Command DRAW
 
Description Draw or update a Line, Vector, Box, Circle  or Graph of size X,Y. The entities can be an outline or filled.
The colour can be enhanced using alpha blending within the draw style.
Graphs of a different colour can be superimposed on top of each other.
Faster display updates occur if draw uses a solid background colour (ie no alpha blending). 
DRAW accepts VARs, signed/unsigned integers
             (U8, U16, U32, S8, S16, S32), floats (FLT) and pointers (PTR)
DRAW( PTR, VAR|INT|FLT|PTR, VAR|INT|FLT|PTR, Style );
             Note PTR refers to the entity being pointed to by PTR and not
             the PTR itself. Use LOAD( PTR > "Name" ); to set a pointer.
 
Syntax/Parameters DRAW(Name,X,Y,Style)
DRAW(Name,X,Y,Style,PosX,PosY);
DRAW(name,length,angle,stVector);
 
Style It is possible to specify transparency values with colours if the colour is entered as a 32-bit hex number the top 8 bits specify the alpha blending level.
col = \\aarrggbb;     back = \\aarrggbb;   where  aa = alpha level.
For example, col = \\80FFFF00; gives 50% transparent yellow.
Support for opacity -  v49.00.

STYLE(gstyle,DRAW)  {   
    type=trace; //The shape to draw. type = B/Box; C/Circle;  L/Line;, T/Trace; P/Pixel; y/yBar; x/xBar;  v/Vector;
    maxX=100;  // Not required except for dynamic rotation where the maximum width is declared
    maxY=100;  // Not required except for dynamic rotation where the maximum height is declared
    col=green;  //Specify the line border colour of the shape. Use hex, colour name + alpha
    back=black; //Specify the fill colour of the shape. Use hex, colour name + alpha
    opacity = n;  // n = 0..100 where 0=transparent..100=opaque (default=100)
    width=3;    //Specify the line border width of the shape default = 1
    rotate=0;     //  Specify the rotation of the shape with respect to the screen. 0,90,180,270
    curRel=cc;   //specify placement relative to cursor. CC Centre Centre , TC Top Centre etc.
    xOrigin=50;   //specify graph x origin wit respect to declared graph
    yOrigin=50;  //specify graph y origin wit respect to declared graph
    xScale=200; //scale the value automatically to fit the graph
    yScale=200; //scale the value automatically to fit the graph
    xScroll=1;    //define scroll direction and increment 1=left to right one pixel, 0=no scroll
    }
 
Options Graphs - v47.00   
A number of graph styles now exist as draw types:
  type=p; type=pixel;     // Pixel Scatter - places a point at x,y
  type=t; type=trace;     // Trace/Line - joins the dots between current point and previous point.
  type=y; type=yBar;      // Bar Y - draws vertical line from 0 to y and clears from y+1 to ymax
  type=x; type=xBar;      // Bar X - draws horizontal line from 0 to x and clears from x+1 to xmax
           
 The origin on the graph can be changed
   xOrigin=val; // (default=0)
   yOrigin=val; // (default=0)

 The scaling of pixels can be set:
   xScale=val; // (default=100.0) [val can be float and is a percentage]
   yScale=val; // (default=100.0) [val can be float and is a percentage]
Note to draw graph with 0,0 at top and n,n at bottom, use yScale=-100;

The graph can be made to scroll (currently right-to-left only supported)  
   xScroll=val; // where val=0 (default - no scroll); val=n (scroll left n pixels before each plot

Please refer to the ADC analogue input section for a graph application example.

 Graph Displaying Problems v49.37
 * Added bounds check to prevent drawing outside of graph area.
* Fixed line wrapping within graph area.

 DRAWing of Graphs - Trace Line Should Not be Wrapping - v49.42
* Improved graph trace drawing.
* Solved problem with trace line wrapping when rendering a graph.
* Extended graphics area to encompass line width and modified page rendering to deal with windowed pixels.

