(GLUE COMPOUND)

Glue selected objects and make them a COMPOUND object. This is useful to move or copy some objects together at the same time. It is also possible to scale part of a figure by scaling a COMPOUND object after making part of the figure COMPOUND.

Clicking on an object with mouse button 1 (`tag object') will tag the object. Clicking one corner of a rectangular region with mouse button 2 (`tag region') and then clicking mouse button 2 (`final corner') again at the opposite corner of the rectangular region will tag all objects inside the region. After tagging all objects to be glued into a COMPOUND object, clicking mouse button 3 (`compound tagged') will glue those objects and make them a COMPOUND object.

If an already tagged object is selected by mouse button 1 or mouse button 2, that object will be untagged. If you want to remove all tags, change the mode temporarily to any other mode (e.g. "move object") except BREAK COMPOUND.

The COMPOUND object may be separated into component objects by BREAK COMPOUND.

(BREAK COMPOUND)

Break a COMPOUND object into separate component objects.

Clicking a COMPOUND object with mouse button 1 (`break compound') will break the COMPOUND into separate component objects. Clicking with mouse button 2 (`break and tag') will also achieve the same effect, but it will tag those component objects for re-gluing with GLUE COMPOUND again.

If you want to edit component objects without breaking the COMPOUND object, you may open the COMPOUND object temporarily using OPEN COMPOUND.

(OPEN COMPOUND)

Open a compound object temporarily for editing the component objects.

Clicking a COMPOUND object with mouse button 1 (`open compound') will open the COMPOUND object, and then the component objects may be edited. All other objects which were not in the COMPOUND object will become invisible temporarily, but they will reappear after all COMPOUND objects are closed.

A popup panel with two buttons to close the COMPOUND objects (Close This Compound and Close All Compounds) will appear when a COMPOUND object is opened, and the open COMPOUND may be closed again using those buttons. Clicking Close This Compound will close the COMPOUND object last opened, and clicking Close All Compounds will close all nested, opened COMPOUND objects.

If you want to break a COMPOUND object into component objects, use BREAK COMPOUND.

If the File/Save is attempted while a compound is open, xfig will ask if you want to save only the open COMPOUND object (Save Part) or the whole figure (Save All).

Note: If you open a COMPOUND object, delete an object in that COMPOUND object, close the COMPOUND object and Undo the delete operation, the object you deleted will reappear but it will outside of the COMPOUND object. Conversely, if you delete an object from the canvas, open a compound then undo the delete of the original object, it will now be part of the open compound. In this way you may add or remove selected objects from a COMPOUND.

(SCALE OBJECT)

Scale object.

Clicking any corner of BOX, ARC-BOX, or COMPOUND object with mouse button 1 (`scale box') and dragging the mouse will start scaling the object proportionally to its horizontal/vertical ratio. Clicking any edge of that object with mouse button 1 (`scale box') will start scaling the object only in one dimension (width or height). The scaling operation is finished by clicking mouse button 1 (`new position') again.

Clicking on an object with mouse button 2 (`scale about center') will scale the object proportionally about its center. The scaling operation is finished by clicking mouse button 2 (`new position') again.

In any case, The scaling operation may be canceled by clicking mouse button 3 (`cancel').

It is not possible to scale TEXT objects directly with this function. To scale TEXT objects, use EDIT OBJECT or UPDATE and change the size of the text (see TEXT SIZE). However, if a COMPOUND object that includes TEXT objects is scaled, the TEXT objects will also be scaled if the Rigid flag is not set.

You may use also MOVE POINT if you want to scale an object such as a BOX without keeping its horizontal/vertical ratio.

(ALIGN)

Align objects. How objects are aligned is set by VERTICAL ALIGN and HORIZONTAL ALIGN.

Clicking on a COMPOUND object with mouse button 1 (`align compound') will align objects within in the COMPOUND object. Clicking mouse button 2 (`align canvas') anywhere on the canvas will align all objects to the canvas.

(MOVE POINT)

Move a point of an object.

Select the point to be moved by clicking the point with mouse button 1 (`move point'), and finish the move by click mouse button 1 (`new position') again after moving mouse to the new point. If you want to restrict the move to horizontal or vertical, use mouse button 2 (`horiz/vert move') instead of mouse button 1. The operation may be canceled by clicking mouse button 3 (`cancel') in either case.

This may not be used for TEXT objects. For BOX, ARC-BOX, and COMPOUND objects, not only the selected point but the edges connected to the point will be moved. The object created by REGULAR POLYGON is an ordinary POLYGON object, and only the selected point will be moved.

Points may also be added or deleted. If you want to move entire object, use MOVE instead.

(ADD POINTS)

Add a new point to a POLYLINE, POLYGON, or SPLINE object.

Clicking mouse button 1 (`break/add here') between two points of an object will add a new point at that location, and the point will move following mouse cursor. The operation is finished by clicking mouse button 1 (`place new point') again.

