Also, the SHOW/HIDE and UPDATE buttons and window appear when unwanted when the src="ASCIIsvg.js" script is used with a transparent .png . It is possible to use segments of cubic Bezier curves with the control points used to match the slope of the adjacent segment and the curve, making the jipsen ASCIIsvg.js plot circumventable, although with a lot more work. Labels at any angle and equations then can be applied to the plot. Any diagram or plot that I can think of can therefore be rendered, albeit somewhat awkwardly at times. The plugins, scripts, tools and that are needed to acomplish this are pmathml.xsl (mathml.xsl ctop.xsl pmathmlcss.xsl) : ASCIIsvg.js ASCIIMathML.js d.svg ( required to make .png from non opaque .svg readable by IE 6 or .7z It appears that, as far as I can tell, that .png cannot layer over .svg in the predominant browser in use today, MS Internet Explorer. My friend, Chris Hartung, tells me it would violate the Pauli exclusion principle and Heisenberg uncertainty principle; however, he talks authoratatively at length about things that he does not have a complete understanding. Seriously however, Sam Fortiner, , says the IE has per-pixes alpha support is lacking. In conclusion, TeX and MathML can coexist under a transparent .png layer, but will be obscured by any .svg layer. Tex, MathML, .svg and .png can coexist in a document without layers, but for legends at an angle and TeX or MathML equations in a .svg or jipsen ASCIIsvg.js plot, it appears the now predominate browser cannot perform. Some combinations will work and others will not; when the Tex or MathML equations are put in a table with a transparent graphical .png layer over it the expression will be rendered properly with TeX and .svg in the table or with MathML and .png but not Tex with .png or MathML with .svg . Perhaps even now combinations can be found that will be more useful. The tools used to take up space to control the location of something are indirect at the present. David Siegel has a one pixel transparent .gif I have an 80x80 transparent .png with miniscule specks in the corner: t_8-trans.png and space_8-trans.png .
,   are not supported in .xml Presumably more advanced browsers will be developed to handle all useful combinations. Another option would be to use to execute the Jipsen JavaScript and intercept the .svg before the browser gets it, and then editing more things into it and converting it to a non-opaque .png; however, .see. may not yet be capable of this function. Other browsers and newer versions will undoubtedly include the capabilities that are provided now by third parties but for now the majority of browsers and be made to render technical literature without and bit maps, proprietary or captive formats, or monopolistic control of single sources with recurring license fees, with much less that a gigabyte of software as with the, latex foo.tex; dvips -E -y 2500 -o foo.eps foo2.eps; eps2eps -dNOCACHE foo.eps; inkscape -z -f foolsk -l foo.svg /Tex_live /Ghostscript /pstoedit /Inkscape $xx tools at , ,process which is now in the Inkscape menu.
