Intelligent scrolling of electronic document

A device comprising:

• a display screen;
• a non-transitory machine readable medium storing a program for scrolling an electronic document that is displayed in a display area on the display screen, the program comprising sets of instructions for:
• receiving a definition of the electronic document comprising a plurality of different components;
• defining a set of snaplines within the electronic document based on a set of locations associated with a set of components of the electronic document;
• receiving a scroll input;
• identifying a first scroll stoppage location based on the received scroll input for terminating the scrolling;
• identifying a candidate region around the identified first scroll stoppage location, wherein the candidate region is identified based upon the identified first scroll stoppage location independent of whether any defined snaplines are identified within the candidate region, wherein each snapline defines a location for terminating scrolling of the electronic document across the display area instead of the identified first scroll stoppage location that is identified based on the received scroll input;
• wherein at least two different snaplines have different priorities for allowing selection of one of the two snaplines when both the snaplines are within the candidate region around the identified first scroll stoppage location based on received scroll input;
• selecting, from the two snaplines, a snapline within the region that has a highest priority value;
• and
• terminating the scrolling at the selected snapline so that, instead of the first scroll stoppage location, the respective location of the selected snapline is at a boundary of the display area.

A non-transitory machine readable medium storing a program for scrolling an electronic document that is displayed in a display area on a display screen, the program comprising sets of instructions for:

• defining a plurality of snaplines within the electronic document based on a set of locations associated with a plurality of corn orients of the eletronic document;
• receiving a swipe gesture on a touch-sensitive input surface, the swipe gesture having a velocity;
• scrolling the electronic document on the display screen based on the swipe gesture;
• identifying a first scroll stoppage location on the electronic document for terminating the scrolling based on the swipe gesture;
• identifying a region around the identified first scroll stoppage location based upon the swipe gesture and prior to identifying any defined snapilnes within the region, wherein a size of the region is based on the velocity of the swipe gesture;
• within the region, selecting a snapline that is defined at a second location of the electronic document, the snapline being a first snapline in the region in a direction of the scrolling;
• and
• terminating the scrolling at the second location so that, instead of the first scroll stoppage location, the second location of the identified snapline within the region is at a boundary of the display area.

A device comprising:

• a display screen;
• a non-transitory machine readable medium storing a program for scrolling an electronic document that is displayed in a display area on the display screen, the program comprising sets of instructions for:
• receiving a definition of the electronic document to display;
• dynamically generating a layout of the electronic document based on a set of characteristics of the electronic document;
• defining a plurality of snaplines within the dynamically generated layout, the snaplines for defining locations for terminating scrolling of the electronic document across the display area in place of a first scroll stoppage location that is identified based on a received scroll input;
• receiving the scroll input;
• and
• identifying:
• (i) the first scroll stoppage location on the electronic document for terminating the scrolling based on the received scroll input;
• (ii) a region around the identified first scroll stoppage location, wherein the region is identified based upon the first scroll stoppage location, and the region is identified independent of whether any of the plurality of defined snaplines are identified within the region;
• and
• (iii) the plurality of snaplines within the region, wherein each of the plurality of snaplines comprises an assigned priority value and an assigned location within the electronic document;
• selecting, from the plurality of identified snaplines within the region, a snapline within the region that has a highest priority value;
• and
• terminating the scrolling at the selected snapline so that, instead of the first scroll stoppage location, the respective assigned location of the selected snapline is at a boundary of the display area.
