Delphi图片传书，可以把一段文字真正加到一幅图片中，将文字变成图片后传输，把文字隐藏在图片中，两种功能：一是文字写入图片，二是从图片读出文字。图片格式需要是BMP，比较神奇的功能。不过使用本程序需要注意：字符最多不能超过图片长*宽的1/2。举个例子来说，800*600的图片，可以容纳24000个字符，或12000个汉字。-Delphi picture-book, you can put a piece of text really added to the picture, the text becomes image after transmission, the words hidden in the picture, two functions: First, write text images, and second read out the text from the image . Picture format needs to be BMP, relatively fantastic features. However, use of this procedure to note: Images can not exceed the maximum character length* width of 1/2. For example, 800* 600 images, can accommodate 24,000 characters, or 12,000 characters.
