Subject: Resize images

Hi,

I currently have a cocoon application which enables the site
owner to upload images and then within the upload javascript
uses java to move the images to the required directory.

Most of the uploaded images are  large and therefore they are 
slow in displaying in a web page.


I, therefore, wish to resize them before saving them.

I am not sure how to do it.

Please, can anyone help

Thanks

Peter

Hi Miguel,

My java is not good enough debug the block imageop to see what parameters's 
value arrive to class

However as

 * Display image with original size and colour

Have you checked dependencies?
Have you tried to use block: cocoon-imageop-sample?
Can you show error message when you use transformer?

Hi Miguel,

I have implemented imageop, however, the only samples that work are:

  * Display image with original size and colour
  * Tint image various colour

I get Unable to transform src image for

  * Image scaling
  * Image resize

Any ideas how to get scaling and resizing working

Best wishes

Peter

Hi,

Thank you all for your replies.

As I believe it will be the easiest to implement, I am going to try imgscalr.

However, As I am using cocoon 2.1, Is there a way of using 
http://cocoon.zones.apache.org/cocoon22/cocoon-imageop-sample/ in cocoon 2.1


Best wishes

I use JAI to dynamically resize images for my site.  There are lot of examples if you 
google 'JAI image resize'.  I store higher res images and downscale them on the fly to the 
right size for the context they will be used in.  I wrote a plain old servlet to do it, but 
I'm sure it could be done in cocoon too.

Hi Peter,

If you can use ImageMagick, you can try with: http://im4java.sourceforge.net/

There are numerous image resizer programs out there.

Subject: Resize images

Hi,

I currently have a cocoon application which enables the site owner to 
upload images
and then  within the upload javascript uses java to move the images to the 
required
directory.

Most of the uploaded images are  large and therefore they are  slow in 
displaying in a
web page.

I, therefore, wish to resize them before saving them.

I am not sure how to do it.

Please, can anyone help

Thanks
