PDF to PNG conversion with good quality.

[h2shin]

I've been searching around for a while and still can't find a way to use imagick to convert a pdf file to a png file with good original quality.

I'm in need of converting pdf documents containing text as well as images to png files, in such a way that image/text is sharp and clear. Is there a way to do this within imagick?

All my attempts so far have been less than fruitful.

Use supersampling technique. Increase the density, then resize by the inverse of the density increase.

convert -density 288 image.pdf -resize 25% output.png

normal density is 72. So 72*4=288. Thus resize is 1/4=25%

But what about with the imagick extension? I really don't know how to work my way around that extension...

Sorry you will need to find the equivalent operations in Imagick. I am not an expert on Imagick. But see http://php.net/manual/en/book.imagick.php and resizeImage() and setImageResolution()
