View Full Version : Displaying image processed in a IC into another one
May 6, 2004, 19:44:33
I have been working with the IC activeX control for doing image processing. What I want to do is the next:
1.- Display image available in one IC window
2.- Select ROI with mouse events.
3.- Make image processing in ROI.
4.- Display ROI processed in a second IC window.
As far as I have been working I already have the 3 firts steps but now I want to display de ROI processed in other IC window, but I have no idea on how to do this, I mean I don't know how to configure the second IC. Could you please help me?
Thanks a lot.

For drawing a ROI with the mouse see the Advanced Image Processing sample in the samples\vb6 directory of your IC Imaging Control installation.
You should use a PictureBox control instead of a second IC Imaging Control.
To display the ROI in a PictureBox, your should use the PSet method of the Picture and draw pixel by pixel.

Hi again, My last questions were on the pointer of type Pointer, I have been working on it and if I cast this to other pointer of type INTEGER I can get the data but I think there is something wrong with the answer, here is my delphi code:
procedure TForm1.ICImagingControl1ImageAvailable(ASender: TObject;
//HERE I DO THE CAST
pValue := pPixel;
//HERE I GET THE DATA OF pPixel in an edit Box
//Accessing via the ID Array
(* pPixel points directly to the beginning of the image pixel data *)
When running this program I get that pValue holds a number like (-117222558) while ID[0,0] holds (245) what I think is the greyscale number. My question is how can I get the same greyscale using the pointer.
Thanks a lot.

as i wrote in the other thread, my Delphi experiences are too poor for this issue. Sorry.
