Problems solved by technology

Therefore, in the process of converting a GIF file into a SWF file, if you directly copy the content of each frame, the display time of different frames of the GIF file will become the same in the SWF file, so there will be a difference between the converted SWF file and the GIF file. The file display effect is inconsistent, the playback is not consistent, and the animation image display effect is not good

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] The present invention is described by taking the conversion of a GIF file into a SWF file as an example. Both the GIF file animation and the SWF file animation are formed by playing multiple frames with different content continuously, and both of them can define the display time of each frame of image. The difference is that the GIF file can independently set the display time of each frame of the image, that is, the time interval between the current frame and the next frame can be independently set, so the GIF file can set the time interval between frames to be different , and the SWF file controls the playback speed by setting the frame rate, so the display time of each frame is fixed, that is to say, the time interval between frames is the same. So when converting a GIF file into a SWF file, there will be a problem of conver...

Abstract

The method comprises: calculating the common divisor of display times of all frames for the files to be converted; setting the common divisor as the display time of each frame of converted file; to correspond to the frames of the file to be converted, creates the frame of converted file; the numbers of the created frames is the quotient of the display time of frame of the file to be converted by the common divisor; the contents of the frames of the file to be converted are respectively copied to the each frame of converted file. The invention can converts the file to be converted that has non-fixed time interval between frames into the converted file that has fixed time interval between frames.

Description

technical field [0001] The invention relates to computer animation production technology, in particular to a conversion method between different types of files. Background technique [0002] In early computer animation production, Graphics Interchange Format (GIF, Graphics InterchangeFormat) files were the main form of implementation. Today, with the rapid development of the Internet, Flash technology has gradually replaced GIF and has become the most powerful tool for making multimedia animations on web pages. Flash is a multimedia animation production software launched by MACROMEDIE Company of the United States. It is an interactive animation design tool, which can easily integrate music, sound effects, and animation to produce high-quality animation effects. [0003] Flash technology can be used to produce an animation with a suffix of SWF (Shockwave Format). The animation image in this format can express rich multimedia forms with a relatively small volume. In terms o...
