Why Isn't My GIF Animated in LabVIEW?



Primary Software: LabVIEW Development Systems>>LabVIEW Base Development System
Primary Software Version: 2016
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem:
I have an animated GIF that I've added to my front panel or block diagram. However, only the first frame of the animated GIF displays. Why isn't the GIF animated in LabVIEW?

Solution:
LabVIEW does allow you to place some animated GIFs on the front panel and the block diagram. However, because of the way GIFs are encoded, not every GIF is supported in LabVIEW. Here are a couple of ideas to animate your image in LabVIEW:
  • If you have software which allows you to create animated GIFs, try breaking the animation into its separate images and re-compiling them into a GIF. This will recreate the gif into a format that LabVIEW supports.
  • Break the animation into its separate images and use a picture ring to animate them.
Attached are a two examples of GIFs which will work in LabVIEW that were found on Google.

Technical Explanation:

Because of the way the GIF specification is defined, there are multiple methods to do animation of GIFs. LabVIEW does not support every method. One example of a case that LabVIEW does not necessarily support is the use of extension blocks.

Extension blocks extend the GIF specification to include modifications that the decoder does not fully understand. Not every decoder is designed to handle every case of an extension block. For example, a web browser designed to handle specific extension blocks may be able to load GIF types that most other decoders cannot . The effect of this is that some animated GIFs will work in LabVIEW and others will not.
