mil10(MATROX IMAGING LIBRARY 10)图像框中显示中文
默认情况下，mil10(MATROX IMAGING LIBRARY 10)图像框中显示中文时，它会显示乱码，这是由于用户未指定字体所致，以前开发时需要用到此功能，并且以为它不能显示中文。原来是可以的。
系统配置：MIL10 64位（以前的MIL9版本并未测试）WIN10 64,VISUAL STUDIO 2019, MATROX SOLIOS(SOL2MECLF) CAMERALINK采集卡 SONY XCL-C500相机。
代码如下(vb.net)：

'MIL 图像框显示中文
Imports Matrox.MatroxImagingLibrary '要先引用它Matrox.MatroxImagingLibrary.dll  它位于C:Program FilesMatrox ImagingMILMIL.NET

Public Class Form1
Dim MilApplication As MIL_ID = MIL.M_NULL