It is not possible to add a point to BOX or ARC-BOX objects. The object created by REGULAR POLYGON is an ordinary POLYGON object, and it is possible to add new points anywhere in it.

Points may also be moved or deleted.

(DELETE POINTS)

Delete point from POLYLINE, POLYGON, or SPLINE object.

Clicking a point to be deleted with mouse button 1 (`delete point') will delete the point, and the points on either side of the point will connected directly.

It is not possible to delete points from a BOX or ARC-BOX object. The object created by REGULAR POLYGON is ordinary POLYGON object, and it is possible to delete points from it.

Points may also be moved or added.

(MOVE)

Move object.

Select the object to be moved by clicking the object with mouse button 1 (`move object'), and finish the move operation by clicking mouse button 1 (`place object') again at the new position. If you want to restrict the movement to horizontal or vertical, use mouse button 2 (`horiz/vert move') instead of mouse button 1. The operation may be canceled by clicking mouse button 3 (`cancel') in either case.

If you want to move several objects at one time, you may put them into a COMPOUND object using GLUE COMPOUND.

By setting SMART-LINKS MODE, it is possible to move the endpoints of lines which touch the object as you move the object itself. This only works with POLYLINES (not splines) touching a BOX or ARC-BOX.

Objects may also be copied or deleted. If you want to move a point of the object, use MOVE POINT instead.

(COPY)

Copy object.

Select the object to be copied by clicking the object with mouse button 1 (`copy object'), and finish the copy operation by clicking mouse button 1 (`place object') again at the position to place the copy. If you want to restrict the movement to horizontal or vertical, use mouse button 2 (`horiz/vert copy') instead of mouse button 1. The operation may be canceled by clicking mouse button 2 (`cancel') in either case.

If you want to copy several objects at the same time, you may put them a COMPOUND object using GLUE COMPOUND.

By setting SMART-LINKS MODE, it is possible to copy the lines which touch the object as you move the object itself. This only works with POLYLINES (not splines) touching a BOX or ARC-BOX.

It is also possible to make many copies in this mode, using ARRAY PLACEMENT. To do this, first set the number of copies to be created by setting NUMER OF X COPIES and NUMER OF Y COPIES. Then select the object to be copied by clicking the object with mouse button 1 (`copy object'), and specify the direction and distance to place the copies by clicking mouse button 2 (`array placement') after moving the mouse.

Clicking an object with mouse button 3 (`copy to cut buf') will copy the object to the xfig cut buffer. The object copied into the xfig cut buffer may be inserted into the figure on the canvas using PASTE. This allows you to copy part of a figure to another figure. Any object in the xfig cut buffer will be overwritten when the new object is copied into the xfig cut buffer. To copy multiple objects into the xfig cut buffer, you must first put them into a COMPOUND object using GLUE COMPOUND.

Objects may also be moved or deleted.

(DELETE)

Delete object.

Clicking an object with mouse button 1 (`delete object') will remove the object. It is also possible to remove objects in a rectangular region by clicking mouse button 2 (`delete region') at one corner of the region and then again (`final corner') again at the opposite corner.

Clicking an object with mouse button 3 (`del to cut buf') will remove the object from the canvas and move it to the xfig cut buffer. The object moved into the xfig cut buffer may be inserted into the figure on the canvas using PASTE later. See also COPY.

If you want to delete all objects from the canvas to make a new figure, you may use New.

(UPDATE)

Update the attributes (such as line width or colors) of object with the current settings in the Indicator Panel. Conversely, it is also possible to copy the attributes of an object to the indicator panel.

Clicking an object with mouse button 1 (`update object') will apply the current settings of the indicator buttons selected for UPDATE to the object. If a COMPOUND object is clicked with mouse button 1 (`update object'), the attributes of all the objects in the COMPOUND object will be updated.

Clicking an object (except a COMPOUND object) with mouse button 2 (`update settings') will copy the attributes of the object to the indicator buttons which are selected for UPDATE. This allows you to copy attributes from one object to another object.

In UPDATE mode, a small toggle button appears in the upper-right corner of each indicator button, and only the indicator buttons whose toggle button is set ON will be used for update. Clicking the toggle button at the upper-right corner of an indicator button will toggle the button ON/OFF. It is also possible to select, unselect, or toggle all indicator buttons, using Update Control buttons at the left side of the indicator panel.

The attributes of objects may also be modified using EDIT OBJECT. Some attributes can't be modified by UPDATE but may be modified by EDIT OBJECT.

(EDIT OBJECT)

Edit various attributes (such as line width or colors) of object.

Clicking an object with mouse button 1 (`edit object') will popup the Edit Panel to edit the attributes. The items in the panel depend on the object being edited. See Edit Panel for more information.

Clicking a control point of a SPLINE object with mouse button 3 (`edit point') will popup EDIT POINT panel to modify the shape factor of the spline curve.

