Re: Resizing images using imgscalr
Yes, I would second my own recommendation for using JAI. It works great for this. I store large TIFF images in Postgres as blobs and scale them on the fly based on the HTTP request params. I have fixed sizes, like thumbnail, and info, but also support support arbitrary sizes. Only specify x, or y and the scaling is proportional.

Re: Resize images
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.

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 - To unsubscribe, e-mail: users-unsubscr...@cocoon.apache.org For additional commands, e-mail: users-h...@cocoon.apache.org
Capture or Output data from current flow state to PDF
Hello,
Using Cocoon 2.2, I am trying to generate some PDF interactively using flow.
The flowscript loops, continually getting input from the user, allowing them to
add content via form submission. The input is collected and used to
dynamically build a document. This part works using the sitemap.xmap below.
What I would like to do next is take the current state of the data collected in
the flow and transform to PDF.
I'm not sure how to capture the output of the current flow state.
Can this be done at all?
If so, can it be done inside the pipeline without writing to a temporary file?
Using Cocoon 2.2 is not a requirement so if this is achievable with a different
version that is OK.
