It happens that scaling of an image of 5MB leads to an OutOfMemory Error in heap space, even if memory reports suggest that there are 80MB free memory. Maybe its a problem of coninuous memory? I don't know.

Bluring seems to be very memory intensive, and therefor you can set the "max blur size" to a lower level which prevent larger images from beeing blurred.

Subject: [opencms-dev] How can I write Pictures to static export
	folder?
Message-ID: <tencent_0D15716D6F488BB5731EB51F at qq.com>

Hi, all,

How could I export one single file to static export folder? 

I try to write a picutre to static export folder in my program, but once the file was created, it was deleted automatically by system. Note: the file is uploaded & published.


Could anybody tell me why?

Fantasy
