Syntax

Drawing a point by specifying its coordinates Hide the details

<Image control>.DrawPoint(<X coordinate> , <Y coordinate> [, <Point color> [, <Opacity>]])
<Image control>: Control name
Name of Image control to use.
<X coordinate>: Integer
Horizontal position (in pixels) of the point to draw.
<Y coordinate>: Integer
Vertical position (in pixels) of the point to draw.
<Point color>: Integer or constant (optional)
Color that must be assigned to the point. This color can correspond to:
If this parameter is not specified, the color of the point:
  • is Transparent if <Image>.Pen was not used beforehand,
  • corresponds to the color specified in the last call to <Image>.Pen.
<Opacity>: Optional integer
Opacity of color, included between 0 (transparent) and 255 (opaque). An opacity sets to 128 indicates that the relevant pixel will have a transparency of 50% when it is drawn on the screen or saved in an image in PNG format.
Remark: This opacity will be taken into account if the drawing found in the image was initialized by the dWithOpacity constant (<Image>.StartDrawing).

Drawing a point via a Point variable Hide the details

<Image control>.DrawPoint(<Point> [, <Point color> [, <Opacity>]])
<Image control>: Control name
Name of Image control to use.
<Point>: Point variable
Name of the Point variable containing the coordinates of the point to draw.
<Point color>: Integer or constant (optional)
Color that must be assigned to the point. This color can correspond to:
If this parameter is not specified, the color of the point:
  • is Transparent if <Image>.Pen was not used beforehand,
  • corresponds to the color specified during the last call to <Image>.Pen.
<Opacity>: Optional integer
Opacity of color, included between 0 (transparent) and 255 (opaque). An opacity sets to 128 indicates that the relevant pixel will have a transparency of 50% when it is drawn on the screen or saved in an image in PNG format.
Remark: This opacity will be taken into account if the drawing found in the image was initialized by the dWithOpacity constant (<Image>.StartDrawing).
Remarks

Coordinates

Coordinates are given with respect to the top left corner of the image (coordinates: (0.0)).
