A method implemented by a transmission device to communicate with multiple reception devices that respectively share a drawing area with the transmission device is provided. The transmission device transmits to the multiple reception devices vector-data ink data representative of traces of input operation detected by an input sensor of the transmission device. The method includes: (a) an ink data generation step of generating fragmented data of a stroke object, wherein the stroke object contains multiple point objects to represent a trace formed by a pointer, the fragmented data being generated per defined unit T, and generating a drawing style object; (b) a message formation step of generating messages including the drawing style object and the fragmented data; and (c) a transmission step of transmitting the messages.

An input display device includes: a processor to execute a program; and a memory to store the program which, when executed by the processor, results in performance of steps including: receiving an input of a track by a receiving unit; generating a track image showing the track; acquiring a character string; and displaying the character string acquired in the acquiring to be superimposed on the track image. When the character string is acquired in the acquiring before the track image is generated, the displaying the character string is stood by.

An optimizing method, a system, and a smart device to display circular patterns smoothly are provided by the present disclosure. It gets coordinate values of all points on the circular pattern. It calculates respective transparency compensation values of two adjacent points with respect to a corresponding one of the points to any coordinate in an X-axis direction and a Y-axis direction of the circular pattern using a maximum limit of the transparency as a benchmark, and then calculates a transparency compensation value of the corresponding one of the points using the transparency compensation values of the two adjacent points. Finally, it redraws all points of the circular pattern based on the calculated transparency compensation value and the RGB parameters of the corresponding one of the points.

Multi-graphic display method and computer-readable storage medium are disclosed. In the multi-graphic display method, a processor is used to execute instructions to perform the step of, within a display window, determining the position of each financial graphic, determining a plurality of rectangular sub-regions in the display window so that the financial varieties of the financial graphics contained in the single rectangular sub-region are the same, and setting the financial characteristics of each financial graphic, and setting a financial variety of financial graphics within each of the rectangular sub-regions. In the case where two or more rectangular sub-regions within the display window contain a plurality of periodic financial graphics, the financial characteristics of at least two of the periodic financial graphics between at least two of the rectangular sub-regions are identical.

Automatic font synthesis for modifying a local font to have an appearance that is visually similar to a source font is described. A font modification system receives an electronic document including the source font together with an indication of a font descriptor for the source font. The font descriptor includes information describing various font attributes for the source font, which define a visual appearance of the source font. Using the source font descriptor, the font modification system identifies a local font that is visually similar in appearance to the source font by comparing local font descriptors to the source font descriptor. A visually similar font is then synthesized by modifying glyph outlines of the local font to achieve the visual appearance defined by the source font descriptor. The synthesized font is then used to replace the source font and output in the electronic document at the computing device.

A method of rasterising a line in computer graphics determines whether the line's start and/or end is inside a diamond test area within the pixel. If the end is not inside and the start is inside, the pixel is drawn as part of the line. If neither the start nor the end of the line are inside, it is determined whether the line crosses more than one extended diamond edge and if so, it is further determined (i) whether an extended line passing through the start and end is substantially vertical and touches the right point of the diamond area, (ii) if the extended line touches the bottom point of the diamond area, and (iii) whether the extended line is on a same side of each point of the diamond area. If any of (i), (ii) and (iii) is positive, the pixel is drawn as part of the line.

One variation of a method includes: accessing a handwriting sample comprising a set of user glyphs handwritten by a user; for each character in a set of characters, identifying a subset of user glyphs corresponding to the character in the handwriting sample, characterizing variability of a set of spatial features across the subset of user glyphs, and storing variability of the set of spatial features across the subset of user glyphs in a character container corresponding to the character; and compiling the set of character containers into a handwriting model for the user. The method further includes: accessing a text string comprising a combination of characters in the set of characters; for each instance of each character in the text string, inserting a set of variability parameters into the handwriting model to generate a synthetic glyph representing the character; and assembling the set of synthetic glyphs into a print file.

An image processing method includes: recognizing a target contour of a target object in a target image collected at a current moment determining, in the target contour, a starting contour point corresponding to a starting contour position, a final contour point corresponding to a final contour position, and a split contour point corresponding to the current moment taking a line segment composed of contour points between the starting contour point and the split contour point in the target contour as a first line segment, and taking a line segment except the first line segment in the target contour as a second line segment rendering the first line segment according to a first color, and rendering the second line segment according to a second color.

According to an embodiment, a computer-implemented method for generating an edge curve to facilitate manufacture of at least a portion of a dental device is disclosed. The method includes identifying at least one tooth reference point for each of at least two teeth on a dental model; identifying at least one offset point corresponding to each of the at least one tooth reference points such that the at least one offset point is on a gingival surface of the dental model and located outside an interproximal area; and generating the edge curve by connecting the offset points such that the edge curve is outside the interproximal area and on the gingival surface.

A system and method for tracing polygons in a drawing source file. The method includes extracting vector imagery from the source file, creating a planar representation of the vector imagery as a plurality of lines, filtering the plurality of lines to create simplified line art, morphologically dilating the simplified line art to generate a polygonal approximation, calculating geometric difference between the source file canvas bounds and the polygonal approximation to identify contracted polygons, morphologically dilating the contracted polygons to create visual polygons, and filtering the visual polygons according to one or more geometric parameters to identify salient polygons.
