在Crystal Report中插入大图像无法显示 [英] Insert big Image in Crystal Report can not display

问题描述

我在Crystal Report中遇到大图像问题如下：在第一次设计时，我可以通过将大图像插入到报告中来设计。在设计之后，我开始查看它，它也像正常一样查看大图像：第一次设计时间正常



完成设计和测试后好的，我关闭了那份报告。当我下次打开它时，即使在设计时间或查看时间内也无法显示图像。它只显示带有白色背景的图像边框。



如果我插入并设计为小尺寸，可以。但如果尺寸像这样大，那总是错误的。那么你能帮我设计一下吗？或者有什么问题和解决方案？

I have problem with big image in Crystal Report as the following: During the design time in the first time, I can design by insert the big images to the report as normal. After design, I start to view it, It also view the big image as normal as the examples: Design Time in the first time is OK

After finish design and test OK, I close that report. When I open it next time, It can not display the image even in the design time or view time. It just show the border of image with white background.
