The final step to creating a QR Code is to create the format and versionstrings, then place them in the correct locations in the QR code. This pageexplains how to generate the format and version strings, and illustrates where they are placed in the QR code.
Format String
The format information string encodes which error correction level and whichmask pattern is in use in the current QR code.Since there are four possible error correction levels (L, M, Q, and H)and eight possible mask patterns, there are 32 (4 times 8) possible formatinformation strings. The next section explains how to generate these formatstrings. For a complete list of the 32 format strings,please refer to the formatstring table. Facebook games win real money.
Generate the Format String
The format string is always 15 bits long. To create the string, you first create a five bit string that encodes theerror correction level and the mask pattern in use in this QR code.Then you use those five bits to generate ten error correction bits.The resulting fifteen bits are XORed with the mask pattern101010000010010. This process is explained in detail below.
The Error Correction Bits
The first step to creating the format string is to get the two bits that specify the error correction level in use in the QR code. The followingtable shows the bit sequences for each error correction level.
Error Correction Level | Bits | Integer Equivalent |
---|---|---|
L | 01 | 1 |
M | 00 | 0 |
Q | 11 | 3 |
H | 10 | 2 |
Notice that the numbers do not go in order of 0, 1, 2, 3 in thetable.
The Mask Pattern Bits
For the mask patterns, refer to the QR code mask patterns page to find the mask number that goes with each pattern. Convert the number intoa three-bit binary string.
Example Five Bit Format String
For example, if we have used error correction level L and mask pattern 4,the five-bit binary sequence is created like so:
Wizbet no deposit bonus code. 01 (indicator for error correction level L)
100 (binary for 4, i.e. mask pattern 4)
Result: 01100
100 (binary for 4, i.e. mask pattern 4)
Result: 01100
Generate Error Correction Bits for Format String
Now that we have five bits for the format string, we have to use it to generate ten error correction bits. This step uses Reed-Solomon ErrorCorrection, but it is a little easier becausein this case, the polynomials contain no more than fifteen terms, and their coefficients are all 1s or 0s.
Get the Generator Polynomial
When generating the format string's error correction codewords, the QR code specification says to use the following generator polynomial:
x10 + x8 + x5 + x4 + x2 + x + 1
x10 + x8 + x5 + x4 + x2 + x + 1
We can convert this to a binary string by taking only the coefficientsof each term. The coefficient of x10 is 1, the coefficientof x9 is 0 because x9 isn't present in the polynomial,and so on.
In other words, the binary string that represents the generator polynomialfor this step is
10100110111
10100110111
Calculate the Error Correction Bits
The next step is to divide the format string bits (01100 from the previousstep) by the generator polynomial (10100110111 from the previous step).
To do this, first create a 15-bit string by putting ten 0s to the right ofthe format string, like so:
01100 -> 011000000000000
01100 -> 011000000000000
Now remove any 0s from the left side:
011000000000000 -> 11000000000000
011000000000000 -> 11000000000000
Now we perform the division. The steps (described in more detail below) are:
1. Pad the generator polynomial string on the right with 0s to make it thesame length as the current format string.
2. XOR the padded generator polynomial string with the current format string.
3. Remove 0s from the left side of the result.
1. Pad the generator polynomial string on the right with 0s to make it thesame length as the current format string.
2. XOR the padded generator polynomial string with the current format string.
3. Remove 0s from the left side of the result.
We must divide the polynomials until the resulting format string is 10 or fewer bits long.Therefore, before each division step, check to makesure that the current format string is 11 bits or longer (11 bits is the lengthof the generator polynomial). Our current string,11000000000000, is 14 bits long.
First Division
First, pad the generator polynomial string on the right with 0s to make it the samelength as the current format string:
10100110111 <-- generator polynomial with no padding
11000000000000 <-- current format string as shown in previous section
10100110111000 <-- padded generator polynomial
10100110111 <-- generator polynomial with no padding
11000000000000 <-- current format string as shown in previous section
10100110111000 <-- padded generator polynomial
Now, XOR the format string with the padded generator polynomial:
11000000000000 ^ 10100110111000 = 01100110111000
11000000000000 ^ 10100110111000 = 01100110111000
And remove the 0s from the left side of the result:
01100110111000 -> 1100110111000
01100110111000 -> 1100110111000
Second Division
The resulting string 1100110111000is 13 bits long, so since that is 11 bits or longer,we can continue.
Pad the generator polynomial on the right to make the same length as thecurrent format string:
10100110111 <-- generator polynomial with no padding
1100110111000 <-- current format string
1010011011100 <-- padded generator polynomial
10100110111 <-- generator polynomial with no padding
1100110111000 <-- current format string
1010011011100 <-- padded generator polynomial
XOR the current format string with the padded generator polynomial:1100110111000 ^ 1010011011100 = 110101100100
Third Division
The resulting string 110101100100 is 12 bits long, so since that is 11bits or longer, we can continue.
Pad the generator polynomial on the right to make the same length as thecurrent format string:
10100110111 <-- generator polynomial with no padding
110101100100 <-- current format string
101001101110 <-- padded generator polynomial
10100110111 <-- generator polynomial with no padding
110101100100 <-- current format string
101001101110 <-- padded generator polynomial
XOR the current format string with the padded generator polynomial:110101100100 ^ 101001101110 = 011100001010 Minco 2 0 17 – minimalist time tracker.
