#define搜索Python后端开发

1、

 normal shot.

 alps\mediatek\platform\mt6595\hardware\mtkcam\v1\adapter\Scenario\Shot\NormalShot\NormalShot.cpp,

 bool

 NormalShot::

 onCmd_capture()

 { 

 ...

 //加上以下code

  if(getOpenId() == 1 && bFlip){

   switch(mShotParam.mu4Transform){

    case eTransform_ROT_90:

     mShotParam.mu4Transform = eTransform_FLIP_V | eTransform_ROT_90; 

     break;

     

    case eTransform_ROT_270:

     mShotParam.mu4Transform = eTransform_FLIP_H | eTransform_ROT_90; 

     break; 

    case eTransform_ROT_180:

     mShotParam.mu4Transform = eTransform_FLIP_V; 

     break;

     

    default:

     mShotParam.mu4Transform = eTransform_FLIP_H; 

     break;

   }

  }

 //加上code，end

     // shot param 

     NSCamShot::ShotParam rShotParam(

             eImgFmt_YUY2,                    //yuv format 

             mShotParam.mi4PictureWidth,      //picutre width 

             mShotParam.mi4PictureHeight,     //picture height

             mShotParam.mu4Transform,         //picture transform 

             ePostViewFmt,                    //postview format 

             mShotParam.mi4PostviewWidth,     //postview width 

             mShotParam.mi4PostviewHeight,    //postview height 

             0,                               //postview transform

             mShotParam.mu4ZoomRatio          //zoom   

             ); 

 (2)Face beauty,

 alps\mediatek\platform\mt6595\hardware\mtkcam\v1\adapter\Scenario\Shot\FBShot\Facebeauty.cpp,

 MBOOL

 Mhal_facebeauty::

 createJpegImg(IImageBuffer const * rSrcImgBufInfo

       , NSCamShot::JpegParam const & rJpgParm

       , MUINT32 const u4Transform

       , IImageBuffer const * rJpgImgBufInfo

       , MUINT32 & u4JpegSize)

 {

 ...

 将

     pISImager->setTransform(u4Transform);

 替换为

  if(getOpenId() == 1 && bFlip){

   MUINT32 mu4Transform = 0;

   switch(u4Transform){

    case eTransform_ROT_90:

     mu4Transform = eTransform_FLIP_V | eTransform_ROT_90; 

     break;

     

    case eTransform_ROT_270:

     mu4Transform = eTransform_FLIP_H | eTransform_ROT_90; 

     break; 

    case eTransform_ROT_180:

     mu4Transform = eTransform_FLIP_V; 

     break;

     

    default:

     mu4Transform = eTransform_FLIP_H; 

     break;

   }

   pISImager->setTransform(mu4Transform);

  }else

   pISImager->setTransform(u4Transform);

 (3)zsd shot,

 alps\mediatek\platform\mt6595\hardware\mtkcam\v1\adapter\Scenario\Shot\CapBufShot\CapBufShot.cpp,

 bool

 CapBufShot::

 onCmd_capture()

 { 

 ...

 //加上以下code

  if(getOpenId() == 1 && bFlip){

   switch(mShotParam.mu4Transform){

    case eTransform_ROT_90:

     mShotParam.mu4Transform = eTransform_FLIP_V | eTransform_ROT_90; 

     break;

     

    case eTransform_ROT_270:

     mShotParam.mu4Transform = eTransform_FLIP_H | eTransform_ROT_90; 

     break; 

    case eTransform_ROT_180:

     mShotParam.mu4Transform = eTransform_FLIP_V; 

     break;

     

    default:

     mShotParam.mu4Transform = eTransform_FLIP_H; 

     break;

   }

  }

 //加上code，end

     // shot param 

     NSCamShot::ShotParam rShotParam(

             eImgFmt_YUY2,                    //yuv format 

             mShotParam.mi4PictureWidth,      //picutre width 

             mShotParam.mi4PictureHeight,     //picture height

             mShotParam.mu4Transform,         //picture transform 

             ePostViewFmt,                    //postview format 

             mShotParam.mi4PostviewWidth,     //postview width 

             mShotParam.mi4PostviewHeight,    //postview height 

             0,                               //postview transform

             mShotParam.mu4ZoomRatio          //zoom   

             );

  

 2、

 alps/mediatek/platform/mt6595/hardware/mtkcam/core/

 SingleShot.cpp

 BurstShot.cpp

 MultiShot.cpp

 pass2node.preview.cpp

 pass2node.capture.cpp

 搜索eTransform_ROT_90，

 将

     if( XX == eTransform_ROT_90 ||

             XX == eTransform_ROT_270 )

 替换为

     if( XX & eTransform_ROT_90 ||

             XX == eTransform_ROT_270)

