CoordinateImageToImageControl (Function)
In french: CoordonnéeImageVersChampImage
Converts the coordinates of a rectangle in the image to the corresponding coordinates in the Image control. This function is used to match the coordinates of the source image to the coordinates displayed in the Image control.
Example
// Load image for OCR
ImageForOCR is Image = dLoadImage(MyImage)
// Display a thumbnail of the image in the control
IMG_Thumbnail = ImageForOCR
// Detect text areas
arrAreas is array of Polygon = OCRDetectTextArea(ImageForOCR)
// Draw rectangles in the thumbnail
dStartDrawing(IMG_Thumbnail)
FOR EACH rect OF arrAreas
// Transform polygon into a rectangle (here we consider that the polygon has a right angle)
recTemp is Rectangle
recTemp.X = rect.Point[1].X
recTemp.Y = rect.Point[1].Y
recTemp.Width = rect.Point[2].X - rect.Point[1].X
recTemp.Height = rect.Point[3].Y - rect.Point[1].Y
   
let rectImage = CoordinateImageToImageControl(IMG_Thumbnail, recTemp)
dRectangle(rectImage)
END
Syntax
<Result> = CoordinateImageToImageControl(<Image control> , <Coordinates to convert>)
<Result>: Rectangle variable
Rectangle variable that corresponds to the rectangle in relation to the Image control.
<Image control>: Control name
Image control used.
<Coordinates to convert>: Rectangle variable
Name of the Rectangle variable that corresponds to the rectangle in relation image.
Remarks
  • The conversion takes into account the display mode of the image.
  • The function is ignored if the displayed image is repeated.
