Unable to run

[monicaphalswal]

After doing this:

python gradify.py --demo --spread --single

I get this with a blank browser window: [19551:19551:0614/122502:ERROR:browser_main_loop.cc(201)] GTK theme error: Unable to locate theme engine in module_path: "adwaita", [19551:19551:0614/122502:ERROR:browser_main_loop.cc(201)] GTK theme error: Unable to locate theme engine in module_path: "adwaita", /usr/share/themes/Orchis/gtk-2.0/Apps/xfce.rc:150: error: invalid string constant "combo", expected valid string constant Created new window in existing browser session.

OS/Browser?

[monicaphalswal]

Ubuntu 14.04 LTS/Chrome

[fraser-hemp]

Interesting. Is the "demo.html" file in the directory that gradify.py is in, and if so, can you open it manually?

[monicaphalswal]

Yes they are in same directory and I am able to open them.

Hi Fraser Hemphill. Your demo is brillant. But unfortunately the script doesn't work on my machine (os x 10.10.3, python 2.7.6, pillow freshly installed). The demo.html is generated, but it is absolutely ermpty. On the other hand, the script doesn't report any error. Any idea? Thank you and best regards B.

Hi B, what does the program output when the --demo flag is not added?

[christianlerke]

Same issue as @borrisandreas on OS X as well as on Ubuntu Server. Running the command generates an empty demo.html even though the directory contains several images. No errors or warnings.

[fraser-hemp]

and with no --demo flag?

I think i found the issue. If i run it against a certain file using -f in the command I get this error:

Traceback (most recent call last):
  File "gradify.py", line 315, in <module>
    foo = Gradify()

    raise IOError("decoder %s not available" % decoder_name)

And here the error when attempting a png:

Oh yeah, I should have picked up on that. Currently only takes jpg type files, I'll add that to the readme

[christianlerke]

My bad -f for .jpg works on OS X but on Ubuntu it throws this error.

Traceback (most recent call last):
  File "gradify.py", line 315, in <module>
    foo = Gradify()
  File "gradify.py", line 57, in __init__
    self.get_file(self.args.file)
  File "gradify.py", line 197, in get_file
    self.get_directions(filen)
  File "gradify.py", line 85, in get_directions
    foo = foo.resize((100, 100), Image.ANTIALIAS)
  File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 1547, in resize
    self.load()
  File "/usr/local/lib/python2.7/dist-packages/PIL/ImageFile.py", line 203, in load
    d = Image._getdecoder(self.mode, d, a, self.decoderconfig)
  File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 419, in _getdecoder
    raise IOError("decoder %s not available" % decoder_name)
IOError: decoder jpeg not available

Probably just a missing library though.

Quick google suggests Ubuntu might need the jpeg encoder? http://askubuntu.com/questions/211627/how-to-add-support-for-the-jpeg-image-format

[christianlerke]

Thanks, its a great tool.

Hi Fraser

without —demo nothing happens. The script runs without error but also without any result.

Best regards B.

Hi, I had the same issue with the empty demo.html or if no demo option is given, I got no output. I could get it working with adding the option -d . while the "." represents the current directory. python ~/git/gradify/gradify.py --demo --spread -d .

Great tool!
