setSourceProgressivePasses

[leemon]

Hi!

I'm using the following code to create thumbnails from images. The two ImageReadParam specified are parameters to improve the reading performance of the source images. I'd like to know how can I tweak these parameters quite a bit to get more performance, because I'm not an expert in 2D subjects.

1   2   3   4   5

... param.setSourceProgressivePasses(0, 4); param.setSourceSubsampling(128, 128, 0, 0); BufferedImage image = reader.read(0, param); ...

Thanks in advance
