EDAS can generate PDF visa letters for authors of papers that have been accepted (or whose abstract has been accepted). The visa letter is defined as a template in Conference:Templates, using a restricted subset of XHTML or Wiki markup. Images, such as logos, must be uploaded via Conference:Web pages, using the "Upload assets" function.
The {signature} variable, included in the img tag, retrieves the signature file uploaded via Conference:Files.
Authors can then go to their paper page and generate a customized visa letter for each of their papers. The visa letter is returned to the author as a PDF file.
In the visa letter configuration, the conference can indicate that only authors who have paid their registration can download the visa letter.
