随着学术交流的广泛开展,应用文字、图表的幻灯片日益增多。在幻灯片的制作中,对文字图表原稿的字体大小、笔画宽度以及缩放比例缺乏科学计算,往往因字迹模糊不清,未能达到预期的放映效果,或因字体太大而降低有效画面的利用率。根据几年来的工作实践,初步摸索出一个既能提高画面的有效利用率,又能保证放映影像清晰度的一种计算原稿大小和字体笔画宽度的方法。现将该法简报如下。
With the extensive academic exchange, the application of text, charts slide more and more. In the production of slides, the lack of scientific calculation of font size, strokes width and zoom ratio of the text of the original manuscript often fails to achieve the expected screening effect due to the illegible writing or the use of effective images due to too large font sizes rate. According to the work practice of the past few years, a method of calculating the width of the original and the size of the original script, which is not only able to improve the effective use of the screen but also ensure the clarity of the projected image, is initially explored. The law is now briefed as follows.
