Mac OS X: decoder jpeg not available
If you are using PIL(Python Imaging Library) on Mac OS X(Tiger), you will probably have a “decoder jpeg not available” when resizing a jpeg image.
This probably means that PIL doesn’t have JPEG support, because libjpeg wasn’t found when PIL was being configured.
Here is the solution:
This probably means that PIL doesn’t have JPEG support, because libjpeg wasn’t found when PIL was being configured.
Here is the solution:
- Download, compile and install jpeglib and zlib
-
Edit PIL setup.py and change to:
JPEG_ROOT = "/usr/local/include" ZLIB_ROOT = "/usr/local/include"
-
Compile:
python setup.py build_ext -i
-
Test:
python selftest.py
-
If the result is something like this:
"57 tests passed."
-
You are ready to go:
python setup.py install
