[GDI+] 创建Images的两种方式

使用Bitmap构造完成一个新的image对象，大小为xsize,ysize

[C#]
Bitmap myImage = new Bitmap( < xsize > , < ysize > );

[VB]
Dim MyImage = new Bitmap( < xsize > , < ysize > )

下面这个方法创建一个默认颜色深度的Images对象,也可以使用像素格式化的参数构造

[C#]

Bitmap myImage = new Bitmap( < xsize > , < ysize > ,PixelFormat. < format > );

[VB]

Dim MyImage = new Bitmap( < xsize > , < ysize > ,PixelFormat. < format > )

Pixel Formats valid for the creation of a bitmap image are:

Format16bppArgb1555

Format16bppGrayScale

Format16bppRgb555

Format16bppRgb565

Format1bppIndexed

Format24bppRgb

Format32bppArgb

Format32bppPArgb

Format32bppRgb

Format48bppRgb

Format4bppIndexed

Format64bppArgb

Format64bppPArgb

Format8bppIndexed

Images 可以从磁盘装在标准格式的位图文件(JPEG, GIF, TIFF or windows Bitmap)

可以使用方法 Image.FromFile 装载指定的 Image 文件

[C#]

Bitmap bm = (Bitmap)Image.FromFile( "

 1<filename> "  );
