Visual system design example (Halcon WinForm) -9. text display
2022-07-27 14:49:00 【11eleven】
After detecting the image, we need to mark the result with text output , Mark OK perhaps NG And other notes .C# Call in halcon Of HOperatorSet.DispText Has been an error .
The code is as follows :
public static void Disp_message(HTuple hv_WindowHandle, HTuple hv_String, HTuple hv_CoordSystem,
HTuple hv_Row, HTuple hv_Column, HTuple hv_Color, HTuple hv_Box)
{
// Local iconic variables
// Local control variables
HTuple hv_GenParamName = new HTuple(), hv_GenParamValue = new HTuple();
HTuple hv_Color_COPY_INP_TMP = new HTuple(hv_Color);
HTuple hv_Column_COPY_INP_TMP = new HTuple(hv_Column);
HTuple hv_CoordSystem_COPY_INP_TMP = new HTuple(hv_CoordSystem);
HTuple hv_Row_COPY_INP_TMP = new HTuple(hv_Row);
// Initialize local and output iconic variables
try
{
//This procedure displays text in a graphics window.
//
//Input parameters:
//WindowHandle: The WindowHandle of the graphics window, where
// the message should be displayed.
//String: A tuple of strings containing the text messages 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.
// You can pass a single value or a tuple of values.
// See the explanation below.
// Default: 12.
//Column: The column coordinate of the desired text position.
// You can pass a single value or a tuple of values.
// See the explanation below.
// Default: 12.
//Color: defines the color of the text as string.
// If set to [] or '' the currently set color is used.
// If a tuple of strings is passed, the colors are used cyclically
// for every text position defined by Row and Column,
// or every new text line in case of |Row| == |Column| == 1.
//Box: A tuple controlling a possible box surrounding the text.
// Its entries:
// - Box[0]: Controls the box and its color. Possible values:
// -- 'true' (Default): An orange box is displayed.
// -- 'false': No box is displayed.
// -- color string: A box is displayed in the given color, e.g., 'white', '#FF00CC'.
// - Box[1] (Optional): Controls the shadow of the box. Possible values:
// -- 'true' (Default): A shadow is displayed in
// darker orange if Box[0] is not a color and in 'white' otherwise.
// -- 'false': No shadow is displayed.
// -- color string: A shadow is displayed in the given color, e.g., 'white', '#FF00CC'.
//
//It is possible to display multiple text strings in a single call.
//In this case, some restrictions apply on the
//parameters String, Row, and Column:
//They can only have either 1 entry or n entries.
//Behavior in the different cases:
// - Multiple text positions are specified, i.e.,
// - |Row| == n, |Column| == n
// - |Row| == n, |Column| == 1
// - |Row| == 1, |Column| == n
// In this case we distinguish:
// - |String| == n: Each element of String is displayed
// at the corresponding position.
// - |String| == 1: String is displayed n times
// at the corresponding positions.
// - Exactly one text position is specified,
// i.e., |Row| == |Column| == 1:
// Each element of String is display in a new textline.
//
//
//Convert the parameters for disp_text.

HalconDotNet.HOperatorException:“HALCON error #5123: Wrong window type in operator disp_text”, No suitable solution was found , Say it's official BUG, Try to use WriteString Discovery can be used , The concise code is as follows :
imgSource.HControl.hWindowCtrl.HalconWindow.SetTposition(result.LoactionY.ToInt(), result.LoactionX.ToInt());// Set the output position
imgSource.HControl.hWindowCtrl.HalconWindow.SetColor(result.Color);// Set the color
imgSource.HControl.hWindowCtrl.HalconWindow.SetFont("-Mono-Bold-40-");// Set the font
imgSource.HControl.hWindowCtrl.HalconWindow.WriteString(result.Message);// Output content
Set the font completely without deformation :.SetFont($"-Arial-50-*-1-*-*-1-") 50 Is font size
