4573: Tags Default Definition Module
4574:
4575: This is part of the LearningOnline Network with CAPA project
4576: described at http://www.lon-capa.org.

4586:
4587: =item image_replication()
4588:
4589: =item resize_image()
4590:
4591: Get correct sizing parameter for an image given
4592: it's initial ht. and wid. This allows sizing of
4593: images that are generated on-the-fly (e.g. gnuplot)
4594: as well as serving as a utility for image_size.
4595:
4596: Parameter:
4597: height_param
4598: width_param - Initial picture dimensions.
4599: scaling - A scale factor.
4600: parstack, - the current stack of tag attributes
4601: from the xml parser
4602: safeeval, - pointer to the safespace
4603: depth, - from what level in the stack to look for attributes
4604: (assumes -1 if unspecified)
4605: cis - look for attrubutes case insensitively
4606: (assumes false)
4607:
4608: Returns:
4609: height, width - new dimensions.

4622:
4623: =item recalc()
4624:
4625: Converts a measurement in to mm from any of
4626: the other valid LaTeX units of measure.
4627: If the units of measure are missing from the
4628: parameter, it is assumed to be in and returned
4629: with mm units of measure

4632:
4633: =item align_latex_image()
4634:
4635: Wrap image 'stuff' inside of the LaTeX required to implement
4636: alignment:
4637: align_tex_image(align, latex_rendering, image)
4638: Where:
4639: align - The HTML alignment specification.
4640: latex_rendering - rendering hint for latex.
4641: image - The LaTeX needed to insert the image itsef.
4642: width,height - dimensions of the image.
4643: Returns:
4644: The 1/2 wrapped image and the stuff required to close the
4645: wrappage. This allows e.g. randomlabel to insert more stuff
4646: into the closure.
4647:
4648:
4649: =item is_inside_of($tagstack, $tag)
4650: This sub returns true if the current state of Xml processing is inside of the tag.
4651: Parameters:
4652: tagstack - The tagstack from the parser.
4653: tag - The tag (without the <>'s.).
4654: Sample usage:
4655: if (is_inside_of($tagstack "table")) {
4656: I'm in a table....
