This article describes the use of PowerPoint tips
1, the appearance of words and lectures synchronized
To make the word appear with the narration, you can erase it in the "Custom Action" alphabetically by the right. But if a large paragraph of text, the word appears fast or too fast. This section of text can be divided into one line of text blocks, even a few words a word block, and then in order to set the animation of each word in sequence to erase the letter to the right, and in the time item set with the previous action interval of one second to three seconds, you can make text appear speed and narration consistent.
2, long time flashing the production of the font
You can also make a blinking word in, but the blinking effect in PowerPoint is just a meteor flash. To make a continuous blinking word that attracts attention, you can do this: fill in the text box with the words you want, handle the formatting and effects of the word, and make a quick or medium-speed flashing picture effect, copy the text box, determine the number of pasted text boxes based on the time you want to blink, and then set the boxes to the same location. Processing these text boxes for every second action once, set the text box to disappear after the action, so successful.
3, directory-type of jump
Use the word jump function, you can create a beautiful page directory. When you set up a jump, it is recommended that you do not set the action of the font, but to set the border of the word. This avoids the underline of the word and makes the word color unaffected by the motherboard. The specific action for the selected Word box, click the right button, select the Action Settings "", linked to the page to jump.
4, why some files are particularly large
The same is a 60 pages, 40 or so pictures of the file, one is about 4M, one is nearly 50M, this is how to go about it? After careful examination, originally is because of a BMP picture, a picture in JPG format. In the file, because the original picture larger (A3 paper size), stored in BMP format of the author, look at a file about 4M, it will be in the picture editor shrunk 16 times times (long width of the original 25%), the result of BMP file only 200K or so. And in the JPG format of the author, look at each picture file is only about 120K, directly inserted in the file, resulting in a PowerPoint file to save a JPG picture, its size becomes 4.7M. So with the size of the appropriate BMP pictures, you can make the file is not too big.
