A screen capture application captures image data by receiving a signal defining a display area for which image data is to be captured, accessing metadata relating to components within the defined display area, and, for components within the display area, storing an image of the component and storing associated position data. The screen capture application may store positional relationships between the components within the defined display area, the positional relationships including ordering of the components relative to each other. The screen capture application may store the components as a plurality of layers within a layered image file. The screen capture application may store the component images in respective files and store the position data in a control file. The control file may include details of the respective component image files.
