Python "it" Scripting

View Code:



Histograms displayed by digital cameras and applications such as PhotoShop offer a convenient way of judging the distribution of brightness in an image. The python code presented in lising 1 adds a new item to the Commands menu of 'it', figure 1, that will display a histogram of the current catalog image in a Firefox browser.

Figure 1

The Histogram command saves, in a directory named "histogram" in the current Maya project folder, a web page and two images. After saving the files the Histogram command opens the web page using Firefox. For example, the histogram of the rendered image shown in figure 1 can be viewed here,

A histogram of the same image displayed by the PhotoShop's,
menu is shown next. The histogram generated by the Histogram python code will, in general, closely match Photoshop's "Levels" of the same image.
