1 Introduction

In writing this generation, I am still in trouble should be the first to write the lyrics parsing, or write lyrics generation, and then I think, in fact, it is necessary to first have lyrics file, only to parse it, of course, we can also through the existing lyrics (KRC, TRC and KSC, etc.) directly skip this step, directly parse lyrics can.

2 Making Software

Here to introduce the "Little grizzly Bear Karaoke subtitle Production Software", we can through a number of professional production software, to clarify the stir understand the production principle of lyrics. Here first:

With the use of the graph and software to create lyrics, we can know the following information:

1. Lyrics in the production of units, by "word" production

2. In the production of lyrics, the software seems to have each line of lyrics "word" is divided, it should be for the convenience of making lyrics, so pre-line lyrics into each "word", where the "word" includes: English words, numbers string, Chinese, where the space "can only" with English words, numbers string or Chinese form a " Word ", and the position of the space to be placed in the back

3. In the process of making lyrics, the music sounded, heard line lyrics in the "word", click on the "Space", here Click "Space", in fact, it should be recorded "word (a)" Occurrence time, when the next "word (B)" or change lines, then you can record "word (a)" of the duration

4. Lyrics Wrap, record line lyrics start time

5. When the lyrics are finished, the corresponding lyrics files are generated according to the lyrics format.

Note: 2nd and 3rd are the key to making lyrics, and if you can't understand them, you won't be able to make lyrics.

From the figure, graphics2d in the painting text, first draw the default color of the lyrics text, and then set the length of the clip layer width, and then paint the "highlight" lyrics text, as long as we constantly modify the width of the clip layer, we want the dynamic lyrics effect. Of course, when we are making lyrics, we just need to set the gradient increment width to the width of each "word".
