Method Details
-
unsetBackground
public void unsetBackground()Suppresses the 'bKGD' chunk from being output.- Overrides:
unsetBackgroundin classmxPngEncodeParam
-
isBackgroundSet
public boolean isBackgroundSet()Returns true if a 'bKGD' chunk will be output.- Overrides:
isBackgroundSetin classmxPngEncodeParam
-
setBitDepth
public void setBitDepth(int bitDepth) Sets the desired bit depth for an RGB image. The bit depth must be 8 or 16.- Specified by:
setBitDepthin classmxPngEncodeParam
-
setBackgroundRGB
public void setBackgroundRGB(int[] rgb) Sets the RGB value of the suggested background color. Thergbparameter should have 3 entries.The 'bKGD' chunk will encode this information.
-
getBackgroundRGB
public int[] getBackgroundRGB()Returns the RGB value of the suggested background color.If the background color has not previously been set, or has been unset, an
IllegalStateExceptionwill be thrown.- Throws:
IllegalStateException- if the background color is not set.
-
setTransparentRGB
public void setTransparentRGB(int[] transparentRGB) Sets the RGB value to be used to denote transparency.Setting this attribute will cause the alpha channel of the input image to be ignored.
The 'tRNS' chunk will encode this information.
-
getTransparentRGB
public int[] getTransparentRGB()Returns the RGB value to be used to denote transparency.If the transparent color has not previously been set, or has been unset, an
IllegalStateExceptionwill be thrown.- Throws:
IllegalStateException- if the transparent color is not set.
