推荐答案

假设：您尝试使用相同的打印机以相同的比例打印相同的图像（没有Crystal Reports）并打印得很好。



我对Crystal Reports问题的个人解决方案是停止使用它们并使用.NET 2D绘图类。经过一段时间习惯布局逻辑后，我得到了我想要的东西。这包括图形，文本布局，阴影背景等。此外，由于数据按您编写的顺序排列，您可以将文本分层到图形*上。当然，分页是可用的。



相同的绘图工具可以用来装饰应用程序窗口 - 这是一个额外的好处，可以让你的工作更具触感。 />














*图形可以是一个表格，你可以在（扫描）表格的图像上有填写框并打印所见即所得。

Assumption: you tried printing the same image with the same printer at the same scale (without Crystal Reports) and it printed well.

My personal solution to Crystal Reports problems was to stop using them and use the .NET 2D drawing classes. After a period of getting used to the layout logic I get exactly what I want. This includes graphics, text layouts, shaded backgrounds, etc. Furthermore, since data is laid out in the order you write them, you can layer text onto graphics*. Paging is, of course, available.

The same drawing tools can be used to decorate an application window - an added bonus to give your work that extra touch.







*graphic could be a form and you can have fill-in boxes on an image of a (scanned) form and print it WYSIWYG.

可以使用水晶报告中的保留原始图像颜色深度来完成。



我使用的是与Visual Studio 2015捆绑在一起的Crystal Reports。解决方案如下 -



1-右键点击Crystal Report。

2-点击上下文菜单中的报告。

3-从子上下文菜单中单击报告选项。

4-现在从显示的对话框中选中保留原始图像颜色深度

5-点击确定。

6-运行你的项目。



就是这样......

It can be done by using 'Retain Original Image Color Depth' in crystal reports.

I am using Crystal Reports bundled with Visual Studio 2015. Solution is as below-

1- Right Click on Crystal Report.
2- Click 'Report' from context menu.
3- Click 'Report Options' from sub context menu.
4- Now from the displayed dialog box check(on) the Retain Original Image Color Depth
5- Click OK.
6- Run your project.

That's it...
