This article to share with you is about PPT import GIF map can not play how to do, Xiaobian think quite practical, so share for everyone to learn, I hope you can read this article after some harvest, not much to say, follow Xiaobian to see it.

PPT import GIT diagram cannot be played

PPT imported GIT image cannot be played, because the PPT will automatically compress the image when saving, so the animation effect of GIT image will be invalid. The solution is to enter the image toolbar, check the option of compressing image when saving, and then click OK.

GIF

The GIF format is an acronym for Graphics Interchange Format, which was developed by Compu Serve in 1987 to fill gaps in cross-platform image formats. GIF is supported on a variety of platforms, including PC and Mactiontosh.

GIF is a bitmap. Bitmaps are basically made up of a number of pixels, each assigned a color, which together make up the picture. GIF uses the Lempel-Zev-Welch (LZW) compression algorithm, which supports up to 256 colors. Because of this property, GIFs are better suited for images with less color, such as cartoon shapes, company logos, and so on. If you encounter situations that require true color, then the expressive power of GIF is limited. GIFs usually come with a palette of colors that you need to use. In Web applications, the size of the image file will obviously affect the download speed, so we can optimize the palette according to the characteristics of GIF palette, reduce the number of colors used in the image (some colors that are not used in the image can be discarded), without affecting the quality of the image.

The biggest difference between the GIF format and other image formats is that it was designed entirely as a common standard and is supported by many platforms due to the popularity of the Compu Serve network. Compu Serve promotes GIFs through free distribution format manuals, but requires software that uses the GIF file format to include a description of its copyright information.

GIF Features

(1) The extension of GIF format image files is ".gif."

(2) Best performance for gray scale images.

(3) There are two versions of GIF 87a and GIF 89a.

(4) Improved LZW compression algorithm is used to process image data.

(5) The palette data is divided into general palette and local palette, with different color values.

(6) Does not support 24bit color mode, up to 256 colors stored.

The above is what to do if the PPT import GIF image cannot be played. Xiaobian believes that some knowledge points may be seen or used in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
