|

|
=item image_replication() |
|
|
|
=item resize_image() |
|
|
|
Get correct sizing parameter for an image given |
|
it's initial ht. and wid. This allows sizing of |
|
images that are generated on-the-fly (e.g. gnuplot) |
|
as well as serving as a utility for image_size. |
|
|
|
Parameter: |
|
height_param |
|
width_param - Initial picture dimensions. |
|
scaling - A scale factor. |
|
parstack, - the current stack of tag attributes |
|
from the xml parser |
|
safeeval, - pointer to the safespace |
|
depth, - from what level in the stack to look for attributes |
|
(assumes -1 if unspecified) |
|
cis - look for attrubutes case insensitively |
|
(assumes false) |
|
|
|
Returns: |
|
height, width - new dimensions. |

=item recalc() |
|
|
|
Converts a measurement in to mm from any of |
|
the other valid LaTeX units of measure. |
|
If the units of measure are missing from the |
|
parameter, it is assumed to be in and returned |
|
with mm units of measure |
|
|
|
=item LATEX_length() |
|
|
|
=item align_latex_image() |
|
|
|
Wrap image 'stuff' inside of the LaTeX required to implement |
|
alignment: |
|
align_tex_image(align, latex_rendering, image) |
|
Where: |
|
align - The HTML alignment specification. |
|
latex_rendering - rendering hint for latex. |
|
image - The LaTeX needed to insert the image itsef. |
|
width,height - dimensions of the image. |
|
Returns: |
|
The 1/2 wrapped image and the stuff required to close the |
|
wrappage. This allows e.g. randomlabel to insert more stuff |
|
into the closure. |
|
|
|
|
|
=item is_inside_of($tagstack, $tag) |
|
This sub returns true if the current state of Xml processing is inside of the tag. |
|
Parameters: |
|
tagstack - The tagstack from the parser. |
|
tag - The tag (without the <>'s.). |
|
Sample usage: |
|
if (is_inside_of($tagstack "table")) { |
|
I'm in a table.... |
|
} |
|
|
|
=item clean_docs_httpref($href,$docuri,$cdom,$cnum) |
|
HTML pages uploaded to a course which contain dependencies either from iframes, |
|
javascript files or objects (FlashPlayerSwf, MediaSrc, XMPSrc, ConfigurationSrc, |
|
and PosterImageSrc) for which dependency is another file uploaded to the same |
|
course. |
|
|
|
Required input: |
|
href - dependency (either a relative URL, or an absolute URL) |
|
Optional inputs: |
|
docuri - URL of HTML page containing the dependency |
|
cdom - Course domain |
|
cnum - CourseID |
|
|
|
Output: |
|
returns an absolute URL constructed from the href provided, and the calling context. |
|
(this will be null, if the URL does not begin: /uploaded/$cdom/$cnum/docs/). |
