Abstract

PROBLEM TO BE SOLVED: To enable a user to easily edit text.SOLUTION: An information processing device comprises: determination means which determines whether text includes an animation glyph; and change means which, when the determination means determines that the text includes an animation glyph, changes a state of the animation glyph when the text is in an editing state.

Description

  The present invention relates to an information processing apparatus, an information processing method, and a program.

Conventionally, in editing text, vertical bars, chevron shapes, and rectangles have been displayed as carets in order to feed back the character insertion position to the user. The caret allows the user to grasp where the input character is inserted and which character is deleted when the delete operation is performed. On the other hand, the user was able to move the caret with a keyboard, mouse, touch operation, or the like.
A technique for changing the display of the cursor not only at the insertion position but also according to the enlargement / reduction / rotation of the character corresponding to the insertion position is known as a conventional technique (Patent Document 1).
On the other hand, a specification that uses the expressive power of SVG (Scalable Vector Graphics) for character display itself is also being studied. In addition to vector information, SVG can also describe color information and animation information, and each character can have a plurality of color information, an animation that expands and contracts, and the like.

<Embodiment 1>
FIG. 2 is a diagram illustrating an example of a software configuration of the text display apparatus according to the first embodiment.
Hereinafter, an example of information processing according to the present embodiment will be described with reference to the flowchart of FIG.
The drawing information storage unit 203 stores information related to drawing.
The text analysis unit 204 determines whether the text to be drawn is in an editing state based on the information stored in the drawing information storage unit 203 (step S301). If the text analysis unit 204 is in the editing state, the process proceeds to step S302; otherwise, the process proceeds to step S315. For example, the text shifts to an editing state by a user's keyboard operation, mouse operation, or touch operation, and a caret is displayed in the editing state.
The text analysis unit 204 checks whether the text includes an animation glyph (step S302). If the text analysis unit 204 includes the text analysis unit 204, the process proceeds to step S303. Otherwise, the text analysis unit 204 proceeds to step S315. The text analysis unit 204 determines whether it is an animation glyph from, for example, header information of a font for drawing text. Alternatively, the text analysis unit 204 may determine whether the font glyph information includes animation information. Alternatively, the text analysis unit 204 may determine whether or not the text includes a specific character code. Or the text analysis part 204 may determine from the information which an application provides. Or the text analysis part 204 may determine based on a user's instruction | indication.

The glyph analysis unit 205 acquires the caret information in the text from the drawing information storage unit 203, and analyzes the glyph information before and after the caret (step S303).
The glyph analysis unit 205 checks whether the glyphs before and after the caret include animation information (step S304). The glyph analyzing unit 205 proceeds to step S305 if included, or proceeds to step S315 if not included. For example, when the glyph information is described in SVG, the glyph analysis unit 205 determines whether the glyphs before and after the caret include animation information based on whether there is an element related to the animation. As a result of the analysis, if it is determined that no animation is performed while the user is editing the text, the glyph analysis unit 205 may proceed to step S315.
In the present embodiment, whether the glyphs before or after the caret include animation information is checked. However, the glyph analysis unit 205 may check whether glyphs within a predetermined character before and after the caret include animation information. .

In the present embodiment, the character shape and the animation information are described in SVG as shown in FIG. A character shape is defined by the <path> element, and an animation of the character is defined by <animateTransform>. The relationship with characters is specified by the id attribute. When the text includes animated characters, the text display changes as shown in FIG. 5 with time.
In FIG. 5, “A” and “B” are characters having no animation, and “☆” is a character having animation information. “☆” moves to the upper right while rotating from (a) in FIG. 5 to (b) in FIG. 5 and from (b) in FIG. 5 to (c) in FIG. 5. ) To FIG. 5 (b) and FIG. 5 (b) to FIG. 5 (a).
The glyph analysis unit 205 stores the current glyph state in the glyph information storage unit 206 (step S305). The glyph information to be stored is, for example, glyph position, shape, and color information.
The calculation unit 207 acquires glyph animation information from the glyph analysis unit 205 (step S306).
The calculation unit 207 calculates the time point when the glyph comes to the position corresponding to the caret from the animation information of the glyph (step S307). The corresponding position is the position that is placed when the glyph is a non-animated glyph. For example, in horizontal writing, it is before and after the caret.

The calculation unit 207 determines whether the time point at the position corresponding to the caret can be calculated (step S308). If possible, the calculation unit 207 proceeds to step S311; otherwise, the calculation unit 207 proceeds to step S309. For example, the calculation unit 207 determines that the time point cannot be calculated when the glyph does not have animation information that comes before and after the caret.
The calculation unit 207 acquires the affine matrix of the glyph in the initial state (step S309). The initial state is a state immediately after the start of drawing, for example. In the present embodiment, the text display device 101 manages the position information of the glyph by affine transformation, but may manage it by two-dimensional coordinates or an index.
The calculation unit 207 calculates the affine transformation so that the initial state glyph is located at the position corresponding to the caret (step S310). In the present embodiment, the calculation unit 207 calculates an affine transformation including rotation and enlargement / reduction in addition to translation so as to be the same height as the glyph that is not animated.
The glyph operation unit 208 updates the position information of the glyph based on the calculation result of the calculation unit 207 and places it at the position corresponding to the caret (step S311). Further, the glyph operation unit 208 may update the glyph shape information so as to correspond to the caret.

