Success Criterion 1.
Soda PDF OCR
A document that consists of scanned images of text is inherently inaccessible because the content of the document is images, not searchable text.
Assistive technologies cannot read or extract the words; users cannot select, edit, resize, or reflow text nor can they change text and background colors; and authors cannot manipulate the PDF for accessibility.
For these reasons, authors should use actual text rather than images of text, using an authoring tool such as Microsoft Word or Oracle Open Office to author and convert content to PDF. If authors do not have access to the source file and authoring tool, scanned images of text can be converted to PDF using optical character recognition OCR.
Adobe Acrobat Pro can then be used to create accessible text. There are other software tools that perform similar functions.
See the list of other software tools in. This example uses a simple one-page scanned image of text.
To ensure that actual text is stored in the document, perform the following steps: Scan the document using as high a resolution as possible to improve the OCR performance. Load the scanned document in Acrobat Pro.
In the next dialog, select the All Pages radio button under Pages or Current Page if you are converting only one page , and then select OK. Under the Settings list, select Edit.
This is important for ensuring accessibility.
