[Magick-bugs] Problems joining several images into a single pdf

Hello,

I ran into problems while converting images to pdf using convert:

a) Acrobat Reader does not draw the MediaBox around the image if the
image does not fill the entire page. This looks ugly if images of
different size or aspect ratio are merged into a single pdf.

convert in.png -page A4 out.pdf

Pdfs generated by gimp/cairo and merged by gs are displayed correctly.

b) The page switch has no visual effekt if several images are merged
into one pdf regardless wether -adjoin was explicitly specified or not.

convert in-1.png in-2.png -page A4 out.pdf

c) The CropBox values are to small. I get tiny pictures when merging
several pdfs into one by using the density switch.

convert in-1.png -page A4 -density 300 -units PixelsPerInch 1.pdf
convert in-2.png -page A4 -density 300 -units PixelsPerInch 2.pdf
convert 1.pdf 2.pdf -page A4 out.pdf

d) The output density of images gernerated by the gimp is
incorrectly multiplied by 2.5. This is probably a centimeter-inch /
locale issue.

convert in.png -density 300 -units PixelsPerInch out.png

Does anyone know a workaround?

Thanks

Karl
