ANE，iOS版和BitmapData

有位圖數據傳遞到iOS和返回modfified副本的任何實例。我想一個位圖轉換成JPEG - 類似於此示例在Windows http://blog.magicalhobo.com/2011/09/12/air-3-native-extension-imagepro cessor /但每一次崩潰。ANE，iOS版和BitmapData

我很確定我正在做一些基本的錯誤，但不是一個iOS/Objective C程序員我真的只是嘗試魔術咒語，我找不到任何好的例子。任何幫助表示讚賞？

P.S.下面是我的嘗試：

FREObject encodeJPEG(FREContext ctx, void* funcData, uint32_t argc, FREObject argv[]) 
{ 
    FREObject  objectBitmapData = argv[0]; 
    FREBitmapData bitmapData; 

    FREAcquireBitmapData(objectBitmapData, &bitmapData); 

    int width  = bitmapData.width; 
    int height  = bitmapData.height; 
    int stride  = bitmapData.lineStride32 * 4; 
    uint32_t* input = bitmapData.bits32; 

    FREReleaseBitmapData(objectBitmapData); 


    UIImage *myImage = [UIImage imageWithData:input]; 
    NSData *jpgData = UIImageJPEGRepresentation(myImage, 0.9);  

    FREObject objectByteArray = argv[1]; 
    FREByteArray byteArray; 

    FREObject length; 

    FRENewObjectFromUint32(jpgData.length, &length); 

    FRESetObjectProperty(objectByteArray, (const uint8_t*) "length", length, NULL); 

    FREAcquireByteArray(objectByteArray, &byteArray); 

    memcpy(byteArray.bytes, jpgData.bytes, jpgData.length); 
    FREReleaseByteArray(objectByteArray); 

    return NULL;

}

作爲一種替代方法，您可以在Ac內部將位圖轉換爲JPEG格式tionScript，使用https://github.com/mikechambers/as3corelib – 2011-12-15 19:44:27

其彎曲移動，並在動作太慢 - 覺得我有這樣的破解會後不久，一次測試。 – user1100434 2011-12-16 00:54:05

這有點兒工作，除了紅色爲jpeg藍色和不知道我釋放一切就OK了。

即將明天的戰鬥。

結局版本 - 似乎確定工作 - 編碼確定，我想以後自己確定清理。

交易所的紅色和藍色像素

位置你的iOS獲得的格式是：0xAARRGGBB
和一個預計將顯示在AIR應用程序是：0xAABBGGRR
