項目運行程序exe根目錄截圖：
Halcon程序運行是需要證書的，在license裡面，參考截圖裡面的程序dll，需要都要放在exe根目錄裡面，不然運行會報錯
程序識別效果：
光線很暗的情況下，也可以正確識別
qr二維碼尺寸比較小時，也可以正確識別

//String: A tuple of strings containing the text message to be displayed
//CoordSystem: If set to 'window', the text position is given
// with respect to the window coordinate system.
// If set to 'image', image coordinates are used.
// (This may be useful in zoomed images.)
//Row: The row coordinate of the desired text position
// A tuple of values is allowed to display text at different
// positions.
//Column: The column coordinate of the desired text position
// A tuple of values is allowed to display text at different
// positions.
//Color: defines the color of the text as string.
// If set to [], '' or 'auto' the currently set color is used.
// If a tuple of strings is passed, the colors are used cyclically...
// - if |Row| == |Column| == 1: for each new textline
// = else for each text position.
//Box: If Box[0] is set to 'true', the text is written within an orange box.
// If set to' false', no box is displayed.
// If set to a color string (e.g. 'white', '#FF00CC', etc.),
// the text is written in a box of that color.
// An optional second value for Box (Box[1]) controls if a shadow is displayed:
// 'true' -> display a shadow in a default color
// 'false' -> display no shadow
// otherwise -> use given string as color string for the shadow color
//
//It is possible to display multiple text strings in a single call.
//In this case, some restrictions apply:
//- Multiple text positions can be defined by specifying a tuple
// with multiple Row and/or Column coordinates, i.e.:
// - |Row| == n, |Column| == n
// - |Row| == n, |Column| == 1
// - |Row| == 1, |Column| == n
//- If |Row| == |Column| == 1,
// each element of String is display in a new textline.
//- If multiple positions or specified, the number of Strings
// must match the number of positions, i.e.:
// - Either |String| == n (each string is displayed at the
// corresponding position),
// - or |String| == 1 (The string is displayed n times).
//
//
//Convert the parameters for disp_text.

下面有個ECC200二維碼識別類：
如果要替換成識別ECC200二維碼，則直接將QR識別類替換為此類就好
