The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just
Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
Embodiment one
Fig. 1 is a kind of flow chart of the method for display barrage data that the embodiment of the present invention one provides, and the present embodiment can fit
The case where for showing barrage data when playing multi-medium data, this method can be held by the device of display barrage data
Row, the device can be configurable in computer equipment by software and or hardware realization, as mobile phone, tablet computer, intelligence are worn
The mobile terminals such as equipment are worn, and, the immobile terminals such as PC, TV, this method specifically comprises the following steps:
S101, multi-medium data is played.
In the present embodiment, multi-medium data may include video data, audio data, image data, text, etc..
It should be noted that the meaning of multi-medium data is also different in different scenes, the present embodiment to this not
It limits.
For example, the video data can be live data in the scene of live streaming, and in the scene of program request, the video counts
According to can be film, TV play etc..
In another example the audio data can be sound novel, which can be novel in the scene of novel.
In another example the image data can be stock exchange index figure in the scene of finance and economics.
Under normal circumstances, multi-medium data stores in the server, user oriented, if what user provided in computer equipment
UI (User Interface, user interface) is operated, the multi-medium data in request server, and server then can will be more
Media data is sent to computer equipment, and computer equipment calls the player plays multi-medium data.
By taking the scene of live streaming as an example, mountable independent live streaming applies, has answering for live streaming component in computer equipment
With or the application such as browser, depending on the user's operation, such as click the thumbnail of some direct broadcasting room, input the link of some direct broadcasting room
Deng using the load request for sending direct broadcasting room to live streaming platform.
Live streaming platform receives the load request, and responds the load request, by the data of direct broadcasting room be sent to the application into
Row display, also, live data is sent to the application, to be played out in the direct broadcasting room.
S102, character string is received.
For the multi-medium data, other users can make comments, if these comments meet specification, can be exchanged into character
String, and it is stored in server.
In the present embodiment, server can be while sending multi-medium data to computer equipment, by the multimedia number
According to subsidiary character string, it is also sent to computer equipment together.
Wherein, which includes one or more character strings, the word of character string in character string for indicating barrage data
Symbol is for indicating the element in barrage data.
S103, type matrix is determined.
In the present embodiment, the element for generating barrage data, such as text, expression can be regarded as an X-Y scheme
Shape describes the binary code string of the dot matrix of an element, the referred to as type matrix of the element with one element of matrix representation.
For type matrix, the settable information for dot matrix typesetting, for example, baseline (origin), the size (gray scale of dot matrix
Figure size, width+3/4*height*bit), specify the point coordinate for surrounding the minimum matrix upper left corner of font architecture completely
(BeginX, BeginY), actual size (width, height), etc..
For example, " Chinese " as shown in Figure 2 A and the expression for being used to express indignation as shown in Figure 2 B, use 16 × 16 point
Gust, every bit is indicated using bit (Bit) in type matrix, if it is 1 (point of full-filling black), then illustrates have herein
Point, if 0 (point of non-full-filling black), then explanation does not have, in this way, the Chinese character of 16 × 16 dot matrix needs 16*16/8 in total
=32 byte representations.
In this example, the order of representation of type matrix are as follows: first from left to right, then from top to bottom, that is, first draw upper left 8
It is a, then be 8 points in upper right side, followed by 8, second row left side point, 8, the right point, and so on, it draws 16 × 16 full
Point.
Furthermore, can in the mapping relations established in computer equipment between element (with character representation) and type matrix,
The type matrix is for recording element expressed by the character.
For the mapping relations of the elements such as text and type matrix, the character library in operating system has preset mapping relations, can
The mapping relations are multiplexed, for the mapping relations of the elements such as expression and type matrix, a manager can be independently arranged and be managed.
