Question

我能够为WEC7-x86成功构建qtwebkit-5.4.2。但是，在尝试使用Webkit示例浏览器（qtwebkit-examples \ examples \ webkitwidgets \ browser）时，它无法加载以文件为源（* .svg）的svg图像。另外，当我尝试内联插入相同的svg时，它加载正常。我还尝试了qtwebkit-5.4.2的Desktop（x86）构建，它能够完美地加载附加的html。

下面是使用的html，以及台式机和WEC7-x86设备上的呈现的页面截图。

<html>
<head>

        body, button {

            font-size: 40px;
            font-family: Tahoma, Verdana, Arial, sans-serif;
        }

        .backimage_svg {
            width: 155px;
            height: 155px;
            background-image: url("polygon.svg");
            background-color: rgb(255,255,204);
        }

        .backimage_png {
            width: 155px;
            height: 155px;
            background-image: url("polygon.png");

        </svg>
    </button>
    <button class="backimage_png">10</button>
</body>
</html>

我尝试搜索是否存在已知问题，但没有找到任何东西（某些人遇到了高度不正确的svg等问题）。

以下是上面html中称为“ polygon.svg”的svg文件：

<svg width="155" height="155" xmlns ="http://www.w3.org/2000/svg">
  <polygon fill-rule="evenodd" clip-rule="evenodd" fill="#0CB9C7" points="128.25,26 147.19,96.69 95.44,148.44 24.75,129.5 5.81,58.81 57.56,7.06 "/>
</svg>

以下是WEC7和桌面上的渲染屏幕截图：

WEC7渲染屏幕截图

从屏幕截图中可以看到，WEC7浏览器无法渲染以本地文件源（2、4、5、7、8）形式显示的svg图像。

请有人提出解决方案或可能的调试方法。

谢谢。

更新：我尝试了qtsvg示例（qtsvg \ examples \ svg \ svgviewer），它能够从文件源加载svg图像。如果有人可以将我精确地指向在通过qtwebkit浏览器进行渲染时正在处理此部分的代码，那将非常有帮助。然后，我将尝试比较WEC7和桌面代码。谢谢。

更新：使用以下配置，也可以在Desktop-x86构建中重现相同的内容（如果使用qt-5.4.2 Windows Installer /预构建的二进制文件，则可以正常工作）：
