Performance issue when lottie has png
blend_image_xform executing time is too long.
Lottie resource: performance.zip
Test device: Huawei GR5 mini
Benchmarked on this lottie resource, it took about ~70ms each time for blend_image_xform to be done. Airbnb's lottie-android is a lot faster.
@sonphan12 , yes the image implementation is not optimal. it was using Qt version before but was removed because of license issue. So i just added a simple version for feature completeness. I need to find out if there is some optimal implementation which is MIT license then we can make use of that. If you have some idea you can contribute as well :)
@smohantty Thanks for your response.
Can you please tell me why do you need to use Qt before? I can't figure out why, what is it for?
As a library user with very little experiences in C++, I have no idea how to improve this :( But thank to your response, I'm gonna revert to the old pieces of code that use Qt to improve my app's performance of png lottie.
I'm gonna leave this issue open for now since it's still a known-but-not-solved-yet problem.
@smohantty I tried to revert to before commit removing Qt's code. It is still too slow.
