问题
I want to merge two images in blackberry. one image is a big image and other image is a small one. position of small image will be define by developer. what are the possible ways?
回答1:
You can use the Graphics class to draw multiple Bitmaps onto it in different offsets. Look into the Graphic.drawBitmap function. We use something like:
graphics.drawBitmap(x1, y1, icon.getWidth(), icon.getHeight(), icon, 0, 0);
Where the graphics object is the one passed by the paint method we override and icon is the large image. Than determine the x y position for the smaller image and use the same method on the graphics object:
graphics.drawBitmap(x2, y2, mark.getWidth(), mark.getHeight(), mark, 0, 0);
Where mark is the smaller image.
Hope this helps :)
