Hi Heath

Thanks for the swift answer.

This is actually the same article i started with. This approach is fairly straight forward and after some tweaking I manged to get this to work.

The main disadvantage is that the mask and the image needs to be exactly the same size. Meaning that you need to work with fixed size images. This is ok for some of our project but many projects have a fixed image width but a flexible height. All dependent on the original image ratio.

So what I need is an approach where 4 corner images/masks are composed on the image creating the mask.

Any ideas?

One solution is to use PostParameters to round the corners of *ALL* images. This is because the PostParameters setting isn't escaped onto the command line, as are the Filters. I couldn't get the ImageMagick command line options used for rounding to pass properly through the escaping using Filters.

Formats that don't support transparency don't display the rounded corners, thus, .jpgs are unchanged, unless you choose to use one of the 'rounded' aliases.

ez/settings/override/image.ini.append.php

<?php /* #?ini charset="utf-8"?

[AliasSettings]
AliasList[]=rounded-small
AliasList[]=rounded-medium
AliasList[]=rounded-large

[rounded-small]
MIMEType=image/png
Reference=small

[rounded-medium]
MIMEType=image/png
Reference=medium

[rounded-large]
MIMEType=image/png
Reference=large

[ImageMagick]
IsEnabled=true
ExecutablePath=/usr/local/bin
Executable=convert
ExecutableUnix=convert

# This line causes ALL images to have their corners rounded. Only .gifs and .pngs will display with rounded corners, .jpgs
# will display with sharp corners, because they don't support transparency. If a .jpg image is uploaded, the display class
# must be set to one of the above for the rounded corner version to display.
#
# The PostParameters settings must also be applied before the destination file name, modify /var/www/html/ez/lib/ezimage/classes/ezimageshellhandler.php
#
# Thanks to: http://www.imagemagick.org/Usage/thumbnails/#rounded
PostParameters=\( +clone -threshold -1 -draw "fill black polygon 0,0 0,10 10,0 fill white circle 10,10 10,0" \( +clone -flip \) -compose Multiply -composite \( +clone -flop \) -compose Multiply -composite \) +matte -compose CopyOpacity -composite

I modified /var/www/html/ez/lib/ezimage/classes/ezimageshellhandler.php to place the Filters and PostParameters between the source and destination filenames, because this is how I usually work with ImageMagick.

/var/www/html/ez/lib/ezimage/classes/ezimageshellhandler.php

if ( $filters !== false )
{
foreach ( $filters as $filterData )
{
$argumentList[] = $this->textForFilter( $filterData );
}
}

/* Move PostParameters up before the destination file is named */
if ( $this->PostParameters )
$argumentList[] = $this->PostParameters;

$destinationURL = $destinationMimeData['url'];

Finally, although I tried to use the debug settings to output the commandline, I didn't have any luck. To support development, I added the following line to the same file:

file_put_contents('/tmp/eZ.out',$systemString."\n",FILE_APPEND);

/* Added just before the execution */
system( $systemString, $returnCode );[/
