Re: Converting to HTML

[Pavel Sanda]

 My question is whether I can insert a command that will appear in the 
 header of an .html file created by LyX. I'd like to do it through the 
 document settings or other means. Some background follows.

you can define your own script converting tex-html.

in preamble you will add some tex comment which does not change anything wrt
tex output but will be cought by your script. in case such comment is detected
you just pass the control to the previous script _and_ change the output file.

 I want to put some sort of security on the web versions to at least make it 
 difficult to print the file. When I used OpenOffice, I could save a .pdf 
 that required a password for printing.

don't see how to do directly inside lyx, but iirc pdftk utilities do this job,
so with some tweaking of your export scripts this could be automatized too.

With LyX, I didn't see how to do 
 this, but I inserted the lines:

 style media=print

 body {display: none;}

  /style

imho these attempts to secure docs against printing are just waste of your time,
only very weak students dont find way how to put it in print.

Hi Stephen,

Thanks for the quick reply.  I ran the command line htlatex, and it  
appeared to create similar files as when I originally tried it (using  
the export html menu item). There were no png files created at all.  
There were none in the same directory (as referenced in the html  
file), and I tried a search for the name, but found nothing. PDF  
seems to display fine...


Actually, reading the terminal output, there are a whole lot of error  
messages around the png conversion stage, for example:


System call: convert -trim +repage -density 110x110 -transparent

I suppose I didn't download some part that I was meant too, but I had

That is how htlatex works. It converts most equations to
png files. These filenames are embedded in the body of the 
html code. The png files need to go with the html file. Or the

browser can't locate the png files to display them in the places
they occur in the html doc which gets represented in the browser.
I think you may need to know how html works.

Tetex or Miktex is a must have and it does some conversions
with epstopdf and sometimes Ghostscript does conversions.
Python, and also sed.exe , sh.exe , are needed, Aspell optional.

How about ImageMagick, that has a convert.exe, did you
install that yet? Remember to run LyX-Reconfigure if a
new program is installed that you want LyX to recognize.

There are several options to generate html from latex files.  You should be
able to use tth (I gather this is a Windows machine, which I know little

there probably is), which does not generate bitmap graphics of mathematical

LyX should be able to be re-configured to use tth instead of whatever you are

LyX uses the ImageMagick convert utility to convert between graphics 
formats (in this case, from Postscript to PNG).  The error message 
indicates convert was not found.  So the first question is, did you 
install ImageMagick?  If yes, then make sure its directory is on the 
path prefix (Edit-Preferences-Paths-PATH prefix).

Thanks to everyone that helped me out, it *was* (the lack of)  
ImageMagick in the end that caused the problems. I thought I had  
installed it, but due to dependencies and the order I installed (I  
suppose), it didn't work the first time.


I attempted the tth-converted file David sent me, but unfortunately  
it was no good on my palm, using Plucker, with strange formatting  
such as odd ruled-line breaks mid-formulae. (It *is* only palm v.4,  
so perhaps I am limited in my options.)


I did have the default htlatex working reasonably well, but on my  
palm I appear to run into two other problems.


1. The code I use for nesting a list item *on the same line* as an  
itemize item doesn't translate. I use the ERT code {} within an  
itemise paragraph, and then the list environment on the next (nested  
right one), which displays fine on pdf, but converts onto the next  
line on all html. (This is a relatively minor issue.)


2. Certain characters don't seem to work on my palm (possible de- 
encoding issues?). For example, instead of a dot product sign, I get  
#x00D7; and other symbols such as theta are similarly represented.  
I know this is probably just issues with my (old) palm's programs  
(Plucker), but would there be a way to force htlatex to encode more  
primitively and convert more symbols to png?


Thanks,
Lee.

There were none in the same directory (as referenced in the html  
file), and I tried a search for the name, but found nothing. PDF

Actually, reading the terminal output, there are a whole lot of error  
messages around the png conversion stage, for example:


System call: convert -trim +repage -density 110x110 -transparent

sh: line 1: convert: command not found

another look and couldn't see anything obvious. Any hints?


Thanks again,

Hi,


I can export fine, but the html file appears to reference  
several .png files for some of the mathematical symbols that aren't  
created. I thought it might have had something to do with not having  
libpng, so i got that too, but that made no difference.




That is how htlatex works. It converts most equations to
png files. These filenames are embedded in the body of the 
html code. The png files need to go with the html file. Or the

browser can't locate the png files to display them in the places
they occur in the html doc which gets represented in the browser.
I think you may need to know how html works. 


Thanks,
Lee.

Tetex or Miktex is a must have and it does some conversions
with epstopdf and sometimes Ghostscript does conversions.
Python, and also sed.exe , sh.exe , are needed, Aspell optional.

How about ImageMagick, that has a convert.exe, did you
install that yet? Remember to run LyX->Reconfigure if a
new program is installed that you want LyX to recognize.

You need ImageMagick. Either fink or i-Installer will let you install  
it easily.

There are several options to generate html from latex files.  You should be
able to use tth (I gather this is a Windows machine, which I know little
about, but check the tth website to see whether there is a Windows version;
there probably is), which does not generate bitmap graphics of mathematical
expressions; it does it all in (really ugly code) html, and it displays quite
nicely on most browsers.  It is at least worth a try.  One thing to check is
how whatever browser you have with the PDA handles the code.  I will send you
a sample output by e-mail.

LyX should be able to be re-configured to use tth instead of whatever you are
using.

LyX uses the ImageMagick convert utility to convert between graphics 
formats (in this case, from Postscript to PNG).  The error message 
indicates convert was not found.  So the first question is, did you 
install ImageMagick?  If yes, then make sure its directory is on the 
path prefix (Edit->Preferences->Paths->PATH prefix).

Thanks to everyone that helped me out, it *was* (the lack of)  
ImageMagick in the end that caused the problems. I thought I had  
installed it, but due to dependencies and the order I installed (I  
suppose), it didn't work the first time.


I attempted the tth-converted file David sent me, but unfortunately  
it was no good on my palm, using Plucker, with strange formatting  
such as odd ruled-line breaks mid-formulae. (It *is* only palm v.4,  
so perhaps I am limited in my options.)


I did have the default htlatex working reasonably well, but on my  
palm I appear to run into two other problems.


1. The code I use for nesting a list item *on the same line* as an  
itemize item doesn't translate. I use the ERT code "{}" within an  
itemise paragraph, and then the list environment on the next (nested  
right one), which displays fine on pdf, but converts onto the next  
line on all html. (This is a relatively minor issue.)


2. Certain characters don't seem to work on my palm (possible de- 
encoding issues?). For example, instead of a dot product sign, I get  
"" and other symbols such as theta are similarly represented.  
I know this is probably just issues with my (old) palm's programs  
(Plucker), but would there be a way to force htlatex to encode more  
primitively and convert more symbols to png?


Thanks,
Lee.
