圖像插值C＃2010

我使用這個圖片：圖像插值C＃2010

我想用出的顏色的混合超級它的大小。有沒有辦法通過C＃中的顏色混合來放大它？我在網上查了一下，但所有的方法都沒有成功。

我應該給我怎麼回事，通過把圖像在屏幕上。

我正在關閉，但需要多一點幫助，我準備好通過SpriteBatch.Begin Methods和他們做什麼，但還是很失落我喜歡一些幫助，這個問題。

如果我使用矢量，它會超小，它將無法被看到。我需要增加它的尺寸，使它失去其全部顏色並保持它的顏色。 –

請理解：http://i.imgur.com/Cgx9AYz.png我想有一個矩形具有正確的尺寸，並保持它好，因爲當它是小 –

你的意思是'VECTOR'，可容納無數的信息或將圖像定位在屏幕上的'vector2'。 –

通過添加spriteBatch.Begin(SpriteSortMode.FrontToBack, BlendState.AlphaBlend, SamplerState.PointClamp, DepthStencilState.Default, RasterizerState.CullCounterClockwise);我能解決這個問題。現在一切都按我需要的方式工作。

如果我正確地解釋你的問題，你想放大的圖像沒有它越來越模糊，所以不是任何「聰明」的調整，你只是想增加規模與「近鄰」的方法。你可以這樣說：

using System.Drawing; 
using System.Drawing.Drawing2D; 

private Bitmap ResizeBitmap(Bitmap b, int nWidth, int nHeight) 
{ 
    Bitmap result = new Bitmap(nWidth, nHeight); 
    using (Graphics g = Graphics.FromImage((Image)result)) 
    { 
     g.InterpolationMode = InterpolationMode.NearestNeighbor; 
     g.DrawImage(b, 0, 0, nWidth, nHeight); 
    } 
    return result; 
}

效果最好確切的倍數：如果你有一個50x70的圖像也調整到 100x140/150x210等

我從這裏的解決方案： Resize a bitmap like MS Paint - no antialiasing

位圖不在構造函數中，你知道添加到這個構造函數的類型嗎？（例如：'使用Microsoft.Xna.Framework.Graphics;'）我也不知道我是否應該把它加載（'圖像'），它的大小和放在屏幕上（'TitleScreen'）還是它被繪製（'Game1'）。 –

您可以使用快捷鍵SPACE +。獲取自動導入建議。你需要這兩個：使用System.Drawing; using System.Drawing.Drawing2D; – Traubenfuchs

此時它聲明名稱空間「System」中不存在類型或名稱空間名稱「Drawing」。我需要設置繪圖嗎？ –
