I am trying to convert a free ebook from PNG to JPG, so I can read it on my Sony Bravia KDL-40R470.
This is how I converted the PNG file:
convert -density 117 -quality 80 progit.pdf progit.jpg
Unfortunately, my TV refuses to display the image. Changing density and quality makes no difference.
However, when I manually capture a screenshot in a PDF viewer, crop that screenshot in GIMP and export it to JPG with the same quality of 80, the resulting image displays just fine on my TV.
However, manually converting hundreds of pages is simply not an option for me :)
Can anybody spot potential problems in the first JPG file that would make a TV refuse to display it? Which Imagemagick options would be recommended to mitigate these problems?
