Converting problematic pdf's to png

[michelle]

Just a quick comment (in case this effects anyone else) - my .tif to pdf conversions started to go a bit "light". That is, a lot of the lines of the original file to convert because invisible in the convertedPNG.png file.

So, I tweaked the command by increasing the density from 72 to 300. Lucky guess though, I don't really understand why it works but for the 25 images I tested - raster pdfs / vector pdfs / .tifs - - it does.

Code: Select all

convert -density 300 convert.tif -scale @550000 -flatten PNG8:converted-hooray.png
