Example:
Create a one sheet landscape PDF from Excel. Open it using Adobe Reader, where it opens as landscape. Print it using Ghostscript. Open printout using Adobe Reader, and it should still be landscape, but it isn't.
This issues happens whether or not the source is a PDF or Excel itself. I use a PDF source in the example because I figured that it would be easier to illustrate the issue.
I know it can probably be forced to be printed using landscape. What I don't understand is why Ghostscript is not using the orientation of the original document. How can I get Ghostscript to keep the orientation of the original document?

You've left the AutoRotatePages switch at the default. The default is to rotate pages so that the majority of text is horizontal, if you don't want that, then set -dAutoRotatePages=/None.
Since you apparently already have a PDF file ? Why use Ghostscript to create another one ? You stand the chance of losing stuff that way.
Since the input is PDF there is no point in the -sPAPERSIZE switch, since that only sets the dfefault media, which is immediately overridden by the PDF interpreter.
If I were you I wouldn't set -dPDFSETTINGS at all, nor -r300 (the resolution setting is mostly pointless for pdfwrite)

I have a .ps document with 2 pages.
The first page is portrait mode and the second is a landscape mode.
I use ghostscript 9.18 :
gs -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sOutputFile=./test.pdf test.ps
My PDF have a correct first page to portrait mode and my second page is also in portrait mode but it is cut, I lose content !!!!
How to make my second page stay in landscape mode?
Thanks
EDIT :
I did the test with a single page in my .ps file in landscape mode and I have the same problem, the page is cut off.
Accuracy, my .ps file does not contain text, it's an image
Without seeing your input file its impossible to tell for certain, but if you read the Ghostscript documentation in VectorDevices.htm you will find the AutoRotatePages switch, you probably want to change that.
If that doesn't help then you're going to have to share the file.
Other than that, you are using an old version of Ghostscript and should upgrade.
I am analyzing a model (compiled with -pg option so it would generate "gmon.out") and then generated a PS file (using gprof2dot.py and piping that to "dot") that charts how much time is spent in each subroutine. When I use ghostscript to convert to a PDF it is cutting off some of the right hand side of the figure. So I tested outputting to multiple pages, but the first page still has the right side cut off and the second page is blank.
These are the 2 commands I have tried:
gs -dBATCH -dNOPAUSE -dPDFFitPage -sOutputFile=myfile.pdf -sDEVICE=pdfwrite output.ps
gs -dBATCH -dNOPAUSE -dPDFFitPage -sOutputFile=out%d.pdf -sDEVICE=pdfwrite output.ps
Please let me know if you have any suggestions. Thanks!
Your title says you want a PNG (and you render a PostScript program to PNG, not "convert a PostScript image", PostScript is a programming language not an image format) but your description says you are creating PDF files. So which is it, PNG or PDF ?
Using PDFFitPage scales the requested media size to fit an actual (already set up, fixed) media size, since you haven't set a fixed media size on the command line, no scaling will be performed.
So, what media size are you getting, and why is that not correct ? I would 'guess' that your PostScript program does not request a media size, if it did then pdfwrite would create a PDF with the same media size.
In the absence of a media request, the pdfwrite device uses the default. Depending on your system and configuration that will most likely be either A4 or US Letter. It then reproduces the PostScript drawing program by either rendering to a bitmap, or as a PDF page description, using that media size. If the original PostScript required a different media size, then bits will be clipped.
Since you have not supplied an example its not possible for me to do more than guess of course.
However, you should probably try setting -sPAPERSIZE to something like A3. Or set a specific media size using -dDEVICEWIDTHPOINTS and -dDEVICEHEIGHTPOINTS.
If you supplied an example I could probably be more specific.
It would also be a decent idea to mention what version of Ghostscript you are using too.
I have to convert pdf files (created with jasperreports) to postscript.
I'm using ghostscript (Version 9.19) to make the conversion.
The commmand i'm using is:
gswin64c -dNOPAUSE -dBATCH -sDEVICE=ps2write -sOutputFile=file.ps file.pdf
The conversion is done without problem, but when i open the postscript file generated (using GSview 5.0), the top margin is crop by 2-3 cm, and some information to print is lost.
I have changed the device from ps2write to eps2write, used the property -g<width>x<height> with the page size in pixels, but the problem persist.
The file is to be printed in a preformated paper, so i can not use the postscript generated to print.
Can someone help?
Thanks
Its not possible to say with great certainty, but it sounds like the PDF mediaBox is larger than the media you have specified to GSView.
You can try using the -dDEVICEWIDTHPOINTS and -dDEVICEHEIGHTPOINTS along with -dFIXEDMEDIA and -dPDFFitPage, that should allow you to set up a specific media size, override the size in the PDF file and scale the result to fit the specified size.
Perhaps you could post an example PDF file, without that its very hard to comment sensibly.
Is there an option to print a pdf in ghostscript as images?
I can use:
gs -dNOPAUSE -dBATCH -sDEVICE=pngalpha -r300 -sOutputFile=p%03d.png my.pdf
Then use imagemagick to make a pdf out of them with:
convert *.png new.pdf
PDF printers seem to have an option that does the same thing that is a checkbox that says "print as image". I could not find anything in the ghostscript docs that sounded like that was an option. There may be a term for it that I just don't know to look for.
It is kind of hard to explain why you would want to take a pdf document that is text and turn it into a document of images of text that is 4 times the size of the original but that is what I want to do.
Currently the only way to do that would be to start with a PDF which contains transparency operations, and select a CompatibilityLevel of 1.3 or less.
I have an idea to implement this feature, but I have not had time to work on it.
You can do it as a 2-pass approach using Ghostscript to render an image, then using the view* scripts to read the image back into Ghostscript and produce a PDF. No better than using convert of course.
I'm trying to use ghostscript to convert a .ps file to a series of .png files, largely because I don't have a tolerable ps viewer.
This is the command I've used:
gs -dBATCH -dEPSCrop -dEPSFitPage -sDEVICE=png16m -r300 -dNOPAUSE -sOutputFile=neptune_111115_ob1-2_13pca_boloplots_%d.png neptune_111115_ob1-2_13pca_boloplots.ps
(the .ps file is a multi-page postscript).
The outputs are partly off the page. I'd like the images to fit inside the page.
I can include example files, but they're pretty large - is there any particular part of the .ps file that would be helpful?
My suspicion is that the .ps file is specifying the bounding box incorrectly, but hacking the BB values didn't have any effect. The .ps file is written by IDL (ittvis' Interactive Data Language). I've also tried the above command without the -dEPS* commands without luck.
-dEPSCrop and -dEPSFitPage are mutually exclusive:
One crops the EPS to the BoundingBox specified in the comments.
The other scales up the EPS from the %%BoundingBox specified in the PS file's internal comments to fit the current media.
You can't really use both at the same time.
The file can't be an EPS file anyway, because you can't have multiple pages in an EPS file. So actually neither switch will have any effect (as you've discovered).
Either the PostScript requests a media size using setpage or setpagedevice, or it just uses whatever the currently set media is. My guess is that its just using the current media. Try setting -sPAPERSIZE=a4 and -sPAPERSIZE=letter.
If that works then the program does not request a media size. If it has no effect, then set -dFIXEDMEDIA in addition which will ignore subsequent requests to change the media size.
That should allow you to specify the correct media size, if you don't know what the media size should be then you can use the Ghostscript -sDEVICE=bbox device to find out.
Lastly, Ghostscript has a rudimentary display device which you can use to view the rendered output without first going to a PNG.
