i have a two question.
first i want copy image in pixel by pixel
Bitmap mSnowflake = BitmapFactory.decodeResource(mContext.getResources
(), R.drawable.snowflake);
//mSnowflake is black background in white snowflake
Bitmap mChangedBitmap = Bitmap.createBitmap(mSnowflake.getWidth
(),mSnowflake.getHeight(),Config.ARGB_8888);
copyImage(mSnowflake,mChangedBitmap);
public void copyImage(Bitmap bmSrc,Bitmap bmDest){
for(int x = 0x00; x < bmSrc.getWidth(); x++){
for(int y = 0x00; y < bmSrc.getHeight(); y++){
bmDest.setPixel(x, y, bmSrc.getPixel(x, y));
}
}
}
i want SrcImage and DestImage very same but DestImage are not same
very slime snowflake
why loss color pixel in destImage i dont Know....
second i want change image color
Bitmap mSnowflake = BitmapFactory.decodeResource(mContext.getResources
(), R.drawable.snowflake);
//mSnowflake is black background in white snowflake
i want show red snowflake but <<check error
public void setAlpha(Bitmap bmSrc,int nOpacity){
for(int x = 0x00; x < bmSrc.getWidth(); x++){
for(int y = 0x00; y < bmSrc.getHeight(); y++){
int nColor = bmSrc.getPixel(x,y);
if(nColor != 0x00){
bmSrc.setPixel(x, y, Color.RED);<< error
}
}
}
}
