4723: =item image_replication()
4724:
4725: =item resize_image()
4726:
4727: Get correct sizing parameter for an image given
4728: it's initial ht. and wid. This allows sizing of
4729: images that are generated on-the-fly (e.g. gnuplot)
4730: as well as serving as a utility for image_size.
4731:
4732: Parameter:
4733: height_param
4734: width_param - Initial picture dimensions.
4735: scaling - A scale factor.
4736: parstack, - the current stack of tag attributes
4737: from the xml parser
4738: safeeval, - pointer to the safespace
4739: depth, - from what level in the stack to look for attributes
4740: (assumes -1 if unspecified)
4741: cis - look for attrubutes case insensitively
4742: (assumes false)
4743:
4744: Returns:
4745: height, width - new dimensions.

4760:
4761: Converts a measurement in to mm from any of
4762: the other valid LaTeX units of measure.
4763: If the units of measure are missing from the
4764: parameter, it is assumed to be in and returned
4765: with mm units of measure
4766:

4770:
4771: Wrap image 'stuff' inside of the LaTeX required to implement
4772: alignment:
4773: align_tex_image(align, latex_rendering, image)
4774: Where:
4775: align - The HTML alignment specification.
4776: latex_rendering - rendering hint for latex.
4777: image - The LaTeX needed to insert the image itsef.
4778: width,height - dimensions of the image.
4779: Returns:
4780: The 1/2 wrapped image and the stuff required to close the
4781: wrappage. This allows e.g. randomlabel to insert more stuff
4782: into the closure.
4783:
4784:
4785: =item is_inside_of($tagstack, $tag)
4786: This sub returns true if the current state of Xml processing is inside of the tag.
4787: Parameters:
4788: tagstack - The tagstack from the parser.
4789: tag - The tag (without the <>'s.).
4790: Sample usage:
4791: if (is_inside_of($tagstack "table")) {
4792: I'm in a table....
4793: }

4796: HTML pages uploaded to a course which contain dependencies either from iframes,

4798: and PosterImageSrc) for which dependency is another file uploaded to the same
4799: course.
4800:
4801: Required input:
4802: href - dependency (either a relative URL, or an absolute URL)
4803: Optional inputs:
4804: docuri - URL of HTML page containing the dependency
4805: cdom - Course domain
4806: cnum - CourseID
4807:
4808: Output:
4809: returns an absolute URL constructed from the href provided, and the calling context.
1.454 raeburn 4810: (this will be null, if the URL does not begin: /uploaded/$cdom/$cnum/docs/ or
