4903:
4904: =item resize_image()
4905:
4906: Get correct sizing parameter for an image given
4907: it's initial ht. and wid. This allows sizing of
4908: images that are generated on-the-fly (e.g. gnuplot)
4909: as well as serving as a utility for image_size.
4910:
4911: Parameter:
4912: height_param
4913: width_param - Initial picture dimensions.
4914: scaling - A scale factor.
4915: parstack, - the current stack of tag attributes
4916: from the xml parser
4917: safeeval, - pointer to the safespace
4918: depth, - from what level in the stack to look for attributes
4919: (assumes -1 if unspecified)
4920: cis - look for attrubutes case insensitively
4921: (assumes false)
4922:
4923: Returns:
4924: height, width - new dimensions.

4937:
4938: =item recalc()
4939:
4940: Converts a measurement in to mm from any of
4941: the other valid LaTeX units of measure.
4942: If the units of measure are missing from the
4943: parameter, it is assumed to be in and returned
4944: with mm units of measure

4946: =item LATEX_length()
4947:
4948: =item align_latex_image()
4949:
4950: Wrap image 'stuff' inside of the LaTeX required to implement
4951: alignment:
4952: align_tex_image(align, latex_rendering, image)
4953: Where:
4954: align - The HTML alignment specification.
4955: latex_rendering - rendering hint for latex.
4956: image - The LaTeX needed to insert the image itsef.
4957: width,height - dimensions of the image.
4958: Returns:
4959: The 1/2 wrapped image and the stuff required to close the
4960: wrappage. This allows e.g. randomlabel to insert more stuff
4961: into the closure.
4962:
4963:
4964: =item is_inside_of($tagstack, $tag)
4965: This sub returns true if the current state of Xml processing is inside of the tag.
4966: Parameters:
4967: tagstack - The tagstack from the parser.
4968: tag - The tag (without the <>'s.).
4969: Sample usage:
4970: if (is_inside_of($tagstack "table")) {
4971: I'm in a table....
