I'm trying crop a signature capture so that I only save the image and not the white space around it. It seems to work if I set my simulator's color depth to 2 colors (black and white). The drawing becomes more garbled as I increase the color depth on the Sim.
Here is the code: theGadgetIdx = FrmGetObjectIndex(frmP, gadgetID); data = (SignatureGadgetData *)FrmGetGadgetData(frmP, theGadgetIdx); //This is a function I wrote to return the dimensions of the image if (!ExistsDrawingCanvasBitmap(data, minX, maxX, minY, maxY)) return 0; //Copy the drawing from the original bitmap to a new bitmap of the cropped size newBitmap = BmpCreate(maxX - minX + 1, maxY - minY + 1, 1, NULL, &err); newBitmapWin = WinCreateBitmapWindow(newBitmap, &err); //create rectangle to indicate where to copy from in the source bitmap rect = new RectangleType; rect->topLeft.x = minX; rect->topLeft.y = minY; rect->extent.x = maxX - minX + 1; rect->extent.y = maxY - minY + 1; WinCopyRectangle (data->bitmapWin, newBitmapWin, rect, 0, 0, winPaint); I'm guessing this might have something to do with color tables. I've played around with that with no success but I was probably doing it wrong.
