**Summary:** The API for Animated PNG (Animated Portable Network Graphics) image file format<br/>            creation is a dynamic tool for developers seeking to generate captivating<br/>            animated images. With customizable options such as frame duration and the<br/>            number of times to loop, this API allows for fine-tuning animated content<br/>            according to specific needs. Whether creating engaging web graphics or<br/>            interactive visuals, you can leverage this API to seamlessly incorporate<br/>            APNG images with precise control over animation parameters.

## **Examples**
### The following example shows how to export to APNG file format. {#example_208}
``` python

import aspose.pycore as aspycore
from aspose.imaging import *
from aspose.imaging.imageoptions import *

with Image.load("Animation1.webp") as image:
	# Export to APNG animation with unlimited animation cycles as default
	image.save("Animation1.webp.png", ApngOptions())
	# Setting up animation cycles
	obj_init = ApngOptions()
	# 5 cycles
	obj_init.num_plays = 5
	image.save("Animation2.webp.png", obj_init)


```

``` python

from aspose.imaging import Image
from aspose.imaging.imageoptions import ApngOptions

with Image.load("img4.tif") as image:
	# Setting up the default frame duration
	obj_init = ApngOptions()
	# 500 ms
	obj_init.default_frame_time = 500
	image.save("img4.tif.500ms.png", obj_init)
	obj_init2 = ApngOptions()
	# 250 ms
	obj_init2.default_frame_time = 250
