How to create Envelop destort mesh

[systems01h61704443]

Dear Friends,

     We are create new plugin for Illustrator CC-2018.

     Environment : MAC OS

     Language     : C++

     We need to create mesh effect for selected arts on that project.

     So we try to create mesh with using below code,but we unable to get correct result.

Sample Code :

   AIMatchingArtSpec spec;

    spec.type      = kAnyArt;

    spec.whichAttr = kArtSelected;

    spec.attr      = kArtSelected;

    error = sAIMatchingArt->GetMatchingArt( &spec, 1, &SelectedPath, &SelectedPathCNT );

    art = (*SelectedPath)[SelectedPathCNT - 1];

    if(art == NULL)

    {

        return;

    }

    sAIArt->NewArt(kMeshArt,kPlaceAboveAll,NULL,&NewArt);

    sAIMesh->InitCartesian(NewArt,4,4);

    AIMeshSegmentIterator segment= NULL;

    sAIArt->GetArtBounds(art, &artBounds);

    pointA.h=artBounds.left;

    pointA.v=artBounds.top;

    pointB.h=artBounds.right;

    pointB.v=artBounds.top;

    pointC.h=artBounds.right;

    pointC.v=artBounds.bottom;

    pointD.h=artBounds.left;

    pointD.v=artBounds.bottom;

    sAIMeshSegmentIterator->SetPoint(segment,0, &pointA); //top left corner point

    pointTMP.h=pointA.h+10;

    pointTMP.v=pointA.v;

    sAIMeshSegmentIterator->SetPoint(segment,1, &pointTMP);     //horizontal handle

    pointTMP.h=pointB.h-10;

    pointTMP.v=pointB.v;

    sAIMeshSegmentIterator->SetPoint(segment,2, &pointTMP);      //horizontal handle of next point

    sAIMeshSegmentIterator->SetPoint(segment,3, &pointB);

    sAIMeshSegmentIterator->SetPoint(segment,4, &pointC);

    sAIMeshSegmentIterator->SetPoint(segment,5, &pointD);

    sAIMeshSegmentIterator->SetPoint(segment,6, &pointB);

    sAIMeshSegmentIterator->SetPoint(segment,7, &pointC);

    sAIMeshSegmentIterator->NextOnPatch(segment,kAIMeshCounterClockwise); //top right corner

    sAIEnvelopeSuite->MakeEnvelope(&art,1,NewArt,nil,&envelop);

    sAIEnvelopeSuite->SetEnvelopeObject(envelop,NewArt);

Result Snap:

          All the anchor point are placed on origin point.Ref above snap

Excepted Result Snap:

please check above code. I think i made some mistake or missing some process on above code.

Ref above exception result on snap.

If any one have idea about this process kindly help to me.

I will wait for your reply.

With Regards,
