Image scaling with ImageMagick

Intrexx automatically scales uploaded images in various places, such as in the file selection or file sorting. These two elements can be found in the "Applications" module.

Alternatively, Intrexx can also use ImageMagick for scaling. If you have installed ImageMagick on your system, we will show you here which installation methods are possible.

1. Environment variable

Set the system environment variable "MAGICK_HOME" to the Intrexx installation directory.

2. System property

A property can be written via the "portal.wcf" file, which you can find in the Intrexx portal directory "internal/cfg". The property "de.uplanet.imagemagick.convert" must be set to the executable to be used (magick.exe or convert.exe or bin/convert). Example

 -Dde.uplanet.imagemagick.convert=/mypath/convert

3. Installed in the default directory

If ImageMagick is installed in a default directory, Intrexx will automatically find it there.

mac OS

 /usr/local/bin/convert
/opt/local/bin/convert

Linux

 /usr/bin/convert

Windows

 %ProgramFiles%\ImageMagick*\

Check whether ImageMagick is being used by Intrexx

Intrexx enters an INFO in the portal log file when ImageMagick is used for the first time. If you want to check whether Intrexx is using ImageMagick, you must restart the portal service. Then scale any image, e.g. by uploading the image with a file selection and automatically creating a thumbnail. The corresponding INFO is then written in the portal.log. Here is an example of the entry in the portal.log: 
INFO 2021-07-27T07:46:38,295Z - de.uplanet.lucy.server.util.image.ImageUtil[http-nio-0.0.0.0-1337-exec-7]
		ImageMagick has been found.

Refresh / delete thumbnails

The "refreshfilemetadata.bat" file, which can be found in the "bin/windows" installation directory, can be used to delete existing thumbnails. As soon as the old thumbnail is called up again in the browser, the new thumbnail is created.

To do this, start the command prompt (cmd) with a right-click to run it as administrator. Then enter the path to the file "refreshfilemetadata.bat", followed by a space and then the path to the portal.

Example:

c

:\intrexx\bin\windows\refreshfilemetadata.bat c:\intrexx\org\portal
