Can anyone suggest a good, Java-based raster library? By good, I mean a library that can read common raster formats (ex. tif, img...etc) and save them to other image formats (ex. png).

I say Java-based because I am investigating a simple GIS app for Android. I am aware that GDAL would seem like the obvious choice, but it seems like it will difficult to deploy GDAL with an Android application. If anyone knows otherwise, please enlighten me.

GeoTools is the Java equivalent of GDAL.

GeoTools seems to fit the bill, specifically the ImageIO-EXT. Hopefully the GeoTools library itself can handle the formats I am interested in, without needing the GDAL plug-in, only time will tell. –  user890 Nov 17 '10 at 15:02
