Picture

The properties of a picture are:

Picture size

Width	Specifies the width of the picture.
Height	Specifies the height of the picture.

Background

Transparent	Makes the background transparent.
Filled	Makes the background fully coloured
Colour	Specifies the background colour for the Filled option.

Clipping box

Use

Switches on or off the clipping box.

For more information about this SCIA Engineer feature see chapter Advanced tools > Clipping box.

Edit

Provides for editing of the clipping box.

Default box

Sets the default clipping box.

On scale

Use	If ON, tells the program to make the printing in required scale.
Scale	If the option above is ON, the user may specify the scale for the printing.

Advanced

Rotation	Specifies the rotation angle of the picture.
OpenGL	Selects the required rendering mode for the picture.
Hidden lines	Specifies the mode that is used to draw hidden lines and surfaces.
Perspective	Switches on and off the perspective.
Lock view	Locks the view so that it is not possible to adjust the view direction. It is intended to prevent an accidental maladjustment once the required view direction has been properly adjusted.
Line pattern	Defines the pattern for dashed lines in the picture.

OpenGL

If the option Display style in the Page setup is set to OpenGL, this option is unavailable because the whole graphic output drawing is rendered.

If the option Display style of the Page setup is set to Windows, this option allows the user to set required rendering mode for the particular picture.

This option is present here to allow all users to use rendering in their graphical output regardless of the particular type of graphical device that they are using. The unlucky fact is that some of printing devices may have problems with rendered pictures. The main reason is the insufficiency of memory for printing if the Display style in the Page setup is adjusted to OpenGL In order to overcome possible difficulties with some printing devices, SCIA Engineer offer a unique solution. The rendered picture is created in the program using only such amount of memory that the user specifies. Such "memory-limited" picture is then stretched to the required size and sent to the printing device.

The possible options for the rendering are:

Photo	Suitable for fully rendered drawings of details.
Dark lines	Suitable for drawings in dark lines on light background.
Light lines	Suitable for drawings in light lines on dark background.

More information about these options can be found in chapter Graphic output > Items of graphic output drawing > Selecting the suitable stretch mode.

Each of the above mentioned optioned allows the user to specify the size of the memory for rendering made in SCIA Engineer.

0.2 Mb	The picture occupies 0.2 Mb of memory.
0.9 Mb	The picture occupies 0.9 Mb of memory.
1.44 Mb	The picture occupies 1.44 Mb of memory.
2.4 Mb	The picture occupies 2.4 Mb of memory. If this picture is stretched to fit an A4 format, the drawing can still be considered of a rather good quality.
12 Mb	The picture occupies 12 Mb of memory. If this picture is stretched to fit an A0 format, the drawing is of a good quality.

The procedure for the editing of picture properties is given in chapter Adjusting the picture properties.
