Method Detail |
public static Image createImage(int[] pixels, int width, int height)
Image
object from a pixel array.
Internally, a Frame
object is used to call its
Component.createImage(int, int)
method
with a MemoryImageSource
object.
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 createdpublic static Image convertToAwtImage(PixelImage image, int alpha)
Image
from an instance of
RGB24Image
.
This will require image.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.
image
- the RGB24Image to be converted
public static Image convertToAwtImage(BilevelImage image, int alpha)
image
- the image to be convertedalpha
- the transparency value to be written to each
pixel in the resulting image
public static Image convertToAwtImage(Gray16Image image, int alpha)
image
- the grayscale image to be convertedalpha
- the alpha value, bits must only be set in the top eight bits
public static Image convertToAwtImage(Gray8Image image, int alpha)
image
- the grayscale image to be convertedalpha
- the alpha value, bits must only be set in the top eight bits
public static Image convertToAwtImage(Paletted8Image image, int alpha)
public static Image convertToAwtImage(RGB24Image image, int alpha)
public static Image convertToAwtImage(RGB48Image image, int alpha)
public static RGB24Image convertImageToRGB24Image(Image image)
RGB24Image
from the argument AWT image instance.
image
- AWT image object to be converted to a RGB24Image
RGB24Image
object holding the image data from the argument image
