GIF Transparency not preserved #5

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Reducing a GIF in quality will discard the transparency of the image,
resulting in a black background.  This can be duplicated with or without
heights and widths specified, as well as with and without zoom-crop.

you see black borders on the two sides.

Well, that's because you're using 20x gausian blur filter. Try to use same 
number of times that same filter in Photoshop with athat image, and watch magic 
... same will happend. Timthumb scripts works great, and this is wrong bug. 

Check same url without filter, is that ok ?
