An image is an instance of an Image object that has been previously created either by your MIDlet using a graphic context (discussed earlier in this chapter), or by graphics software Recall from the previous chapter, there are two kinds of images: a mutable image can be modified by your MIDlet, and an immutable image cannot be modified by your MIDlet You create an instance of an Image by calling the createImage() method The createImage() method requires one parameter or two parameters depending on whether you are drawing a mutable or immutable image One parameter is required for the createImage() method if the instance is used to draw an immutable image The parameter is the file name of the image, including the full directory path The following code segment illustrates this technique:

Two parameters are required for the createImage() method if the instance is used to draw a mutable image These parameters define the height and width in pixels of the memory block used to store the mutable image as it is being drawn The following code segment creates a block of memory 20 pixels high and 10 pixels wide for a total image size of 200 pixels

Some developers sketch a mutable image on graph paper to get a rough layout of the image and an estimate of the memory block size required to draw the image You ll use the instance as a parameter to the drawImage() method, which draws the image on the canvas You ll see how this is done later in this section The instance of the image is also used to create a mutable image You create a mutable image by calling the getGraphics() method of the Image class to return an instance of the Graphics class, which is the graphic context used to draw the mutable image Methods discussed in the Graphics section earlier in this chapter are used to draw elements of the mutable image Let s say that you want to create a mutable image of a line The following code segment shows you how this is done First, you must create an instance of the Image class by calling the createImage() method Next, you ll need an instance of the Graphics class that is created by calling the getGraphics() method And then you call the drawLine() method, as described previously in this chapter

Of course, your mutable graphic would be more complex than a simple line because you ll probably use other methods of the Graphics class to build an attractive image Each of these methods, however, must be called from the same instance of the Graphics class that is derived from the instance of the image you created in your MIDlet The drawImage() method is used to draw a mutable or immutable image on the canvas The drawImage() requires four parameters The first parameter is the instance of the Image class that references the image The next two parameters are integers that represent the coordinate used to position the image on the canvas The image is drawn within a virtual boundary box similar to the boundary box used to draw text on the canvas (see Text ) The coordinate represents the upper-left corner of the boundary box The last parameter is an integer that represents the portion of the image bounding box that is anchored at the specified coordinate The image anchor point is used to finely adjust the location of the image within the boundary box Table 7-5 lists constants used to represent image anchor points Two anchor points must be specified in the drawImage() method one for the horizontal position and the other for the vertical position This is nearly identical to the way anchor points are specified in the text drawing methods Here is a code segment that shows how to draw an image on the canvas This method is used to draw both mutable and immutable images The code segment centers the image
