Re: Resize images
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
groupIdorg.apache.cocoon/groupId
artifactIdcocoon-imageop-impl/artifactId
version1.0.0-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 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:

I get Unable to transform src image for

Any ideas how to get scaling and resizing working

Re: Resize images
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) Peter On 16/09/2014 13:52, Miguel wrote: Hi Peter It seems that there isn't access to image or similar error to read it.
