Embodiment
The invention provides a kind of method for generating captions that uses filter, as shown in Figure 2, may further comprise the steps:
Step s210, the character die calls filter is also exported the type matrix rendering result;
Step s220, the direct mixed processing output of described type matrix rendering result and literal blended data;
Step s230, described blended data is called filter execution literal and is played up operation.
Below in conjunction with specific embodiment the present invention is described in further detail.
The invention provides a kind of method for generating captions that uses filter, as shown in Figure 3, the literal rendering effect is with the distortion literary composition example of literal shape.
Step s310 obtains literal distortion type matrix;
Obtain before the literal distortion type matrix, the user needs at first literal to be stored in the internal memory.
The user can be to import and store in the internal memory by the mode of keyboard input to the storage mode of literal, also can be the stickup of duplicating to data with existing in the internal memory.
Step s320, literal distortion character die calls filter;
Literal distortion type matrix sends call request to filter;
Filter responds this request, and receive above-mentioned literal distortion type matrix and play up processing, and output type matrix rendering result.
Step s330, type matrix rendering result and literal carry out mixed processing;
Above-mentioned type matrix rendering result and literal directly carry out mixed processing, form to have the blended data that is different from above-mentioned literal and type matrix rendering result, and this blended data has new transmission means and data format.
Step s340, above-mentioned blended data is called filter;
Above-mentioned blended data sends call request to filter;
Filter responds this request, blended data is carried out literal play up operation, forms the literal with distorted shape.
Filter to above-mentioned blended data play up EO after, the literal shape after the distortion is sent to display screen, generate the caption rendering effect that the user needs.
The invention provides a kind of method for generating captions that uses filter, as shown in Figure 4, the literal rendering effect increases progressively the literary composition example with text color.
Step s410 obtains text color and increases progressively type matrix;
Obtain text color and increase progressively before the type matrix, the user needs at first literal to be stored in the internal memory.
The user can be to import and store in the internal memory by the mode of keyboard input to the storage mode of literal, also can be the stickup of duplicating to data with existing in the internal memory.
Step s420, text color increase progressively the character die calls filter;
Text color increases progressively type matrix and sends call request to filter;
Filter responds this request, and receive above-mentioned text color and increase progressively type matrix and play up processing, and output type matrix rendering result.
Step s430, type matrix rendering result and literal carry out mixed processing;
Above-mentioned type matrix rendering result is directly mixed with literal and is handled, and forms to have the blended data that is different from above-mentioned literal and type matrix rendering result, and this blended data has new transmission means and data format.
Step s440, above-mentioned blended data is called filter;
Above-mentioned blended data sends call request to filter;
Filter responds this request, blended data is carried out literal play up operation, forms the literal that color increases progressively.Filter to above-mentioned blended data play up EO after, the literal that color is increased progressively sends to display screen, generates the caption rendering effect that the user needs.
By adopting method for generating captions provided by the invention, can make filter by using the abundant rendering effect of type matrix to literal, realization is played up the literal shape, comprises size, stretching, the distortion operation of literal at least; Realization comprises at least according to the font of literal and regulates color the operation of text color, the gradual change of text color, increase progressively, successively decrease, outstanding operation.
