Hi there, thanks very much for these very useful examples.

I’m converting to png and displaying a postscript file (ps). The file has more than one page (not unlikely a pdf).

If I load the images without [] it will always show the last page; instead if I put in any index number, it will always show the first page only. For example:

$im->readImage( ‘test.ps[2]‘ ); //shows the first page instead of the third

Any ideas of why this is happening?

Cheers,
R

So how can I use a similar technique to get a preview of the 1st page of a pdf file that is on an other server?

Usually, doing things on files on an other server is well supported in the Internet. Examples of this are: hot linking to a jpg file, using the html5 video tag for a video on an other server, etc. So there must be a way for image previews for pdfs as well.

ppva,

the [] notation at end works only with local files.

A very basic question:

$im = new imagick( ‘test.pdf[0]‘ );

Could this work for a file on an other server, eg.

$im = new imagick( ‘http://www.otherserver.com/test.pdf[0]‘ );

or is imagick only designed to work for same-server files?

For those not happy with the default quality of the PNG preview of the PDF, this will make a big difference. Note that you must set the resolution before reading the image:

$im = new imagick();
$im->setResolution(600,600);
$im->readImage($filepath);
$im->setImageFormat(“png”);
$im->setImageDepth(8);
$im->setImageCompressionQuality(90);
$im->scaleImage(500,0);

The only problem is the filesize ends up being very large, but text is actually readable, unlike imagemagick’s defaults.
