postscript

In response to a challenge in comp.lang.postscript, I'm working-up my 3D chops trying to render a cylinder as projected rectangular patches. But I'm still seeing the wire-frame even after I comment-out the line-drawing, because the patches don't butt-up flush. The cylinder is modeled along the z-axis by double-looping over z (-2 .. 2, step 4/N) and theta (0 .. 360, step 360/N). The four points of the rectangle are: v1 = (R cos T, R sin T, z) v4 = (R cos T, R sin T, z+dz) v2 = (R cos (T+dT), R sin (T+dt), z) v3 = (R cos (T+dT), R sin (T+dt), z+dz) Then we apply a model->world rotation to all

I was wondering if it is possible to get argv[0] in postscript. For example, I want to be able to print the postscript file's name. If I name the postscript file 1.ps then it will print out 1 and if I name it 2.ps it will print out 2 and so on. This is not possible with Postscript in general. Many postscript environments, like in a printer, will not have a filesystem or filenames at all. A file in the general sense is just an abstraction for accessing a sequence of bytes one at a time. The Ghostscript interpreter implements an extension which may enable you to do what you want. <file>

Is it possible to create a tiff file from a postscript-file (created from a pdf-document with readable text and images) into a tiff file without the images and only the text? Like add a maxbuffer so images will be removed and only text remaining? And if boxes and lines around text could be removed as well that would be awesome. Best regards! KenS You can redefine the various 'image' operators so that they don't do anything: /image { type /dicttype eq not { % uses up argument, only one if dict form pop pop pop pop % remove the arguments for the non-dictionary form. } ifelse } bind def

Is it possible to use itextsharp to convert postscript to a PDF ? If not is there another way to do it in .net ? Converting PostScript to PDF is called "distilling". iText and iTextSharp do not support distilling. Ghostscript will be your only FOSS solution. You could use Ghostscript as it's explained here: http://hi.baidu.com/lqyidxa_igfv/blog/item/df2037b394539fa0d9335a94.html 来源： https://stackoverflow.com/questions/4970511/itextsharp-postscript-to-pdf
