mapx+vb图元基本操作

本文主要是介绍mapx+vb图元基本操作，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

'1创建图层
Dim lyr As Layer
Set lyr = Map1.Layers.CreateLayer("Car")
Set Map1.Layers.AnimationLayer = lyr                '定义为动态图层

'2新建图元
Dim newobj As New MapXLib.Feature 'stand-alone object
Dim obj As MapXLib.Feature  'to hold feature added to layer
Dim NewStyle     As New MapXLib.Style
Dim str As String

newobj.Attach Map1

With NewStyle
        .SymbolType = miSymbolTypeBitmap
        .SymbolBitmapSize = 24
        .SymbolBitmapTransparent = True
        .SymbolBitmapName = "CAR1-32.BMP"
End With
newobj.Style = NewStyle                           '设置图元样式

newobj.Type = miFeatureTypeSymbol                 '设置图元类型

newobj.Point.Set Text1.Text, Text2.Text           '设置图元位置

Set obj = Map1.Layers(1).AddFeature(newobj)

obj.Update

'3移动图元
Dim lyr As MapXLib.Layer
Set lyr = Map1.Layers("Car")

Dim ftr As New MapXLib.Feature
Set ftr = lyr.AllFeatures.Item(1)

'ftr.Point.Set 116, 40    '重置图元位置
ftr.Offset 1#, 1#        '移动图元
ftr.Update

'4删除图元
Dim lyr As Layer
Set lyr = Map1.Layers("Car")
lyr.DeleteFeature (lyr.AllFeatures.Item(1))
