Aspects of the subject technology relate to systems and methods for constraints-based layout and control of user interface (UI) elements. The system receives a first user input indicating an instruction to position a first UI element on a page of the layout application. The system receives a second user input indicating an instruction to position a second UI element on the page. The system receives a third user input indicating an instruction to create a connection from the second UI element to the first UI element. The system generates a layout constraint indicating a spatial relationship between the first UI element and the second UI element based on the connection. The system provides the layout constraint in a layout data file associated with the UI.

Constraints-based layout system for efficient layout and control of user interface elements

The subject matter of this specification can be embodied in, among other things, a method that includes receiving at a computing device that is in a locked state, one or more user inputs to unlock the device and to execute at least one command that is different from a command for unlocking the device. The method further includes executing in response to the user inputs to unlock the device an unlocking operation by the device to convert the device from a locked state to an unlocked state. The method further includes executing the at least one command in response to receiving the user inputs to execute the at least one command. The at least one command executes so that results of executing the at least one command are first displayed on the device to a user automatically after the device changes from the locked state to the unlocked state.

Input to locked computing device

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating a dynamic mesh for rendering with a graphical user interface. Graphical objects are rendered onto a layer having transparent pixels. The system infers what areas of the layer are drawn areas, and a mesh is generated based on the drawn areas.

Dynamic mesh generation to minimize fillrate utilization

An example method includes outputting, by a computing device and for display in a graphical development environment used during development of a software application, a graphical user interface associated with the software application, receiving, by the computing device, a development specification that associates a region of the graphical user interface with one or more candidate graphical objects for insertion into the graphical user interface, and receiving, by the computing device, an indication of a selection of the region of the graphical user interface. The example method further includes determining, by the computing device, based at least in part on the development specification and the indication of the selection of the region of the graphical user interface, a graphical object from the one or more candidate graphical objects, and outputting, by the computing device and for display at the region of the graphical user interface, an indication of the graphical object.

Predictive insertion of graphical objects in a development environment

Disclosed are apparatus and methods for rendering using a graphics processing component (GPC). A computing device can receive instructions for a GPC, including an instruction IA associated with a first portion of a canvas. An insertion position in an instruction buffer for instruction IA can be determined by: determining an instruction IB in the instruction buffer that is associated with a second portion of the canvas. If the first and second portions overlap, the insertion position can be based on an overlapping-instruction position of IB in the instruction buffer. Otherwise, if instructions IA and IB are similar, then the insertion position can be based on a second position of IB in the instruction buffer. Otherwise, the insertion position can be determined based on an ending position of the instruction buffer. Instruction IA can be inserted in the instruction buffer at the insertion position.

Overlap aware reordering of rendering operations for efficiency

Disclosed are apparatus and methods for tessellating shapes. A computing device that has a display can receive an instruction to draw a shape. The computing device can determine a scale factor for the shape. The computing device can determine a set of polygons that tessellate the shape based on the scale factor. The set of polygons can include at least two polygons. The computing device can display the polygons in the determined set on the display.

On-demand transformation aware shape tessellation

A method for storing information may include determining whether a received data object fits inside a particular one of a plurality of free blocks in a memory bitmap. Each of the plurality of free blocks may include a column of the memory bitmap with a top margin, a bottom margin, and a predetermined width. If the received data object fits, the received data object may be stored in the particular one of the plurality of free blocks, starting at the margin of the particular one of the plurality of free blocks. The particular one of the plurality of data blocks may be resized by moving the margin to start below or next to the stored received data object. The determining may include, for each of the plurality of free blocks, a height of the received data object may be compared with a height of each of the free data blocks.

Fast, dynamic cache packing

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for optimizing a display list. Graphics processing commands are identified for generation of one or more graphical images on a computer device. During an initial recording of a graphics display list to include the graphics processing commands, if a sub-list of the display list is determined to not include any drawing commands, the display list is recorded so that commands on the sub-list are not executed when the display list is executed.

Record-time optimization of display lists

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for defining a sequence of animations for changing visible and non-visible values of objects. One or more programmatic calls is received, the calls including animations and sequencing for their performance. Consecutive frames of the animations are displayed according to the animations and the sequencing defined in the programmatic calls. Non-displayed properties of the objects in the animations are changed in coordination with the displaying of the consecutive frames.
