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 Files\Matrox Imaging\MIL\MIL.NET

Public Class Form1
Dim MilApplication As MIL_ID = MIL.M_NULL

Dim MilImage As MIL_ID = MIL.M_NULL

Dim BufSizeX As Integer ' MIL_INT '= DEFAULT_IMAGE_SIZE_X
Dim BufSizeY As Integer 'MIL_INT '= DEFAULT_IMAGE_SIZE_Y
Dim BufSizeBand As MIL_INT '= DEFAULT_IMAGE_SIZE_BAND
Dim MilGraphicContextId As MIL_ID = MIL.M_NULL '  Graphic context identifier

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
MIL.MappAlloc(MIL.M_DEFAULT, MilApplication) '应用分配
MIL.MappControl(MIL.M_ERROR, MIL.M_THROW_EXCEPTION) '击中错误，没此句时MIL的错误不会击中，就是说没它时MIL函数有错时只会弹框而不会击中错误句子。
MIL.MsysAlloc(MIL.M_DEFAULT, "M_DEFAULT", MIL.M_DEFAULT, MIL.M_DEFAULT, MilSystem) '系统分配 双引号内区分大小写
MIL.MdispAlloc(MilSystem, MIL.M_DEFAULT, "M_DEFAULT", MIL.M_WINDOWED, MilDisplay) '显示分配

MIL.MgraAlloc(MilSystem, MilGraphicContextId)

If MIL.MsysInquire(MilSystem, MIL.M_DIGITIZER_NUM, MIL.M_NULL) > 0 Then

End If

MIL.MbufAlloc2d(MilSystem, BufSizeX, BufSizeY, 8 + MIL.M_UNSIGNED, MIL.M_IMAGE + MIL.M_DISP + MIL.M_GRAB + MIL.M_PROC, MilImage) '分配MILIMAGE图像缓冲区
MIL.MdispSelectWindow(MilDisplay, MilImage, Me.Handle) '关联显示与缓冲区

MIL.MdigGrab(MilDigitizer, MilImage) '单帧采

If MIL.M_MIL_USE_TTF_UNICODE = 1 Then
MIL.MgraFont(MilGraphicContextId, MIL.MIL_FONT_NAME(MIL.M_FONT_DEFAULT_TTF)) '关键函数，没有它时显示中文为乱码 功能：将文本字体与图形上下文关联。
MIL.MgraControl(MilGraphicContextId, MIL.M_FONT_SIZE, 24)
MIL.MgraText(MilGraphicContextId, MilImage, 200, 200, "ABC123中文")
End If

End Sub

End Class
