printing

问题 I am generating reports in HTML formats, and want to print them automatically using Qt (qt has a webkit based browser, and one can render its contents to a PDF file). I want to position the elements of the report depending on the target page size. For that i need to access the size of the paper (preferably in pixels). Since i am using webkit, it has all the latest html5 and css3 features. is there some api available to access printed page properties inside javascript. for example, would be

问题 I learned how to redefine the Lua's print() in C++ from this post. (https://stackoverflow.com/a/4514193/5224286) Here's the redefined print function that prints variables to my host program's console. (through the functions named post.. ) int l_my_print(lua_State *L) { int nargs = lua_gettop(L); for (int i = 1; i <= nargs; ++i) { if (lua_isnil(L, i)) poststring("nil"); else if (lua_isboolean(L, i)) lua_toboolean(L, i) ? poststring("true") : poststring("false"); else if (lua_isnumber(L, i))

问题 I looked for how to dump and array to the console I have mostly found: for (id name in arrayStuff) NSLog (@"Array contents: %d", name); I've tried different formaters %d %@ %g etc. which does print different stuff, but not the values I'm 99% sure are being entered into the object and consequently the array. This doesn't seem to work, how would you know what to use as the formater? I have an NSMutableArray with instance of an object containing one int and two doubles added to the array in each

问题 I'm working on a project that is involving converting PDF handbooks to html. I am trying to retain the value of a PDF when printed, while giving them a better ui on devices which aren't bound by the concept of pages. The issue that I am running into is that these handbooks have a Table of Contents with the page number of where each chapter/section begins. When viewing on a device, that list will just be in-page anchor links, but when printing I would like to get the page number of an element

问题 Is there no standard way to print out values for end-user consumption? Show is clearly more of a debugging convenience than something that would work for this purpose, given the conventions around its use and the constraint that read (show x) == x . For example, isn't there at least a simple package like class (Show a) => PShow a where pshow :: a -> String pshow = show pprint :: (PShow a) => a -> IO () pprint = putStrLn . pshow where instances do something like instance PShow MyType where

问题 I'm trying to add printing support to a C# WPF application I'm writing and I'm tearing my hair out over this. I'm trying to print a single image from a window in a WPF application. The image is a shipping label and the printer is a thermal printer loaded with 4"x6" shipping label stock. The code to print is as follows: PrintDialog pd = new PrintDialog(); if (pd.ShowDialog() == true) { Image tmpImage = new Image(); tmpImage.Stretch = Stretch.Uniform; tmpImage.Width = pd.PrintableAreaWidth;

问题 I need some help with tweaking my PDF header/footer alongside my text areas. The first page looks okay and it just gets worse from there. Is the header and footer eating into my existing margin spaces? I would like to know what is going wrong and what I can tweak to set the below: Page widths Margin widths Header Footer Text area My header override function is as below: public partial class Header : PdfPageEventHelper { public override void OnStartPage(PdfWriter writer, Document doc) {

问题 I am allowing my users to print but the output is way too large (I have to manually adjust to about 60% in the print dialog). I use a css media query (below) to control the content and have tried changing the font-size of the html, body{} without any change to the output font size. Printing to Adobe PDF prints correctly Any ideas what I am doing wrong? My Print Link: <a href="#" onclick="window.print(); return false;"></a> My css: @media print { body * { visibility: hidden; } .printme,

问题 this is my very simple code, printing argvs: import sys argv=sys.argv for each in sys.argv: print each here's the output when ran: e:\python>python test1.py 1 2 3 4 5 test1.py 1 2 3 4 5 I want it to be compiled, so I made one with py2exe: e:\python>python setup.py py2exe and my setup.py: from distutils.core import setup import py2exe, sys, os sys.argv.append('py2exe') setup( options = {'py2exe': {'bundle_files': 3}}, windows = [{'script': "test1.py"}], zipfile = None, ) and I don't get any
