reportviewer如何使矩形背景透明
[英]reportviewer How to make rectangle background transparent
问题描述
I have 3 rectangles that differ from each other in opacity. 
我有3个互不相同的矩形。 The base color is same for all of them. 所有底色都相同。 For eg: the base color could be Red and the three rectangles would have the following colors: Red, Red (opacity: 55), Red (opacity: 135). 例如：基色可以是红色，而三个矩形将具有以下颜色：红色，红色（不透明度：55），红色（不透明度：135）。
I tried setting the Background Color of the rectangle but it seems I cannot change the transparency of a rectangle. 我尝试设置矩形的Background Color ，但似乎无法更改矩形的透明度。 Is there a workaround for this? 有没有解决方法？
Thank you! 谢谢！

It turns out that this is a limitation of reportviewer. 事实证明，这是reportviewer的局限性。 Opacity values can be given to only gauges and graphs. 不透明度值只能提供给仪表和图表。 Shapes and fonts do not accept opacity values. 形状和字体不接受不透明度值。 A close workaround to this is to add the opacity value to RGB. 一个接近的解决方法是将不透明度值添加到RGB。 For example: if I want to generate a color in RGBA as (255,0,0,160) , I should add 255-160=95 to the values of G and B to get a color close to my needs. 例如：如果要在RGBA as (255,0,0,160)生成颜色RGBA as (255,0,0,160) ，则应在G和B的值上加上255-160=95 ，以获得接近我需要的颜色。 Therefore the color turns out to be (255,95,95) . 因此颜色原来是(255,95,95) 。 It is not the exact color but it is close. 它不是确切的颜色，但是很接近。 I tried this for red, blue and green colors since those are the only colors I need. 我尝试了红色，蓝色和绿色，因为这些是我唯一需要的颜色。
