Hello,

I want to copy an area from the canvas. There is an api in midp - javax.microedition.lcdui.Graphics



Copies the contents of a rectangular area (x_src, y_src, width, height) to a destination area, whose anchor point identified by anchor is located at (x_dest, y_dest). The effect must be that the destination area contains an exact copy of the contents of the source area immediately prior to the invocation of this method. This result must occur even if the source and destination areas overlap.

For example, I want to copy a rectangular area oldx,oldy,oldw and oldh to new positions newx, newy one will write,


Is there any equaivalent api for copyArea in android?

Thanks!

If you have access to the Bitmap 'behind' the canvas, you could use the following:

static Bitmap.createBitmap(Bitmap source, int x, int y, int width, int height)
Returns an immutable bitmap from the specified subset of the source bitmap.

Thanks for your reply. Yes i can access to the canvas bitmap.


Also can you please look at this thread,
invoking_widgets_ondraw_from_custom_views_ondraw-t3020.html

I have my own view and in myview's onDraw() method i want to paint android widgets for example a edittext, textview or a progressbar.

Can i do it by just calling those widget's draw method which will invoke widget's onDraw() to draw the widget?

If i use a layout and add a progressbar in it and setcontentview of the layout then the same process will happen right? The implementation will call widget.draw() and that invoke widgets ondraw() method to draw the widget.

Thanks!
