Sinopsis

Este comando abre un letrero de diálogo para guardar el contenido actual de la vista 3D en un archivo que puede ser de diversos formatos de imagen. Adicionalmente, puedes cambiar el ratio de aspecto y la resolución de la captura de pantalla utilizando el botón de "Opciones" para tener acceso a más parámetros.

Este comando también puede utilizar el campo de comentario de imagen de algunos tipos de imágenes, como PNG o JPEG para guardar información MIBA con la imagen.


Image formats

FreeCAD uses the QT built-in image types and some QT plugins in the bin/imageformats directory to save pictures. So how many and what formats you can choose depends on your platform.

Dialog


Image Size

The image size parameters are set to the screen size of the active 3D view. But you can change it to any value you like. Some OpenGL drivers don't allow renderings greater then 8000 pixels. It depends on your system.

With the four buttons you can change the aspect to a certain value.

Image background

With this combo box you can choose the background of the picture you make.

  • Current use the current view background (as chosen in the preferences)
  • White creates a plain white background (for e.g. printings)
  • Black plain black background
  • Transparent creates a transparent background on image formats which support transparency
Comment

Some image formats can transport a comment along the picture. In case you choose one of this formats you can insert a comment or use the comment field for the MIBA information.

Scripting

It's also possible to save the screen by python:

 Gui.ActiveDocument.ActiveView.saveImage('C:/temp/test.png',1656,783,'Current')

This script makes a series of pictures of different sizes and from different points of view. The type of the camera, i.e. orthographic or perspective can also be changed.

 import Part,PartGui
 # loading test part
 Part.open("C:/Documents and Settings/jriegel/My Documents/Projects/FreeCAD/data/Blade.stp")
 OutDir = 'c:/temp/'
 
 # creating images with different Views, Cameras and sizes
 for p in ["PerspectiveCamera","OrthographicCamera"]:
   Gui.SendMsgToActiveView(p)
   for f in ["ViewAxo","ViewFront","ViewTop"]:
     Gui.SendMsgToActiveView(f)
     for x,y in [[500,500],[1000,3000],[3000,1000],[3000,3000],[8000,8000]]:
       Gui.ActiveDocument.ActiveView.saveImage(OutDir + "Blade_" + p +"_" + f + "_" + `x` + "_" + `y` + ".jpg",x,y,"White")
       Gui.ActiveDocument.ActiveView.saveImage(OutDir + "Blade_" + p +"_" + f + "_" + `x` + "_" + `y` + ".png",x,y,"Transparent")
 
 # close active document
 App.closeDocument(App.ActiveDocument.Name)
