FEATURE REQUEST: Custom Shape Drawing to page base on user need

[dineshnaikb]

Custom Shape Drawing: The ability to freely draw custom shapes (lines, rectangles, circles, etc.) directly on the PDF page. This would allow users to highlight specific areas or add annotations for better clarity.

i have tried doing this but I have to do it more smooth...

onInteractionUpdate: (details) {
              setState(() {
                points.add(details.localFocalPoint);
              });
            },
            onInteractionStart: (details) {
              setState(() {
                points.add(details.localFocalPoint);
              });
            },
 pagePaintCallbacks: [
              textSearcher.pageTextMatchPaintCallback,
              _paintMarkers,
              penpointer,
            ],



 final List<Offset> points = [];
  

penpointer(Canvas canvas, Rect pageRect, PdfPage page) {

      Paint paint = Paint()
        ..color = Colors.black
        ..strokeCap = StrokeCap.round
        ..strokeWidth = 5.0;
      for (Offset point in points) {
        canvas.drawCircle(point, 5.0, paint); // Draw a circle with radius 5
      }
    // }

  }

base on pages to page and scroll issue to fix ...... and also keep track for undo...

Hey @espresso3389 , great library any idea when this will be picked up?

[espresso3389]

Basically, I think it's possible to implement this without pdfrx change. And, I don't plan to implement this because

• pdfrx is supposed to be customizable enough to implement the feature (you can do it by yourself!)
• if I implement only drawing feature, people suddenly request me to implement some save/load feature
• it's too much time consuming (and not productive) to implement such feature that fulfills everyone's requests

If you have any kind of more "solid" questions or problems during implementing the feature, please ask me about that.

As a side note, if you want to implement drawing feature, just adding points on every event is not a good choise. You had better use paths or lines at least.
