Re: Resizing images using imgscalr

2014-09-25 Thread Peter Sparkes 

Hi

The importClass(Packages.problem has been fixed.

I now get the following error

org.mozilla.javascript.EvaluatorException: 
file:///usr/share/tomcat7/instances/chinese-dev/webapps/ROOT/office/flow/upload_example.js, line 
103: Can't find method org.imgscalr.Scalr.resize(java.awt.image.BufferedImage,java.lang.Integer).


The problem I have is that I am not a java programmer

Regards

Petere

importClass(Packages.java.io.File);
importClass(Packages.java.io.FileOutputStream);
importClass(Packages.java.io.FileNotFoundException);

importClass(org.imgscalr.Scalr);


This does not have the importClass(Packages. prefix that explains why later this class is not 
defiened. However I personally would solve that with java.

Yes, I would second my own recommendation for using JAI.  It works great for 
this.  I store large TIFF images in Postgres as blobs and scale them on the fly 
based on the HTTP request params.  I have fixed sizes, like thumbnail, and 
info, but also support support arbitrary sizes.  Only specify x, or y and the 
scaling is proportional.
