Math & Science ⇒ Latex equation editor

[Gergö]

Hi,

I'm looking for an easy to handle offline latex equation editor, f. e. like this one:
https://www.codecogs.com/latex/eqneditor.php
but offline.
I'm not very familiar with the latex code so it should be a WYSIWYG-editor.
I need to save the formulas in PNG-format (or any other common bitmap or vector graphic format)
I tried lyx, but I cannot export the formulas as PNG

I would appreciate any recomendation!

Use LyX and creat a pdf. You just wrote a common vector-graphics-format is ok?

Hi Gergö,

welcome to the forum!

Believe me, the equation syntax is not hard to learn. Other general LaTeX things are harder.

How do you plan to use the result? In a Word document, or on the Internet? I ask because it may influence the choice of the output format, such as SVG which is scalable, and PDF too. I remember, the preview-latex package can export to PNG. The standalone class too, I just don't know yet how to describe the usage with LyX, as I'm a LaTeX user.

Hi Stefan,
I want to use the formulas on the internet. I guess PNG would be the best way, SVG might be an option too, but some older browsers don't support this format.
What do you mean by the "standalone class"?

[Gergö]

As I'm an absolute beginner it takes a long time for me to read and understand the documentation. I've checked that the preview and the standalone packages are already installed (MiKTeX package Manager). But I have no idea how to use them in LyX and how to export to PNG???

[Stefan Kottwitz]

Hmmm... check the menu Tools / Preferences / File / Formats / PNG, what you can set there, then use File / Export / PNG via the menu.

But a simple way would be to use any screenshot software.

Yes, I already tried that.
Unfortunately when I try to export as PNG it doesn't work:
"No information for exporting the format PNG"
???

The idea with the screenshot isn't that bad.

Thanks anyway!

I often make screenshots. Mark an area, click, save. Can be easier than exporting via some hard to open menu entry. And bitmap is bitmap, there's nothing to win via export over taking from the screen.

Just one exception: I noticed resolution issues with the Retina display on my Macbook, a screenshot was bigger than the original - in such a case I imported the PDF with Gimp, adjusting dpi resolution, and saved to PNG.

Just to mention that. A good screenshot tool is fine, there are some which allow to mark a screen area easily.
