TeXCrop is a Web application for those who want to use TeX instead of MS Math Editor to write math formula in PowerPoint and Word. An alpha version is running at https://www.fukudat.com/texcrop/ . It's a clone of TeXclip.

I used to use TeXPoint when it was free, and TeXclip for a while after TeXPoint became shareware. I created TeXCrop since I wanted to have a few functions that TeXclip didn't have.

TeXCrop consists of a Web UI based on Dojo Toolkit and some back-end PHP application which invokes LaTeX, dvips, and convert to generate a PNG image.

TeXCrop is provided with NO WARRANTY. I welcome feedback from you (you can write comments to the discussion page, by clicking "discussion" tab on top of this page), but you may not expect any support from me.

How to use

Basics

Initial Screen
  1. Open TeXCrop with a Web browser.
  2. Input LaTeX source to the upper right pane.
  3. Click Create Image button in left pane. Then an image will be shown in the lower right pane.
  4. Finally,copy the image to your favorite application (e.g., PowerPoint, MS Word) by drag&drop or copy&paste.

On some combination of a Web browser and an operating system, either drug&drop or copy&paste doesn't work (i.e., the copied image becomes black). When you encounter such a problem, the following procedure may be a work-around:

  • Check Opaque background and create image, again.
  • Right click on the image to show a context-menu, select "download this image", and then load the downloaded image to your application.

Options

  • Resolution: specify a resolution in DPI of the image.
  • Font-Family: specify a font-family to be used in the image.
  • Bold-face by default: specify to use the bold face from the beginning. Of course, you can use \bf, \boldmath commands to specify font-weight.
  • Opaque background: By default, the image has the transparent background. When this option is specified, the background becomes white.

Specifying Colors

Color Palette
  • By using the color palette at the Editor's toolbar, you can specify a color to use. To do so, (1) select words (by the mouse) that you want to put colors, (2) pick a color in the color palette. Then you will find that the selected words has now the picked color.
  • By clicking "Create Image" button, you will have an image with the specified colors.
  • Note that a color specification must be within a meaningful block in the LaTeX syntax.
    When you encounter an error due to a color specification, try undo (Ctrl-Z or click undo button at the Editor's toolbar). Or, click Remove Color button to remove all the color specifications you entered and start over.
