You can pass images created with the <samp class="codeph">cfimage</samp> tag to <samp class="codeph">Image</samp><samp class="codeph">ImageNew</samp> function. The following table groups the <samp class="codeph">Image</samp> functions by category:</font> functions or create images with the </h2>">

    ColdFusion image functions do not have a rich text renderer, so that is something completely unsupported.

    One solution would (have) be(en) trying ColdFusion's PDF functionality, since it can render rich text. Then you would want to create an image of the PDF, and paste it into your original image with imagePaste().

    However, Adobe has been careful not to allow you to do this. You cannot convert PDFs to images. The thumbnails CFPDF creates are way too small. In addition, CFDOCUMENTs "scale" attribute keeps the text rendered very small, not allowing values over 100. Third, creating transparent thumbnails doesn't work for me at least - the white default background is always there.

    Suggestions:

    * Ditch the idea about rendering rich text. Write headers and text  separately with different font style, and leave it there.

    * Find an external third party component for this. ImageMagick is free, and can convert PDFs into images. You might have still problems with the image transparency and anti-aliasing.

    * Use a third party RTF-to-image renderer. Commercial applications (at least for Windows) exist.