The attributes of objects may also be modified using UPDATE, but some attributes can't modified with UPDATE.

(FLIP VERTICALLY/HORIZONTALLY)

Flip object vertically or horizontally. It is also possible to make a copy of the object flipped vertically or horizontally.

Clicking the object with mouse button 1 (`flip') will flip the object vertically/horizontally about that point. Clicking the object with mouse button 2 (`copy & flip') will make copy of the object flipped vertically/horizontally about that point, leaving original object as it was.

It is also possible to set the anchor point about which the object will be flipped, by clicking mouse button 3 (`set anchor') at the point. A crosshair (+) indicates the anchor point on the canvas. The anchor point may be removed by clicking mouse button 3 (`set anchor') again.

To rotate an object, use ROTATE.

(ROTATE)

Rotate object by specified angle.

Clicking an object with mouse button 1 (`rotate object') will rotate the object to clockwise or counter-clockwise by the angle specified by ROTATION ANGLE about the point that is clicked.

It is also possible to make many copies in this mode, using COPY & ROTATE. Clicking object with mouse button 2 (`copy & rotate') may make many copies rotated by the angle specified by the ROTATION ANGLE. The number of copies to be created may be set by NUMBER OF COPIES.

As in FLIP VERTICALLY/HORIZONTALLY, it is possible to set the anchor point about which the object will be rotated, by clicking mouse button 3 (`set anchor').

BOX, ARC-BOX and PICTURE objects, and COMPOUND objects containing any of those objects may only be rotated by multiples of 90 degrees. To flip object vertically or horizontally, use FLIP VERTICALLY/HORIZONTALLY.

(SPLINE <-> LINE / BOX <-> ARC-BOX)

Convert object type.

Clicking an object with mouse button 1 (`spline <-> line') will perform a conversion thus:

polyline --> open approximated spline --> open interpolated spline --> polyline
polygon --> closed approximated spline --> closed interpolated spline --> polygon
box --> arc-box --> box

Clicking an object with mouse button 3 (`open <-> close') will perform a conversion thus:

polyline <-> polygon
open approximated spline <-> closed approximated spline
open interpolated spline <-> closed interpolated spline

Finer control is possible for spline curves. See EDIT POINT and About Spline Curves for more information.

(ADD/DELETE ARROWS)

Add/delete arrow head to/from POLYLINE, OPEN SPLINE, or OPEN ARC.

Clicking the end point of object with mouse button 1 (`add arrow') will add an arrow head to that end. Clicking an arrow head with mouse button 2 (`delete arrow') will remove the arrow head.

The shape of the arrow head may be set by ARROW TYPE. The size of arrow head may be set by ARROW SIZE. It is also possible to automatically create arrow heads when creating new objects by setting ARROW MODE.

Selecting Objects

Most objects may also be selected by clicking on the line connecting corner markers, but it may have a different meaning in some editing modes. For example in the SCALE OBJECT mode, clicking on a corner marker will scale the object proportionally to its horizontal/vertical ratio, but clicking on a line connecting corner markers (edge of the rectangle) will scale the object only in that direction (i.e. horizontally or vertically).

If POINT POSITION is set to other than Any, objects which are not on the virtual grid may not be be selected.

When object corners or edges are coincident, clicking on the object may not select the desired object but the other object instead. In this case, the desired object may be selected with following operations:

1. Press (and hold) the SHIFT key and click on the object to be selected.
2. If the corner marker of the other object is highlighted, keep the SHIFT key down and click the object again.
3. When corner marker of the desired object is highlighted, release the SHIFT key and click the object again.

PICTURE object

Screen Capture

This is used to capture an image displayed on the screen. After clicking Screen Capture button, you can perform one of following actions:

1. click mouse button 1 on any window to capture the whole window
2. click mouse button 1 on the root window (background of the screen) to capture the whole screen
3. click mouse button 2 on one corner of a rectangle on the screen, drag the mouse to the other corner and click mouse button 2 again, to capture image in the rectangle
4. click mouse button 3 to cancel capture operation

During the capture operation, xfig unmaps all its windows from the screen. Those windows reappear on the screen when completing or cancelling the capture. The captured image will be displayed on the canvas in the picture object area. During the capture, the xfig window(s) will be hidden (unmapped). The captured image will be stored in a file such as figure1_828065129.gif, which includes the current figure name and the time in seconds since 00:00:00 GMT, Jan 1, 1970. The file format will be GIF format or PCX format, and will be indicated in the picture type area.

Edit Image

Clicking this button will invoke an external bitmap editor (the default is xv) to edit the image. xfig unmaps all its windows from the screen when it invokes the bitmap editor, but those windows reappear on the screen again when you exit the bitmap editor. Edit Image will invoke xv by default, but you can change it to invoke your favorite bitmap editor (xpaint, for example) with the resource Fig.image_editor or command-line argument -image_editor.
