SkPicture drawing command alteration without regenerating

[pprabhu]

Hi , 

Was looking for ways to update/alter SkPicture drawing command without regenerating.

Sample code looks something like below :

SkCanvas *canvas = recorder.beginRecording(....)

canvas->drawRRect(...)

canvas->drawBitmapRect(bitmap,srcRect,destRect,...)

canvas->drawRect(...)

sk_sp<SkPicture> picture = recorder.finishRecordingAsPicture();

In the above code, only the values of srcRect changes quite often.

Is there any way to update this value/use the latest value in the picture object without regenerating it again.

Or  any suggestions how to handle it in a lightweight way. 

 

Thanks,

Pooja
