)įor example, the following image shows a single point drawn in Red rotated in to each sector but not reflected, and a single point drawn in Blue that is both reflected and rotated in each sector.Īttach a listener to the "Clear" component in your control panel to allow the user to clear the doily display so that all that remains displayed are the lines representing the sectors as drawn in Part Two.Īttach a listener to the "Undo" component in your control panel to allow the user to repeatedly remove some previously drawn points from the doily. (Hint : think carefully about how to reflect the drawn point - look for symmetry in the whole doily rather than focussing on symmetry in each sector. Whenever this flag is true, ensure that every point drawn is also drawn reflected across the sectors (and repeated in every sector). ![]() Now, add a boolean flag to record whether the points of the doily should be reflected or not. (Hint: look at 2D to help, in particular the method rotate(double theta, double x,double y).) That is, if the user draws some points in one sector, the same points should appear (suitably rotated) in every sector. ![]() Draw wherever the mouse is dragged but in addition, draw the same graphics repeated in every sector. Bear in mind that the number of sectors to draw will change during operation of the application.Īttach a listener to the main panel to allow the user to draw by dragging the mouse. For example, the image below shows a display with 12 sectors. In the large display panel, draw lines from the centre point out to the edge of the display (you may draw lines all of the same length) to divide the display area in to sectors. ![]() In the gallery panel, provide a layout for displaying up to 12 images and a button to remove a selected image from the gallery. In the contol panel, add appropriate components to form an interface for the following functionality:Ībility to change the colour and size of the pen for the doily to be drawn inĪbility to change the number of sectors that the display is divided intoĪbility to toggle between showing the sector lines, and whether or not to reflect the drawn points.Ībility to undo the previously drawn pointĪbility to save the current doily image in a gallery of images Here are the steps to building the application which you must follow:Ĭreate a GUI application using a JFrame that holds a large display panel for drawing the doily, a control panel for the various settings and panel to display a gallery of previously drawn doilies. Here is an example Digital Doily drawn using 24 sectors In addition to this the points are reflected across each sector. Any point drawn in any sector is also drawn at the same relative position in every other sector. To achieve this, the drawing area is divided in to sectors radiating out from a central point. A digital doily is a repeated pattern of mouse drawn graphics intended to resemble a lace doily. We use acid-free papers and canvases with archival inks to guarantee that your prints last a lifetime without fading or loss of color.** Assignment Instructions: Digital Doilies **įor this assignment I would like you to build a Java application that creates a Graphical User Interface for drawing Digital Doilies. All of our prints are produced on state-of-the-art, professional-grade Epson printers. ![]() Pixels Canvas Prints is one of the largest, most-respected giclee printing companies in the world with over 40 years of experience producing museum-quality prints.
