# 15 works infinite with 8 images

# 12 seems to work fine with all images now, doing only gc.collect()

# 10-11 works infinite with 7 images but as soon as I add the next one (big PNG slide 2) it hangs memory alloc

# Makes semse because the error is:

# MemoryError: memory allocation failed, allocating 2518043 bytes

# So every new slide needs 2.5MB extra RAM!

# Fixed by adding lv.image.cache_drop(None) # This helps a lot!

# Now it works with 10M with infinite slides!

# Now not anymore... let's try increasing it.

#export HEAPSIZE=20M # this is fine for 1024x576

#export HEAPSIZE=15M # fine too

#export HEAPSIZE=32M # for 1280x720 images in the image viewer
