Saving higher resolution graphics

sullivan0822 — Wed, 11 Jun 2008 18:25:22 GMT

After modifying the device drivers, finally am getting higher resolution on my graphics files. My main problem now is there seems to be a whole layer of the image (PROC BOXPLOT, and GPLOT, GCHART) missing from the output. The plot axes are black and visible on the screen but either missing or white or possibly hidden (?) on the .tiff file. I imported one into powerpoint and could just make out a faint outline. Also affected are the bars / fences on boxplots, lines from an annotate dataset (but not the text). I can get around it by doing an 'export as image' which is OK once in a while but not very automated. Any advice would be appreciated - or any other tips on improving the resolution on gif / jpeg / tiff files.

Sullivan,
With no code, the reader have no idea of what you have tried.
As in graphic matter, the environment is important what can we conclude about your try
-are you working outside any ods? probably
-were you utilizing the target in place of device goptions in order to see the 'raw but real' appearance of your ourput
-but tiff is surprising except if you have precisely indicate some dimension for your graph
as vsize and hsize
- about resolution take a look at Phil Mason text at the end
http://www.cmg.org/measureit/issues/mit48/m_48_11.html
but perhaps as you were speaking about 'modifying device drivers' you know this already.

In any case, even if your try was of high level, it could interest some graphical sasuser with practice to see how you already got results, before any person of the Sas team answer

I am having the same problem as Sullivan. Below is my code, which does produce a TIFF image at the dpi I need. The journal specifies that figures are in a .tiff format at 800 dpi. However, lines for the axes around the boxplot and around the blocking variable are very, very faint when I print the graph and on my computer screen when I view the image in Microsoft Office Document Imaging. The lines for the whiskers are also very faint even if increase the lfactor=8. This problem occurs when I insert the picture into a Word document. When I look at the graph output in SAS, all the lines are thick and crisp.
Thanks,
Mike

I suspect the lines are still one pixel thick, which at 800 DPI makes them 1"/800 thick. Have you tried changing axis width?

Kindly - suggestion to OP - don't piggy-back on another author's post - create a new one and provide a hyperlink (pasted in your post-body) with your pertinent details.
