Text modification

A computer program product, stored on a tangible information carrier, the product comprising instructions operable to cause a computer system to perform a method comprising:

• defining a modifier to be applied to a text object having text units, wherein defining the modifier comprises:
• defining two or more selection functions for the modifier, each selection function identifying two or more of the text units and setting selection values that can vary among the two or more text units, the selection values being non-binary and representing a degree of modification to be applied;
• associating the two or more selection functions with the modifier;
• defining one or more property components for the modifier, each property component specifying a modification of a property associated with the two or more text units;
• associating the one or more property components with the modifier;
• in response to an instruction to apply the modifier to the text object, combining the two or more selection functions to calculate aggregate selection values and modifying the text object by applying the modification specified by each of the one or more property components associated with the modifier to the two or more text units on a per text unit basis and in accordance with the aggregate selection values;
• using the modifier to create a plurality of modified text objects;
• and
• defining an animation sequence based on the text object and the plurality of modified text objects.

A computer-implemented method, comprising:

• defining text animation with a plurality of modifiers to be applied to a text object having text units and a sequence of modifiers;
• defining one or more selection functions for each of the plurality of modifiers, each selection function identifying one or more of the text units and setting a non-binary selection value representing a relative amount of modification to be applied;
• defining one or more property operations for each selection function, each property operation specifying a modification of one or more properties associated with the one or more of the text units and having a baseline value representing a complete application of the modification;
• and
• animating the text object including applying the plurality of modifiers to the one or more selection functions on a per selection function basis in accordance with the selection value relative to the baseline value and the sequence of modifiers.

A system comprising:

• a machine-readable storage device including a computer program product;
• a display device;
• and
• one or more processors capable of interacting with the display device and the machine-readable storage device, and operable to execute the computer program product to perform operations comprising:
• defining a modifier to be applied to a text object having text units, wherein defining the modifier comprises:
• defining two or more selection functions for the modifier, each selection function identifying two or more of the text units and setting selection values that can vary among the two or more text units, the selection values being non binary and representing a degree of modification to be applied;
• associating the two or more selection functions with the modifier;
• defining one or more property components for the modifier, each property component specifying a modification of a property associated with the two or more text units;
• associating the one or more property components with the modifier;
• and
• in response to an instruction to apply the modifier to the text object, combining the two or more selection functions to calculate aggregate selection values and modifying the text object by applying the modification specified by each of the one or more property components associated with the modifier to the two or more text units on a per text unit basis and in accordance with the aggregate selection values;
• and
• using the modifier to create a plurality of modified text objects;
• and
• defining an animation sequence based on the text object and the plurality of modified text objects.
