and we have a quick hack that we did to try to put one of our books on it, and it turns out that 200 dots per inch means that you can put scanned books on them that look really good.
我们正在上面写入第一本图书 它的分辨率达到了每英寸200点 这就意味着你可以把扫描过的图书放在上面,并且看起来非常舒服
dots per inch (dpi) specifies the number of pixels of the image that should be printed inside one inch (2.54cm). the higher the image's dpi, the smaller the printed image. note that your printer is unlikely to produce high quality prints if you increase this to more than 300 or 600 dpi, depending on the printer. if you would like to print the image so that it is the same size as it is displayed on the screen, set the image's dpi values to be the same as the screen's. if either dpi value is unspecified, the image will also be printed to be the same size as on the screen. not all image formats support dpi values. if the format you save in does not support them, they will not be saved.
每英寸点( dpi) 定义了图像每英寸( 2. 54厘米) 间包含的可打印像素数量。 图像的 dpi 越高, 可打印的图像就越小。 注意根据您的打印机不同, 大于 300 或 600 dpi 的图像可能会让打印机处理高质量输出时不适应 。 如果您想打印和屏幕显示大小一样的图像, 请将图像 dpi 设为和您屏幕所设的一样 。 如果两者中任一 dpi 未指定 , 图像会以和您屏幕一致的 dpi 值来打印 。 不是所有图像格式都支持 dpi 值。 如果您保存的格式不支持这些, 此值不会被保存 。
