Using javascript to print images

由 好久不见. 提交于 2019-12-17 10:37:24
问题 I would like to know if it's possible to use javascript to open a popup window containing an image, and at the same time have the print dialog show. Once someone clicks on print, the popup closes. Is this easily attainable? 回答1: popup = window.open(); popup.document.write("imagehtml"); popup.focus(); //required for IE popup.print(); 回答2: Another great solution!! All credit goes to Codescratcher <script> function ImagetoPrint(source) { return "<html><head><scri"+"pt>function step1(){\n" +

问题 I want to create a virtual printer driver for Windows. How and where can I start properly? The WDK has some printing drivers examples that do not seems a good introductory. MSDN also doesn't seems to be very helpful for a novice. There are a lot of virtual printers for Windows out there (mostly they generate PDFs), I wonder if someone could tell my how can I do the same?

redirect prints to log file

由 懵懂的女人 提交于 2019-12-17 10:17:17
问题 Okay. I have completed my first python program.It has around 1000 lines of code. During development I placed plenty of print statements before running a command using os.system() say something like, print "running command",cmd os.system(cmd) Now I have completed the program. I thought about commenting them but redirecting all these unnecessary print (i can't remove all print statements - since some provide useful info for user) into a log file will be more useful? Any tricks or tips. 回答1:

How to set the plot in matlab to a specific size?

由 橙三吉。 提交于 2019-12-17 09:42:11
问题 Generally, I wish to plot a rather complex x-y plot (lots of overlapping curves) to an A3 format so: A4 210x297 A3 = A4*2 = 420 x 297 ... - 10mm each side = 400 x 277 (size of desired plot window) What is the easiest way to set the size of the plot so it fits that size when printed in PDF (or any other common output format)? 回答1: See the matlab documentation for figure properties. Namely: PaperSize - Explicitly defines the size of the canvas. PaperType - Sets PaperSize to one of several

问题 Is there any way in Java to print to a specific IPP printer? All of the sample code and tutorials I've found focus on how to print a particular type of document, using something like the following: DocFlavor flavor = DocFlavor.INPUT_STREAM.POSTSCRIPT; PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet(); aset.add(MediaSizeName.ISO_A4); PrintService[] pservices = PrintServiceLookup.lookupPrintServices(flavor, aset); if (pservices.length > 0) { DocPrintJob pj = pservices[0]

C++ format macro / inline ostringstream

由 你离开我真会死。 提交于 2019-12-17 08:53:33
问题 I'm trying to write a macro that would allow me to do something like: FORMAT(a << "b" << c << d) , and the result would be a string -- the same as creating an ostringstream, inserting a...d , and returning .str() . Something like: string f(){ ostringstream o; o << a << "b" << c << d; return o.str() } Essentially, FORMAT(a << "b" << c << d) == f() . First, I tried: 1: #define FORMAT(items) \ ((std::ostringstream&)(std::ostringstream() << items)).str() If the very first item is a C string (

How do I change the string representation of a Python class? [duplicate]

问题 This question already has answers here : How to print instances of a class using print()? (9 answers) Closed last year . In Java, I can override the toString() method of my class. Then Java's print function prints the string representation of the object defined by its toString() . Is there a Python equivalent to Java's toString() ? For example, I have a PlayCard class.
