Slow, primitive, and wasteful but it works
--image save and load
function setup()
--make image
myimage = image(10,10)
for i = 5, 10 do
for j = 1, 10 do
myimage:set(i,j,math.random(256),math.random(256),math.random(256),255)
end
end
--saveimage
saveimage = myimage.width .. "," .. myimage.height .. ","
for i = 1, myimage.width do
for j = 1, myimage.height do
a,b,c,d = myimage:get(i,j)
saveimage = saveimage .. a .. "," .. b .. "," .. c .. "," .. d .. ","
end
end
saveLocalData("x",saveimage)
--loadimage
loadimage = readLocalData("x")
k = 1
l = string.find(loadimage,",",k)
lw = string.sub(loadimage,k,l-1)
lw = lw + 0
k = l + 1
l = string.find(loadimage,",",k)
lh = string.sub(loadimage,k,l-1)
k = l + 1
loadedimage = image(lw,lh)
for i = 1, lw do
for j = 1, lh do
l = string.find(loadimage,",",k)
a = string.sub(loadimage,k,l-1)
k = l + 1
l = string.find(loadimage,",",k)
b = string.sub(loadimage,k,l-1)
k = l + 1
l = string.find(loadimage,",",k)
c = string.sub(loadimage,k,l-1)
k = l + 1
l = string.find(loadimage,",",k)
d = string.sub(loadimage,k,l-1)
k = l + 1
loadedimage:set(i,j,a,b,c,d)
end
end
end
function draw()
rect(0,0,10,10)
background(0, 0, "095")
scale(10)
sprite(myimage,10,10)
sprite(loadedimage,30,30)
end
Edit: that’s not a comment on the image command, it’s a comment on this method I wrote.
This is a bridge until a real format can be used.
