Editing of image for vector objects

Vector objects are displayed by out-of-scale oriented conventional symbols and have one or two points of metrics. For providing orientability and scalability the vector symbol consist of parts: lines, polygons, circles, etc. The symbol size on a map in horizontal and vertical lines is marked by external arrows and it is indicated in millimeters.

For binding a symbol to the first point of the metrics the origin is used. The origin beginning specifies a point of  binding of a symbol. The horizontal axis of symbol at visualization is combined with a piece from the object metrics. Editing of a screen and printer view of vector object differs by the linear sizes of chains (thickness of a line, length of a stroke in a screen view in pixels, and in a printer view in millimeters (to within 0,01)).

Window of editing of symbol metrics occupy the basic part of dialog. To the left of it the column of symbol colors is located (used colors are displayed only).

From below there are keys: Save, Cancel, Origin and Help.

The list of symbol sizes allows to set the size of working field 60, 90 and 120 pixels.

Image of symbol shows symbol in scale 1:1. Offset fields specify size of displacement of the cursor in horizontal and in vertical lines from last entered point in pixels. Coordinates fields show  cursor position in horizontal and in vertical lines from the left upper corner in pixels.

On the right and from below of Window of editing of symbol metrics are located the external arrows, showing what part of symbol has size on vertical (Vertical Size) and on horizontal (Horizontal Size) accordingly (at displaying of a map in initial scale).

The vector object consist of parts: polylines, circles, polygons.

The chosen (highlighted) part is editing. The type of a part (item) can be: Square, Line, Circle, Filled circle. If type of a part is Line or Circle - it is possible to choose a type of a line: a line or a dashed line. Color of a part gets out at pressing by mouse on a rectangle of color (of possible colors), or at pressing by mouse on respective color in a column of symbol colors.

At updating the chosen chain type the list Type is filled only by suitable types (for example, it is possible to replace a line by the area, and it is impossible to replace  by circle).  

For change of the chain metrics or input of the metrics for a new chain it is necessary to use  Toolbar for work with a symbol part (Edit item).

Creation of symbol part.

For creation of a symbol part it is necessary to choose one of modes of part creation:  

- create line

- create dot (dotted line)

- create a square chain

- create text.

In this mode at first choose Type, Image and parameters of a part, then by pressing of the left mouse button create points. For cancelling the entered point press BackSpace key. For finishing a part creation use double click of the left mouse button or pressing the left and right mouse buttons simultaneously.

During input of a part it is possible to change the size of a field and parameters. To undo an input of a part or changes of parameters of a part press Ctrl and the right mouse button or Ctrl+C. If the type of a part is the square - the metrics will be closed automatically.

Created titles in vector objects can have the constant text and the text specified by semantics of object. Parameters of the text are entered equally. For the titles by semantics of object choose a code of necessary semantics and fill value of semantics by default (this text is deduced at absence of given semantics at object). If type of semantics is the classifier, it is possible to specify, decipher value of semantics or not (field " Value to not decode "). It is possible to include references to semantics of object into constant titles too. If to include # into the text and further a code of semantics, instead of this combination the value of semantics will be inserted. For example: the text of the constant title - "Length - #2 / width - #11", on the screen: "Length - 32.20 / width - 14.50". If the object does not have any of declared semantics, the text is not displayed. At presence even one semantics instead of absent semantics - a blank ("Length - / width - 14.50").

At creation of a part of type a circle the metrics is created automatically.

For creation of a circle it is necessary to press the left mouse button (to specify the center). Not releasing the button pull the appeared circle to the achievement of suitable radius. Creation of a part is finished by release of the left mouse button.

If the circle of the chosen radius will be outside the limits of a field - it will be cut. The type of the created part varies onto the polygon or a line accordingly.

Other modes in Toolbar for work with a part of symbol are active only at presence of the chosen part.

For a choice place the cursor above a point of a part. Press the left mouse button. The chosen part is highlighted and blinks. If through a point pass some parts of symbol, movement to the next part is carried out by repeated pressing the left mouse button.

At the chosen part it is possible to change parameters (color, etc.)

Copy of the chosen symbol part.

The copy of the highlighted part of symbol is created. The created part is chosen.

Change of a part.

Change of metrics for the chosen part. In the given mode the point of a part nearest to the cursor unites with him by a line and becomes active. For deleting an active point press Delete key, for  insert press Insert key. For moving a point press the left mouse button. With pressed button move to the necessary position.

For change of the metrics of a circle or a filled circle specify necessary radius by mouse and press the left mouse button.

Move the part.

Press the left mouse button. With pressed button move onto the necessary place. At release of the button the metrics will be recorded. If at movement the part quits the working area, the sound signal is given. The part does not be moved out of area border.

Delete part.

At activation of the given mode the active part is deleting.

Flip part.

