Gaming API and Sound

24-bit color format (0xRRGGBB). The method parameters are the following: dest - The mutable destination Image whose pixels will be set; x - The horizontal location of left edge of the region; y - The vertical location of the top edge of the region; width

- The width of the region; height - The height of the region; and rgbData - The array of RGB pixel values.

•public static void setPixels(javax.microedition.lcdui.Image dest, int[] rgbData) throws ArrayIndexOutOfBoundsException, IllegalArgumentException – Sets RGB pixel data in the entirety of the destination image. The data must be stored in the int array in row-major order using the standard 24-bit color format (0xRRGGBB). The method parameters are dest - The mutable destination Image whose pixels will be set, and rgbData - The array of RGB pixel values.

•public static Image getScaleImage(javax.microedition.lcdui.Image src, int width,

int height, int method) throws IllegalArgumentException – Creates a scaled version of the source image using the desired scaling method. All platforms must implement the SCALE_REPLICATE scaling method; other scaling methods may be optionally supported. SCALE_REPLICATE is used if the requested scaling method is not supported by the device. The method parameters are the following: src - the source Image; width - the width, in pixels, of the new Image, height - the height, in pixels, of the new Image, and method - The desired method to be used to scale the image data (see the item 0).

Using ImageUtil

The following code sample uses an image (tank.png) to create a data structure

(rgbData) to stores the RGB pixel data. The rgbData is used to draw the same image.

The following is a code sample to show implementation of rgbData:

rgbData

try {

Image tank = Image.createImage("tank.png");

}catch(Exception e) {

//The image can't be loaded

//creates a data structure to stores the RGB pixel data from Image

int rgbData[] = new int[tank.getHeight()*tank.getWidth()];

//Stores the RGB pixel data from Image ImageUtil.getPixels(tank,rgbData);

//Draws the image pixel by pixel with the respective RGB pixel data

for (i=0;i<tank.getHeight();i++) { for (j=0;j<tank.getWidth();j++) {

g.setColor(rgbData[i*tank.getWidth() + j]); g.fillRect(j,i,1,1);
