This module defines the <gtext> tag that renders text into GIF images. For more information see the gtext page in the Web Site Creator manual.

Append .fmt (gif, jpeg etc) to all images

Append the default extension of the image format to all URLs generated by gtext.

Default maximum text-length

By default, the module will not try to render texts longer than this. The purpose of this is to prevent common coding errors such as mismatched tags from causing the graphics text module to parse the entire document. This can be overridden by using the "maxlen=..." attribute in the tag.

Normalize colors in parsed tags

Challenger can handle colors in many different formats, RGB (#rrggbb), CMYK (@c,m,y,k) and as English words (black). Not all versions of browsers support those color formats. If this variable is set the gtext module will convert the colors in the HTML tags specified in the Tags to parse for color variable to the RGB format (#rrggbb).

Parse tags for document colors

If set, parse the specified tags for document colors.

Tags to parse for color

When rendering an image it is important to know the background color. The gtext module can try to find out the background color by parsing HTML tags where you can set background color. This way the user does not have to explicitly set the background in the <gtext> tag. On the other hand, parsing all those tags will use CPU. Often more CPU than the actual image generation, since every one of these tags will be parsed for every RXML page, regardless of whether there are any <gtext> tags on the page or not.

If you later decide to change this variable to be more restrictive, some pages that rely on this feature might stop working. If you are concerned about CPU usage you should be restrictive from day one.

You will have to reload this module or restart Challenger to make changes to this variable take effect.
