Placement

After launching the command, the cursor will change to a cross-hair, and you will enter graphic placement mode. Placement is made by performing the following sequence of actions:

1. Position the cursor then click or press Enter to anchor the first corner of the graphic's frame in which the graphic itself will reside.
2. A dialog will open in which you can browse and select the required graphic. Select the file you want to insert then press Open.
3. Move the cursor to adjust the frame size then click or press Enter to complete graphic placement.
4. Continue placing further graphic objects or right-click or press Esc to exit placement mode.

During placement, before the graphic frame's second corner is anchored, press the Tab key to pause the placement and access the Image mode of the Properties panel from where its properties can be changed on the fly. Click the design space pause button overlay ( ) to resume placement.

Graphical Editing

This method of editing allows you to select a placed image object directly in the design space and change its size, shape or location graphically.

When an image object is selected, the following editing handles are available:

A selected Image

• Click and drag A to simultaneously resize the image frame in the vertical and horizontal directions.
• Click and drag B to resize the image frame in the vertical and horizontal directions separately (provided the X:Y Ratio 1:1 option in the Properties panel is disabled).
• Click anywhere on the image away from editing handles, then drag it to reposition it. Press the Alt key to constrain the direction of movement to the horizontal or vertical axis depending on the initial direction of movement. While dragging, the image can be rotated (Spacebar/Shift+Spacebar) or mirrored (X or Y keys to mirror along the X-axis or Y-axis).

Using Vector Graphics

The majority of supported image formats are Raster-based. Simply put, they are graphically created (or composed) of a fixed series of dots. While all of these image formats render adequately, their attraction diminishes when the image is scaled. Zoom 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.

An example image on a schematic. A PNG version above with its SVG incarnation below. When zoomed in, the quality of the latter becomes appreciatively noticeable.

Notes

• The following image formats are supported: .bmp, .dcx, .dib, .emf, .jpg, .pcx, .png, .rle, .svg, and .wmf.
• To retain the image's original aspect ratio, ensure that the X:Y Ratio 1:1 option is enabled in the Properties panel. When this option is enabled, the image will be scaled to fit optimally into the frame size specified while maintaining the original aspect ratio of the image. If the option is disabled, the image is stretched to fit exactly into the drawn frame size.

• A copy of a placed image will only be stored inside the schematic sheet if the corresponding Embedded option is enabled in the Properties panel. If this option is disabled, only a link to the image file will be stored. Care should be taken when using linked images – if the location of the image changes, you will need to update the link accordingly using the File Name field in the Properties panel.

  Alternatively, you can define a relative path to the image by editing the File Name field, for example:

  • \company_logo.png - the company_logo image is located in the same folder as the schematic/schematic library file.
  • \img\company_logo.png - the company_logo image is located in the img folder which, in turn, is located in the same folder as the schematic/schematic library file.
  • ..\company_logo.png - the company_logo image is located in the folder one level up from the folder in which the schematic/schematic library file is located.
  • ..\..\company_logo.png - the company_logo image is located in the folder two levels up from the folder in which the schematic/schematic library file is located.

Location

• (X/Y)
  • X (first field) – the current X (horizontal) coordinate of the reference point of the object, relative to the current design space origin. Edit to change the X position of the object. The value can be entered in either metric or imperial; include the units when entering a value whose units are not the current default.
  • Y (second field) – the current Y (vertical) coordinate of the reference point of the object, relative to the current origin. Edit to change the Y position of the object. The value can be entered in either metric or imperial; include the units when entering a value whose units are not the current default.

Properties

• File Name – the name of the graphic file. Click  to open a dialog to search for and select an image.

• Embedded – click to embed the graphic.

  To have the image render correctly when viewing a schematic in an Altium 365 Viewer (e.g., the Web Viewer or the standalone Altium 365 Viewer), this option must be enabled for the image.
• Width – the width of the graphic.
• Height – the height of the graphic. 
• X:Y Ratio 1:1 – enable to make the X and Y ratio 1 to 1.
• Border – enable the box to show a border. Use the drop-down to select the default from the available choices.

A rectangle is a non-electrical drawing primitive. It is a graphic element that can be placed on a schematic sheet and can be filled or unfilled.

Availability

Rectangles are available for placement in both Schematic and Schematic Library Editors:

• Schematic Editor - the following commands are available:
  • Choose Place » Drawing Tools » Rectangle from the main menus.
  • Click the  button in the graphic objects drop-down on the Active Bar located at the top of the design space. (Click and hold an Active Bar button to access other related commands. Once a command has been used, it will become the top-most item on that section of the Active Bar.)
  • Right-click in the design space then choose Place » Drawing Tools » Rectangle from the context menu.
  • Click the   button on the Utility Tools drop-down () of the Utilities toolbar.
• Schematic Library Editor - the following commands are available:
  • Choose Place » Rectangle from the main menus.
  • Click the Rectangle button ( ) in the graphic objects drop-down on the Active Bar menu located at the top of the design space. (Click and hold an Active Bar button to access other related commands. Once a command has been used, it will become the top-most item on that section of the Active Bar.)
  • Right-click in the design space then choose Place » Rectangle from the context menu.
  • Click the   button on the Utility Tools drop-down ( ) of the Utilities toolbar.​

Placement

After launching the command, the cursor will change to a cross-hair, and you will enter rectangle placement mode. Placement is made by performing the following sequence of actions:

1. Click or press Enter to anchor the first corner of the rectangle.
2. Move the cursor to adjust the size of the rectangle then click or press Enter to complete placement.
3. Continue placing further rectangles or right-click or press Esc to exit placement mode.

