This rule checks that images of text are not used
|
|
|
|
This rule applies to any rendered image resources in a web page.
For each test target, at least one of the following is true:
- essential: the visible pixels of the test target contain text for which its presentation is essential; or
- language: the visible pixels of the test target do not contain text expressing anything in a human language; or
- significant: the visible pixels of the test target contain text and the text is not a significant part of the visible pixels of the test target; or
- decoration: the embedded image the test target belongs to is purely decorative.
- There is no mechanism to change the rendered text in the image resource. Otherwise, the rule might fail while SC 1.4.5 Images of Text and SC 1.4.9 Images of Text (No Exception) might be satisfied.
- The specific presentation of the text rendered in the image resource can be achieved through formatted text. Otherwise, the rule might fail while SC 1.4.5 Images of Text and SC 1.4.9 Images of Text (No Exception) might be satisfied.
No accessibility support issues known.
This rule is designed specifically for SC 1.4.5 Images of Text which includes exceptions to the images it applies to that are not part of SC 1.4.9 Images of Text (No Exception). Therefore, some images that are inapplicable for this rule can be applicable to SC 1.4.9 Images of Text (No Exception).
