==Описание==


The '''Std ViewScreenShot''' command opens a dialog box to create an image file, a screenshot, from the active [[3D_view|3D view]].
==== Synopsis ====
This command opens a dialog to save the current content of the 3D view to
a file. It can save to various image formats. Additionally, you can change the
aspect ratio and the resolution of the screen shot using the "Options"
button to get access to more parameters.


[[Image:Save_picture.png|800px]]
This command can also use the image comment field of some image formats, like PNG or JPEG
{{Caption|The Save picture dialog box after pressing the Extended button}}
to save [[MIBA]] information along with the picture.


<span id="Usage"></span>
==Применение==


# Select the {{MenuCommand|Tools → [[Image:Std_ViewScreenShot.svg|16px]] Save image...}} option from the menu.
==== Image formats ====
# The Save image dialog box opens.
FreeCAD uses the QT built-in image types and some QT plugins in the bin/imageformats directory
# Optionally press the {{Button|Extended}} button to reveal an additional panel in the dialog box. For more information see [[#Options|Options]].
to save pictures. So how many and what formats you can choose depends on your platform.
# Optionally browse to the correct folder.
# Enter a filename and select the file type.
==== Dialog ====
# Press the {{Button|Save}} button to create the image file and close the dialog box.


<span id="Options"></span>
[[Image:Save_picture.png|550px]]
==Опции==


===Image dimensions===


# Select a standard size from the '''Standard sizes''' dropdown list. Or specify the '''Width''' and '''Height''' for a custom size.
===== Image Size =====
# Optionally press an '''Aspect ratio''' button to set the width-to-height ratio of the image. If the '''Width''' input box has the focus the height of the image will change and vice versa.
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.


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


# Select an option from the '''Background''' dropdown list:
===== Image background =====
With this combo box you can choose the background of the picture you make.
#* {{Value|Current}} This option uses the background of the 3D view.
#* {{Value|White}}
* '''Current''' use the current view background (as chosen in the preferences)
#* {{Value|Black}}
* '''White''' creates a plain white background (for e.g. printings)
#* {{Value|Transparent}} Not all image formats support transparency.
* '''Black''' plain black background
# Select an option from the '''Creation method''' dropdown list:
* '''Transparent''' creates a transparent background on image formats which support transparency
#* {{Value|Offscreen (New)}} This is the default method. This method supports [https://en.wikipedia.org/wiki/Multisample_anti-aliasing anti-aliasing]. ''Technical information: The most important classes for this method are Qt's QOffscreenSurface and QOpenGLFramebufferObject.''
#* {{Value|Offscreen (Old)}} This method does not work on many modern Linux systems as it relies on the graphics driver. This method does not support anti-aliasing. ''Technical information: This is a real off-screen rendering method that only uses functions from the Coin3d library.''
#* {{Value|Framebuffer (custom)}} This method supports anti-aliasing. ''Technical information: If anti-aliasing is off, this method reads the image directly from the graphics renderer, else it renders to a framebuffer and gets the image from there. The key part of this method is Qt's QOpenGLFramebufferObject class.''
#* {{Value|Framebuffer (as is)}} This method uses the same techniques as '''Framebuffer (custom)'''. It also supports anti-aliasing but has some limitations related to custom sizes and always uses the current background of the 3D view.


===== Comment =====
===Image 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.


# Select the {{RadioButton|TRUE|Insert MIBA}} option to add [[MIBA]] information to the file. Not all image formats support this.
==== Scripting ====
# Or select the {{RadioButton|TRUE|Insert comment}} option and type a comment in the text field to embed a comment in the file. Not all image formats support this.
It's also possible to save the screen by python:
# Check the {{CheckBox|TRUE|Add watermark}} checkbox to add a watermark. The watermark is placed in the lower left corner of the image and consists of the FreeCAD logo and name above the main FreeCAD URL: [http://www.freecadweb.org www.freecadweb.org].

==Примечания==
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.
* The number of available image file formats may vary depending on your OS.

* Some OpenGL drivers don't allow renderings above a certain maximum size.

Scripting

It is possible to create screenshots with python code.

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

This script saves a series of screenshots of different sizes and from different directions. The camera type, orthographic or perspective, is also 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
