SIGN DATA

This structure is used in Moskito by procedures which want to take over the drawing on the screen and the Plotten. There are two beginning points.

•A routine which wants to generate from the data bank graphic issues and, besides, the plot machine of Moskito uses, puts down here her parametres and functions.

•A driver of special plotters is called with this structure.

Description of the fields

colorTable (ULONG [17])

RGB values with 17 firmly defined pencils. The colours are described in the table manual under pencil colours.

signaturTabelle (int)

Number of the signature table which should be used to the issue.

flags (long int [100])

Counter to the commitment of the issue options. The up to now following are defined by hundred counters:

FLAG_DRAWSEGMENT_BEFORE                0

Before the issue of the objects the sign buffer is given. On the screen the marks and auxiliary lines appear immediately with beginning of the drawing.

FLAG_DRAW_AREAS                        1

Surfaces are given.

FLAG_BREAK_ON_REQUEST                2

The plot machine should react at interruption standards of the user.

FLAG_DRAWSEGMENT_AFTER                3

After the issue of the objects the sign buffer is given once again. On the screen appear the marks and auxiliary lines about the graphics.

FLAG_STD_LINES                                4

No issue of line signatures.

FLAG_STD_AREAS                        5

Issue of full surfaces, even if shadings are given.

FLAG_REAL_CLIP                                6

The clipping should occur precisely, so at line level in the last step of the issue. The calculation is time-consuming and, therefore, can slow down spending.

FLAG_OPTIMIZE                                7

The issue should be optimised, even if small impurities originate (e.g., texts which are too small, remove).

FLAG_INITIALIZED                                8

The mark that the structure was initialized. Without this Flag defaults are used while printing.

FLAG_USE_WINDOWSFONT                9

Texts are given about the entry addText (). If is this Flag 0, texts with the built-in text generator are disassembled in lines.

FLAG_DRAW_DEFAULT                        10

The lines for which no colour information exists in the tables are drawn in standard colour. If no colour information is available such lines are suppressed.

FLAG_BIGCURSOR                                11

The crosshair cursor is shown. If the Flag is not put, the mouse cursor is helped to pull instead of this by the tray.

FLAG_DELETERASTER                        12

Grid data are released after the drawing again to save storage space. Sensibly while printing, because the data are not needed again.

FLAG_NO_DRAW_PSY                        13

The symbols in the bases of lines are not drawn. The line becomes durchgezeichnet.

FLAG_CONTINOUS_LINESEGMENTS        14

Pattern about bases away

FLAG_BUSY                                15

Herewith on the screen the hourglass is put over the graphic arts window.

FLAG_NO_TEXT_DRAW                        16

Texts are not drawn.

FLAG_NO_SYMBOL_DRAW                        17

Symbols are not drawn. The symbolic elements are meant. Point symbols in the bases of lines are influenced with FLAG_NO_DRAW_PSY.

FLAG_NO_RASTER_DRAW                        18

Grids are not drawn.

FLAG_NO_STRING_DRAW                        19

Lines are not drawn.

FLAG_NO_POINTELEM_DRAW                20

Point elements (marker) is not codrawn.

FLAG_PAPER_DRAW                        21

The issue occurs on paper. Accordingly detail drawings are carried out and accompanying documents are coprinted.

root (PROOT)

Act to the data bank.

device (int)

rekursionsStufe (int)

Number of the selfcalls of the plot procedure. With depth 4 the Plotten is broken off to prevent an infinite Rekursion. A rekursiv defined symbol is probably given with a Rekursion.

clip (int)

Except company, substitutes with the Flag FLAG_REAL_CLIP.

plotFileName (char *)

Name of the file in which the plot is filed.

userData (void *)

Aloof for IO routines

blattname (char *)

Name of the plot, as he can be spent in the sheet frame.

offsX, offsY (stands in)

It is added to the calculated co-ordinate values, before the issue occurs.

rotation (stands in)

Rotation corner of the issue. It is given in curve measure.

linescale (stands in)

The graduation which is used for line signatures (Strichlierung and width), because these are given in 1/100 mm in expression. A line width of 50 is given with Linescale 75 and issue graduation 125 (in scaleAfterOutput) with a real width from 50*75/125/100 = 0.3 mm.

textscale (stands in)

With this value all text dimensions are calculated in the issue, the algorithm is the same like with lineScale.

symbolscale (stands in)

With this value all symbolic dimensions are calculated in the issue, the algorithm is the same like with lineScale.

scaleAfterOutput (stands in)

According to the issue calculation all co-ordinates are divided by this value. While printing the graduation, on the screen issue 1 stands here ordinarily. This can be different in symbols.

scaleBeforeUse (stands in)

All co-ordinates after the reading from the German Railways by this value multiply. Serves, e.g. to bring symbols on her real size.

top, left, bottom, right (stands in)

Co-ordinate area of the issue medium. Information occurs in metre.

rotX, rotY (stands in)

Fulcrum for the rotation. If the rotation corner is not 0, the co-ordinates are turned around this point. A point with the co-ordinate (rotX, rotY) lands after the rotation in the position (0,0).

pixelSize (stands in)

Size 1 pixel on the issue device in metre. If the Flag FLAG_OPTIMIZE is put, are left out writings and vectors which are too small for this value. Circles are always disassembled with the help of this value in line segments.

tools (TOOL_TAB *)

keys [MAX_KEYS] (KEY)

Inside uses to the buffer of object keys.

keyCount (USHORT)

Number of real values in keys

addLine (procedure pointers)

The driver of the issue device puts down here the sign routine for lines. If no routine is put down, no line issue occurs.

Parametre

data (struct SIGN DATA *)
