Just to make sure I wasn't crazy, I checked it: PM> Install-Package Ghostscript.NET 'Ghostscript.NET 1.2.0' already installed. Project already has a reference to 'Ghostscript.NET 1.2.0'. PM> The project is used by multiple developers. It targets Any CPU, and needs to remain that way.

I am working on Python 3 Thanks for help guys, (oh, and I'm French, so maybe my English is not really perfect !) 回答1: In case someone

According to this question: Displaying PDF documents on iPad - Color Problems some PDFs don't display right on iOS devices due to colors not being in RGB. It's also mentioned that converting PDFs from CMYK to RGB could be automated using ghostscript. Anyone know how the actual command might look like? Codo We use Ghostscript to convert from CMYK to RGB when generating PDFs from Postscript files. It should also work for PDF-to-PDF conversions. The followind command line is used: gs -sDEVICE=pdfwrite -dBATCH -dNOPAUSE -dCompatibilityLevel=1.4 -dColorConversionStrategy=/sRGB -dProcessColorModel=

I have a scanned pdf file and I try to extract text from it. I tried to use pypdfocr to make ocr on it but I have error: "could not found ghostscript in the usual place" After searching I found this solution Linking Ghostscript to pypdfocr in Windows Platform and I tried to download GhostScript and put it in environment variable but it still has the same error. How can I searh text in my scanned pdf file using python? Thanks. Edit : here is my code sample: import os import sys import re import json import shutil import glob from pypdfocr import pypdfocr_gs from pypdfocr import pypdfocr

My stomach churns when I see this kind of output. http://www.freeimagehosting.net/uploads/e1097a5a10.jpg and this was my command as suggested by Best way to convert pdf files to tiff files gswin32c.exe -q -dNOPAUSE -sDEVICE=tiffg4 -sOutputFile=a.tif a.pdf -c quit What am I doing wrong? (commercial products will not be considered) tiffg4 is a black&white output device. You should use tiff24nc or tiff12nc as the output device colour PDFs - see ghostscript output devices . These will be uncompressed but you could put the resulting TIFFs through imagemagick or similar to resave as compressed TIFF.

I've been bashing my head against this to no avail. I need to shrink some large PDFs to print on an 8.5x11 inch (standard letter) page. Can ImageMagick/Ghostscript handle this sort of thing, or am I having so much trouble because I'm using the wrong tool for the job? Just relying on the 'shrink to page' option in client-side print dialogs is not an option, as we'd like for this to be easy-to-use for the end users. The problem with using ImageMagick is that you are converting to a raster image format, increasing file size and decreasing quality for any vector elements on your pages. Multivalent

Linux下通用打印系统CUPS使用教程 2018-06-14 15:36:34 Nerror 阅读数 576 https://www.cnblogs.com/chjbbs/p/6536332.html 1.什么是CUPS CUPS(Common UNIX Printing System，即通用Unix打印系统)是FedoraCore3中支持的打印系统，它主要是使用IPP(Internet PrintingProtocol)来管理打印工作及队列，但同时也支持”LPD”(Line Printer Daemon)和”SMB”(ServerMessage Block)以及Socket等通信协议。 在Unix/Linux发展之初，打印总是会受到各种各样的限制，最初的打印都是用LPD(命令行方式的打印守护程序）来实现的，它不支持IPP（Internet打印协议），而且也不支持同时使用多个打印设备。而CUPS的出现，提供了一套完整的管理打印设备、实现可靠打印、网络打印的一套完整方案。此外，在Linux下进行CUPS驱动开发是遵循GPL协议规定的，也就是说必须开源。 CUPS实际上是一个集成的服务。包括了前端接收打印命令的相关程序，后端控制打印机硬件的程序，中间则是打印驱动。首先来看看CUPS驱动打印机的方式。当CUPS接受到打印命令时，首先会进行一个格式的预转换，比如将
