PostScript

My custom application generates Postscript files that are then distilled to create a PDF file as final output.I know how to program a watermark in Postscript using setpagedevice.However, I cannot find a way to dynamically make the watermark appear only at printing time. I'd like to emulate (programmatically in PS, or pdfmark)  the Acrobat Professional capability whereas you can set a watermark to appear only at printing time.Thanks for your suggestions!

Hi,I was wondering if it's possible in PS to set colorspace to both RGB plus LAB coded? Not either of the two but both.Thanks!

I recently switched to a new Intel-base iMac. It has OS 10.4.11, adobe CS3, and Suitcase Fusion. My problem is my intel-base iMac read all Postscript fonts as TEXT DOCUMENT! I ran the Font Doctor and all the fonts are good; both screen fonts & printer fonts are in the same folder. The font folder is stored in the network server where my colleagues can share. They have no problems reading it. The only differences are my colleagues use Power G4 Mac with OS 10.4.10 and I use intel-base iMac with 10.4.11. I asked Extensis for tech support and the answer I got was to make sure to run the Font Doctor and have both postscript fonts in the same folder. Then, I called Apple support and they told me to have a intel-base/universal version of font manager which might solve the problem. But I already have a universal version of Suitcase Fusion! And problem still there. Does anyone have this problem? Please help! thanks in advance

Can anyone provide me with a PostScript file that shows all the dictionaries and/or resources that are necessary to download a CID font into a PostScript printer?I've read all the documents I can find about it. Of course, there's not much written about PostScript anymore - everything is about PDF now.I've seen the Type 42 example for a single-byte font but that doesn't apply at all to double-byte fonts.  They have to be downloaded as CID fonts.A file that downloads a single glyph used for a character greater than 255 would do the job.There seems to be no example for a CID font out there.Allan.

Hi,I am new to this but i have been creating a PPD to be used in my office to set defaults for a postscript file so i can make a PDF from it.I am trying to set the true type font options to download as softfont.Is there any way to do this in the PPD???? I know how to change the setting in advance printer settings but that defeats the purpose of creating a PPD for us.please helpthanks

When generating a PDF file I preceed text with something like:  "0.46 w 2 Tr" in order to make text in a normal font look bold.It works just fine in a PDF file but I would like to be able to do the same thing in a PostScript file. Is there any operator or construct of any sort in PostScript that will accomplish this?Thanks,    Allan.

Hi everybody,I am looking for a detailed information about apostsript stack functioning,  what commands exactly are puton the stack and how one can control the stack sizewhen creating postscript files. We are writing a postscriptdriver and our postscripts often shows stack overflowerrors, but we did not find any sufficient information abouthow to avoid this problem in neither ps books.Does a stack size depends on a particular PS interpreteror are there any standards? What is a typical stack size?What is the best way for developer to follow the stack size,so that it does not get overflowed?Thank you very much in advance for any help,Yuliana

Thank you everyone for the answers to my previous post. Another Postscript problem which we are now trying to solve,is the following printer behaviour:  getting our postscript datastream, printer first goes through the whole document,ripping every page (or so it seems) and only then it starts printing the first page and further. Our datastreams are usuallylarge, tens thousandth of pages, so it takes very long before a printer starts to print. What could cause such a behaviour?Something at the end of the file, which interpreter needs to take into account? Some special settings at prologue?Thank you in advance for your help,Yuliana

Hi All,I am sending a Poscript print file to an HP4650 printer which has a built in duplexer. I need the file to print duplex, but, turning duplex "on"  at the printer is not an option as we also print simplex documents on it. My file also has a "mediatype" call to pull perf paper. I've checked the .PPD file for the printer and found the command structure for duplex and for the mediatype commands. If I use the duplex command by itself, the file duplexes. If I use the mediatype by itself, the the file pulls the perf paper. If I use the two commands together in the file, it pulls the perf, but prints simplex, not duplex. Here are the commands I'm using - they are located in the %%BeginSetup section which is immediately following the %%EndProlog and is prior to the actual print data in the file. Can anyone tell me why the two commands won't work together or how to coorect my code? Thanks!featurebegin{%%BeginFeature: *Duplex DuplexNoTumble  <</Duplex true /Tumble false>&

I am attempting to create a workflow through which non-Adobe Windows XP users can create EPSs from MS Excel charts and graphs. I'm successful doing this with the Adobe Generic PostScript Driver *except* that the BoundingBox is the size of a letter when I bring the resulting EPS into InDesign. Is there a way to edit the BoundingBox out using a basic text editor? Or, is there a way to set the bounding box to be the same size of the chart? It would be great is there was a simple process that I could communicate to non graphics people.

Is it possible to specify apha values (transparency) for stroke and fill colors in PostScript?

