ZQL - Zero Quality Loss

[Thijs]

Hey there! Meanwhile I was offline for a very long time, I've done a lot of stuff.
But the biggest thing I've made was my own image-compression.
I'm not showing the source code, I'm sorry, but I can show you a video of what I've made on my pc.

Video: www.youtube.com/watch?v=4AzydFQTQ0Q

I've also made a version for TouchLua.

O-kay.

I looked at the default rank names and the next rank is named "God".

Could you try not to say what you have achieved when replying to someone else's threads? 
Please post your achievements seperately, write a thread about it.   It's kind of annoying me..
I got 2 replies to ZQL now, both about something else..

Really?

Actually I did, but you weren't here at the time.

Besides, you've posted OT things before, don't blame me for a *single* incident.

Anywaaaay this ZQL stuff seems pretty cool, could you elaborate on how it works?

Hold on, I'm going to try and explain.

Tx, well you know every 'character' has it's own bytecode.
Color value's range from 0-255, so 256 different value's a color.
R-G-B, 3 colors, 256^3=16777216 different colors.
But because the bytecode only ranges from 1-255 (byte 0 is anoying cos it removes every byte in front of it..) I'll have to store 4 different value's instead of 3. (ZQL doesn't yet support opacity/transparency..).
It's difficult to explain.
The 1st token holds a combination of numbers for R-G-B to add a value to.
Very hard to explain. For instance:
local cdl={['n0']='a',['n1']='b',['n2']='c',['n3']='d',['n4']='e',['n5']='f',['n6']='g',['n7']='h',['n8']='i',['n9']='j',['n10']='k',['n11']='l',['n12']='m',['n13']='n',['n14']='o',['n15']='p',['n16']='q',['n17']='r',['n18']='s',['n19']='t',['n20']='u',['n21']='v',['n22']='w',['n23']='x',['n24']='y',['n25']='z',['n26']='A',['n27']='B',['n28']='C',['n29']='D',['n30']='E',['n31']='F',['n32']='G',['n33']='H',['n34']='I',['n35']='J',['n36']='K',['n37']='L',['n38']='M',['n39']='N',['n40']='O',['n41']='P',['n42']='Q',['n43']='R',['n44']='S',['n45']='T',['n46']='U',['n47']='V',['n48']='W',['n49']='X',['n50']='Y',['n51']='Z',['n52']='0',['n53']='1',['n54']='2',['n55']='3',['n56']='4',['n57']='5',['n58']='6',['n59']='7',['n60']='8',['n61']='9',['n62']='-',['n63']='/',['n64']=':',['n65']=';',['n66']='(',['n67']=')',['n68']='&',['n69']='@',['n70']='"',['n71']='.',['n72']=',',['n73']='?',['n74']='[',['n75']=']',['n76']='{',['n77']='}',['n78']='#',['n79']='%',['n80']='^',['n81']='*',['n82']='+',['n83']='=',['n84']='<',['n85']='>'}
The color: rgb(187,186,142)

Is 187 less than 86? Nope. R-Step0
Is 187 greater than 85? Yep. R-Step1
Is 187 greater than 170? Yep. R-Step2

Bottom-Value-R=2 (Greater than 85*2)

Is 186 less than 86? Yep. G-Step0.
Is 186 greater than 85? Yep. G-Step1.
Is 186 greater than 170? Yep. G-Step2.

Bottom-Value-G=2 (Greater than 85*2)

Is 142 less than 86? Nope. B-Step0.
Is 142 greater than 85? Yep. B-Step1.
Is 142 greater than 170? Nope. B-Step2.

Bottom-Value-B=1 (Greater than 85, but less than 85*2)

Bottom-Value-ID=221

Search for ID in list:

bvdl={['000']='a',['001']='b',['002']='c',['010']='d',['011']='e',['012']='f',['020']='g',['021']='h',['022']='i',['100']='j',['101']='k',['102']='l',['110']='m',['111']='n',['112']='o',['120']='p',['121']='q',['122']='r',['200']='s',['201']='t',['202']='u',['210']='v',['211']='w',['212']='x',['220']='y',['221']='z',['222']='A'}

Now we see the token/character for this bottom-value-combination is 'z'.

Now the bottom value's are:

For R: 171
For G: 171
For B: 86

Now we want to know the 'difference' between the R-G-B value's and their bottom-value's.

delta_R=187-171=16
delta_G=186-171=15
delta_B=142-86=56

Now let's see what is their token in list:

local cdl={['n0']='a',['n1']='b',['n2']='c',['n3']='d',['n4']='e',['n5']='f',['n6']='g',['n7']='h',['n8']='i',['n9']='j',['n10']='k',['n11']='l',['n12']='m',['n13']='n',['n14']='o',['n15']='p',['n16']='q',['n17']='r',['n18']='s',['n19']='t',['n20']='u',['n21']='v',['n22']='w',['n23']='x',['n24']='y',['n25']='z',['n26']='A',['n27']='B',['n28']='C',['n29']='D',['n30']='E',['n31']='F',['n32']='G',['n33']='H',['n34']='I',['n35']='J',['n36']='K',['n37']='L',['n38']='M',['n39']='N',['n40']='O',['n41']='P',['n42']='Q',['n43']='R',['n44']='S',['n45']='T',['n46']='U',['n47']='V',['n48']='W',['n49']='X',['n50']='Y',['n51']='Z',['n52']='0',['n53']='1',['n54']='2',['n55']='3',['n56']='4',['n57']='5',['n58']='6',['n59']='7',['n60']='8',['n61']='9',['n62']='-',['n63']='/',['n64']=':',['n65']=';',['n66']='(',['n67']=')',['n68']='&',['n69']='@',['n70']='"',['n71']='.',['n72']=',',['n73']='?',['n74']='[',['n75']=']',['n76']='{',['n77']='}',['n78']='#',['n79']='%',['n80']='^',['n81']='*',['n82']='+',['n83']='=',['n84']='<',['n85']='>'}

Now we see:
R='n16'='q'
G='n15'='p'
B='n56'='4'

The stored code for 'rgb(187,186,142)' is: zqp4

The only problem: If i want to save images which are like 650*650 pixels then Lua is crying about constant table overflows ;( XD

Try tail calling

Its about a table, not a function, and if I want to edit my images I'll have to be able to search pixels from the table. 

[warspyking]

Hmm I'm really curious, could you give me reproduction steps for the table overflow?
