=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. |

|
| |
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.... |
| |
