Psvelo with a warning message

Q&A
1

Dear

I got the warning message when I opened an eps file.
gmt(6.4.0)
gs(10.02.0)

Converting the PostScript file “windsticksn_time_from_erddap_881srz_from2021_2024_explanation_ecmwf.eps” produced the following warnings:
· % Warning: /SetTransparency pdfmark ignored: Unknown %

The command I run was as follows,
gmt psvelo time_v_11_03_2024_stick.txt -Se150/150 -D0.2 -Gblack -W0.7p,blue -A10p+e -R -B -J -O -K>>windsticksn_time_from_erddap_881srz_from2021_2024_explanation_ecmwf.eps

Could you tell me how I can avoid the warning?

Regards,

takaya

And the other commands before and after this one?

Hi @takayanamba. Just from looking at your GMT and Ghostscript versions, I am wondering if the problem is that transparency in GMT 6.4 does not work correctly with gs 10.02. You can either update to GMT 6.5 or downgrad to gs 9.56.
