Abstract: Cropping source images for display on user devices. A source image is cropped and/or resized to correspond to dimensions of a display screen of a device by selecting an area of interest of the source image which will not be lost in the process of resizing the image. Coordinate points are positioned within the image to correspond to dimensions of the display screen on which the image will be displayed and the image is then cropped at the boundaries defined by the coordinate points which include a crop height and a crop width. If needed, the image is then scaled down proportionally to resize the image to a size that corresponds to the dimensions of the display screen of the device.

Abstract: A door structure, said structure for use particularly, although not necessarily exclusively, to selectively close an opening between a first environment which is at a temperature which is lower than the temperature of the environment on the opposing side of the opening. The door is provided with a structure so as to define a cavity-therein into which air is caused to flow. The door has formations and a structure so as to encourage uniform air flow through the cavity and hence prevent or minimise the creation of condensation and/or frost on the door structure.
