13. A device, comprising: a display device configured to display a digital sketch comprising one or more panels, and one or more sketches each at least in part included in a respective one of the one or more panels; one or more processors to implement a comic creation module that is configured to generate the digital sketch performing operations comprising to: generate the one or more panels according to panel input specifying a border for each of the one or more panels on a displayed page of the digital sketch; generate the one or more sketches according to drawing input specifying one or more strokes on the page, wherein at least a portion of at least one of the one or more strokes is drawn in at least one of the one or more panels; erase a portion of the border for at least one of the panels according to an erase input; determine for each of the one or more panels, based on a windowing algorithm, which of the one or more strokes or portions of the one or more strokes are to be displayed in the digital sketch and which of the one or more strokes or portions of the one or more strokes are hidden in the digital sketch, the windowing algorithm configured to recognize the erased portion of the border and determine that the one or more strokes or portions of the strokes that pass through the erased portion of the border are to be displayed and the one or more strokes or portions of the strokes that do not pass through the erased portion of the border are to be hidden from display, and for a panel, the windowing algorithm configured to: determine that at least one of the strokes crosses the border of the panel; split each stroke that crosses the border of the panel to generate at least two separate strokes from the respective stroke; mark each stroke that lies inside the border of the panel to be displayed; determine at least one remaining unmarked stroke that intersects a marked stroke; and mark each remaining unmarked stroke that intersects a marked stroke as to be displayed and additional remaining unmarked strokes are hidden from display.
13. A device, comprising: a display device configured to display a digital sketch comprising one or more panels, and one or more sketches each at least in part included in a respective one of the one or more panels; one or more processors to implement a comic creation module that is configured to generate the digital sketch performing operations comprising to: generate the one or more panels according to panel input specifying a border for each of the one or more panels on a displayed page of the digital sketch; generate the one or more sketches according to drawing input specifying one or more strokes on the page, wherein at least a portion of at least one of the one or more strokes is drawn in at least one of the one or more panels; erase a portion of the border for at least one of the panels according to an erase input; determine for each of the one or more panels, based on a windowing algorithm, which of the one or more strokes or portions of the one or more strokes are to be displayed in the digital sketch and which of the one or more strokes or portions of the one or more strokes are hidden in the digital sketch, the windowing algorithm configured to recognize the erased portion of the border and determine that the one or more strokes or portions of the strokes that pass through the erased portion of the border are to be displayed and the one or more strokes or portions of the strokes that do not pass through the erased portion of the border are to be hidden from display, and for a panel, the windowing algorithm configured to: determine that at least one of the strokes crosses the border of the panel; split each stroke that crosses the border of the panel to generate at least two separate strokes from the respective stroke; mark each stroke that lies inside the border of the panel to be displayed; determine at least one remaining unmarked stroke that intersects a marked stroke; and mark each remaining unmarked stroke that intersects a marked stroke as to be displayed and additional remaining unmarked strokes are hidden from display. 17. The device as recited in claim 13 , wherein the comic creation module is configured to: receive an additional erase input erasing a portion of the border of an additional panel; and reapply the windowing algorithm to the additional panel in response to said erasing the portion of the border of the additional panel.
