Constructor Details

ComponentColorModel

public ComponentColorModel(ColorSpace colorSpace,
                           boolean hasAlpha,
                           boolean isAlphaPremultiplied,
                           int transparency,
                           int transferType)
Construct a new ComponentColorModel. This constructor makes all bits of each sample significant, so for a transferType of DataBuffer.BYTE, the bits per sample is 8, etc. If both hasAlpha and isAlphaPremultiplied are true, color samples are assumed to be premultiplied by the alpha component. Transparency may be one of OPAQUE, BITMASK, or TRANSLUCENT.
Parameters:
colorSpace - The colorspace for this color model.
hasAlpha - True if there is an alpha component.
isAlphaPremultiplied - True if colors are already multiplied by alpha.
transparency - The type of alpha values.
transferType - Data type of pixel sample values.
Since:
1.4
