IWxStyle.PictureProportional

Syntax

PictureProportional: Boolean;

PictureProportional: boolean;

Description

The PictureProportional property enables the user to lock aspect ratio of an image when resizing an object. If the property is set to True, the aspect ratio is locked, if it is set to False, it is not.       

The default property value is False.

Example

Executing the example requires that repository contains a workspace with the IWSTYLE identifier containing shape. It is also required to have the ConnectedCPs.gif image.

Add links to the Andy, Drawing, Metabase system assemblies.

Sub UserProc;
Var
    mb: IMetabase;
    ws: IWxWorkspace;
    Shape: IWxShape;
    style: IWxStyle;
Begin
    // Get workspace for edit
    mb := MetabaseClass.Active;
    ws := mb.ItemById("IWSTYLE").Edit As IWxWorkspace;
    Shape := ws.Shapes.Item(0);
    Shape.Picture := GxImage.FromFile("C:\ConnectedCPs.gif");
    Style := Shape.Style;
    Style.PictureProportional := True;
    (ws As IMetabaseObject).Save;
End Sub UserProc;
Imports Prognoz.Platform.Interop.Andy;
Imports Prognoz.Platform.Interop.Drawing;
 
Public Shared Sub Main(Params: StartParams);
Var
    mb: Imetabase;
    ws: IWxWorkspace;
    Shape: IWxShape;
    style: IWxStyle;
    Img: GxImage;
    Color: GxColorClassClass = New GxColorClassClass();
Begin
    // Get workspace for editing
    mb := Params.Metabase;
    ws := mb.ItemById["IWSTYLE"].Edit() As IWxWorkspace;
    Shape := ws.Shapes.Item[0];
    Img := New GxImageClass_2();
    Img.CreateFromFile("C:\ConnectedCPs.gif");
    Shape.Picture := Img;
    Style := Shape.Style;
    Style.PictureProportional := True;
    // Save changes
    (ws As IMetabaseObject).Save();
End Sub;

After executing the example image size is scaled with the aspect ratio locked when resizing an object.
