在 Delphi 开发中，打印画布上填充方式为非 bsSolid 的图形时，打印出来后会变成黑色的背景，显然这不是我们要的效果。



为什么会出现左图这种不正常的情况呢？



打印非 bssolid 笔刷填充方式的主要问题是 GDI 采用单色小 8* 8 位图来实现这些填充效果，在计算机屏幕排列可以得到你想要的效果，但是在高分辨率的打印机上， 由于模式的排列太靠近，以至于看起来合并到一块了，从而会产生这样的打印问题。-At Delphi development, print on canvas filled bsSolid non-graphics mode, the print out would become a black background, it is clear this is not the effect we want. Why is there left of this abnormal situation? Print non-bssolid brush-filled forms of the main problems are the use of GDI small monochrome 8* 8 map to achieve the effect of these filled in with the computer screen can be the effect you want, but at high-resolution printers, because of model too close to the arrangement that appears to merge into one, and thus will have such a problem printing.
