Differences between revisions 2 and 13 (spanning 11 versions)

EMAN2 includes a good selection of test images. They come in many shapes and forms, from simple gradients and shapes to basic noise models. To create a testimage start by running e2.py, and creating an empty image that is appropriately, for example as follows:

#] e2.py

Welcome to EMAN2
Prompt provided by IPython
Enter '?' for ipython help

In [3]: e = EMData()

In [4]: e.set_size(256,256)

Then issue of the command embedded below in the table to generate the pixel values

attachment:xcoord.png	attachment:ycoord.png
`e.process_inplace("testimage.gradient")`	`e.process_inplace("testimage.gradient", {'axis','y'})`
attachment:axes.png	attachment:circle.png
`e.process_inplace("testimage.axes")`	`e.process_inplace("testimage.circlesphere")`
attachment:scurve.png	attachment:gaussnoise_large.png
`e.process_inplace("testimage.scurve")`	`e.process_inplace("testimage.noise.gauss")`