The glyph analysis unit 205 acquires glyph color information from the drawing information storage unit 203 (step S312). In the present embodiment, the color information is represented by 8-bit alpha, red, green, and blue. Color transparency is controlled by alpha.
The glyph analysis unit 205 confirms the alpha of the color information at the time of drawing and determines whether it is transparent (step S313). The glyph analysis unit 205 proceeds to step S314 if transparent, and to step S315 otherwise.
The glyph operation unit 208 changes the alpha of the glyph to opaque (step S314). In the present embodiment, the glyph analysis unit 205 makes the alpha of the glyph opaque, but it may be changed to translucent. The glyph operation unit 208 may calculate the degree of translucency based on the animation information.
The drawing unit 202 draws the glyph on the display unit 106 (step S315).
The drawing unit 202 draws the caret on the display unit 106 (step S316). In the present embodiment, the drawing unit 202 draws the caret after drawing the glyph, but may draw the glyph after drawing the caret. In this embodiment, the caret is represented by a vertical bar as shown in FIG. 6A, but may be a rectangle, a dotted line, or a mountain.

The drawing result of the text in the editing state is as shown in FIG. In FIG. 6, “A” and “B” are characters having no animation, and “☆” is a character having animation information. The caret is represented by a vertical bar. The text display at time 0 is as shown in FIG. If there is no animation character before or after the caret, “☆” continues the animation as shown in FIG. When the caret moves to the right, animation characters exist before and after the caret, so the glyph is placed at a position corresponding to the caret, so the animation of “☆” stops and becomes as shown in FIG.
When the text is no longer in the editing state (when the caret is separated), for example, the glyph operation unit 208 proceeds to step S318 (step S317).
The glyph operation unit 208 acquires the glyph information stored from the glyph information storage unit 206 and resets the glyph information (step S318).

By performing the information processing described above, even if the characters are animated text, the animation is suppressed around the caret, and the user can easily edit the text.
In this embodiment, the text display apparatus 101 showed the example which suppresses the animation around a caret. However, the text display device 101 may suppress animations other than the vicinity of the caret during text editing.

In addition, description is abbreviate | omitted about the process which is the same as Embodiment 1, and a different point from Embodiment 1 is mainly demonstrated.
The caret information storage unit 701 acquires caret information in the text from the drawing information storage unit 203. The caret information is, for example, the caret shape, blinking interval, and color information. The caret information storage unit 701 stores the acquired caret information (step S801).
In this embodiment, a caret displayed for a stationary character is called a main caret, and a caret displayed corresponding to an animated glyph is called a glyph caret. Only the main caret is displayed for stationary characters, and the main caret and glyph caret are displayed for animated glyphs. However, only the glyph caret may be displayed for animated glyphs.

The glyph analysis unit 205 obtains an inclusion rectangle of the glyph to be animated (step S802). In this embodiment, the inclusion rectangle is the smallest rectangle that encloses a path formed of horizontal and vertical sides with respect to the coordinate system. Alternatively, the font or glyph may have information on the inclusion rectangle.
The calculation unit 207 calculates the position of the glyph caret (step S803). In the present embodiment, the glyph caret is displayed on the left or right side of the containing rectangle in the case of horizontally written text. When the caret moves from left to right, the caret is first displayed on the left side of the containing rectangle, and the next movement is displayed on the right side.
The caret operation unit 702 sets the main caret to a dotted line (step S804). Although the dotted line is used in the present embodiment, the caret operation unit 702 may change the color information. Alternatively, the caret operation unit 702 may change the line width. Alternatively, the caret operation unit 702 may update the shape information of the caret. The caret operation unit 702 may determine what kind of change is performed according to the animation information of the glyph.
The caret operation unit 702 sets the glyph caret to a dotted line (step S805).

The drawing unit 202 draws the main caret (step S806).
The drawing unit 202 draws the glyph caret (step S807).
The drawing result of the text in the editing state is as shown in FIG. In FIG. 9, “A” and “B” are characters having no animation, and “☆” is a character having animation information. The caret is represented by a vertical bar. The text display at time 0 is as shown in FIG. If there is no animation character before or after the caret, “☆” continues the animation as shown in FIG. When the caret moves to the right, animated characters will appear before and after the caret, so the main caret is displayed as a dotted line, and the glyph caret is displayed on the left side of “☆” that continues the animation. c).
The caret operation unit 702 deletes the glyph caret (step S808).
The caret operation unit 702 acquires the caret state from the caret information storage unit 701 and restores the caret state (step S809).
