Call Transformer

[enkidu]

hi mates,

assuming i have a *-content.xml transformer calling imagemagick which scales jpeg files. how can i call my own written transformer explicitly from my java code?

[zladuric]

It should be the same as any other transformer. Once defined, you should be able to use that transformer from other code.

What is in your -context.xml transformer?