First pardon me as I do not know if I posted in right forum.My problem is sometimes when I print a PDF 1.3 file to PS level 2 RIP, I am receiving an error "increase MaxDisplayList or MaxSourceList" and cpsi error code '12'. Anyone knows what is the meaning of this? The PDF file is a simple layout in grayscale exported from Indy CS3. All text are converted into curves and completely flattened. I'd printed a much complex PDF 1.3 colored page into the RIP without problem but occasionally I was prompted by this problem in simple PDF 1.3 file. Anyone knows?Thanks.

Hello,I have a simple question, that I am having trouble finding a simple answer for: Can an EPS file be used as a background image in a PostScript program?Here is some background (no pun intended):  I have a standard Letter sized .jpg image that I have converted to an .eps file.  (I've tried using both GIMP and Image-Magick for this).  I then try to call in the eps into my postscript program, expecting it to act as a background image, allowing my variable data to print over the top of the .eps file.  This is not happening.  Instead, the .eps file covers up all my data.I've tried changing the order of when I call in the .eps file, but that doesn't seem to make a difference here.  I've also looked briefly at clipping limits, but even if it did work, it does not apply since the .eps uses different shades of gray, all of which need to be over-printed.  Creating the graphics on the fly in regular PostScript is not an option either, as the graphics are too

I have a postscript file made from a printer driver. Is there any way we can distinguish between color and b/w pages, i.e to get count of number of colored and B/W pages in the postscript file.I found on inet that postscript operators setrgbcolor and setcmykcolor give color information but i wasn't able to find operators setrgbcolor and setcmykcolor in my postscript file.

Hi, I have an EPS file with a single Polygon object in it, i want to change the fill color of that object. Not in any designer, but programmatically (Microsoft .NET), because i will then use the resulted EPS somewhere else. I tried a component, but it resulted in a raster EPS, that ofcourse, i dont want. Does anyone know how do i do it? Thanks

hi! i'm dealing with matrices here and want to plot its value into postscript. in fact, i just need a black spot where a matrix entry is not zero, white everywhere else. easy, isn't it? particulary, my matrices have very few non-zero entries, so the ps file would only have a few black spots here and there. now, what's the best way to write this in postscript? the first thing i tried was the image environment: works well as soon as you got used to the syntax, but the big disadvantage for me was that i have to explicitly code all the white pixels, so the eps file gets a lot bigger than needed (it feels). the second thing i tried was defining a small "draw tiny box" command, then "move to" the non-zero spots, and evoke the function. that's better then the image way (the files are a lot smaller), but it still feels like a hack somehow. do you have any hints or suggestions for the issue? are there any commands or environment that would be better suited? all hints appreciated! cheers,

I want to write a programe,and extract text and image information from postscript file using Java.Is it possible? How to extract ? Thank!

Is there a way to code the line so it will center on the page without my recalculating the values (161.88 is the horizontal position of the moveto obviously) This particular line was origionally generated with Quark 3 and I use some moveto operators similar to this in my application. The vertical must be 410.05 as this text is 'envelope' sensitive. 161.88 410.05 m .5 5 24 175.25 (Certificate of Coverage)d Thanks TGW

For our newspaper paste-ups we need 65 line screen halftones for good reproduction. The newspaper printing plant doesn't yet have digital to film or plate. We still give them paste-ups output from a paper printer that they use a process camera to make negs from. At one time I could rely on Postscript printers to provide the linescreens I wanted. But my recently purchased Xerox Phaser 6130 lacks this ability. For my uses the present-day Postscript printers seem vastly inferior to the Postscript printers of 10 years ago. Is there still an affordable Postscript printer on the market that can meet my needs?

Hi, I'm converting html to ps, but it produces a solid white background color. how should I change the ps file so the page background will be transparent after converted to image?

Does anyone know what code I would need to include in a .ps file in order to center the page horizontally on the paper on output? If so, what is it? I'm going crazy here!

Hi, We have so many programs written in Post script by previous developers,10 years ago.right now we are trying to understand what is been written in those programs and trying to reengineer them with latest programming language. in that process our big hurdle is understanding the existing code.because we have no post script knowledge at all . i would like to hear from anybody who can help me in guiding what my best bets would be, either to learn post script language or are there any tools which can convert them to a popular language or any debugger to understand the code.

I am new to postscript. Is there a way to know original file format(pdf,jpg,doc,txt,xls) etc from the postscript file. Does postscript file have any such information about file type ?

Hi Friends, Is there any tool for developing Postscript code ? (or) Is there any IDE for Postscript ? (or) Thanks & Regards, Navaneeth Sivappan

Hi! I am kind of new in PostScrip programming (actually code generation from C) and I want to know if there are some kind of encoding of an image when you need to write what it contains in the .ps files. Can I write the bytes it contains using hexadecimal numbers or is there some kind of encoding I have to do. Thanks in advance!
