Trying to get this code working: import cairosvg import os path = "D:/PyProjects/Bla/Temp" os.chdir(path) cairosvg.svg2pdf(url='Pic.svg', write_to='image.pdf') but get errors along similar to this post : Traceback (most recent call last): File "D:/work/lean_python/pdf/other.py", line 2, in <module> import cairosvg File "D:\env_python352\lib\site-packages\cairosvg\__init__.py", line 29, in <module> from . import surface File "D:\env_python352\lib\site-packages\cairosvg\surface.py", line 24, in <module> import cairocffi as cairo File "D:\env_python352\lib\site-packages\cairocffi\__init__.py",

I wish to render text with transparent/translucent background (or no background) over other gtk widgets like GtkImage or GtkButton etc. Primary goal is to have text display over Gtk Widgets (esp. GtkImage) in the background. I can render text on GtkFrame using pangocairo library but I am not able to get rid of the background of GtkFrame. I have seen examples of making GtkWindow transparent or translucent but I wish to have opaque GtkWindow with GtkLayout for placing the GtkWidgets, then place GtkImage over the layout and render Text on top of GtkImage so that it gives a nice background to my

I want to load a SVG file with the Cairo library, do apply some transformations to it. Then I want to display my svg with a glTexture. But I just find functions which create svg file and not load svg. Uli Schlachter Cairo itself cannot read SVG files. You need something like librsvg to render SVGs to a Cairo surface. From a quick look at their API documentation , it looks like you need rsvg_handle_new_from_file() to load a file and something like rsvg_handle_render_cairo() or rsvg_handle_get_pixbuf() to draw the SVG to a Cairo context / to turn the SVG into a GdkPixbuf. 来源： https:/

I have code which generates a Cairo ImageSurface , and I expose it like so: def preview(...): surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, width, height) ... cherrypy.response.headers['Content-Type'] = "image/png" return surface.get_data() preview.exposed = True This doesn't work (browsers report that the image has errors). I've tested that surface.write_to_png('test.png') works, but I'm not sure what to dump the data into to return it. I'm guessing some file-like object? According to the pycairo documentation , get_data() returns a buffer. I've also now tried: tempf = os.tmpfile()

I'm trying to set the LaTeX \odot symbol in the gnuplot (4.6.0) pdf terminal. What is the exact syntax for this? The gnuplot FAQ gives some clues, but should I type {/Symbol \2299} , or {/utf8 \2299} , or some other variation on \ , / , # etc.? Or should I do set encoding utf8 ? Pasting the symbol in directly does not seem to work. Should I use pdf or pdfcairo for the terminal? The latter affects my plots in intolerable ways. Lee Phillips It is pretty simple. First you need to select a terminal that supports Unicode; then you can indeed paste your Unicode characters in directly. The old pdf
