ImageMagick PDF to JPGs sometimes results in black background

Question

I have the following:

ghostscript-fonts-5.50-24
ImageMagick-6.7.2-1
ghostscript-9.02-1

Which I use to create a series of JPGs for each page usi

Answer 1

Simple fix to this issue is to use an image format that supports transparency, such as png.

So:

convert -density 175 -colorspace sRGB test.pdf -resize 50% -quality 95 test.png

Problem solved :)
