Hello Dr. Hoffmann,


many thanks for your posting here.

This is afair similiar to that way we use for fully automatic resampling / 
resizing of ZMS images - images are "just" resampled / resized to a given 
resolution / dimensions or thumbnailed.

Bit our problem is, that many screenlayouts use fixed width thumbnails (i.e. 
100x100 pixel or "1/1") while users typically have (and want to upload) image 
files width very different dimensions (i.e. 500x200, 640x480, 480x620 etc...).

The only practicable solution from our view is to let the user (human) select 
a suitable (correctly dimensioned) part of that image.

As you might know (or used for the ZMS functionality) the former 
"zmsgraphic_extedit" from CMESS (used in the Gallery object):

	http://zmslabs.org/trac/browser/CMESS/zmsgraphic_extedit?rev=986

it allowed to:

	- pre-set cropping and resize dimensions. 
	- extending the editor with further functionality

I thought these code (or principe) was "going into" ZMS (core) now as it seems 
very similiar in parts and it would make really sense to have such a way of a 
flexible interface to ZMS applications, allowing ZMS admins / devels to adopt 
it within their own objects and / or extend the image editor as required (like 
the ZMSText editor is "extensible" now).

Unfortunately these code just works as an "action" with "ZMSGpraphic" objects 
and may overlay with the future image edit functionality of core ZMS:

Are there any plannings to implement this or should i prefer CMESSs 
zmsgraphic_extedit for this?

Many thanks to all - ZMS 2.13 is very nice work!...


best regards,


Niels.
