Mogrify from multi-pdf to png to multi-tiff

[benito2313]

Hello,

I'm trying to get a multi-pdf to a png and then to a multi-tiff.
But because png cant handle multi pages it puts out "_0" and "_1" after the file name.
My question is how can i put these png files back in a multi tiff (I have multiple pdf with single pages and multiple pages)

i know i can do this directley if i take out the png, but for some reason tesseract doesnt support the file if i do this.

my code now is:
mogrify -denisty 300 -format png +matte *.pdf
mogrify -denisty 300 -format tiff -colorspace Transparent -auto-level -auto-orient +matte *.png

Regards,

Does this not work?

mogrify -density 300 -format tiff +matte *.pdf

This works fine for me in IM 6.8.4.10 Mac OSX Snow Leopard as a simple test


convert rose: rose: rose: rose.pdf
mogrify -format tiff rose.pdf

You misread my post. I started with a multipage pdf and converted using mogrify to a multipage tiff.

The multipage pdf was created from combining 3 rose: images into one multipage pdf, since I did not have any other multipage pdfs around. There is no png involved.

By mult-tiff, do you mean multi-page tiff or a pyramid-tiff?

You also never mention your IM version or platform. Please see viewtopic.php?f=1&t=9620

If I wanted to convert a multi-page PDF to a multi-page TIFF via individual PNG files, this is how I would do it:

Code: Select all

convert x.pdf x-%06d.png
convert x-*.png x.tiff

To convert many PDF files, I would put this an a script loop. Perhaps mogrify could do it without a script loop.

However, I'm curious about the tesseract problem. Can you supply a multi-page TIFF that tesseract can use, and one that it can't?

There should be no reason to convert to intermediate png, just to then convert to tiff. Mogrify should handle the multipage pdf to multipage tiff just fine as I demonstrated.

My problem is solved by using mogrify to .mng file.
Thanx for your help and input
