DirectColorModel is used to construct the image from raw data. The
DirectColorModel model is similar to an X11 TrueColor visual, which has
the following parameters:
Number of bits: 32 Red mask: 0x00ff0000 Green mask: 0x0000ff00 Blue mask: 0x000000ff Alpha mask: 0xff000000 Color space: sRGB isAlphaPremultiplied: False Transparency: Transparency.TRANSLUCENT transferType: DataBuffer.TYPE_INT
The data may be arranged in one of two ways: by pixel or by plane. In both cases, the dataset will have a dataspace with three dimensions, height, width, and components.
For HDF4, the interlace modes specify orders for the dimensions as:
INTERLACE_PIXEL = [width][height][pixel components] INTERLACE_PLANE = [pixel components][width][height]
For HDF5, the interlace modes specify orders for the dimensions as:
INTERLACE_PIXEL = [height][width][pixel components] INTERLACE_PLANE = [pixel components][height][width]
