Android圖像處理庫

Question

我正在研究小型android應用程序，並且我想對圖像，即素描，單色，棕褐色，木炭，油畫，否定，翻轉，翻牌，浮雕等效果在圖像上做一個效果，色調，飽和度，亮度，對比度，圖像清晰度。 有沒有這樣的工具的任何Android庫。 我真的很感激任何幫助。

Answer 1

試試這個庫

Answer 2

基本圖像效果可以通過非標準Android的工具來實現。考慮android.graphics包（它們與本地圖像格式和位圖工作）

使用下面的代碼來對比增加了位：值的範圍從1到100

public static Bitmap AdjustContrast(Bitmap original, float Value){ 
     Value          = (100.0f + Value)/100.0f; 
     Value *= Value; 
     Bitmap newBitmap       = Bitmap.createBitmap(original.getWidth(), original.getHeight(),original.getConfig()); 
     int[] argb         = new int[original.getWidth() * original.getHeight()]; 
     original.getPixels(argb, 0, original.getWidth(), 0, 0, original.getWidth(), original.getHeight()); 
     for (int i = argb.length - 1; i >= 0; --i) { 
     int alpha         = argb[i] >> 24; 
     int red          = (argb[i] >> 16) & 0xFF; 
     int green         = (argb[i] >> 8) & 0xFF; 
     int blue         = argb[i] & 0xFF;   
     float Red         = red/255.0f; 
     float Green         = green/255.0f; 
     float Blue         = blue/255.0f; 
     Red           = (((Red - 0.5f) * Value) + 0.5f) * 255.0f; 
     Green          = (((Green - 0.5f) * Value) + 0.5f) * 255.0f; 
     Blue          = (((Blue - 0.5f) * Value) + 0.5f) * 255.0f; 
     int iR          = (int)Red; 
     iR           = iR > 255 ? 255 : iR; 
     iR           = iR < 0 ? 0 : iR; 
     int iG          = (int)Green; 
     iG           = iG > 255 ? 255 : iG; 
     iG           = iG < 0 ? 0 : iG; 
     int iB          = (int)Blue; 
     iB           = iB > 255 ? 255 : iB; 
     iB           = iB < 0 ? 0 : iB;     
     int composite        = (alpha << 24) | (iR << 16) | (iG << 8) | iB; 
     argb[i]          = composite; 
     } 
     newBitmap.setPixels(argb, 0, original.getWidth(), 0, 0, original.getWidth(), original.getHeight()); 
     Store.lastBitmap       = newBitmap; 
     return newBitmap; 
    } 

使用此亮度效果：值應介於1到100之間

public static Bitmap makeBrightnessBitmap(Bitmap original, int brightness){ 
     Bitmap newBitmap       = Bitmap.createBitmap(original.getWidth(), original.getHeight(),original.getConfig()); 
     int[] argb         = new int[original.getWidth() * original.getHeight()]; 
     original.getPixels(argb, 0, original.getWidth(), 0, 0, original.getWidth(), original.getHeight()); 
     for (int i = argb.length - 1; i >= 0; --i) { 
      int alpha        = argb[i] >> 24; 
      int red         = (argb[i] >> 16) & 0xFF; 
      int green        = (argb[i] >> 8) & 0xFF; 
      int blue        = argb[i] & 0xFF;      
      int red2        = red + brightness; 
      if (red2>0xFF) red2      = 0xFF; 
      if (red2<0) red2      = 0; 
      int green2        = green + brightness; 
      if (green2>0xFF) green2     = 0xFF; 
      if (green2<0) green2     = 0; 
      int blue2        = blue + brightness; 
      if (blue2>0xFF) blue2     = 0xFF; 
      if (blue2<0) blue2      = 0;     
      int composite       = (alpha << 24) | (red2 << 16) | (green2 << 8) | blue2; 
      argb[i]         = composite; 
     } 
     newBitmap.setPixels(argb, 0, original.getWidth(), 0, 0, original.getWidth(), original.getHeight()); 
     Store.lastBitmap       = newBitmap; 
     return newBitmap; 
    }