In this mode for objects with one or several axes of symmetry it is convenient to create new parts. Specify by the left mouse button the beginning of an axis of symmetry. Behind the cursor the mirror will be drawn. Specify the end of an axis of symmetry. (Length of a mirror has no value - important only its direction). A part - sample remain active.

Group of fields "Base".

The size of vector objects usually decreases or increases according to map scale. You can set No press flag if the object is very important and it is necessary to see it in any scale.

If Stretch flag is established the symbol proportionally will be compressed or be stretched so, that the beginning of reading (origin) will coincide with the first point of the metrics, and the end of reading (origin) will coincide with the second.

For objects which axis should be located strictly horizontal, not dependent on the metrics, set Horizontal flag.

On a map may be objects which should symmetrically be rotated on maps to the right or to the left. For example: lanterns can be left-hand and right-hand. It is possible to describe these symbols by one vector symbol, having established to it Flip (Mirror) flag.

Then, if the symbol is digitized from right to left, we shall receive a left-hand lantern and right-hand in the other case. The usual vector symbol in these conditions will turn over head first.

Base group of fields include vertical size and horizontal size.

The given sizes are the sizes of areas marked by external arrows (at initial map scale). Sometimes conveniently to set the size not dimensions of a symbol, and its separate part. If a component of a symbol is the circle - most conveniently to set area on a circle and to specify its real radius. If one of the sizes is 0, the symbol will be stretched or be compressed proportionally. If both sizes are 0 - each cell will have the size about 0.25 mm.

The Block bookmark is intended for creation of polygonal chains with a complex contour (composed of arcs and lines). On the bookmark there is a toolbar for working with chain blocks and windows for entering block parameters (colors).

There are three groups in the tool bar:

- creating a block;

- choice of block for change;

- buttons for work with the chosen block.

Group of buttons for creating a block: - Create block of chains. After pressing this key, by usual tools the user can create chains (lines and arcs) that consistently form a complex contour. To complete the creation of the block, click on the Save block button. - Collect block. After pressing this key, the user can select chains by pressing the left mouse button, to confirm the selection, press the Space key. The chain added to the block will be highlighted and its end will be highlighted. To complete the creation of the block, click on the Save block button. - Save block. By pressing this key, the user must complete the creation of block. Button for selecting a block. Button for selecting a block. If this button is pressed, then by clicking the left mouse button, not individual chains, but chains blocks are selected.

Group of buttons for working with the selected block: - Break block of chains. After pressing this key, the chains of the selected block are considered as separate.

- Delete block - all chains of the block are deleted.

- Move block - the block moves as a whole.  

- Cut block - Cut from the block of chains of a hole specified by a separate chain or another block. After pressing this key, the user can select chains or blocks by pressing the left mouse button, to confirm the selection, press the Space key. If the hole was cut by a block - to see it, the block needs to be deleted or moved.

Chains of blocks can be removed, corrected and shifted as usual chains.

If one of the block chains gets into the group, the operations with the group (moving, deleting, flip) are extend onto the whole block.

Operations: chain above, below and etc are extend onto the entire block.

Toolbar for work with symbol as a whole. Take from buffer.

Write down into buffer.

At editing of vector symbol it is possible to write down a symbol into buffer, then to add this displaying into other symbol, quite possible even from other map. The new symbol is added to the available image. If it is necessary simply to copy a symbol - at first clear a field.

To change the size of a symbol, at placing the cursor above a line of the size (cursor image will change) press the left mouse button and, not releasing it, move a line to a new position.

       Move a symbol.

In this mode all symbol entirely moves in a working field.

Press the left mouse button. Around of the symbol the dimensional frame will appear. Not releasing the left mouse button, move a dimensional frame. At button releasing the metrics will be recorded. If at movement the symbol quits the working area, the sound signal is given.  The symbol does not be moved out of area border.

Mirror for whole symbol (Flip symbol).

By using this mode for vector objects with one or several axes of symmetry it is convenient to create new parts. Specify by the left mouse button the beginning of an axis of symmetry. Behind the cursor "the mirror" will be drawn. Specify the end of an axis of symmetry. The length of a mirror has no value - important only its direction. All parts of symbol symmetrically will be reflected.

Deleting of whole symbol. Cleaning of all working field.  

At pressing onto the right mouse button a pop-up menu appear. There some modes are duplicated. Also it is possible to change the order of displaying on the screen of overlapped symbol  parts. It is possible to move an active part to the highest part or the lowest part of displaying, or to move up and down by steps.

The important element in a vector symbol is origin. The beginning of origin specifies a binding point of symbol. The line of origin lays along metrics, except for symbols with a Horizontal flag. If the symbol is stretched, it  proportionally will be compressed or be stretched so, that the beginning of origin will coincide with the first point of the metrics, and the end of origin will coincide with the second point.

Press Origin button to set an origin of symbol. By pressing of the left mouse button specify the beginning and the end of origin (origin for symbol is displayed by red color).
