Thanks for your kind reply, I know the concept of press print screen button and edit in paint....etc. But it is again a extra work to edit the images. So am looking for a Optimize solution it will capture entire composite.xml pane.
ya I have already used this Snipping Tool. But it can capture the some part in JDeveloper and would mine tell me, what are the best software's are available for merging images like image1, image2 ... etc.