  

 3、

 (1)alps/mediatek/platform/mt6595/hardware/mtkcam/core/iopipe/SImager/ImageTransform/ImageTransform.cpp

 MBOOL 

 ImageTransform::

 convertTransform(

     MUINT32 const u4Transform, 

     MUINT32 & u4Rotation, 

     MUINT32 & u4Flip

 )

 {

 。。。

 将

 #define TransCase( trans, rot, flip ) \

         case trans:                   \

             u4Rotation = (rot);       \

             u4Flip = (flip);          \

             break;

         TransCase(0                  , 0   , 0)

         TransCase(eTransform_FLIP_H  , 180 , 1)

         TransCase(eTransform_FLIP_V  , 0   , 1)

         TransCase(eTransform_ROT_90  , 90  , 0)

         TransCase(eTransform_ROT_180 , 180 , 0)

         TransCase(eTransform_ROT_270 , 270 , 0)

         default:

             MY_LOGE("not supported transform(0x%x)", u4Transform);

             u4Rotation = 0; 

             u4Flip = 0; 

             return MFALSE;

             break;

 #undef TransCase

 替换为

 #define TransCase( trans, rot, flip ) \

         case trans:                   \

             u4Rotation = (rot);       \

             u4Flip = (flip);          \

             break;

         TransCase(0                  , 0   , 0)

         TransCase(eTransform_FLIP_H  , 0 , 1)

         TransCase(eTransform_FLIP_V  , 180 , 1)

         TransCase(eTransform_ROT_90  , 90  , 0)

         TransCase(eTransform_ROT_180 , 180 , 0)

         TransCase(eTransform_FLIP_H|eTransform_ROT_90  , 270  , 1)

         TransCase(eTransform_FLIP_V|eTransform_ROT_90 , 90 , 1)

         TransCase(eTransform_ROT_270 , 270 , 0)

         default:

             MY_LOGE("not supported transform(0x%x)", u4Transform);

             u4Rotation = 0; 

             u4Flip = 0; 

             return MFALSE;

             break;

 #undef TransCase

 (2)alps\mediatek\platform\mt6595\hardware\mtkcam\core\iopipe\PostProc\HalPipeWrapper.cpp,

 将

 TransformMapping mTransformMapping[TRANSFORM_MAX]=

 {

     {0,                 NSImageio::NSIspio::eImgRot_0,  NSImageio::NSIspio::eImgFlip_OFF},

     {eTransform_FLIP_H, NSImageio::NSIspio::eImgRot_0,  NSImageio::NSIspio::eImgFlip_ON},

     {eTransform_FLIP_V, NSImageio::NSIspio::eImgRot_0,  NSImageio::NSIspio::eImgFlip_ON},

     {eTransform_ROT_180,NSImageio::NSIspio::eImgRot_180,NSImageio::NSIspio::eImgFlip_OFF},

     {eTransform_ROT_90, NSImageio::NSIspio::eImgRot_90, NSImageio::NSIspio::eImgFlip_OFF},

     {0,                 NSImageio::NSIspio::eImgRot_0,  NSImageio::NSIspio::eImgFlip_OFF},

     {0,                 NSImageio::NSIspio::eImgRot_0,  NSImageio::NSIspio::eImgFlip_OFF},

     {eTransform_ROT_270,NSImageio::NSIspio::eImgRot_270,NSImageio::NSIspio::eImgFlip_OFF}

 };

 替换为

 TransformMapping mTransformMapping[TRANSFORM_MAX]=

 {

     {0,                 NSImageio::NSIspio::eImgRot_0,  NSImageio::NSIspio::eImgFlip_OFF},

     {eTransform_FLIP_H, NSImageio::NSIspio::eImgRot_0,  NSImageio::NSIspio::eImgFlip_ON},

     {eTransform_FLIP_V, NSImageio::NSIspio::eImgRot_180,  NSImageio::NSIspio::eImgFlip_ON},

     {eTransform_ROT_180,NSImageio::NSIspio::eImgRot_180,NSImageio::NSIspio::eImgFlip_OFF},

     {eTransform_ROT_90, NSImageio::NSIspio::eImgRot_90, NSImageio::NSIspio::eImgFlip_OFF},

     {eTransform_FLIP_H|eTransform_ROT_90, NSImageio::NSIspio::eImgRot_270,  NSImageio::NSIspio::eImgFlip_ON},

     {eTransform_FLIP_V|eTransform_ROT_90, NSImageio::NSIspio::eImgRot_90,  NSImageio::NSIspio::eImgFlip_ON},

     {eTransform_ROT_270,NSImageio::NSIspio::eImgRot_270,NSImageio::NSIspio::eImgFlip_OFF}

 };
