Printing RTF file under win32
I'm using Python 2.6.5 on win32. I would like to print a batch of RTF files on a printer. I don't want to use the win32api.ShellExecute command because that invokes Word, and Word has been configured in a strange way by one of our admins, making it inconvenient to use. What should I do? -- http://mail.python.org/mailman/listinfo/python-list

[issue6832] Outputting unicode crushes when printing to file on Linux
Jerzy jer...@genesilico.pl added the comment: OK, I give up. The problem is that one might test a program on terminal and think that everything is running OK and then spend a reasonable amount of time trying to find the problem later Another approach: couldn't utf8 be set as default encoding for all inputs and outputs? I know that some of my questions are caused by the fact that I do not understand how python works. But You have to bear in mind that most of the people don't. Such behaviour of Python (see also http://bugs.python.org/issue5092) is illogical in the common sense for standard poeple.

Hi all, I have a numpy.array of 89x512x512 uint8's, set up with code like this: data=numpy.array([],dtype=uint8) data.resize((89,512,512)) # Data filled in about 4 seconds from 89 image slices snip lots of processing code I first tried writing this data to a binary raw format (for use in a program called Drishti) as follows: # The slow bit: volumeFile=file(/tmp/test.raw,wb) for z in xrange(Z): for y in xrange(Y): for x in xrange(X): volumeFile.write(%c %(data[z,y,x])) volumeFile.close() That took about 39 seconds. My second attempt was as follows: volumeFile = open(/tmp/test2.raw,wb) data.resize((X*Y*Z)) # Flatten the array for i in data: volumeFile.write(%c %i) data.resize((Z,Y,X)) volumeFile.close() This took 32 seconds. (For those of you unfamiliar with numpy, the data.resize() operations take negligible amounts of time, all it does is allow the data to be accessed differently.)

I think I may have confused you by mentioning Qt 4. Since you are using QSimpleRichText, you must be using Qt 3, so you should probably ignore what I said about the /usr/share/doc/qt-4.1.1/demos/textedit demo. :-/ Is there any tool out there with which I can write those special HTML files? I am quite familiar with HTML and CSS but I don't want to waste my time with that. You don't need to include all those style attributes in the HTML. Anyway, that's a different version of Qt to the one you are using, so you can safely ignore it. You should probably look at the text drawing part of the demo included in Qt 3 (examples/demo/textdrawing) and see how printing is done for the rich text editor there (in the TextEdit::filePrint() function). Translating it to Python _shouldn't_ be a problem. I hope I didn't confuse you too much by talking about two different versions of Qt at the same time. Let us know how it goes.

Re: Printing a file
Sorry about that. I must have just skipped over the setup() call in your code. If you're creating highly customized content then I think you'll always need to think about getting the pages to the printer in the right order. For rich text documents, there's code that does this in the Qt 3 text drawing demo (see the filePrint() method in the examples/demo/textdrawing/textedit.cpp file). In Qt 4, the demos/textedit demo does this with a lot less code. Or are you think of something else? David -- http://mail.python.org/mailman/listinfo/python-list

Isn't there any other possibility? How do I get these values? That depends on what kind of text you're drawing (paragraphs of text vs. simple labels). See the application.py example in the examples3 directory of the PyQt3 distribution for code that implements a simple text editor with support for printing. Information about text and font metrics can be found with the QFontMetrics class: http://doc.trolltech.com/3.3/qfontmetrics.html PyQt4 supports Qt 4's new rich text facilities, so it's easier to format text for printing than it is in Qt 3. A more advanced rich text editor is only available in the C++ Qt 4 demos, but there are other examples bundled with PyQt4 that show how to print simple documents: http://www.riverbankcomputing.co.uk/ Finally, it's worth pointing out that there's a higher concentration of people with experience in these matters reading the PyQt/PyKDE mailing list: http://mats.imk.fraunhofer.de/mailman/listinfo/pykde Good luck with your printing, David -- http://mail.python.org/mailman/listinfo/python-list
