I am having some trouble with ImageMagick.
I have installed GhostScript v9.00 and ImageMagick-6.6.7-1-Q16 on Windows 7 - 32Bit
When I run the following comma
According to the site admin at the ImageMagick forum:
ImageMagick uses the pngalpha device when it finds an Adobe Illustrator PDF. Many of these are a single page. Ideally, Ghostscript would support a device that allows multiple PDF pages with transparency but it doesn't...
Easy fix. Edit delegates.xml and change pngalpha to pnmraw.
This worked for me. I don't know if it introduces any other problems however.
See this post from their forums.
I found this solution which convert all pages in the pdf to a single jpg image:
montage input.pdf -mode Concatenate -tile 1x output.jpg
montage is included in ImageMagick.
Tested on ImageMagick 6.7.7-10 on Ubuntu 13.04.
By the way if you need to convert first and second pages then provide in array comma separated values
convert D:\test\sample.pdf[0,1] D:\test\pages\page.jpg
Resulting JPEG files will be named:
page-0.jpg
page-1.jpg
You can also do
convert D:\test\sample.pdf[10,15,20-22,50] D:\test\pages\page.jpg
Resulting JPEG files will be named:
page-10.jpg
page-15.jpg
page-20.jpg
page-21.jpg
page-22.jpg
page-50.jpg
May be it will help to someone.
You can specify which page to convert by putting a number in [] after the filename:
convert D:\test\sample.pdf[7] D:\test\pages\page-7.jpg
It should have, however, converted all pages to individual images with your command.
