Hi David,
Thanks for investigating it.
I am using java 6 on a linux box.
Unfortunately my java is not up to debugging it.
Would it work if I replaced the 2.1 jar with the 2.2 one
Regards

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.
Is there a difference between your versions of Java?
Please, has anyone got imageop scale and resize working on 2.1.12?
No. I looked yesterday at Cocoon running locally using the SVN branch
2.1.13-dev
The block samples show the same as what you described above.
The cocoon log file does show the errors, but doesn't mean much to me.
This was with Java 8.
The only thing that i can suggest is to look at the changes that
have been made to the code in 2.2 and compare with 2.1 branch.
http://svn.apache.org/viewvc/cocoon/branches/BRANCH_2_1_X/src/blocks/imageop/
http://svn.apache.org/viewvc/cocoon/trunk/blocks/cocoon-imageop/
Perhaps when the last changes were made, then there was a slight
difference, and perhaps no-one tested after that.
Those last changes seem to be
https://issues.apache.org/jira/browse/COCOON-2169
https://issues.apache.org/jira/browse/COCOON-2177

Thanks

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

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.

If you can use ImageMagick, you can try with:

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
