Description
This template is a specialized template to render a specific kind of microscopic photos by T. Gräfenhan. The images have a maximum size of 2560px if uncropped, but may be cropped. The major function of this template is to calculate a scale bar correctly for the magnification factors embedded in the file name.
Parameters
- width: either number + px for fixed width in pixel, or number, interpreted as percentage relative to original size.
- caption: You must pass the caption in a named parameter!
- a sequence of unnamed parameters, covering the standard image functionality (thumb, left, caption, etc.).
Usage
- {{ImageTG|File:x.png|caption=Your caption text here|width=250px}}
- Fully equivalent to: [[File:x.png|250px|Your caption text here]]
- {{ImageTG|File:x.png|thumb|left|width=15|upright|caption=Your caption text}}
- This scales the image to 15% of original size.
Dependendencies
Depends on Extension:StringFunctions, Extension:MediaFunctions, Extension:Variables.
