GIF Zip Import support

I think it won't be a big thing to implement in the ZIP import function also the support of the GIF format. This would open new ways how to process files. It can also be another picture format, which can be animated.

What do you think?

GIF format is not efficient as PNG files, also make the animated version works will be difficult.

I know PNG is more efficient. Actually the workflow would lead over ffmpeg. The idea has been that the support of an image format as GIF would be maybe easier to solve for you than to switch to a video file format as MPEG. How difficult it would be for you, to implement the possibility to display animated images (GIF, MPEG, etc.) together with the standard PNG's? Meaning for example: First Layers normal PNG's then one layer which is a a "movie" in MPEG or GIF and so on. Data preparation is actually done with a small script on PC but also could be done on Raspbian

How fast you want to change frames?

Re: GIF Zip Import support

up to 15 frames per second, but thats not really the point, the important thing is, that it's converted to a playing movie without interruptions. The pictures are converted to a movie with 60Hz rate. I know well about capabilities of Nanodlp and it's already great and perfect for single projection (no problem to display up to approx. 2 frames/s incl. dynamic calculations and movement). But now to go one step ahaed the animated sequences are necessary to implement. It's not necessary that you provide all programming options, it would be just only great if you could provide the support of importing and displaying animated pictures, which could look the following:
0001.png
0002.png
....
0008.png
0009.mpeg
0010.png
etc.

For fullhd you can display 15 16fps on rpi using nanodlp.

Rpi version does not use xserver, so having animated frames will be very large feature to implement.

Re: GIF Zip Import support

This is why i thought the easiesiest would be to allow GIF format which includes also the animated GIF commands (show once, no loop, etc.)... I'll check shortly new, faster hardware and keep you updated about maximum fps rates thanks so far.
