appending on pdf is failing

[pawanshirur]

when trying to append to a pdf i get the following error. ( this code was working in previous version of ghostscript and export_fig)

hostscript error: undefinedfilename in (C:\Users\pshirur\AppData\Local\Temp\tp0821223f_00a5_45d6_be68_84d7995ca24c.pdf)

• perhaps C:\Users\pshirur\AppData\Local\Temp\tpf97e812c_4b46_49a4_b8ba_a4226b0239a5.pdf is open by another application
• or maybe you have another gs executable in your system's path

Please ensure:

• that the function you used (C:\Users\pshirur\Desktop\Pawan_Projects\MATLAB\SystemTesting\G4+_Tenney\export_fig.m) version 3.15 is from the expected location
• and that you did not made a mistake in export_fig's expected input arguments
• and that ghostscript is properly installed in C:\Program Files\gs\gs9.54.0\bin\gswin64c.exe

If the problem persists, then please report a new issue. In your report, please upload the problematic EPS file: C:\Users\pshirur\AppData\Local\Temp\tp2c4965bc_5270_4a40_9b35_4e005db950d1.eps (you can then delete this file).

Did you follow the instructions in the detailed error message? Namely, did you ensure that you are not trying to append to a PDF file that is already in use and that you do not have another Ghostscript installed in your system's path? Also, you did not follow the specific instruction to upload the problematic EPS file. Without any additional information, it is impossible to recreate the error, sorry

p.s. in your call to export_fig, sprintf('%s',rpt) is exactly the same as simply rpt, there's no need to complicate things.

The latest commit includes a workaround for some problems involving PDF append - I have no idea whether or not it resolves your specific problem above, because as I already mentioned you did not provide enough information in your original post.
