Description
Technical field
The present invention relates to the synthesis technical fields more particularly to a kind of synthetic method of sound PNG pictures of picture and audio
And synthesis system.
Background technology
With the development of multimedia technology, user is no longer only limitted to static images to the demand of displaying, but increasingly inclines
It is played simultaneously with audio in picture, therefore the synthetic technology of picture and audio is come into being.The existing picture of existing market and
Audio composite software is very more, such as：In graphic detail, sony vegas, AE etc., but picture and audio are closed through these softwares
Become video after, the file of synthesis is excessive or synthesis after PNG pictures cannot be known by Android or ios compilers
It does not apply, the PNG pictures or file after synthesis cannot be reduced by dynamic analysis.
The content of the invention
The technical problems to be solved by the invention are：A kind of synthetic method and synthesis system of sound PNG pictures, energy are provided
It is enough effectively to solve the problems, such as that file is excessive, be compiled and cannot be reduced after synthesis.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of synthetic method of sound PNG pictures, including：
Obtain PNG pictures and audio address date；
The PNG pictures are parsed, obtain all data blocks of the PNG pictures, all data blocks include image knot
Beam data block；
It adds the audio address date to described image and terminates data block；
Terminate data block to the image for being with the addition of audio address date to verify；
All data blocks in addition to terminating data block except image after verifying successfully and it is with the addition of audio number of addresses
According to video data block preserve successively into same file, generate sound PNG pictures.
Another technical solution provided by the invention is：
A kind of synthesis system of sound PNG pictures, including：
First acquisition module, for obtaining PNG pictures and audio address date；
First parsing module for parsing the PNG pictures, obtains all data blocks of the PNG pictures, described all
Data block terminates data block including image；
Audio address add module terminates data block for adding the audio address date to described image；
Correction verification module verifies for terminating data block to the image for being with the addition of audio address date；
Image generating module, for data block will to be terminated except image after verifying successfully in addition to all data blocks and
The video data block for being with the addition of audio address date is preserved into same file successively, generates sound PNG pictures.
The beneficial effects of the present invention are：The data block of PNG pictures is obtained by parsing PNG pictures, then by audio address
Data terminate data block added to image, and the image for finally preserving other data blocks successively and having modified terminates data block, generate
New PNG pictures.The PNG pictures so generated can be identified compiling by Android or ios compilers, and new PNG schemes
The file increment of piece is very small.Audio address date therein is obtained subsequently through the PNG pictures for parsing the generation, according to the sound
The request of frequency address date set plays audio.
