I am manipulating an InDesign docment from MATLAB:
Which language is this?
MATLAB is the language. It makes use of the COM Interface for InDesign.
The method to export is called exportFile for the JS interface, I am not sure if it's named Export for the COM interface. You can check this out
Another thing that I see could be a potential issue is that according to the link below
It says that "The MATLAB COM Interface does not support invoking functions with optional parameters". So if this means that we need to explicitly pass on all the params then you seem to be lacking some parameters, try passing them on.
Thanks for the input. For the COM interface (and Visual Basic Script) the funciton is Export. Even when I add all the optional parameters, there is still an issue with the first parameter: idExportFormat.idInteractivePDF.
I don't have anything setup to test it out personally. But what is the error message that you get, maybe that provides us with a hint. Try doing the same thing using VB, probably the syntax and the constants are the same in both.
This form of the Export function, below, works in VBScript, but gives this error in MATLAB: "Unable to resolve the name idExportFormat.idInteractivePDF."
b = doc.Export(idExportFormat.idInteractivePDF, 'C:\TEMP\Test-2.indd', false)
The form below, with single quotes, should work similarly to the VBScript version, but errors.
b = doc.Export('idExportFormat.idInteractivePDF', 'C:\TEMP\Test-2.indd', false) Error using Interface.1A5E8DB4_3443_11D1_803C_0060B03C02E4/Export Invoke Error, Dispatch Exception: Source: C:\Program Files\Adobe\Adobe InDesign 2022\InDesign.exe Description: The specified object does not support the desired export format.
I get the same error when specifying all the arguments.
b = doc.Export('idExportFormat.idInteractivePDF', To, showingOptions, 'InDesign.Document.PDFExportPresets', 'InDesign.Document.PDFComments', false)
These arguments are okay: 'InDesign.Document.PDFExportPreset', 'InDesign.Document.PDFComments'. Accessing objects under Documents is not a problem. But accessing the idExportFormat enum in the InDesign namespace doesn't work.
I also tried variations of the above with 'InDesign.idExportFormat.idInteractivePDF' as the first argument, but get the same error: "The specified object does not support the desired export format.".
Ok, that is interesting. Just use that constant to assign it to a variable, to see if the constant is the issue or method call. I now doubt that maybe the call of the function is not at all possible because it's defined with optional arguments, this could be verified if we are able to assign the constant to a variable but not use it in this method call.
