The toolbar located on the left side of the window is used to create objects using your browser, remotely over the internet. Four type of objects can be created ( Polygons, Lines, Points and Text ). Each object will belong to an existing Class and Subclass. The way it will appear depends on the display settings already made in GeoConcept.
Creating polygons:
To create a new polygon object, proceed as follows: |
|
Creating Lines:
• Enable the Line creation tool with a single click. Then proceed exactly as above, except there is no automatic linking of last to the first
point.
Point object creation: To create a point object, proceed as follows:
•Enable the Point creation tool for the object being created with a single click. The mouse cursor switches into capture mode and turns into a
cross ( ); at the top left of the map, the mouse cursor coordinates are automatically displayed.
•Click once on the map to create the point at the required position. This creates and validates the new point object;
Creating text objects:
• Enable the Text creation tool with a single click. The mouse cursor switches into capture mode and turns into a cross ( ) •Click once on the
map to create the text object at the required position. This creates and validates the new text object.To enter text into this object, you must
use the EDIT Attribute data feature.
The text object has already been selected (check that there is an outline box). Open the Attribute data table for editing. Go to the NAME field.
Type in whatever you want to appear on the map.
Editing Tools:
This button handles transformation functions (movement, rotation), field editing, and object colouring and deletion.
Modifying geometry:
This button is used to modify existing object geometry. Any object on the map currently visible that is selectable and unprotected
can be modified. To modify the geometry of an existing object, proceed as follows : •select the object(s) requiring editing using any
available selection functions (see also Selecting objects); •activate the geometry editing tool with a single click. When moving this tool in
the map, selected objects are displayed in a frame, and their geometry is greyed out (however, points making up polygon or line geometry are
shown) ; •modify the geometry of the selection :
•Move an existing point by clicking and dragging on it (the old plot remains displayed so long as the modification made to the geometry has not
been validated);
•Add an intermediary point: to do this, point at an existing point and then press on the Insert key on the keyboard ; a new point will be added
to the object geometry midway between the first point pointed at and the following point;
•Delete an existing point by pointing at it with the mouse and pressing on either delete key on the keyboard (backspace or Delete).
Moving objects:
Any visible object can be moved, so long as it is selectable, and unprotected.
•First Select the object or objects to be moved using any available selection function (see also Selecting objects);
•Activate the object displacement tool with a single click ;
•Point the mouse cursor at the object to be moved ; its outline plus the rectangular space it occupies are displayed in black; •Move the
object with a click and drag of the mouse; the value of the translation vector displays at the top left of the map (delta-X, delta-Y) : the tool’s
transformation outline is the only thing that moves, the object only moves following validation of the displacement ;
•Validate the object’s displacement as follows : •either type Enter at the keyboard. •or double-click on the displaced object.
Object rotation:
Any object that is visible, selectable, and unprotected can be rotated.
•Select the object or objects to rotate using any available selection functions (see also Selecting objects) ;
•Activate the object rotation tool with a single click ;
•Point the mouse cursor at the object to be rotated; its outline plus the rectangular space it occupies appear in black, and four little black
circles display at the four corners of the rectangular space; pivot the object using a click and drag mouse action on one of the four snap points
for the rotation (the little black circles); the rotation angle value in degrees displays at the top left of the map; the tool’s transformation
outline is the only thing that pivots until the rotation is validated, at which point the object itself is rotated;
•Validate the object rotation as follows : •either type Enter at the keyboard. •or double-click on the rotated object.
Re-sizing objects:
Any polygon or line that is visible, selectable, and unprotected can be re-sized.
•Select the object or objects to re-size using any available selection function (see also Selecting objects) ;
•Activate the re-sizing tool with a single click ;
•Point the mouse cursor at the object to be re-sized; its outline plus the rectangular space it occupies are displayed in black, and four little
black squares display at the four corners of this rectangular template;
•Re-size the object: click and drag with the mouse on one of the four little squares to re-size the object; the enlargement factor displays at
the top left of the map (the first number being the factor in X and the second being the factor in Y) ; the tool’s transformation outline is the
only thing to be re-sized until it is validated ; The SHIFT key on the keyboard can be held down during re-sizing so as to apply the same
transformation factor in X and in Y.
•Validate the object re-sizing as follows : •either type Enter at the keyboard •or double-click on the re-sized object.
Editing fields in the Attribute Data Base
Any field that is visible, selectable, and unprotected, can be edited. Click to enable field editing, and proceed as follows : •Select
the objects to be edited using any available selection functions (see also Selecting objects) ;
•Activate the editing tool by clicking on it;
•Point the mouse cursor at the object to be edited; its outline plus that of the rectangular space it occupies appear in black, and an information
form icon appears to the right of the rectangular template;
•Open the object’s information form by clicking once with the mouse on this icon (to the right of the template);
•Edit the fields in the form, clicking on each one in turn to access it. Only Integer, Real, Character, Memo and Hypertext link fields can be
edited in the information form. The other fields can only be viewed. Use the Tab key to move from one field to the next.
•Validate the editing session by clicking on Validate, or •Click on Cancel to abort the editing session.
[Each object’s editable form-window appears systematically in the lower right-hand corner of the object. For this reason, it is best to avoid trying to edit the object form for objects located in the lower right-hand side of the map window. If necessary, move the objects to the North-west of the main map window using the displacement tool (see also Navigation functions).]
