黄玉sigplusnet在报告中透明背景 [英] Topaz sigplusnet in a report with transparent background

问题描述

我在XRPictureBox控件中的DevExpress winforms报告中使用SigPlusNET。它是一个DevExpress控件真的不重要，但这就是我正在使用的。



完全正常。但是，我在报告中有一条水平线，我希望通过签名框显示，以便看起来像是在线上签名的人，这样如果有j或g或其他此类字母在签名中，它不必在线上。如果我把图片框放在线上，那就好了。但如果我重叠它们，盒子就会隐藏线条。我尝试将sp.BackColor设置为透明，但不接受。有没有人知道这是否可以使用SigPlusNET对象？



提前致谢，

我尝试过：

I'm using SigPlusNET in a DevExpress winforms report in an XRPictureBox control. it's really not important that it's a DevExpress control but that's what I'm using.

It works completely fine. However, I've got a horizontal line on the report that I would like to show through the signature box so that it looks like the person signed on a line, so that if there's a "j" or "g" or other such letter in a signature it doesn't have to be above the line. If I position the picture box above the line it's all good. But if I overlap them, the box hides the line. I tried setting the sp.BackColor to transparent but it won't accept that. Does anyone know if this is possible with the SigPlusNET object?

Thanks in advance,

What I have tried:

Here's my code:

<pre lang="vb">Dim driverSignatureString As String = Me.GetCurrentColumnValue("DriverSignature").ToString

Dim sp As SigPlusNET = New SigPlusNET
sp.ClearTablet()
sp.SetSigCompressionMode(1)
sp.SetJustifyMode(5) '5 is justify and zoom signature (center of control)
sp.SetJustifyX(12) 'this is really just padding
sp.SetJustifyY(12)
sp.SetImageXSize(300)
sp.SetImageYSize(45)
sp.SetImagePenWidth(5)
sp.SetDisplayWindowRes(True)
sp.SetSigString(driverSignatureString)

Me.xrPicDriverSignature.Image = sp.GetSigImage()

推荐答案

该行的z-order是什么？



通常这只是w中顺序的问题将控件添加到可视树中，该可视树确定哪个控件（部件）覆盖另一个（如果有的话）;这就是人们所看到的。

What's the "z-order" of the line?

Usually it's just a question of the order in which controls are added to the "visual tree" that determines which control (part) overlays another, if any; and that is what one sees.
