jpg to pdf - with original size

[KingCanadian]

Hello folks,

im trying to convert a jpg (scanned with 150 dpi) to a pdf with a4 papersize.
But the scan shoud appear in original size.

At first i tryed the following:

Code: Select all

convert test.jpg -page a4 out.pdf

But the image spans the complete width of the pdf.

Then i read the forum and googled:
the -density should help

So i tryed:

Code: Select all

convert test.jpg -page a4 -density 150 out.pdf

But nothing changes - the image is still not original size.
What am i doing wrong?

Regards
Juergen

I get the same results here. Also tried a two step conversion, but '-page a4' always blows up the graphic to canvas size.
You should give 'sam2p' a try, which is mentioned here [search for 'Image to PDF converters...']

I guess 'sam2p_pdf_scale.pl' simply changes the size of the pdf boxes (no size increase, as with the bigger A4 canvas).

Untested (running out of time).

Thank you for your reply,
but unfortunately sam2p too makes a pdf not with the original size and not in A4.

So i am still searching for a solution how can i get a jpg in original size to a A4pdf.

try resizing (-resize) to the size specified by the A4 page size (595x842). see http://www.imagemagick.org/script/comma ... s.php#page

Perhaps i should explain again:

My scanned jpg is in original 15x10cm - i want that to be shown and printed in the middle or top of a A4 PDF. The rest of the page should be white.

This works, but there are better ways to create such a PDF (e.g. ConTeXt).

Code: Select all

convert -density 150 -size 1239x1754 xc:white -density 150 test.jpg -gravity center -composite test.pdf

size: (210mm/25,4mm*150) x (297mm/25,4mm*150)

Try this command.
ImageMagick doesn't work well alone, but in tandem with other apps it will do the trick.
Check the output and functionality of the command @ http://convertjpgpdf.net

Code: Select all

convert -scale ".$HEIGHT."x".$WIDTH." -border ".$MARGIN."x".$MARGIN." -bordercolor white $inputfile $outputfile

find . -maxdepth 1 -iname 'page*.jpg' -exec sam2p '{}' '{}'.pdf \;"
sam2p_pdf_scale ".$PAGE_WIDTH." ".$PAGE_HEIGHT." page".$key.".jpg.pdf
pdfjoin page*.pdf --outfile out.pdf
