| org-create-formula-image is a compiled Lisp function in

|
| Create an image from LaTeX source using external processes.
|
| The LaTeX STRING is saved to a temporary LaTeX file, then

| =E2=80=98org-preview-latex-default-process=E2=80=99.
|
| The generated image file is eventually moved to TOFILE.
|
| The OPTIONS argument controls the size, foreground color and

|
| When BUFFER non-nil, this function is used for LaTeX previewing.
| Otherwise, it is used to deal with LaTeX snippets showed in
| a HTML file.
