Certain embodiments involve a graphics manipulation application using brushstroke parameters that include a maximum alpha-deposition parameter and a fractional alpha-deposition parameter. For instance, the graphics manipulation application uses an alpha flow increment computed from the maximum alpha-deposition parameter and the fractional alpha-deposition parameter to compute an output canvas color. In some embodiments, if the current canvas opacity exceeds or equals the maximum alpha-deposition parameter, the current canvas opacity is selected as the output canvas opacity. Otherwise, the graphics manipulation application computes the output canvas opacity by increasing the current canvas opacity based on the alpha flow increment. The graphics manipulation application updates a canvas portion affected by a brushstroke input to include the output canvas opacity and the output canvas color.

Provided is a sample image that is close to an actual object. The following steps 1 to 5 are performed. (Step 1) Image data (A0) corresponding to an image (A) is converted to acquire image data (A1). (Step 2) Image data (B0) corresponding to an article (B) is converted to acquire image data (B1) corresponding to a surface state of a region of the article (B) on which the image (A) is printed. (Step 3) Image data (A2) is acquired from the image data (A1) and the image data (B1). (Step 4) The image data (A2) is converted to acquire image data (A3). (Step 5) Image data (C0) corresponding to a product (C) is acquired from the image data (A3) and the image data (B0).

A display apparatus according to an embodiment of the present technology includes a display section, an acquisition section, and an image generator. The display section includes a display that has a cylinder-like body and on which an output image is displayed. The acquisition section acquires pieces of direction information that respectively indicate directions of respective users of a plurality of users as viewed from the display. The image generator generates the output image on the basis of the pieces of direction information such that pieces of information that respectively correspond to the users of the plurality of users are presented in the respective directions of the users of the plurality of users.

Provided are an ink data generation apparatus, an ink data generation method, and an ink data generation program that are capable of improving ease of handling ink data when or after metadata is generated. An ink data generation apparatus performs a determination as to an inclusion relation between a first set and a second set by comparing stroke elements of first set data and stroke elements of second set data using the first set data and the second set data. The ink data generation apparatus generates first metadata for the first set described in a form that varies in accordance with a result of the determination.

Using a computer-implemented intermediary by which contouring performed by two participants, such as two physicians, can be compared. First, contouring performed by each participant can be compared to contouring performed by the intermediary. Then, by way of the common intermediary and a transitive analysis, contouring performed by each participant can be compared.

The present invention provides an image composition method, an image composition device, and a recording medium that enable rapid and easy designation of correspondence points and image composition based on the designated correspondence points. In an image composition method according to an aspect of the invention, in a case where all of a plurality of images are unable to be composed into one image, a plurality of images are divided into composable image groups, whereby correspondence points may be designated for one image group and another image group (that is, image groups not subjected to automatic composition) without need of designating correspondence points for all images. A plurality of images are displayed on a display device by composable image group, whereby it is possible to allow ascertainment of image groups for which correspondence points are designated. With the image composition method, it is possible to rapidly and easily perform designation of correspondence points and image composition based on the designated correspondence points.

Aspects of subject technology provide systems and methods for electronic drawing with handwriting recognition. An electronic device may include one or more processors configured to receive a modification input to an object rendered on a display, and to perform a first re-rendering of the object on the display based on the modification input. The one or more processors may further be configured to generate at least one polygon-based representation of the object based on the modification input, and to perform, based on the at least one polygon-based representation, a second re-rendering of the object on the display.
