src
- The image to convert to sRGB.public static CachableRed wrap(java.awt.image.RenderedImage ri)
If ri is already a CacheableRed it casts it down and returns it.
In cases where ri is not already a CacheableRed it wraps ri with a helper class. The wrapped CacheableRed "Pretends" that it has no sources since it has no way of inteligently handling the dependency/dirty region calls if it exposed the source.

- The y location for the upper left corner of the

This method should only be used if you need a WritableRaster due to an interface (such as to construct a BufferedImage), but have no intention of modifying the contents of the returned Raster. If you have any doubt about other users of the data in ras, use copyRaster (above).
ras
- The raster to make writable.public static java.awt.image.WritableRaster makeRasterWritable(java.awt.image.Raster ras, int minX, int minY)
You can specify a new location for the returned WritableRaster, this is especially useful for constructing BufferedImages which require the Raster to be at (0,0). This method should only be used if you need a WritableRaster due to an interface (such as to construct a BufferedImage), but have no intention of modifying the contents of the returned Raster. If you have any doubt about other users of the data in ras, use copyRaster (above).
