在上一篇"利用Assembly的GetManifestResourceStream來載入圖片資源"

但載入的圖片有時想將某些部分透明化,可以利用Bitmap的MakeTransparent來達到..

首先利用小畫家準備一張測試圖,如下所示:

部分程式碼Winform(c#)
MakeTransparent.cs

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.Reflection; namespace WindowsApplication1 { public partial class MakeTransparent : Form { public MakeTransparent() { InitializeComponent(); } private void MakeTransparent_Load(object sender, EventArgs e) { Assembly asm = Assembly.GetExecutingAssembly(); string name = asm.GetName().Name; Bitmap bmp1 = new Bitmap(asm.GetManifestResourceStream(name + ".puma.bmp"));//載入圖片資源 this.pictureBox1.Image = bmp1; Bitmap bmp2 = new Bitmap(asm.GetManifestResourceStream(name + ".puma.bmp"));//載入圖片資源 bmp2.MakeTransparent(Color.White);//將圖片白色部分透明化; this.pictureBox2.Image = bmp2; } } }

執行結果：
