[gradsusr] [EXTERNAL] Re: white lines on pdf after Mac update to Catalina

[Kyle Clem]

Thanks for your reply Lyndz and Jennifer.

Jennifer-the white lines appear when opening the .pdf in Preview (as you mentioned), but also in Powerpoint and Google Chrome. Are you implying that the white lines are unavoidable (for a .pdf) except when using more sophisticated software such as Adobe Pro and/or those used by production teams in publication?

So essentially to avoid these white lines for Powerpoint presentations, etc, I should use a .png or similar? The only headache here is the different looks of .png versus .pdf so this would require editing the plot specifications when going back and forth.

Thanks,
Kyle

It is not a problem with the graphics library in GrADS, it is more of an issue with the .pdf rendering software. The Preview App on Mac is not as good as Adobe Pro (you get what you pay for), and you won’t see those lines in professionally published articles.

Hi Kyle,



I just posted a similar problem several days ago.



They said that this is related to the graphics library.

Try to use a different output format (PNG or JPEG).



Also for other related issues, try a google search: "site:gradsusr.org<https://apc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Furldefense.proofpoint.com%2Fv2%2Furl%3Fu%3Dhttp-3A__gradsusr.org_%26d%3DDwMFaQ%26c%3DApwzowJNAKKw3xye91w7BE1XMRKi2LN9kiMk5Csz9Zk%26r%3DM2mFZsxo0ZoztoK2Lyoypu1kKkBVKyEoM9CXGWO42zk%26m%3DIK_PD7K_-OIiIVn2rBSVmskcQT2ALHPJ6ZPADyUlKeY%26s%3DjPP8aph0wR0jGd6doaJKrOP60rNa7yNpqjbb5_dd3zY%26e%3D&data=02%7C01%7Ckyle.clem%40vuw.ac.nz%7C7f19860086384bddb3be08d8272b00dd%7Ccfe63e236951427e8683bb84dcf1d20c%7C0%7C0%7C637302413022415700&sdata=Ti85E12c1jdQTmkg7ODU4RNj95u0lrVwHVLUlsEvn90%3D&reserved=0> pdf  lines"

Hi GrADS users,



I recently updated my MacBook Pro to Catalina. I am running GrADS v2.1.1, and pdfs that I print now contain white lines (see example pdf attached) using the following syntax:



   'gxprint test.pdf white'



Does anyone know why or how to fix this?



Thanks,

Kyle