 DRAWing of Ellipses and more DRAW parameter options - v49.37
 * Added ellipse drawing, specify type=ellipse or e in the STYLE
* Added more DRAW command options
DRAW( name, x ); // Circle or Square modification: width=x; height=x;
DRAW( name, x, style ); // Circle or Square definition: width=x; height=x;
DRAW( name, x, y ); // All Shapes modification: width=x; height=y;
DRAW( name, x, y, style ); // All Shapes definition: width=x; height=y;
DRAW( name, x, y, s, a ); // Ellipse Arc modification: width=x; height=y; startAngle=s; arcAngle=a;
DRAW( name, x, y, s, a, style ); // Ellipse Arc definition: width=x; height=y; startAngle=s; arcAngle=a;
* Notes:
- 0 degrees is at 12'o'clock and positive angles are clockwise.
- The style for an arc must be defined to encompass the size of the shape if drawn from 0 to 360 degrees.
- Further work required on the fill algorithm for ellipses.
* Added option for start angle and arc angle to be in radians or degrees depending on SYSTEM.angles setting. v49.48

Graphs to support alpha blending and opacity - v49.42
* New features of alpha blending and opacity with graphs
* Support for graphs when the display is rotated 90, 180 and 270 degrees

 Drawing Lines - v49.48
* New algorithm for line drawing implemented.
* Lines are created with anti-aliased edges.
* Vertical and horizontal lines are a special case and are rapidly created (as no anti-aliasing required).
* Line ends are now created perpendicular to the line rather than vertical or horizontal.
Drawing Vectors (Lines with length and angle) - v49.48
* Added new line type - vector - which is defined with a length and an angle.
STYLE( stVector, DRAW ) { type = v or vector; ... }
DRAW( name, length, angle, stVector );

where
'length' is line length,
'angle' is angle clockwise from 12'o'clock position. 'angle' is in degrees or radians depending on SYSTEM.angles setting.

New Line Draw CurRel options plus offset - v49.48
* Additional parameter can now be passed to DRAW() command for Line and Vector drawing which allow for the line to be offset relative to the cursor:
DRAW( name, length, angle, offset, stVect );
DRAW( name, length, angle, offset );
DRAW( name, length, angle, offset, stVect, xPos, yPos );
DRAW( name, width, height, offset, stLine );
DRAW( name, width, height, offset );
DRAW( name, width, height, offset, stLine, xPos, yPos );
* The offset parameter is ideal for the pointer on gauges and clocks where the point of rotation is a certain distance along the line
* New curRel options allow for better line placement.
SA, SB, SC // Start of line. SA = Edge A; SB = Edge B; SC = Centre
EA, EB, EC // End of line. EA = Edge A; EB = Edge B; EC = Centre
MA, MB, MC // Mid-point of line. MA = Edge A; MB = Edge B; MC = Centre
OA, OB, OC // Offset along line. OA = Edge A; OB = Edge Bl OC = Centre

* Example: Vector length = 100, angle = 125 deg, width = 5 (not to scale)


Draw() with structures - v49.48
* DRAW() command now accepts structure parameters for width/height/angles/offset.

Anti-Aliased Line Drawing - v49.48
* New algorithm for line drawing implemented.
* Lines are created with anti-aliased edges.
* Vertical and horizontal lines are a special case and are rapidly created (as no anti-aliasing required).
* Line ends are now created perpendicular to the line rather than vertical or horizontal.
 
Example Circle Example
DRAW(MyCircle, 32, 32, DrawCircle);
DRAW(MyCircle, 64, 64);                 //modified circle is double diameter.

 Built-In TEXT, PAGE, DRAW, and IMAGE Styles

10 Feb 14 

Show

A larger range of "default" styles has been added.

The built-in styles are prefixed by four characters as follows:
* Text Styles are prefixed by "DST_"
* Page Styles are prefixed by "DSP_"
* Draw Styles are prefixed by "DSD_"
* Image Styles are prefixed by "DSI_"

The styles are not created at start up. The style is only created the first time it is referenced from the users' project.

The style are created from the parameters within the style name itself, ie the colour black is taken from the actual name DSP_BLACK, so DSP_PINK would create a colour pink. These colours are from the colour table on the website.

Here are the rules/examples for each

Add a default TEXT style
DST_
DST_col
DST_col_fnt
DST_col_fnt_len
DST_col_fnt_len_row
DST_col_fnt_len_row_cur
Where
col = 'col' name or 3-digit hex or 6-digit hex (see "Colours" below)
fnt = 'font' 8, 16, 32 for Ascii8, Ascii16, Ascii32 or font name (see "Fonts" below)
len = 'maxLen'
row = 'maxRows'
cur = 'curRel'
Examples
TEXT(txt1,"Hello",DST_BLACK_16); // Create Text, colour = black; font = built-in Ascii16;
TEXT(txt2,"",DST_F30_fnt32_8_4); // Create Text, colour = \\FF3300, font = fnt32; maxLen = 8; maxRows = 4
TEXT(txt3,"",DST_RED_F32_8_4_TL); // Create Text, colour = \\FF3300, font = F32; maxLen = 12; maxRows = 4; curRel = TL

