Create text on line ViewControl

[Ryan]

The PDF standard supports

Text Off Set
Font Color
Text Size

However, not aware of any PDF viewers actually supporting customizing Text Color and Text Size, not Adobe, nor any other major vendors.

So if you adjust Font Color and Text Size, and anyone later on adjusts the annotation, those customizations would be lost.

But if they are important for you then yes you would have to either make your own stream, or better yet, modify the default appearance. You could follow the examples in the forum post below to change the GState of any text to be the color you want. Adjusting the font size though would be much more complicated since it could overlap the line, or even be clipped by the annotation bounding box.

How can I add decorations to an annotation?

Another customer asked how to change the opacity of annotation? Some annotation types support this, so you would just call the API for that type. But some annotation types don’t support it, such as Sticky Note annots. So the following code shows this simpler customization to the default appereance. static public void ChangeOpacity(Annot annot, PDFDoc doc) { ElementReader reader = new ElementReader(); ElementWriter writer = new ElementWriter(); ElementBuilder builder = new ElementBuilder();…

Why is setting color and size important for your users (especially considering Adobe doesn’t support this)?
