a return value from the main function now no longer causes an error, but a warning is put into the logfile and a return value of 0 is assumed.
  • CProduct can now be tested for equality against other products.
  • product.create now has an ID parameter to directly initialize the product ID.
Faster logfile writing

We managed to refactor logfile writing, resulting in greatly improved performance.