Additional actions that can be performed during placement while the rectangle is still floating on the cursor and before its first corner is anchored are:

• Press the Tab key to pause the placement and access the Rectangle mode of the Properties panel from where its properties can be changed on the fly. Click the design space pause button overlay ( ) to resume placement.
• Press the Alt key to constrain the direction of movement to the horizontal or vertical axis depending on the initial direction of movement. 
• Press the Spacebar to rotate the rectangle counterclockwise or Shift+Spacebar for clockwise rotation. Rotation is in increments of 90°.

Graphical Editing

This method of editing allows you to select a placed rectangle object directly in the design space and change its size, shape or location graphically.

When a rectangle object is selected, the following editing handles are available:

A selected Rectangle

• Click and drag A to simultaneously resize the rectangle in the vertical and horizontal directions.
• Click and drag B to resize the rectangle in the vertical and horizontal directions separately.
• Click anywhere on the rectangle away from editing handles, then drag it to reposition it. While dragging, the rectangle can be rotated (Spacebar/Shift+Spacebar) or mirrored (X or Y keys to mirror along the X-axis or Y-axis).

Location

• (X/Y)
  • X (first field) - the current X (horizontal) coordinate of the reference point of the object, relative to the current design space origin. Edit to change the X position of the object. The value can be entered in either metric or imperial; include the units when entering a value whose units are not the current default. 
  • Y (second field) - The current Y (vertical) coordinate of the reference point of the object, relative to the current origin. Edit to change the Y position of the object. The value can be entered in either metric or imperial; include the units when entering a value whose units are not the current default. 

Properties

• Width - enter the width of the object, which may be edited.
• Height - enter the height of the object, which may be edited.
• Border - use the drop-down to select the default from the available choices. Click on the color box to access a drop-down from which you can select the default border color.
• Line Style - use the drop-down to select the line style of the rectangle's border.
• Fill Color - check to enable fills. Click on the color box to access a drop-down from which you can select the default fill color.
• Transparent - check to make the primitive transparent.

A placed Round Rectangle

Summary

A round rectangle is a non-electrical drawing primitive. It is essentially a rectangle object with rounded corners that can be placed on a schematic sheet and can be filled or unfilled.

Availability

Round rectangles are available for placement in both Schematic and Schematic Library Editors:

• Schematic Editor - the following commands are available:
  • Choose Place » Drawing Tools » Round Rectangle from the main menus.
  • Click the Round Rectangle button () in the graphic objects drop-down on the Active Bar located at the top of the design space. (Click and hold an Active Bar button to access other related commands. Once a command has been used, it will become the top-most item on that section of the Active Bar.)
  • Right-click in the design space then choose Place » Drawing Tools » Round Rectangle from the context menu.
  • Click the  button on the Utility Tools drop-down () of the Utilities toolbar.
• Schematic Library Editor - the following commands are available:
  • Choose Place » Round Rectangle from the main menus.
  • Click the Round Rectangle button () in the graphic objects drop-down on the Active Bar menu located at the top of the design space. (Click and hold an Active Bar button to access other related commands. Once a command has been used, it will become the top-most item on that section of the Active Bar.)
  • Right-click in the design space then choose Place » Round Rectangle from the context menu.
  • Click the  button on the Utility Tools drop-down () of the Utilities toolbar.

Placement

After launching the command, the cursor will change to a cross-hair, and you will enter round rectangle placement mode. Placement is made by performing the following sequence of actions:

1. Click or press Enter to anchor the first corner of the round rectangle.
2. Move the cursor to adjust the size of the round rectangle then click or press Enter to complete placement.
3. Continue placing further round rectangles, or right-click, or press Esc to exit placement mode.

Additional actions that can be performed during placement while the round rectangle is still floating on the cursor and before its first corner is anchored are:

• Press the Tab key to pause the placement and access the Round Rectangle mode of the Properties panel from where its properties can be changed on the fly. Click the design space pause button overlay ( ) to resume placement.
• Press the Alt key to constrain the direction of movement to the horizontal or vertical axis depending on the initial direction of movement.
• Press the Spacebar to rotate the round rectangle counterclockwise or Shift+Spacebar for clockwise rotation. Rotation is in increments of 90°.
• Press the X or Y keys to mirror the round rectangle along the X-axis or Y-axis.

Graphical Editing

This method of editing allows you to select a placed round rectangle object directly in the design space and change its size, shape or location graphically.

When a rounded rectangle object is selected, the following editing handles are available:

A selected Round Rectangle

• Click and drag A to simultaneously resize the round rectangle in the vertical and horizontal directions.
• Click and drag B to resize the round rectangle in the vertical and horizontal directions separately.
• Click and drag C to change the curvature of the corners. This affects all corners equally regardless of which editing handle is chosen.
• Click anywhere on the round rectangle away from the editing handles then drag to reposition it. While dragging, the round rectangle can be rotated (Spacebar/Shift+Spacebar) or mirrored (X or Y keys to mirror along the X-axis or Y-axis).

Location

• (X/Y) - the X (horizontal) coordinate and Y (vertical) coordinate of the object. 

Properties

• Width - can be edited.
• Height - can be edited.
• Corner X-Radius - the curvature of the rectangle's corners in the horizontal plane, which may be edited.
• Corner Y-Radius - the curvature of the rectangle's corners in the vertical plane, which may be edited.
• Border - ​use the drop-down to select the default border width from the available choices. Click on the color box to change the color.
