With the above command the boundary box will be still broken (too large). The crucial option is -pta, which fixes the ugly looking font when you directly import the eps file into openofffice ( -pta sets correct inter-letter spacing). Pstoedit -pta matlab_plot.eps matlab_plot.emf emf is still a vector based format and can be imported by openoffice. Instead of png you can convert to matlab_plot.jpg.Choose a higher number than 100 to get a higher resolution of the image.Afterwards convert the pdf file into a png or jpg fileĬonvert -density 100 matlab_plot.pdf matlab_plot.png Convert Matlab eps file in a pixel graphic like png, jpg: First convert the eps file into a pdf file.Pdfnup -nup 2x2 file.pdf # 4 pages on one page Pdfnup -nup 2x1 file.pdf # 2 pages side by side Pdftops input.pdf - | psselect -p22-36 | ps2pdf - output_p22-p36.pdf Pdfjoin file1.pdf file2.pdf # alternative Pdfunite file1.pdf file2.pdf file-new.pdf Open the PDF File with an application and save it in a different format.Pdfimages -j file.pdf image # write images if possible as JPEG files Convert a PDF file to images (one image per page)Ĭonvert page 2 ( -f 2) to page 5 ( -l 5) with a resoltion of 300 dpi ( -r 300) to five PPM image files.Note: pdf2ps does also convert PDF to PS, but normally the result is worse. The resulting NETCDF file will be mygribfile.nc Convert a transparent eps (in cmyk) to a png fileĬonvert -colorspace rgb file.eps file.png.Gs -r300 -dNOPAUSE -dUseCropBox -dBATCH -sDEVICE=jpeg -sOutputFile=file.jpg file.ps # r300 = resolution of 300 dpi Gs -r300 -dNOPAUSE -dUseCropBox -dBATCH -sDEVICE=pngalpha -sOutputFile=file.png file.ps # r300 = resolution of 300 dpi Ps2pdf -sPAPERSIZE=a4 -dOptimize=true -dEmbedAllFonts=true file.ps Just try out which tool produces the best results in your case. There is normally more than one way to convert files. The command convert can convert between several formats and has a lot of options, see man convertĬonvert -resize 50% file.jpg file_small.jpgĬonvert -resize 200x200 file.jpg file_small.jpg # ratio will be keptĬonvert -resize 1024x768! file.jpg file_desktop.jpg # ! = force the new sizeĬonvert between Windows/Mac and Linux text filesĬonvert text files between different character encodings Convert text files between different character encodings.Convert between Windows/Mac and Linux text files.I referred Adobe's Postscript Language Reference to understand the operator setrgbcolor and operands that it accepted. I got a jumpstart from youtuber "John's Basement" in the video series Postscript Tutorial. PS2: I was a total stranger to Postscript coding. PS1: The above code was implemented in windows command prompt Thus 0 0 0 is passed to the operator osetrgbcolor custom defined earlier Now define a new instance setrgbcolor that pops the 3 inputs expected by original setrgbcolor and replace them with 0 0 0 i.e. It tells to bind the original definition of setrgbcolor with a new custom operator called osetrgbcolor. What I understand is that code in quotes following -c switch is postscript. So I decided to play with other operators that can set colour is postscript like setgray, setrgbcolor, setcmykcolor, etc. I did not have any success with setcolor operator as suggested by Surge. Step 2: Convert the coloured.ps to blackandwhite.pdf gswin64c ^ Step 1: Convert the coloured.pdf to coloured.ps gswin64c -dNOPAUSE -dBATCH -sDEVICE=ps2write -sOutputFile=coloured.ps coloured.pdf I had to modify the solution suggested by Surge ( above) a little bit for my file: ![]()