Colouring objects:
Any object that is visible, selectable, and unprotected, can be coloured.
•Select the object or objects to be coloured using any available selection functions (see also Selecting objects) ;
•Activate the colouring tool with a single click;
•Point the mouse cursor at the object to be coloured ; its outline plus that of the rectangular space it occupies appear in black and a
colour palette icon appears to the right of this rectangular template;
•Open the Appearance window for the object by clicking on the palette icon to the right of the objects’s rectangular template; •Set
the appearance parameters, clicking on each in turn; •validate the appearance modification button for the object by clicking on Validate, or •cancel
all the modifications made to date by clicking on Cancel.
Colouring polygons:
The Appearance window offers to define in turn, and with a long mouse-click:
•the Colour of the polygon’s fill pattern ; use a long click to access the 256-colour palette;
•the polygon’s Background fill colour as a function of the pattern chosen (obviously this does not apply if the pattern chosen is empty or
solid) ; the long click accesses the 256-colour palette;
•the Fill pattern for the polygon ; the long click accesses a list of 120 presaved patterns;
•the Line thickness for the polygon outline; a long click accesses a list of 10 thicknesses plus one null thickness ;
•the Line colour for the polygon outline ; a long click accesses the 256-colour palette.
Colouring lines:
The Appearance window offers to define in turn, and with a long mouse-click :
•the line’s Outer line colour; a long click accesses the 256-colour palette;
•the line’s Outer line thickness ; a long click accesses a list of 10 thicknesses plus one null thickness;
•the line’s Inner line colour; a long click accesses the 256-colour palette;
•the line’s Inner line thickness; a long click accesses a list of 10 thicknesses plus one null thickness ;
Colouring point objects:
The Appearance window offers to define in turn
•the point object’s symbol colour; a long click opens the 256-colour palette;
•the point object’s symbol size; the size is expressed in pixels;
•the Image style: that is, the way the image is displayed if the point is associated to an image. The image has a constant size as a function of
the scale if the fixed value is chosen; if the proportional size is chosen, the image is proportioned as a function of scale;
•the Symbol family ; the choice is from a list of symbol families;
•the Symbol name ; a different symbol can be chosen in a selected family.
Setting and Colouring text objects:
The Appearance window offers to define in turn:
•the text Colour; a long click opens the 256-colour palette;
•the Font name; type in a font name to change the character font; The font specified must, of course, be installed on the server. •The text
Size in pixels; •By choosing True or False in each case, you can make the text Bold, Highlighted, Italic, Crossed Out or Framed.
Multiple-function object editing:
Click here to access all the functions described above in one go. It is then possible to : •move objects ; •re-size objects; •rotate
objects; manipulate objects’ axis symmetry ; •modify fields in the object information form; •colour objects.
Deleting objects:Any object that is visible, selectable, and unprotected, can be deleted in one of two ways :
Deleting with the mouse -
•select the object or objects to delete using any available selection functions (see also Selecting objects);
•activate the object deletion tool with a single click; •click on each object to delete it.
When deleting objects one by one, no prompt for confirmation is displayed. Deletion cannot be reversed.
Deleting at the keyboard-
•Select the object or objects to delete using any available selection functions (see also Selecting objects);
•at the keyboard, delete with the backspace key or the Delete key. OR:
•Select the object or objects to delete using any available selection functions (see also Selecting objects);
•Activate the object deletion tool with a single click; •use the mouse cursor to point at the object to delete;
Axial symmetry:
Symmetry about an axis can be applied at any time while using the tools described above as follows:
•Point at the object to be transformed with the mouse pointer until its outline appears in black;
•type H at the keyboard to apply horizontal symmetry (ie axial symmetry about a vertical axis) OR…
•type V at the keyboard to apply vertical symmetry (ie an axial symmetry about a horizontal axis) ;
•Validate the modification to the object in one of two ways : •either type Enter at the keyboard •or double-click on the modified object.
Duplicating objects:
While using any of the functions presented above, you can effect a Copy/Paste action on selected objects. It might prove useful, for example,
to make a copy of an object before modifying its geometry or its fields. Proceed as follows :
•Select the object or objects to duplicate using any available selection tools (see also Selecting objects) ;
•Point at the object to duplicate with the mouse cursor; its outline plus the rectangular space it occupies appear in black;
•Type in succession the keyboard shortcuts CTRL C (to copy the object) and CTRL V (to paste the object).
Cancelling geometric transformations:
Geometric transformations such as those listed below can be cancelled:
•Geometry editing operations;
•Object displacement operations;
•Object rotations;
•Re-sizing of objects. Cancellation is only possible once the transformations have been validated.
Proceed in one of two ways : •following the validation of a geometric transformation, the keyboard shortcut CTRL Z enables restoration of the original status of the transformed object. At this point, two manipulations are possible : •the original outline can be validated (confirmation of the cancellation) using the Enter key on the keyboard, or using a double-click on the object itself; •the keyboard shortcut CTRL R can also be used to restore the object’s pre-cancellation status.
•If cancellation is confirmed using one of the methods given above, it is still possible to cancel the cancellation by typing again the shortcut CTRL Z, thus re-establishing the geometric transformation applied initially.