Furthermore, example of the Chinese character as text, Chinese character are generally stored inside in the Chinese character base of operating system, commonly
Chinese character base has HZK16, HZK24, HZK32 etc., i.e. dot matrix is 16*16,24*24,32*32 etc..Dot matrix small scale, resolution ratio is poor,
Unsightly, the word and the complex form of Chinese characters of some strokes complexity are difficult to indicate font, but required memory capacity is small, it is easy to accomplish；Dot matrix rule
Mould is big, then high resolution, and font is beautiful, but required memory capacity is big.
For expression, expression can be converted to type matrix, it is identical in the dot matrix of type matrix and the dot matrix size of text, alternatively,
The size of the dot matrix of type matrix is the mean size of the dot matrix of the scintilla, and limits the color of each point in the dot matrix of type matrix, makes
It is managed with expression manager.
After computer equipment receives character string, each character that parsing character string includes is looked into the mapping relations
Look for the corresponding type matrix of the character.
For barrage data, type matrix is used to record the element in barrage data.
S104, the type matrix is loaded in an image data.
In the concrete realization, in the memory of computer equipment, a frame image data is generated, it is corresponding to calculate each character
Type matrix reads the lattice information of type matrix according to this address, typesetting is carried out in the image data in the storage address of memory.
Using the text in FreeType as the example of type matrix, after rendering type, the bitmap of generation is just exactly text
Size, so several parameters for typesetting are as follows needing to carry out typesetting to it later on bitmap copy to image data:
Metrics.height indicates the height of every a line, generates after corresponding text size is arranged, every a line
Text all do not exceed this range.
Metrics.ascender indicates the height on top, while can also calculate the height of baseline, for baseline
The alignment of character.
Metrics.horiAdvance indicates the width of each text.
Bitmap.pitch indicates the pixel quantity of the every row of bitmap generated.
Bitmap.rows indicates the line number of the bitmap generated.
Bitmap_left, the distance of expression bitmap to text left margin.
Bitmap_top, the distance of expression bitmap to text coboundary.
If if being replication orgin with the upper left corner (x, y), in order to align text, then copy-point should be:
Pos_x=x+bitmap_left
Pos_y=y+ascender-bitmap_top
S105, using described image data as barrage data, display on the multi-medium data.
In practical applications, when playing multi-medium data, it can be taken out from memory on suitable opportunity and be loaded with type matrix
Image data, be shown on multi-medium data.
By taking the scene of live streaming as an example, as shown in figure 3, computer equipment calls video player to play live data, connecing
The character string for receiving live streaming platform, that is, can be exchanged into barrage data, real-time display is on the picture of live data.
The embodiment of the present invention plays multi-medium data, receives character string, the character of the character string is for indicating barrage data
In element, determine the type matrix for recording the element, the type matrix loaded in an image data, using image data as barrage
Data are shown on multi-medium data, as a whole by the element in barrage data, figure are loaded onto the form of type matrix
As to show as barrage data, avoiding and carrying out cutting to barrage data in data, wash with watercolours integrally can be carried out to barrage data
Dye, without repeatedly occupying the component for rendering, operand is few, reduces resource cost.
Embodiment two
Fig. 4 is a kind of flow chart of method for showing barrage data provided by Embodiment 2 of the present invention, before the present embodiment
Based on stating embodiment, further increase determining type matrix, in image data load type matrix processing operation.This method is specifically wrapped
Include following steps:
S401, multi-medium data is played.
S402, character string is received.
Wherein, the character of character string is used to indicate the element in barrage data.
If S403, the character do not include placeholder, it is determined that the character expresses text, searches and records the text
Type matrix.
If S404, the character include placeholder, it is determined that the character expresses expression, searches the word for recording the expression
Mould.
In the present embodiment, the element in barrage data includes text and/or expression.
General coded representation, such as Unicode16 can be used in character string, for text, can be converted directly into corresponding volume
Code, can be according to the specification of coding, customized placeholder for expression.
For example, the expression of an expression " laughing at ", customized escape character is "/{ dx ", and placeholder is " 0xE000 ", it is assumed that one
A barrage data are " ' laughing at ' AA ", and being converted to character string is "/{ dxAA ", then the character string in memory is " 0x2f 0x7B 0x64
0x78 0x41 0x41 ", the character string in memory is " 0xE000 0x41 0x41 " after treatment.
