Parent page: Schematic Objects
An image object is a non-electrical drawing primitive. It is essentially a container for an image file that can be imported and placed onto a schematic sheet. The image associated with an image object can either be linked or embedded.
Image objects are available for placement in both Schematic and Schematic Library Editors:
After launching the command, the cursor will change to a cross-hair and you will enter image placement mode. Placement is made by performing the following sequence of actions:
Additional actions that can be performed during placement – while the image's frame is still floating on the cursor, and before its first corner is anchored – are:
This method of editing allows you to select a placed image object directly in the workspace and change its size, shape or location, graphically.
When an image object is selected, the following editing handles are available:
The following methods of non-graphical editing are available:
Dialog page: Graphic
This method of editing uses the Graphic dialog to modify the properties of an image object.
The Graphic dialog can be accessed prior to entering placement mode, from the Schematic – Default Primitives page of the Preferences dialog. This allows the default properties for the image object to be changed, which will be applied when placing subsequent image objects.
During placement, the dialog can be accessed by pressing the Tab key.
After placement, the dialog can be accessed in one of the following ways:
An Inspector panel enables the designer to interrogate and edit the properties of one or more design objects in the active document. Used in conjunction with appropriate filtering - by using the applicable Filter panel, or the Find Similar Objects dialog - the panel can be used to make changes to multiple objects of the same kind, from one convenient location.
A List panel allows the designer to display design objects from one or more documents in tabular format, enabling quick inspection and modification of object attributes. Used in conjunction with appropriate filtering - by using the applicable Filter panel, or the Find Similar Objects dialog - it enables the display of just those objects falling under the scope of the active filter – allowing the designer to target and edit multiple design objects with greater accuracy and efficiency.
The majority of supported image formats - including bmp, png, jpg, and tiff - are Raster-based. Simply put, they are created (or composed) graphically, of a fixed series of dots. And while all of these image formats render adequately, their attraction diminishes when the image is scaled. Zoom right in to an image in one of these formats and the 'blocky' or 'pixelated' nature of the image's dot composition soon becomes apparent. The solution to this, is to use a Vector-based image format. Vector images are composed of graphical shapes rather than dots, which are preserved upon scaling.
The Schematic Editor supports vector-based graphics in the form of WMF (Windows Meta File) and SVG (Scalable Vector Graphics) formats.
