CAD parametric drawing text (Web version)

In the CAD design, the need to draw text, the user can set the settings for text display attributes such as height.

The main use of Function:

_DMxDrawX::DrawText

Draw a single line of text. Details are as follows:

parameter	Explanation
DOUBLE dPosX	X coordinate of the position of the text
DOUBLE dPosY	Y coordinate position of the character
BSTR pszText	Text string
Double dHeight	Text height
DOUBLE dRotation	The angle of rotation of text
SHORT horizontalMode	Text horizontal alignment, 0 = kTextLeft, 1 = kTextCenter, 2 = kTextRight
SHORT verticalMode	Vertical alignment of the text, 1 = kTextBottom, 2 = kTextVertMid, 3 = kTextTop

_DMxDrawX::AddTextStyle1

Add a text style to the database. Details are as follows:

parameter	Explanation
BSTR pszName	Text style name
BSTR pszFileName	shx file name
BSTR pszBigFontFileName	big shx file name
DOUBLE dXScale	Text width scaling

js implemented Definitions:

the DrawText function () 
{ 
    // clear the currently displayed content 
    mxOcx.NewFile (); 
    // put back to black and white color 
    mxOcx.DrawColor = 0; 
    // create a layer called "TextLayer" 
    mxOcx.AddLayer ( "TextLayer" ); 
    // set the current layer to "TextLayer" 
    mxOcx.LayerName = "TextLayer"; 
    // draw a line text 
    // parameter a is the X coordinate position of the character; two parameters for the Y coordinate position of the character; parameters of three text string 
    // text height is four parameters; five parameters of the rotation angle of the text 
    // parameter six horizontal justification of the text, kTextLeft = 0, = kTextCenter. 1, 2 = kTextRight 
    // seven vertically aligned mode parameter text, kTextBottom =. 1, 2 = kTextVertMid, kTextTop. 3 = 
    // --------------------------- -------------------------------------------------- -------------------- 
    // write a text, 0,1 is left-aligned. 
    mxOcx.DrawColor = 65280;
    mxOcx.DrawText (0, 1900, "dream drawing control www.mxdraw.com 3.0", 100, 0, 0,. 1); 
    // ------------------- -------------------------------------------------- ------------------------------ 
    // write a text, 2,1 is the lower right-aligned. 
    mxOcx.DrawColor = 4556677; 
    mxOcx.DrawText (3000, 2100, "dream drawing control www.mxdraw.com 3.0", 100, -20, 2,. 1); 
    // ------------------ -------------------------------------------------- ------------------------------ 
    // specified style to draw text 
    mxOcx.AddTextStyle1 ( "MyTextStyle", "italicc.shx " , "gbcbig.shx", 0.7); 
    mxOcx.TextStyle = "MyTextStyle"; 
    mxOcx.DrawColor = 255; 
    mxOcx.DrawText (0, 3000, "dream drawing control 3.0 www.mxdraw.com", 100, 0, 0, 1);
    // ------------------------------------------------ -------------------------------------------------- 
    // write a TureType font 
    mxOcx.AddTextStyle2 ( "MyTrueTypeStyle", "black body", 0.7); 
    mxOcx.TextStyle = "MyTrueTypeStyle";
    mxOcx.DrawText (0, 3150, "dream drawing control www.mxdraw.com 3.0", 100, 0, 0,. 1); 
    mxOcx.ZoomAll (); 
    mxOcx.UpdateDisplay ();
