Help with ps2raster Cutting Off Image

[Kwok, Marcus B.]

Hello,
I am programmatically generating an EPS file using GMT, and then converting it to PNG using ghostscript. However, when I use ps2raster, part of the file gets cut off.

I have reduced my "script" to a pretty minimal example that demonstrates my issue. The size of the image is supposed to represent a letter-size (8.5"x11") sheet of paper, with "UNCLASSIFIED" printed in the top right and bottom left corners (in the production map, there are additional annotations on the page as well). After running ps2raster, the "UNCLASSIFIED" at the top of the image gets cut off, and the margin on the right side of the map is now smaller.

pscoast -R-180.0/180.0/-60.0/90.0 -B30g15/30g15 --PLOT_DEGREE_FORMAT=dddF --DEGREE_SYMBOL=degree -JQ0.0/8.5i -G178/255/178 -S130/239/255 -Dc -W -K --PAPER_MEDIA=letter+ > test.eps

pstext classification.txt -JX8.5i/6.5i -R-4.25/4.25/0/6.5 -N -O --PAPER_MEDIA=letter+ >> test.eps

ps2raster test.eps -E72 -Qt4 -Tg

gswin32c -q -dNOPAUSE -dBATCH -sDEVICE=png16m -r72 -dTextAlphaBits=4 -sOutputFile=gs.png -ftest.eps

Here are the contents of the classification.txt file:
-4.25 -0.5 12 0 0 TC UNCLASSIFIED
4.25 7 12 0 0 BC UNCLASSIFIED

When I run gswin32c directly, the entire image is visible, so I have a workaround in place.

I have attached my sample output (the PNG files have been rotated manually to the correct orientation, as my application handles that automatically).

I am using (an admittedly old version) GMT 4.5.2, but I don't think it is a bug, but more so that I am doing something incorrectly when creating the file or the annotations. Is there a way to specify the BoundingBox to ps2raster?

Thanks,
Marcus

Cannot really reproduce this since 4.5.2 was some time ago. The eps stuff was yanked as we could not do a good job without full access to font metrics. So better to use more recent GMT and specify the paper size you want. You can use an exact custom papersize to impose your own boundingbox, or use ps2raster -A if you want a tight one.

So, I have upgraded to GMT 4.5.12 and switched to using PAPER_MEDIA=letter instead of letter+, producing plain PS instead of EPS. Ps2raster now converts the file correctly in my tests, however, in production, the paths have spaces in them and so ps2raster fails. Ghostscript itself has no problems dealing with spaces in the path as long as the filenames are quoted (so my current workaround still works). Would it be possible to get this added to ps2raster?

Thanks Marcus-

I guess we are prejudiced against filenames with spaces so there were no check for this in the system calls to GS and GDAL.
Fixed in r10252 (GMT4) and r13441 (GMT5).

Hi Paul,
I am unable to test the SVN version, but looking at the SVN log, I see that you are using single quotes around the filenames. I'm sure this should be fine on Linux, but on Windows, they use double quotes to quote filenames with spaces (I am on a Windows system). Do you think this will be an issue?

Thanks,
Marcus

When I run gswin32c directly, the entire image is visible, so I have a workaround in place.
I have attached my sample output (the PNG files have been rotated manually to the correct orientation, as my application handles that automatically).
I am using (an admittedly old version) GMT 4.5.2, but I don't think it is a bug, but more so that I am doing something incorrectly when creating the file or the annotations. Is there a way to specify the BoundingBox to ps2raster?
Thanks,
Marcus

Hi Paul,
I am unable to test the SVN version, but looking at the SVN log, I see that you are using single quotes around the filenames. I'm sure this should be fine on Linux, but on Windows, they use double quotes to quote filenames with spaces (I am on a Windows system). Do you think this will be an issue?
Thanks,
Marcus

Thanks Marcus-
I guess we are prejudiced against filenames with spaces so there were no check for this in the system calls to GS and GDAL.
Fixed in r10252 (GMT4) and r13441 (GMT5).

So, I have upgraded to GMT 4.5.12 and switched to using PAPER_MEDIA=letter instead of letter+, producing plain PS instead of EPS. Ps2raster now converts the file correctly in my tests, however, in production, the paths have spaces in them and so ps2raster fails. Ghostscript itself has no problems dealing with spaces in the path as long as the filenames are quoted (so my current workaround still works). Would it be possible to get this added to ps2raster?

Cannot really reproduce this since 4.5.2 was some time ago. The eps stuff was yanked as we could not do a good job without full access to font metrics. So better to use more recent GMT and specify the paper size you want. You can use an exact custom papersize to impose your own boundingbox, or use ps2raster -A if you want a tight one.

Hello,
I am programmatically generating an EPS file using GMT, and then converting it to PNG using ghostscript. However, when I use ps2raster, part of the file gets cut off.
I have reduced my "script" to a pretty minimal example that demonstrates my issue. The size of the image is supposed to represent a letter-size (8.5"x11") sheet of paper, with "UNCLASSIFIED" printed in the top right and bottom left corners (in the production map, there are additional annotations on the page as well). After running ps2raster, the "UNCLASSIFIED" at the top of the image gets cut off, and the margin on the right side of the map is now smaller.
pscoast -R-180.0/180.0/-60.0/90.0 -B30g15/30g15

When I run gswin32c directly, the entire image is visible, so I have a workaround in place.