Add a default PAGE style
DSP_
DSP_col
DSP_col_img
Where
col = 'col' name or 3-digit hex or 6-digit hex (see "Colours" below)
img = 'image' image name
Examples
PAGE(pg1,DSP_BLACK){…} // Create Page, back = black;
PAGE(pg2,DSP_AB0056_libBg){…} // Create Page, back = \\AB0056, image = libBg;

Add a default DRAW style
DSD_
DSD_typ
DSD_typ_wid
DSD_typ_wid_col
DSD_typ_wid_col_fil
DSD_typ_wid_col_fil_cur
Where
typ = 'type' of shape (best to use the single letter here)
wid = 'width' of border
col = 'col' colour of border (see "Colours" below)
fil = 'back' colour of fill (see "Colours" below)
cur = 'curRel'
Examples
DRAW(dr1,100,20,DSD_BOX); // Create Draw, type = box;
DRAW(dr2,120,DSD_C_2_RED); // Create Draw, type = circle; width = 2; border colour = red;
DRAW(dr3,60,40,DSD_B_1_RED_FD0_TL,20,40); // Create Draw, type = box; width = 1; border = red; back = \\FFDD00; curRel = TL;

Add a default IMAGE style
DSI_
DSI_cur
Where
cur = 'curRel'
Examples
IMG(img1,libImg1,DSI_TL); // Create Image, curRel = TL;


The only limitations to this method is that the style name needs to fit within the 18 character entity name limit.

Colours
Where the styles take a colour for a parameter, then the value can be represented in one of three ways.
* The name of the colour can be specified as in the colour chart on the website, eg BLACK, BLUE, GOLD etc
* A 6 digit hexadecimal number can be used, eg 123ABC which converts to \\123ABC
* A 3 digit hexadecimal number can be used, eg FD0 which converts to \\FFDD00

Fonts
Where the style takes a font for a parameter, then one of two options are assumed.
* If the value is either 8, 16, or 32 then the built-in fonts Ascii8, Ascii16 or Ascii32 are used
* Otherwise the value is assumed to be the name of a font loaded by the LIB command, eg fnt64 from LIB(fnt64,"SDHC/name.fnt");

 DRAWing of Ellipses and more DRAW parameter options

10 Jun 13 

Show

* Added ellipse drawing, specify type=ellipse or e in the STYLE
* Added more DRAW command options
DRAW( name, x ); // Circle or Square modification: width=x; height=x;
DRAW( name, x, style ); // Circle or Square definition: width=x; height=x;
DRAW( name, x, y ); // All Shapes modification: width=x; height=y;
DRAW( name, x, y, style ); // All Shapes definition: width=x; height=y;
DRAW( name, x, y, s, a ); // Ellipse Arc modification: width=x; height=y; startAngle=s; arcAngle=a;
DRAW( name, x, y, s, a, style ); // Ellipse Arc definition: width=x; height=y; startAngle=s; arcAngle=a;
* Notes:
- 0 degrees is at 12'o'clock and positive angles are clockwise.
- The style for an arc must be defined to encompass the size of the shape if drawn from 0 to 360 degrees.
- Further work required on the fill algorithm for ellipses.

 Graphs - A number of graph styles now exist as draw types.

09 Jul 11 

Show

A number of graph styles now exist as draw types:
type=p; type=pixel; // Pixel Scatter - places a point at x,y
type=t; type=trace; // Trace/Line - joins the dots between current point and previous point.
type=y; type=yBar; // Bar Y - draws vertical line from 0 to y and clears from y+1 to ymax
type=x; type=xBar; // Bar X - draws horizontal line from 0 to x and clears from x+1 to xmax

The origin on the graph can be changed
xOrigin=val; // (default=0)
yOrigin=val; // (default=0)

The scaling of pixels can be set:
xScale=val; // (default=100.0) [val can be float and is a percentage]
yScale=val; // (default=100.0) [val can be float and is a percentage]
Note to draw graph with 0,0 at top and n,n at bottom, use yScale=-100;

The graph can be made to scroll (currently right-to-left only supported)
xScroll=val; // where val=0 (default - no scroll); val=n (scroll left n pixels before each plot

STYLE(gstyle,DRAW) {
type=trace;
maxX=100;
maxY=100;
col=green;
back=black;
width=3;
curRel=cc;
xOrigin=50;
yOrigin=50;
xScale=200;
yScale=200;
xScroll=1;
}
