In the rapidly evolving digital era, the need for accessibility in all forms of content, including PDFs, is increasingly crucial. To bridge the accessibility gap, setting alternate text within a PDF is a method that cannot be overlooked. This blog post provides a step-by-step guide to this process.
First Step: Tagging Images as Figure Tag
The initial approach to set alternate text involves ensuring that all the images in your PDF are tagged as a figure tag. Once they are tagged, simply navigate to the tags panel, right-click the figure tag, and select the properties button. This action opens up a section where you can input a description in the “alternate text for images” field.
Quick and Efficient Methods: Using the Accessibility Button
A faster way to set alternate text for multiple images simultaneously is by utilizing the ‘accessibility’ button. Clicking this option reveals an ‘Set alternate text’ command. Once activated, the system automatically detects all figures in the document and displays them alongside an associated text box.
This method streamlines the alternate text setting process and is particularly handy for documents containing numerous images.
The alternate text can be anything from a simple description of the image, like “a forest with Giant Sequoias” or “two robotic hands reaching towards each other,” to more complex annotations depending on the image’s content and context.
It’s vital to remember that images containing text should include the exact text as part of the alternate text, enhancing accessibility for visually impaired users who may rely on screen readers to access the document’s content.
Document Remediation: A Viable Alternate Option
Though learning to set alternate text within a PDF could be a valuable skill, you might prefer to invest your time elsewhere. For those who want to increase their PDF’s accessibility but don’t have the time or inclination to do it themselves, document remediation services are available.
These services take over the task of making a PDF accessible, freeing up your time for other endeavors. However, if you’re inclined to get your hands dirty and prefer doing it yourself, follow the steps outlined in this blog post or explore other resources for a more comprehensive learning experience.
