Abstract: Various aspects of the subject technology relate to systems, methods, and machine-readable media for reverse search with manual composition. A system generates a first search result associated with a forward image search that is responsive to a search query from a client device, and each image in the first search result respectively includes a base layer that includes a representation of a first composition for the image. The system may receive user input indicating a target composition defined by the base layer of at least one image from the first search result and an object layer that indicates adjustments to the first composition of the base layer, and generates a second search result using the target composition. The second search result includes second images that respectively include a representation of a second composition that corresponds to the target composition. The system provides the second search result to the client device.

Abstract: Methods for providing in-browser perspective manipulation are provided. In one aspect, a method includes executing, in a web browser, an image editing application retrieved from a remote server. The method also includes providing for display, in a user interface of the image editing application, a background and an image. The method also includes modifying anchors of the image in response to user input. The method also includes determining an indicator for supporting hardware graphics acceleration in the web browser. When the indicator is true, the method includes calling a 3D perspective transformation function on the image based on the modified anchors. When the indicator is false, the method includes a 2D approximation that divides the image into smaller units for affine transformations, which are then recombined into the transformed image. The method also includes compositing an output image comprising the transformed image in front of the background.
