Hi
Cocoon 2.1.12
I can't get scale and resize function in the imageop block to work on cocoon
2.1.12.
I have the following working
* Display image with original size and colour
* Tint image various colour
Miguel has been kindly helping me, but he uses cocoon 2.2. Miguel has it
working on 2.2, see below.
Please, has anyone got imageop scale and resize working on 2.1.12?
Thanks
Peter

I've done some test and modulo in cocoon 2.2 project works fine. I describe
step by step:
a) Include dependency into pom file of my project:
<dependency>
<groupId>org.apache.cocoon</groupId>
<artifactId>cocoon-imageop-impl</artifactId>
<version>1.0.0-SNAPSHOT</version>
</dependency>
b) Include test map:match into sitemap.xmap:
<map:match pattern="prueba/*/scale-*-*">
<map:read type="image-op-scale" src="themer/themes/common/images/{1}">
<map:parameter name="scale-scale" value="{2}" />
<map:parameter name="output-format" value="{3}" />
</map:read>
</map:match>
<map:match pattern="prueba/*/resize-*-*">
<map:read type="image-op-resize" src="themer/themes/common/images/{1}">
<map:parameter name="size-width" value="{2}" />
<map:parameter name="size-height" value="{3}" />
</map:read>
</map:match>
"themer/themes/common/images/" is the route to my images's folder
c) start my project and I test:
* http://localhost:8080/prueba/audio.gif/scale-2.5-jpg
* http://localhost:8080/prueba/audio.gif/resize-100-50
All works fine.

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
* Tint image various colour
are working I assume there is access to image.
http://cocoon.zones.apache.org/cocoon22/cocoon-imageop-sample/ also gives
errors on resize (scalling)

Hi Peter
It seems that there isn't access to image or similar error to read it.
I advise you debug the block imageop to see what parameters's value arrive to
class.
This block has only three bugs, and all are fixed, so I think module must works.

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

Hi Peter
block imageop-samples exist for cocoon 2.1, and you can download in:

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

Hi Peter r
You can find examples to manage images in Cocoon:

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/

Peter,
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
Peter
