Beta Version 2.9

For those for a capacity to play with the latest versions. I'm releasing a beta of version 2.9 today, which will roll out to become the main version next week.

To view the betas (in two forms), please goto:

• http://codecogs.izyba.com/components/equationeditor/equationeditor.php
• http://codecogs.izyba.com/components/eqneditor/editor.php

This update includes:

• Fast downloading, by reducing the size of the code downloaded. The HTML is lighter through the use of some new javascript that dynamically create more of the required actions; The javascript code is smaller through a variety of optimizations; and all javascript is now compressed to reduce size further.
• A new selector at the bottom of the screen, which can be used to choose between different output format. I.e. embedding equations into LaTeX, HTML, phpBB, TiddlyWiki, etc. This list will steadily increase as we adopt more platforms.
• The font styles are now written using their names, as in 'Bold', 'Italics' etc, The tool tip still shows an example using 'Abc 123'.
• The font for the main input box is now larger (12pt). While the fonts for the HTML code is smaller (9pt).

Bug fixes include:

• Fix for IE error which was showing the alt tags rather than the title tags as it should. When will MS learn!. This mean that those who wait long enough when hover over a button, will see a more informative description of the button (i.e. 'fraction', 'subscript' etc).
• Multiple fixes to the underlying javascript code, to make it more consistent in how and when it re-rendered the equations.
• Improvement in the 'tab' key override. It not only moves between curly brackets, {}, but after these it moves you to the end of the equation script, then it behaves like a normal tab key and moves you onto the next control.
• Errors in CSS are fixed.

Thanks for all the good suggestions and feedback - keep em coming. Hopefully we're well on the way to a very stable, multi-browser, platform.

Regards Will.

Hi Will,

Congratulations, both betas do seem quick and have a good solid feel about them. In my short evaluation no bugs reared their ugly heads:-)

Changes I like are the tab key which is a delight compared to the cursors keys. I think Clear button, clearing all including the rendered image, is the expected behaviour and is a good change.

I'm not sure what you intend to use the different versions for yet or whether it is a choice between the two.

I think the choice between different output formats is a good feature for the casual user. I can't say whether it would be common for someone to want to choose different formats during a single session; but, it is possible they might want to and in that respect it would be very handy for them being able to grab different formats without having to re-enter the equation.

Of course choices of format is redundant as far as my use in TiddlyWiki is concerned and I wonder if it could be omitted for that purpose if it is a choice between the two as I said above, since I really don't know if the different versions are for that purpose already.

All in all it's a job well done.

Hi,

Thanks for your testing. The two versions will be explained once I get the documentation up to date, but as you've guessed its mostly down to personal preference and application. If you're able to use the 'Copy to Document' button then you can use either version; however it you can't then you clearly need the yellow box at the bottom that shows the HTML code.

If I remember rightly, because you're our javascript code to launching the editor with something like

<a onclick="OpenLatexEditor('testbox','tw','')">Equation Editor</a>

Then this will open what I call the 'lite' version of the editor, which only differs from the 'normal' version by the lack of the yellow box for the HTML code at the bottom. You shouldn't need this, since when you click 'copy to document' it'll drop everything you need directly into document. I should add an option so you can choose the 'normal' version if for some reason you prefer this.

For those who can't get this level of integration then they need the 'normal' version.

Will.

Hi

Thought for the day! With images I am able to position them left right or central and it certainly improves the looks of some documents. Could there be a similar system for equations? I am perfectly happy with equations being written from the left margin but there are a few times when I feel that a short equation would look better centralised. For example:-

Line 1 x = bbbbbbbbb - right across the page .....

line 2 = 48.97

Small additional new feature, which is to allow people to get just the URL to an equation, without all the image tags associated with it.

Bug in the matrix panel also fixed.
