i tried this
convert w1.png -format %c -depth 8 histogram:info:-
on my transparent png and got this
988644: ( 0, 0, 0, 0) #00000000 none
1019: ( 0, 0,255,255) #0000FF blue

try this, it works for me on IM 6.7.0.2 Q16 Mac OSX Tiger. Note I renamed your images for simplicity.


convert -delay 200 1.png 2.png -loop 0 miff:- |\
convert - -draw 'image DstOver 0,0 0,0 "3.gif"' \
-layers Optimize 4.gif

well i gave it a try but after 5 minutes of 100% of one of my CPUs i ...

Lets go back to square one.

Explain what you mean by reduce the size of the gif. Do you mean file size or image size?

Furthermore, why do you think using and (32-bit color) transparent ...

i create the images using System.Drawing.Bitmap
i set the pixels of the little dots to whatever colour
then save it as png
if i edit that then it shows as transparent
i guess the background is black and transparent because it is 0,0,0,0 (ARGB) and the little dots are 255,x,x,x (ARGB)
so
i created a ...

well i tried a
convert backgroundGrid.gif -monochrome backgroundGrid2.gif
thinking i would get only black and white
not perfect but worth a test
however i got a pure black image (i guess the grey was less than 50%)
and i tried that as the background
convert -dispose previous -delay 200 -loop 0 w ...

the lines aren't but upon closer inspection

so i did a
convert backgroundGrid.gif -colorspace Gray backgroundGrid2.gif

then
convert -dispose previous -delay 200 -loop 0 w*.png w.anim.gif
convert backgroundGrid2.gif w.anim.gif -loop 0 w.anim.gif

but still got ...

i read all of those :-)
that is where i got the bit about putting the background in last and making the others transparent
my images have 19 colours + transparent + black(for the background) + grey(for the lines)
they are created using setpixel on a 1000x1000 canvas with no effects or aliasing
that ...
