Re: [PyQt] problem running pyqt on xubuntu
Hello, I am doing it for eric development using separate Qt installation directories, Python virtual environments and start scripts setting the path to the Qt tools explicitly. Works perfectly for me. Just make sure to set the path explicitly when building PyQt4 and QScintilla stuff.

[PyQt] Exporting an image to a PDF
Hi all. I have been looking for ways to get things exported to PDF; I must say that I am pleasantly surprised by the ease of exporting a text-document to a PDF :) Googling also says that exporting an image to pdf is easier than exporting a text-documnt in PyQt; unfortunately for me, I have not been able to find the steps to do that :-\ So, I will be grateful if I could be directed to a Hello World program to do this. My requirement is very simple :: * Read an image file (png/jpeg, etc). * Export to PDF; simple. No editing of pixels, or any other stuff. Looking forward to some pointers :) Regards, Ajay ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Minimalistic example:
#--
image = QtGui.QImage(myImage.jpg)
printer = QtGui.QPrinter()
printer.setResolution(300)
printer.setOutputFormat(QtGui.QPrinter.PdfFormat)
printer.setOutputFileName(myImage.pdf)
painter = QtGui.QPainter()
painter.begin(printer)
painter.drawImage(target, image, source)
painter.end()
#
where target source are QtCore.QRectF(sheet) QtCore.QRectF(image)

Thanks a ton Vincent !!
I could get myself started with image-exporting to pdf (all courtesy
you :) )
One thing I must tell you; right now, I just got myself bootstrapped,
without truly putting the correct values in target and source.
I have two queries though ::
a)
target represents the target-canvas, of which the image will take
the size, right?
b)
If yes, then I find it a little odd, that no such target is
specified, while exporting a text-document to pdf.
For example, here is my code to export a text-document to pdf ::
from PyQt4.QtGui import *
import sys
app = QApplication(sys.argv)
text_file_path = open('sample.py').read()
doc = QTextDocument(text_file_path)
printer = QPrinter(QPrinter.HighResolution)
printer.setOutputFormat(QPrinter.PdfFormat)
printer.setOutputFileName('sample.pdf')
doc.print_(printer)
Here, we can see that no target QtCore.QRectf is passed to the
printing options.
Any idea of this descrepancy? (as to why the target canvas is
specified while exporting an image; but not when exporting a
text-document, though the target canvas size is usually fixed,
irrespective of the source mime-type).
Because in my example I've used QPainter.drawImage() and not
QTextDocument.print_().
See the doc:
http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/qpainter.html#drawImage
you can also use only the origin of the image instead of target-source,
but you'll need to handle the margin parameters of your printer.
Thanks anyways for your already rendered massive help :)
Regards,
Ajay

[PyQt] Specifying Include Directories for PyQt Build
Starting with python3.3, python will support multiarch [1] in Debian and Ubuntu. As part of this change, the path for some of the Python header files has changed, so I need to specify multiple include directories. Here's an example using pkg-config so show the difference between python3.2 and python3.3 on an i386 system: $ pkg-config --cflags-only-I python-3.2mu -I/usr/include/python3.2mu $ pkg-config --cflags-only-I python-3.3m -I/usr/include/python3.3m -I/usr/include/i386-linux-gnu/python3.3m So how do I specify both directories for building with this multi-arch'ed python3.3?

Any advice appreciated. Scott K [1] http://wiki.debian.org/Multiarch Nevermind. I think I understand the problem now. I had it half solved. Once I fixed my sip4 build, the arch specific directory was captured by sip in py_conf_inc_dir and I had correct includes for the directories configured by sip, but not for qpy. Adding the patch below to configure.py solved that by adding it to the qpy .pro files. Is this a reasonable way to handle it and would you consider this an appropriate change for upstream?
