semacode | Mirror of semacode gem with some 1.9 fixes

semacode is a C library. semacode has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

This Ruby extension implements a DataMatrix encoder for Ruby. It is typically used to create semacodes, which are barcodes, that contain URLs. This encoder does not create image files or visual representations of the semacode. This is because it can be used for more than creating images, such as rendering semacodes to HTML, SVG, PDF or even stored in a database or file for later use. See test.rb for an example of how to create a visual symbol for a semacode, it presents a semacode in HTML and plain text formats, and this can give you an idea of how to start. Once you have a visual representation of the semacode, you can use a reader, such as those from on your camera phone, to capture the URL embedded in the semacode and proceed directly to that web site.
