Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 1 shows the flow process of the character displaying method of the multimedia file that the embodiment of the invention provides.
In step S101, obtain the data bitmap of font to be shown.
The embodiment of the invention is through the font drawing engine; Freetype2 for example obtains the data bitmap of font to be shown, wherein; Each pixel in the data bitmap is formed, and is indicated the transparency of this pixel through the α value of each pixel by r, g, three kinds of colors of b.
In step S102, obtain the color of character contour according to the corresponding color of said data bitmap, wherein, the color that the color of said character contour and said data bitmap are corresponding is different;
Preferably, the color of the said character contour color corresponding with said data bitmap is opposite, certainly, also other different modes can be arranged, if make color that data bitmap is corresponding and character contour colouring discrimination obviously, do not enumerate one by one here.
Wherein, according to data bitmap corresponding color negate to obtain the algorithm of color of character contour following:
The r value of the r value=0xff-data bitmap of character contour;
The g value of the g value=0xff-data bitmap of character contour;
The b value of the b value=0xff-data bitmap of character contour;
The α value of the α value=0xff-data bitmap of character contour.
In step S103, the character contour of said font to be shown is drawn according to the color of said character contour.
When drawing, the embodiment of the invention is also drawn said font to be shown according to the color of said character contour, promptly whole font to be shown and profile thereof is drawn.
Wherein, the character contour of said font to be shown is: on the upper left side of said font display position to be shown, and the upper right side, lower left, lower right are drawn font to be shown respectively and are formed.
After getting access to the color of character contour, replace the corresponding color of data bitmap of font to be shown with the color of character contour, the character contour of said font to be shown is drawn.
The coordinate that font pixel for example to be shown is drawn be A (x, y), then:
It is that (x-1 y+1), sees also Fig. 2 to B that the position is drawn on the upper left side;
It is that (x+1 y+1), sees also Fig. 3 to C that the position is drawn in the upper right side;
It is that (x-1 y-1), sees also Fig. 4 to D that the position is drawn in the lower left;
It is that (x+1 y-1), sees also Fig. 5 to E that the position is drawn in the lower right;
The effect that whole font to be shown and profile thereof are drawn sees also Fig. 6;
In step S104, said font to be shown is drawn according to the color that said data bitmap is corresponding.
(x y) draws literal, is combined in the drafting of treating the display text profile among the step S103, promptly obtains retouching the limit effect, sees also Fig. 7 at former font coordinate to be shown with the color of data bitmap.
In step S105, the font after drawing is shown.
Fig. 8 shows the structure of the character display apparatus of the multimedia file that the embodiment of the invention provides.Wherein, said device comprises data bitmap acquisition module 81, profile color acquisition module 82, profile color drafting module 83, font drafting module 84 and font display module 85.
Wherein, data bitmap acquisition module 81 obtains the data bitmap of font to be shown.
In the embodiment of the invention, data bitmap acquisition module 81 obtains the data bitmap of font to be shown through connective word volume drawing engine through the font drawing engine.
Profile color acquisition module 82 obtains the color of character contour according to the corresponding color of said data bitmap, and wherein, the color that the color of said character contour and said data bitmap are corresponding is different.
In the embodiment of the invention, for outstanding font display effect, the color of the character contour that the is obtained color corresponding with said data bitmap is opposite.
Profile color drafting module 83 is drawn the character contour of said font to be shown according to the color of said character contour;
Wherein, the character contour of said font to be shown is: on the upper left side of said font display position to be shown, and the upper right side, lower left, lower right are drawn font to be shown respectively and are formed.
Simultaneously, font drafting module 84 is drawn said font to be shown according to the color of said character contour.
Afterwards, font drafting module 84 is drawn said font to be shown according to the corresponding color of said data bitmap.
At last, the font after font display module 85 will be drawn shows.
The embodiment of the invention also provides a kind of multimedia play equipment, and said equipment comprises the character display apparatus of the multimedia file that the embodiment of the invention provides, and in view of this device has detailed description at preceding text, repeats no more here.
The embodiment of the invention is through obtaining the color of character contour; Wherein, The color of said character contour is different with the color of font data bitmap to be shown, according to the color of character contour the character contour of said font to be shown is drawn, afterwards; According to the corresponding color of font data bitmap to be shown said font to be shown being drawn the back shows; Well solve because the main color of video is close or identical with the Show Color of plug-in captions, the unsharp problem of plug-in captions that causes brings great convenience to user's viewing.
Should be understood that, concerning those of ordinary skills, can improve or conversion, and these improvement and conversion all should belong to the protection range of accompanying claims of the present invention according to above-mentioned explanation.
