Deflater in PngEncoder is never released

Hello

I am using Kapng-Android to output Apng with an Android application.
Thank you very much.

Regarding Issue of the main subject, I received the following warning called LeakedClosableViolation in the process of adding Frame of Apng. Checking the warning explains that the Deflater instance in PngEncoder is not released. Is there anything you know about this?

I don't know if this is directly related, but OutBytes in PngEncoder was not closed. This issue has not been warned, but I feel like I'm likely to receive a warning from LeakedClosableViolation as well. Therefore, if you haven't closed it unintentionally, I would like you to add a modification to close it.

Thank you for your response.

@oupson @carkchard @jisungbin @mogamusa31 It will be really helpful if you guys can look into this ASAP!

Invalid apng when using ExperimentalApngEncoder

Seems to be related with the non transparency of the source image or to the way the image is compressed / interlaced

Produce an invalid apng at the end

I want to release image and pngBytes in PngEncoder after outputting Apng.

Hello

I am using Kapng-Android to output Apng with an Android application.
Thank you very much.

Regarding the main subject, I want to release image and pngBytes in PngEncoder after outputting Apng because these variable remains after outputting Apng As you can see in the image below. would you offer me how to release these variable? If there is no way, I want to add a function for release. Specifically, I'd like you to add the following functions. Maybe I would be happy if the function was prepared as a static function.

fun release() {
    image?.recycle()
    image = null
    pngBytes = null
}

speed in ApngAnimator is never used

I wanted to try and set the duration of each animation. The setSpeed() method looked promising, but on inspection the speed is never used. Is this on purpose? Is there another way to set each frame duration?

Add listener to know when animation loops

Would it be possible to add a listener so that we can be notified of when the animation has hit the last frame and is starting a new loop?
