Localreport渲染EMF图像dpi设置 [英] Localreport render EMF image dpi settings

问题描述

嗨大家好，

我正在开展一个项目，其中应该改变 localreport （VS2005）。
我将报告呈现为EMF输出格式，然后将流保存为tiff图像。
如果报告长度为多页，我会得到多个流和多个tiff图像。到目前为止一切顺利。但分辨率太低了。保存的报告中的文字tiff有点模糊。

==> 如何在渲染的EMF中获得更高的分辨率？


我试图在DeviceInfo中指定dpi ，但无论指定什么，它总是96dpi。

如果我将outputformat更改为TIFF，那么DpiX和DpiY设置可以正常工作......但是我遇到了另一个问题。在TIFF输出格式的情况下，我只返回1个流，即使我的报告长度超过1页。这导致tiff文件只包含第一页...

感谢您的帮助！
Lieven。

Hi folks,

I am working on a project in which a localreport (VS2005) should be tiffed.
I render the report to an EMF outputformat and then save the streams as a tiff image.
If the report is multiple pages long, I get multiple streams and multiple tiff images. So far so good.
The resolution however is too low. Text in the saved report tiff is kinda blurry.

==> How can I get a higher resolution in the rendered EMF?


I have tried to specify the dpi in the DeviceInfo, but whatever specified, it is always 96dpi.

If I change the outputformat to TIFF, then the DpiX and DpiY settings do work... but then I encounter another problem. In the TIFF outputformat case, I get only 1 stream back, even if my report is more than 1 page long. This results a tiff file containing only the first page...

Thanks for your help!
Lieven.

推荐答案

我最初认为你应该将StartPage设置为零，但后来我抓住了你的代码并尝试了它，我认为你和我之间的区别是我将OutputFormat设置为TIFF而不是EMF，因为这是您最终想要的结果。 
多页生成就好了。

I initially thought you should set the StartPage settings to zero, but then I grabbed your code and tried it and I think the difference between yours and mine is I set the OutputFormat to TIFF instead of EMF since that is what you want to end up with anyway.  It generates just fine with multiple pages.
