4900: Tags Default Definition Module
4901:
4902: This is part of the LearningOnline Network with CAPA project
4903: described at http://www.lon-capa.org.

4913:
4914: =item image_replication()
4915:
4916: =item resize_image()
4917:
4918: Get correct sizing parameter for an image given
4919: it's initial ht. and wid. This allows sizing of
4920: images that are generated on-the-fly (e.g. gnuplot)
4921: as well as serving as a utility for image_size.
4922:
4923: Parameter:
4924: height_param
4925: width_param - Initial picture dimensions.
4926: scaling - A scale factor.
4927: parstack, - the current stack of tag attributes
4928: from the xml parser
4929: safeeval, - pointer to the safespace
4930: depth, - from what level in the stack to look for attributes
4931: (assumes -1 if unspecified)
4932: cis - look for attrubutes case insensitively
4933: (assumes false)
4934:
4935: Returns:
4936: height, width - new dimensions.

4949:
4950: =item recalc()
4951:
4952: Converts a measurement in to mm from any of
4953: the other valid LaTeX units of measure.
4954: If the units of measure are missing from the
4955: parameter, it is assumed to be in and returned
4956: with mm units of measure

4958: =item LATEX_length()
4959:
4960: =item align_latex_image()
4961:
4962: Wrap image 'stuff' inside of the LaTeX required to implement
4963: alignment:
4964: align_tex_image(align, latex_rendering, image)
4965: Where:
4966: align - The HTML alignment specification.
4967: latex_rendering - rendering hint for latex.
4968: image - The LaTeX needed to insert the image itsef.
4969: width,height - dimensions of the image.
4970: Returns:
4971: The 1/2 wrapped image and the stuff required to close the
4972: wrappage. This allows e.g. randomlabel to insert more stuff
4973: into the closure.
4974:
4975:
4976: =item is_inside_of($tagstack, $tag)
4977: This sub returns true if the current state of Xml processing is inside of the tag.
4978: Parameters:
4979: tagstack - The tagstack from the parser.
4980: tag - The tag (without the <>'s.).
4981: Sample usage:
4982: if (is_inside_of($tagstack "table")) {
4983: I'm in a table....
