Conversion of ImageSource and bitmap in WPF image control

1. Convert from bitmap to ImageSource

　　

[DllImport ("Gdi32.dll", SetLastError =true)]        Private Static extern BOOLDeleteObject (IntPtr hobject); /// <summary>        ///convert from bitmap to ImageSource/// </summary>        /// <param name= "icon" ></param>        /// <returns></returns>         Public Staticimagesource Changebitmaptoimagesource (Bitmap Bitmap) {//Bitmap Bitmap = icon. Tobitmap ();IntPtr Hbitmap =bitmap.            Gethbitmap (); ImageSource Wpfbitmap=System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap (Hbitmap, IntPtr.Zero,            Int32rect.empty, Bitmapsizeoptions.fromemptyoptions ()); if(!DeleteObject (HBITMAP)) {                Throw NewSystem.ComponentModel.Win32Exception (); }            returnWpfbitmap; }

2. Convert from bitmap to BitmapSource//<summary>

        ///convert from bitmap to BitmapSource/// </summary>        /// <param name= "BMP" ></param>        /// <returns></returns>         Public StaticBitmapSource Changebitmaptobitmapsource ( ThisBitmap BMP)            {BitmapSource Returnsource; Try{Returnsource=Imaging.createbitmapsourcefromhbitmap (BMP. Gethbitmap (), IntPtr.Zero, Int32rect.empty, BITMAPSIZEOPTIONS.F            Romemptyoptions ()); }            Catch{Returnsource=NULL; }            returnReturnsource; }

      

3. Conversion from icon to ImageSource

        /// <summary>        /// convert        from icon to ImageSource /// </summary>          Public imagesource changeicontoimagesource (icon icon)        {            = System.Windows.Interop.Imaging.CreateBitmapSourceFromHIcon (                icon). Handle,                int32rect.empty,                bitmapsizeoptions.fromemptyoptions ());            return imagesource;        }

4. Conversion from icon to ImageSource

 Internal Static classiconutilities {[DllImport ("Gdi32.dll", SetLastError =true)]            Private Static extern BOOLDeleteObject (IntPtr hobject);  Public StaticImageSource Toimagesource ( Thisicon icon) {Bitmap Bitmap=icon.                Tobitmap (); INTPTR Hbitmap=bitmap.                Gethbitmap (); ImageSource Wpfbitmap=Imaging.createbitmapsourcefromhbitmap (Hbitmap, IntPtr.Zero,                Int32rect.empty, Bitmapsizeoptions.fromemptyoptions ()); if(!DeleteObject (HBITMAP)) {                    Throw Newwin32exception (); }                returnWpfbitmap; }            //This is no additional conversion,:)             Public StaticImageSource Toimagesource ( Thisicon icon) {ImageSource ImageSource=Imaging.createbitmapsourcefromhicon (icon.                Handle, Int32rect.empty, Bitmapsizeoptions.fromemptyoptions ()); returnImageSource; }        }

Call: ImageSource Wpfbitmap = img. Toimagesource ();

5. Converting from ImageSource to Bitmap is to remove the Urisource.localpath from the ImageSource and then use the new Bitmap (FileName) method to get it. The other way I haven't found it yet

//System.Windows.Controls.Image Imguserheadfacecutedit;stringSTR1 = ((BitmapImage) (Imguserheadfacecutedit.source)). Urisource.absolutepath;//This path is not recognized by new Bitmap (STR1)stringSTR2 =( (BitmapImage) (Imguserheadfacecutedit.source)). Urisource.localpath; //Bitmap sourceimage = new Bitmap (sourceimageuri.tostring ());stringSTR3 =Strimgsourcefilename; Console.WriteLine ("Absolutepath ="+str1); Console.WriteLine ("LocalPath ="+str2); Console.WriteLine ("Srcefilename ="+ STR3);

This is the result of the operation:

Absolutepath =c:/documents%20and%20settings/zp/%e6%a1%8c%e9%9d%a2/%e6%a1%8c%e9%9d%a2%e7%a7%80/10111411409225. Jpg

LocalPath =c:\documents and settings\zp\ desktop \ Desktop Show \10111411409225.jpg

Srcefilename =c:\documents and settings\zp\ desktop \ Desktop Show \10111411409225.jpg

Who found the implementation method, leave a message ah
