Constructor Detail

ImageRawPNG

public ImageRawPNG(ImageInfo info,
                   InputStream in,
                   ColorModel colorModel,
                   int bitDepth,
                   ICC_Profile iccProfile)

Main constructor.

Parameters:

info - the image info object

in - the ImageInputStream with the raw content

colorModel - the color model

bitDepth - the bit depth

iccProfile - an ICC color profile or null if no profile is associated

Method Detail

getBitDepth

public int getBitDepth()

The bit depth of each color channel.

Returns:

the bit depth of one channel (same for all)

getICCProfile

public ICC_Profile getICCProfile()

Returns the ICC color profile if one is associated with the PNG image.

Specified by:

getICCProfile in interface Image

Overrides:

getICCProfile in class AbstractImage

Returns:

the ICC color profile or null if there's no profile

getColorModel

public ColorModel getColorModel()

Returns the image's color model.

Returns:

the color model

getColorSpace

public ColorSpace getColorSpace()

Returns the image's color space.

Specified by:

getColorSpace in interface Image

Overrides:

getColorSpace in class AbstractImage

Returns:

the color space

setGrayTransparentAlpha

protected void setGrayTransparentAlpha(int gray)

Sets the gray transparent pixel value.

Parameters:

gray - the transparent pixel gray value (0...255)

setRGBTransparentAlpha

protected void setRGBTransparentAlpha(int red,
                                      int green,
                                      int blue)

Sets the RGB transparent pixel values.

Parameters:

red - the transparent pixel red value (0...255)

green - the transparent pixel green value (0...255)

blue - the transparent pixel blue value (0...255)

setTransparent

protected void setTransparent()

Used to flag image as transparent when the image is of pallete type.

isTransparent

public boolean isTransparent()

Whether the image is transparent (meaning there is a transparent pixel)

Returns:

true if transparent pixel exists

getTransparentColor

public Color getTransparentColor()

The color of the transparent pixel.

Returns:

the color of the transparent pixel.

setRenderingIntent

public void setRenderingIntent(int intent)

Used to set the rendering intent when the color space is sRGB.

Parameters:

intent - the rendering intent of the sRGB color space

getRenderingIntent

public int getRenderingIntent()

Returns the rendering intent of the sRGB color space.

Returns:

the rendering intent
