Hello, I am looking for a little guidance on transcoding large images. I have a process that produces large images (using ILog JViews) that I'd like to ultimately have deliver to a web user. The first pass through was to produce a JPEG, but memory is constraint and loading up a bufferedimage triggers an OOM exception and now I am looking for an alternative. Here are some things I've considered:
1. Produce a large SVG and slice it so that it produces smaller PNGs/JPEGs. I am not sure if batik supports this or not. I do not know if it is as simple as adjusting the viewport and then rendering? 2. Produce a large SVG and transcode it to TIFF. I see there is a TiledImageTranscoder in the contrib, and I was able to get it to produce a TIFF, but image quality was terrible. Maybe there is a hint that I am missing? 3. Produce a large SVG and transcode it to another image format for slicing. Tried this and it looks like the transcoder for PNG and JPEG use a buffered image. Does anyone have any experience with such a problem? I have very little control over how much heap I can give my process as it runs in a shared environment along with two other web apps. I have plenty of storage though, so if there is a streaming style of transcoding where parts of an image source are read and then written in chunks, that would be ideal. But considering how JPEG and SVG work, I don't think that's even an option. Any help is appreciated. Thanks! Al
