Images used in an open textbook project should be in either PNG, GIF or JPEG  format. PNG is the preferred image type. If you use Visio to create images, you must export the images as one of these file formats.<\/p>\n

Other useful platforms & tools for adapting open textbooks<\/h2>\n

If you wish to adapt an open textbook, you need to be able to have the textbook in a technical format that you can work with. This usually means the original source files used to create the textbook.<\/p>\n

Common source formats for open textbooks that you should look for are:<\/p>\n

\n
• HTML files (webpages)<\/li>\n
• Word or OpenOffice documents<\/li>\n
• Text files<\/li>\n
• ePub<\/li>\n
• LaTex files (if the original book includes math or science formulas and equations).<\/li>\n<\/ul>\n

  What tools you will use to create your version of the textbook will depend greatly on what format you find the original textbook in and what you feel comfortable working with.<\/p>\n

  PDF documents. Great to distribute, terrible for editing.<\/strong>
  \nIt is common that open textbooks may only be available as a PDF document. PDF documents are great formats to distribute the final version of the textbook to students in, but a terrible format for editing or adapting. If you want to adapt an open textbook that is only available in PDF format, you will need to convert the PDF document to one of the formats above. However, converting a PDF document to an editable format is a difficult, time consuming and an imprecise process that requires specialized tools that don’t always do the job. Therefore, if you are faced with the task of modifying a PDF document, before you consider converting that PDF to an editable document,  you should contact the original author and ask for a copy of the textbook source files.<\/p>\n

  Other editing tools<\/h3>\n

  The chart below shows you some of the tool options you have for working with the various file formats. Note that this is not an exhaustive list. You may have a tool that works for you that you wish to use to create your open textbook.<\/p>\n\n\n\n\n\n\n\n\n\n
