如何讓圖像旋轉看起來乾淨？ Android GL ES

Question

我正在讀這本名爲Android的初級遊戲。

在它在SpriteBatcher類下面的方法的書......

public void drawSprite(float x, float y, float width, float height, float angle, TextureRegion region) { 
    float halfWidth = width/2; 
    float halfHeight = height/2; 

    float rad = angle * Vector2.TO_RADIANS; 
    float cos = FloatMath.cos(rad); 
    float sin = FloatMath.sin(rad); 

    float x1 = -halfWidth * cos - (-halfHeight) * sin; 
    float y1 = -halfWidth * sin + (-halfHeight) * cos; 
    float x2 = halfWidth * cos - (-halfHeight) * sin; 
    float y2 = halfWidth * sin + (-halfHeight) * cos; 
    float x3 = halfWidth * cos - halfHeight * sin; 
    float y3 = halfWidth * sin + halfHeight * cos; 
    float x4 = -halfWidth * cos - halfHeight * sin; 
    float y4 = -halfWidth * sin + halfHeight * cos; 

    x1 += x; 
    y1 += y; 
    x2 += x; 
    y2 += y; 
    x3 += x; 
    y3 += y; 
    x4 += x; 
    y4 += y; 

    verticesBuffer[bufferIndex++] = x1; 
    verticesBuffer[bufferIndex++] = y1; 
    verticesBuffer[bufferIndex++] = region.u1; 
    verticesBuffer[bufferIndex++] = region.v2; 

    verticesBuffer[bufferIndex++] = x2; 
    verticesBuffer[bufferIndex++] = y2; 
    verticesBuffer[bufferIndex++] = region.u2; 
    verticesBuffer[bufferIndex++] = region.v2; 

    verticesBuffer[bufferIndex++] = x3; 
    verticesBuffer[bufferIndex++] = y3; 
    verticesBuffer[bufferIndex++] = region.u2; 
    verticesBuffer[bufferIndex++] = region.v1; 

    verticesBuffer[bufferIndex++] = x4; 
    verticesBuffer[bufferIndex++] = y4; 
    verticesBuffer[bufferIndex++] = region.u1; 
    verticesBuffer[bufferIndex++] = region.v1; 

    numSprites++; 
} 

我的問題是你如何順利下方轉動像一個圖像，使圖像不要」中的臺詞看起來像素化？

我確實擁有合適大小和DPI的圖像，並且在旋轉之前看起來很棒，但是當它旋轉時，線條的邊緣看起來並不那麼棒。

你可以嘗試使用線性採樣，而不是NEAREST，雖然這是我很難沒有看到問題的照片，或者看到你的紋理創建代碼猜測更多。
