How to save an image from ETO?

Holo · July 2, 2020, 4:13pm

Do you know how I save out an image from the ETO?
I have a script that makes a sunstudy, but I could not figure out how to save that to a JPG or PNG.

It’s based on stuff from here

HI @Holo, after you captured and clicked the Close button, below will ask to save as png file:

def TestSampleEtoViewCaptureDialog():
    dialog = SampleEtoViewCaptureDialog();
    rc = dialog.ShowModal(Rhino.UI.RhinoEtoApp.MainWindow)
    if (rc):
        
        # get the bitmap from the dialog
        bitmap = dialog.Image()
        if not isinstance(bitmap, Eto.Drawing.Bitmap): return
        
        # prompt for file path
        filename = rs.SaveFileName ("Save", "PNG Files (*.png)|*.png||")
        if not filename: return
        
        # save it
        bitmap.Save(filename, Eto.Drawing.ImageFormat.Png)
        print "Bitmap written to: {}".format(filename)

You can also run this code from a button while the dialog is open of course.