Therefore, computer equipment parses the character in character string, judges whether character is to account for after receiving character string
Position symbol searches the corresponding type matrix of the placeholder (expression) if it is, determining the character representation expression from expression manager,
If it is not, then determining the character representation text, pass through FreeType/Window Api GetGlyphOutline/
The libraries such as IDWriteFontFace or interface search the corresponding type matrix of the character (text).
Furthermore, in order to be adapted to different texts, keep the consistency of barrage data can for the same expression
Design the type matrix of a plurality of different sizes (such as height, width).
When searching the type matrix for recording espressiove, it may be determined that the first size of the type matrix of text is (the such as first height, first wide
Degree etc.), so that it is determined that the second size (such as height, width) being adapted to first size.
For example, the average value (such as average height, mean breadth) of first size is calculated, with closest to the ruler of the average value
It is very little to be used as the second size.
In the multiple type matrixes for recording the expression, the type matrix for meeting second size is searched.
S405, creation can accommodate the image data of the type matrix.
In the memory of computer, a bitmap can be created, as image data, for accommodating all type matrixes.
In the concrete realization, the first width and the first height for determining all type matrixes, create image data to this, wherein
Image data has the second width and the second height, the second width the sum of more than or equal to first width, the second height be greater than or
Equal to the first all height.
In general, the size of the image data can be slightly larger than all type matrixes, to economize on resources.
Therefore, a deviant can be increased on the basis of the sum of first width, the second width is obtained, maximum first
Increase another deviant on the basis of height, obtains the second height.
S406, position of the type matrix in described image data is determined.
Each character has had sequence in character string, on the image data according to the sequence by the corresponding type matrix of each character
Typesetting, so that it is determined that coordinate of each type matrix in image data, as its position.
S407, the color for determining type matrix.
For expression, when designing its type matrix, the color of its defined dot matrix, is recorded in expression manager together with type matrix
In.
Therefore, if the element in barrage data is expression, the face of the type matrix can be directly inquired from expression manager
Color.
For text, color index table can be preset, grey level and transparency, color are recorded in the color index table
Between mapping relations.
In one example, for color by taking rgb space as an example, the partial information in color index table is as follows:
| Level | Index | Alpha | Red | Green | Blue |
| 5 | 3 | 153 | 60 | 38 | 120 |
| 65 | 10 | 39 | 39 | 9 | 31 |
| 255 | 200 | 200 | 78 | 50 | 156 |
Wherein, Level indicate grey level, Index indicate index value, dot matrix gray values (value range be 0~
Level-1), Alpha indicates transparency.
In this example, the color of some Index indicates:
ShowColor [Index]=((TxColor-BkColor)/Level) * Index
Wherein, TxColor indicates text color (including red value Red, green value Green, blue valve Blue),
BkColor indicates background color color (including red value Red, green value Green, blue valve Blue).
Therefore, if the element in barrage data is text, the grey level of text can be determined, in color index table
Determine the color of grey level mapping, the color as type matrix.
It, can be by issuing the user setting of the text for the color of text (type matrix), it can also be by browsing the text
User setting, etc., the present embodiment are without restriction to this.
S408, preset texture interface is called to carry out texture mapping to described image data, using as barrage data, display
On the multi-medium data.
One group of component, such as DirectX are configured in computer equipment, which the multimedia for being built in hardware can be used to add
Fast device function.
The component provides one or more texture interfaces, if TEXTURE1D is (for indicating the texture resource class of 1D data
Type), TEXTURE2D (for indicating the texture resource type of 2D data), TEXTURE3D (for indicate 3D data texture provide
Source Type), texture interface is commonly used in one certain types of image data of management.
Image data is written in the corresponding slot of texture interface, is rendered, is shown in the components such as incoming Sharder
