问题描述

WPF:我在ScrollViewer中有一个Image控件，并将TIFF文件设置为其源.在某些高度值(介于图像实际高度的40％到60％的范围内)中，以黑色覆盖层显示的图像.这需要以某种方式解决.仅在某些高度范围内会发生此问题，当更改为其他高度时，它会正常工作.

WPF:  I've a Image control inside a ScrollViewer and TIFF file set as its source. Image displayed with black overlay for some height values (in range of 40% to 60% of image's actual height).  This need to be resolved somehow. Only for some height range this problem occurs and when changed to other height it works normal.

<ScrollViewer
 
Grid
.
Column
=
"2"
 
Margin
=
"5"
 
HorizontalScrollBarVisibility
=
"Visible"
 
VerticalScrollBarVisibility
=
"Visible"
>


    
<Image
 
Source
=
"doc.tif"
 
Grid
.
Row
=
"0"
 
Height
=
"3510"
 
Stretch
=
"Uniform"
 
StretchDirection
=
"Both"
/>



</ScrollViewer>

您好，Anwarcode，

Hi Anwarcode,

我对此进行了测试，但是无法重现此问题.您能否提供一个简化且易于运行的示例来演示您遇到的问题?

I have made a test for that, but I cannot reproduce this issue. Could you please provide a simplified and ready-to-run example to demonstrate the issue you are encountering?

这是我的测试代码，如下所示:
XAML

This is my test code as follows:
XAML

< ; 窗口 : ='"WpfApplication1.ScrollViewImage"

=" http://schemas .microsoft.com/winfx/2006/xaml/presentation;

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

: x =" http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

=" ScrollViewImage" 高度 ="300" 宽度 ="300">

    Title="ScrollViewImage" Height="300" Width="300">

< >

< 边距 =可见" VerticalScrollBarVisibility =可见"

< 来源 ="3510-1" =" Uniform" StretchDirection

            <Image Source="htl.tif" Height="3510" Stretch="Uniform" StretchDirection="Both"/>

</ ScrollViewer </ 网格 </ >

图像显示完美，也许图像之间有些区别.

The image displays perfect, maybe there’s something difference between the images.