And remove the 0s from the left side of the result:
011100001010 -> 11100001010
011100001010 -> 11100001010
Fourth Division
The resulting string 11100001010 is 11 bits long, so since that is 11bits or longer, we can continue.
There is no need to pad the generator polynomial, because the format stringis now the same length.
XOR the current format string with the generator polynomial:11100001010 ^ 10100110111 = 1000111101
The result is 10 bits long, so we are done with the division step.If the result were smaller than 10 bits, we would pad it on the LEFT with 0sto make it 10 bits long.
Put the Format and Error Correction Bits Together Lynn 1131.
Create a string using the original five bits of the format information(the error correction level indicator and the mask pattern indicator), followedby the error correction bits that we just generated.
The five-bit format string: 01100
The ten-bit error correction string from the division step: 1000111101
The combined string: 011001000111101
The ten-bit error correction string from the division step: 1000111101
The combined string: 011001000111101
XOR with the Mask String
The QR code specification says to XOR the result with the followingbinary string: 101010000010010
011001000111101 ^ 101010000010010 = 110011000101111
The final format string for acode with error correction level L and mask pattern 4 is 110011000101111
For a list of all 32 format strings, refer to theformat string table.
Put the Format String into the QR Code
The format information string is placed below the topmost finder patternsand to the right of the leftmost finder patterns, as shown in the image below.The number 0 in the image refers to the most significant bit of the format string, and the number 14 refers to the least significant bit.In other words,using the format string 110011000101111 from the example above,the numbers in the below image correspond to the format string bits as follows:
The image below shows the example format string, 110011000101111, in a version 1 QR code.
Dark Module
Every QR code must have a dark pixel, also known as a dark module, at the coordinates (8, 4*version + 9).That is, the y coordinate of the dark module is
version 1: 4*1 + 9 = 13
version 2: 4*2 + 9 = 17
version 3: 4*3 + 9 = 21
and so on.
version 1: 4*1 + 9 = 13
version 2: 4*2 + 9 = 17
version 3: 4*3 + 9 = 21
and so on.
This means that the dark module isalways to the right of the top right corner of the bottom-left finder pattern. This is shown in the image below.
For Bigger Codes
No matter what size the QR code is, the format string bits are placed below the topmost finder patterns and to the right of the leftmostfinder patterns, as illustrated below. Note that both images have the sameformat string, 110011000101111, from the example earlier on this page.The format string is highlighted in red, and the timing patternand dark module are highlighted in blue.
Version Information
If the QR Code is version 7 or larger, you must include an 18-bit version information string in the bottom left and top right corners of theQR code. (For a full list of all possible version information strings,refer to the format and version tables.)The version information areasare the 6x3 blue rectangles shown in the images below.The version information is placed beside the finder patterns no matter howlarge the QR code is. The image on the left is a version 7 code, and theimage on the right is a version 22 QR code.
Generating the Version Information String
The QR Code specification says touse the (18, 6) Golay code for the version information string.As such, the version information string is an 18 bit string that consists ofa six bit binary string that encodes the QR version, followed bya string of 12 error correction bits. The entire string is 18 bits long.
Get the Generator Polynomial
Any video converter pro 7 2 0 8. The QR code specification says to use the following generator polynomialfor this step:
x12 + x11 + x10 + x9 + x8 + x5 + x2 + 1
x12 + x11 + x10 + x9 + x8 + x5 + x2 + 1
As explained in the format string section earlier on this page, we can represent this generatorpolynomial with the following binary string:
1111100100101
1111100100101
Perform the Division
From here, we can follow the same division steps that we used to generate the format information string, except in this case wepad the initial strings to be 18 bits long rather than 15, and we stop when the current bit string is 12 or fewer bits long, rather than10 or fewer.
Start by making a six bit binary string that represents the version number.For example, for a version 7 code, the six bit binary equivalent of 7 is:
000111
000111
Turn this into an 18 bit string by padding on the right with 0s:
000111000000000000
000111000000000000
And remove the 0s from the left side:
111000000000000
111000000000000
Now pad the generator polynomial on the right with 0s to be the same length.
111000000000000 <-- version string
1111100100101 <-- generator polynomial with no padding
111110010010100 <-- padded generator polynomial
111000000000000 <-- version string
1111100100101 <-- generator polynomial with no padding
111110010010100 <-- padded generator polynomial
XOR the version string and padded generator polynomial:
1110000000000 ^ 111110010010100 = 110010010100
1110000000000 ^ 111110010010100 = 110010010100
This string is already the required length of 12, so there is no furtherdivision required. As with the format information string,if the result is smaller than 12, it must be padded on the LEFTwith 0s to make it 12 bits long.
Finally, put the original six bit version string to the left of the result from the last step.
version string: 000111
error correction string from above: 110010010100
final version information string: 000111110010010100
version string: 000111
error correction string from above: 110010010100
final version information string: 000111110010010100
For a full list of all possible version information strings,refer to the format and version tables.
