What type of file can be stored in BARROCO CODE?
BARROCO CODE can store any type of file. This means that you can store every file types including text file (TXT), documents (DOC, XLS, HTML, PDF), compressed archives (ZIP, RAR, ACE), multimedia files like images (JPG, BMP, GIF).
 
Does BARROCO run on Windows XP or Windows NT?

 

Supported are all 32bit versions of MS Windows (95/XP/Vista/7 ).

 
What is capacity of BARROCO CODE?

 

Size of stored file is limited to 16000 elements (2890 KB).
Result size of BARROCO CODE depends on printing and scanning resolution, error correction level and size of stored file. If BARROCO code is greater than printing page, it is divided into more separated images (pages).

 

 
Maximal BARROCO CODE density?
300 DPI printing and scanning with default error correction level and redundancy is capacity 824 Bytes per square inch (55KB per page)

600 DPI printing and scanning with default error correction level and redundancy is capacity 1854 Bytes per square inch (121KB per page)

 
Why should I register?
BARROCO is released as shareware, allowing you to test it for a limited 30 days period. If you plan to continue using the program, you are required to register.
 
What happens to user if fail to register after 30 day trial period?
BARROCO is after few minutes automatically terminated. User can enter registration number.
 
Are there some limitations during trial period?
There are no limitations for using BARROCO in 30 days trial period. There is disabled additional labeling only.
 
I have installed BARROCO. What do I do now?
You can start generate BARROCO codes from selected files or decode BARROCO codes to files.
 
How can I use BARROCO code?

 

BARROCO code can store one file of any type.
You can - store files on paper (passwords, contacts), transport sensitive data on paper (DOC, PDF), send files by fax, print, scan and recover any type of file stored on paper, secure transfer encrypted and encoded files and transport color image printed on B&W paper

 
What is optimal scanning resolution?
Scanning resolution depends on size of pixels. Minimal recommended scanning resolution is 300 DPI, optimal is 600 DPI. Scan true color BARROCO code, crop it to its borders and decode with Barroco software.
If code can't be decoded, try scan it with greater resolution.
 
What is optimal scanning resolution for fax?
Normal fax resolution is 203x98 DPI, and HIGH fax resolution is 203x196 DPI. For fax, scan the document at 200 DPI or 400 DPI.
 
What is optimal image file format for storing BARROCO code?
You can store BARROCO code in one of supported file formats (PNG, JPEG, BMP, TIFF). Image can be converted to/from other image formats. The best for storing BARROCO codes is PNG format, there are smallest image files. You can decrease file size if you convert image to 2 colors (B&W).
 
Should I do some image correction before decoding?
No, you don't need any correction. For faster decoding speed is recommended crop BARROCO code.
 
Can BARROCO code store mp3 files?
BARROCO code can store any type of file. But due capacity and maximum limit (2890 KB), it is not primary use.
 
Can BARROCO code store more files?
BARROCO code can store only one file. But there is not restriction for file type. Therefore you can store archive (ZIP, RAR, ACE, ARJ, gz) with more compressed files.
 
What is maximal capacity for one page?
Minimal pixel size for 600DPI print is 4 pixels (121KB per A4 page) code should be scanned at 600DPI or more
 
Are indexes "drive letter dependant"?
No, if your drive letters are changed or indexes are moved to other computer, appropriate drives for indexes are detected.
 
Should I compress files before encoding?
You can encode any file type including ZIP, RAR, ACE. Smaller BARROCO codes can be created from standard archives (ZIP, RAR, ACE). BARROCO CODER has built in automatic compression. Some file types like text files can be successfully compressed to 20% of size. Compression is calculated before setting additional options, if compression is not required, it is disabled.
 
Are there some encryption or security features?
BARROCO CODER support standard encryption algorithm AES (Rijndael) with key length 160 bits. Key is generated from entered password. Encrypted is data stream and file name. You can't restore file without correct password. Minimal password length is 6 characters.
Stored file can be divided into two parts (two BARROCO code images). File can be reconstructed if are available both parts.
 
Can I decode encrypted BARROCO code without password?
NO, you can't decrypt and decode BARROCO code without correct password. There is no way to recover stored file. There is encrypted file stream and file name with AES algorithm with 160 bit key length.
 
How can I uninstall BARROCO?
Open the Control Panel, select "Add/Remove programs" option, and double-click BARROCO's entry on the list.
 
I think I have found a bug. Where and how can I submit reports about found problems?
