| bman_ | hello | 00:05.00 |
| ghostbot | Welcome to #ghostscript, the channel for Ghostscript and MuPDF. If you have a question, please ask it, don't ask to ask it. Do be prepared to wait for a reply as devs will check the logs and reply when they come on line. | 00:05.00 |
| bman_ | I just downloaded gsview. Which dll exports a file to pdf? If I wanted to use gsview through it's API, how would I send gsview a file and have it export it to a PDF file without opening gsview? | 00:06.26 |
| npnth | I've got a lot of DjVu files, and I'd really prefer to use MuPDF's interface to read them. Has anyone tried to add DjVu support to MuPDF before? | 05:09.26 |
| cryptopsy | can i make a pdf from 25 .png's ? make one pdf, like how the binary 'convert' can do | 13:28.31 |
| | for example convert *.png out.pdf | 13:33.03 |
| | doesn't seem gs can take png as input | 13:37.57 |
| | how can i make the output pdf have the same size format as the input images, which are all the same size? | 13:43.52 |
| kens | cryptopsy : Ghostscript only reads PostScript and PDF. However you can write a program in PostScript to read other file formats. If you look in /ghostpdl/lib you'll find a numebr of programs named view*.ps, these read teh named file formats. However, there's no PNG variant. | 14:54.51 |
| | Regarding the output size, you need to send a Media Size request. If you know the media size then the PostScript is: | 14:55.14 |
| | <</MediaSize [width height]>> setpagedevice | 14:55.34 |
| | Where4 width and height are the dimensions in PostScript units (points) 1/72 inch | 14:55.53 |
| | Of course, you also need to scale the images to fit on the media. Usually the view* programs render the images 1:1. That is, each image sample corresponds to one output pixel. So the media size you want needs to take into account the resolution you are rendering at. Its probably easiest to set the resolution to 72 dpi (-r72) | 14:57.19 |
| | bman_ for the logs... You need to specify which version of GSView | 14:57.54 |
| | Also, none of the DLLs exactly 'exportsa file to PDF'. | 14:58.18 |
| | I don't believe that any version of GSView currebtly can be run without a user interface. | 14:58.54 |
