createImage
public static Image createImage(int[] pixels, int width, int height)
Creates aImage
object from a pixel array. Internally, aFrame
object is used to call itsComponent.createImage(java.awt.image.ImageProducer)
method with aMemoryImageSource
object.- Parameters:
pixels
- the image pixel data in the typical RGBA 32-bit format, one int per pixelwidth
- the horizontal resolution in pixels of the image to be createdheight
- the vertical resolution in pixels of the image to be created
-
convertToAwtBufferedImage
public static BufferedImage convertToAwtBufferedImage(PixelImage image)
-
convertToAwtBufferedImage
public static BufferedImage convertToAwtBufferedImage(RGB24Image image)
Convert a JIURGB24Image
to aBufferedImage
with the given alpha value (useRGBA.DEFAULT_ALPHA
as default).- Parameters:
image
- JIU image to be converted- Returns:
- a new BufferedImage
- Since:
- 0.14.2
-
convertToAwtImage
public static Image convertToAwtImage(PixelImage image, int alpha)
Creates an instance ofImage
from an instance ofRGB24Image
. This will requireimage.getWidth() * image.getHeight() * 4
bytes of free memory. This method checks the type of the argument image via instanceof and the calls the right convertToAwtImage method of this class.- Parameters:
image
- the RGB24Image to be convertedalpha
- alpha value to be used with each pixel- Returns:
- newly-created AWT image instance
-
convertToAwtImage
public static Image convertToAwtImage(BilevelImage image, int alpha)
Convert a BilevelImage object to an AWT image object.- Parameters:
image
- the image to be convertedalpha
- the transparency value to be written to each pixel in the resulting image- Returns:
- newly-created AWT image
-
convertToAwtImage
public static Image convertToAwtImage(Gray16Image image, int alpha)
Creates an AWT Image object from a Gray16Image object and an alpha value. This is done by allocating a new int array with image.getWidth() times image.getHeight() elements, copying the data to those ints (using transparency information from the top eight bits of the alpha argument) and calling Toolkit.createImage with a MemoryImageSource of those int[] pixels.- Parameters:
image
- the grayscale image to be convertedalpha
- the alpha value, bits must only be set in the top eight bits- Returns:
- AWT image created from the argument input image
-
convertToAwtImage
public static Image convertToAwtImage(Gray8Image image, int alpha)
Creates an AWT Image object from a Gray8Image object and an alpha value. This is done by allocating a new int array with image.getWidth() times image.getHeight() elements, copying the data to those ints (using transparency information from the top eight bits of the alpha argument) and calling Toolkit.createImage with a MemoryImageSource of those int[] pixels.- Parameters:
image
- the grayscale image to be convertedalpha
- the alpha value, bits must only be set in the top eight bits- Returns:
- AWT image created from the argument input image

-
convertImageToRGB24Image
public static RGB24Image convertImageToRGB24Image(Image image)
Creates anRGB24Image
from the argument AWT image instance.- Parameters:
image
- AWT image object to be converted to aRGB24Image
- Returns:
- a
RGB24Image
object holding the image data from the argument image
