load
public Bitmap load(java.lang.String filename, boolean isLinear) throws java.io.IOException, BitmapReader.BitmapFormatException
Description copied from interface:BitmapReader

may be thrown. It is an error for this method to returnnull
.- Specified by:
load
in interfaceBitmapReader
- Parameters:
filename
- image filename to loadisLinear
- if this istrue
, the bitmap is assumed to be already in linear space. This can be usefull when reading greyscale images for bump mapping for example. HDR formats can ignore this flag since they usually always store data in linear form.- Returns:
- a new
Bitmap
object - Throws:
java.io.IOException
BitmapReader.BitmapFormatException
