4905: =item image_replication()
4906:
4907: =item resize_image()
4908:
4909: Get correct sizing parameter for an image given
4910: it's initial ht. and wid. This allows sizing of
4911: images that are generated on-the-fly (e.g. gnuplot)
4912: as well as serving as a utility for image_size.
4913:
4914: Parameter:
4915: height_param
4916: width_param - Initial picture dimensions.
4917: scaling - A scale factor.
4918: parstack, - the current stack of tag attributes
4919: from the xml parser
4920: safeeval, - pointer to the safespace
4921: depth, - from what level in the stack to look for attributes
4922: (assumes -1 if unspecified)
4923: cis - look for attrubutes case insensitively
4924: (assumes false)
4925:
4926: Returns:
4927: height, width - new dimensions.

4940:
4941: =item recalc()
4942:
4943: Converts a measurement in to mm from any of
4944: the other valid LaTeX units of measure.
4945: If the units of measure are missing from the
4946: parameter, it is assumed to be in and returned
4947: with mm units of measure

4949: =item LATEX_length()
4950:
4951: =item align_latex_image()
4952:
4953: Wrap image 'stuff' inside of the LaTeX required to implement
4954: alignment:
4955: align_tex_image(align, latex_rendering, image)
4956: Where:
4957: align - The HTML alignment specification.
4958: latex_rendering - rendering hint for latex.
4959: image - The LaTeX needed to insert the image itsef.
4960: width,height - dimensions of the image.
4961: Returns:
4962: The 1/2 wrapped image and the stuff required to close the
4963: wrappage. This allows e.g. randomlabel to insert more stuff
4964: into the closure.
4965:
4966:
4967: =item is_inside_of($tagstack, $tag)
4968: This sub returns true if the current state of Xml processing is inside of the tag.
4969: Parameters:
4970: tagstack - The tagstack from the parser.
4971: tag - The tag (without the <>'s.).
4972: Sample usage:
4973: if (is_inside_of($tagstack "table")) {
4974: I'm in a table....
