Field Detail

backgroundSet

private boolean backgroundSet

---

backgroundRGB

private int[] backgroundRGB

---

transparency

private int[] transparency

Constructor Detail

PNGEncodeParam.RGB

public PNGEncodeParam.RGB()

Constructs an instance of PNGEncodeParam.RGB.

Method Detail

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:

setBitDepth in class PNGEncodeParam

---

setBackgroundRGB

public void setBackgroundRGB(int[] rgb)

Sets the RGB value of the suggested background color. The rgb parameter should have 3 entries.

The 'bKGD' chunk will encode this information.

---

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.

---

isBackgroundSet

public boolean isBackgroundSet()

Returns true if a 'bKGD' chunk will be output.

Overrides:

isBackgroundSet in class PNGEncodeParam

---

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 IllegalStateException will be thrown.

---

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 IllegalStateException will be thrown.

---

unsetBackground

public void unsetBackground()

Suppresses the 'bKGD' chunk from being output.

Overrides:

unsetBackground in class PNGEncodeParam

---
