rgb parameter should have 3 entries.
The 'bKGD' chunk will encode this information.
public int[] getBackgroundRGB()
If the background color has not previously been set, or has been
unset, an IllegalStateException will be thrown.
IllegalStateException - if the background color is not set.public void setTransparentRGB(int[] transparentRGB)
Setting this attribute will cause the alpha channel of the input image to be ignored.
The 'tRNS' chunk will encode this information.
public int[] getTransparentRGB()
If the transparent color has not previously been set,
or has been unset, an IllegalStateException
will be thrown.
IllegalStateException - if the transparent color is not set.
