Rectangle to parallelogram
Am used to corel draw for designing but am new to adobe illustrator. In corel draw rectangular object when move my pointer in outer renctangle right or left side of the object ill get arrow key in bottom n top direction for making rectangle in parallelogram. Kindly help me in illustrator for such tools. I need to use this tool in illustrator. please check the used in corel draw below.
Select 'E' on your keyboard and you will get the right tool you need.
With this tool selected select the centre top point of your rectangle and hold shift and drag the way you want it.

Need help in this design, SHAPES!
Hello everyone.
I have a simple programming project but I'm getting caught up on what should be the super class.
Its shapes.
I have the following:
A Quadrilateral, Trapezoid, Parallelogram, Rectangle and Square.
At first I had it designed like
Quadrilateral is the super class of all the other shapes which I'm now seeing isn't the case.
A rectangle and Square is a special type of Parallelogram so my rectangle and square class is going to extend from the Parallelogram class.
Now would the Parallelogram class extend from the Trapezoid class and the Trapezoid class extend from the Quadralterial class?
Is that how the class diagram should look like?
THanks!I see what your saying.
Well the instructions are the following:
9.8 Write an inheritance hierarchy for classes Quadrilateral, Trapezoid, Parallelogram,
Rectangle and Square. Use Quadrilateral as the superclass of the hierarchy. Make the hierarchy as deep (i.e., as many levels) as possible. Specify the instance variables and methods for each class. The private instance variables of Quadrilateral should be the x-y coordinate pairs for the four endpoints of the Quadrilateral. Write a program that instantiates objects of your classes and outputs each object�s area (except Quadrilateral). The coordinates for the quadrilaterals are specified in an order that will produce a quadrilateral when drawn in the order given. You should use good software engineering principles, as practiced in Java, when developing this program. For example, you should use set and get methods in each class for accessing private instance data. There should be one additional class specified which is the Point class. The Point class consists of two values of private data, the x coordinate of the Point and the y coordinate of the Point.
Use the following as the definition of the main class QuadrilateralTest:

// TODO code application logic here
Quadrilateral quadrilateral = new Quadrilateral(1.1, 1.2, 6.6, 2.8, 6.6, 9.9, 2.2, 7.4);
Trapezoid trapezoid = new Trapezoid(0.0, 0.0, 10.0, 0.0, 8.0, 5.0, 3.3, 5.0);
Parallelogram parallelogram = new Parallelogram( 5.0, 5.0, 11.0, 5.0, 12.0, 20.0, 6.0, 20.0 );
Rectangle rectangle = new Rectangle( 17.0, 14.0, 30.0, 14.0, 30.0, 28.0, 17.0, 28.0 );
Square square = new Square( 4.0, 0.0, 8.0, 0.0, 8.0, 4.0, 4.0, 4.0 );
System.out.printf("%s %s %s %s %s\n", quadrilateral, trapezoid, parallelogram, rectangle, square );
The results produced by the program should look similar to the following:
Coordinates of Quadrilateral are:
(1.1, 1.2), (6.6, 2.8), (6.6, 9.9), (2.2, 7.4)
Coordinates of Trapezoid are:
(0.0, 0.0), (10.0, 0.0), (8.0, 5.0), (3.3, 5.0)
Height is: 5.0
Area is: 36.75
Coordinates of Parallelogram are:
(5.0, 5.0), (11.0, 5.0), (12.0, 20.0), (6.0, 20.0)
Width is: 6.0
Height is: 15.0
Area is: 90.0
Coordinates of Rectangle are:
(17.0, 14.0), (30.0, 14.0), (30.0, 28.0), (17.0, 28.0)
Width is: 13.0
Height is: 14.0
Area is: 182.0
Coordinates of Square are:
(4.0, 0.0), (8.0, 0.0), (8.0, 4.0), (4.0, 4.0)
Side is: 4.0
Area is: 16.0
The way he worded it sounded like he really wants to use inheritance to the max, so thats why I set it up like that.

After migrating data from Time Machine, some of my photos are not showing up in iPhoto LIbrary view. I get a 'dashed rectangle." When I click on it I get ' ! in a Triangle" When I click on that, I actually can see the photo. I want to see all my photos in 'Library' view, and I can't figure out how these photos seem to be arbitrarily hidden. Help, please.
Try these for the first attempt:
First be sure to have a backup copy of the library if you already don't have one.

How to pop up "Drag New signature rectangle" window from plug-in?
Hi, everybody
I am trying to create a menu that contains menuitem "sign". when the user click on menu->"sign" a window pop-up
asking for "Drag New signature rectangle" from the user.This window is same as poped up by default by digSig.
Problem is Which API should be used to pop this window.
Any kind of help will be welcomed.

I have all my photos organized in i-photo as both photos and events. When I opened in the past the images in each event or album appeared as icons on the sreen. Now when I open I only get a dotted line rectangle and only if I click I see the picture, which is really problematic when trying to see or select nay image.
I don't know if mistakenly I did something with the settings although I couls not find anything in preferences or any of the menus that could relate to this.Back up your iPhoto library, Depress and hold the option (alt) and command keys and launch iPhoto - rebuild your iPhoto thumbnails - this may take several tries
Also what version of iPhoto? What recently changed?

Check if a point lies inside a rectangle
Hi im making an application that displays a shape on the screen at different locations. The shape is a combination of an ellipse and a line. My problem is when i want to draw the shapes i created a method to check if the point given is contained by any other shape and if it is it should create a new point. However when the .contains(Point) method is run it doesnt reply true or false so my code just goes into an infinite loop and crashes.
Here is the checkpoint method that loops infintly
private void setPoint(Point pow) {
boolean anythingthere = false;
while (anythingthere==!true) {
Rectangle test = list.getBounds();
if (test.contains(pow)) {
int f = pow.x;
f = f+200;
int g = pow.y;
pow.setLocation(f, g);
System.out.println(pow);
f = 0;
else {
if (pow.x+150 > getWidth()) {
pow.setLocation(50, pow.y+180);
anythingthere = true;
i++;
}And because my shape is a combination of graphics2D shapes i created this method in its class to return the rectangle that bounds the shapepublic Rectangle getBounds() {
bound = new Rectangle(location.x,location.y,size,size);
return bound;
}Thanks for any help you can give im really stumped!!Hi thanks for your reply's. Thanks for tips on making my code nicer and efficient ive tried to do it throughout my project so hopefully its more readable now. The problem was to do with scope like one of you said so i moved a few things round and got it working. The problem was when i called the bounds of the rectangle it was returning the bounds using the last changed point which meant that every time i tested the loop the point was inside that bound so it basically looped infinitely. One line moved and it worked perfectly.
Thanks everyone -
How to access a placed PDF inside a rectangle and move it around
Hi, I have the following code which places a PDF inside a rectangle var f = new File("C:/pdf.pdf"); var doc = app.activeDocument; var thepdf =doc.pages[0].rectangles[0].place(f, false); doc.pages[0].rectangles[0].fit(FitOptions.FILL_PROPORTIONALLY); Now I want to move "thepdf" (which is of object type PDF) but I can only find a way to move the rectangle around it. I need to move the inner rectangle (the PDF), like I would do with the Direct selection tool. is this possible?
Yes. That's possible.
The PDF placed inside the rectangle is the graphics[0] object of the rectangle.
Or, if you look it up in the links collection, the parent of that link. The parent of that parent is the container object, the rectangle.
myRectangle.graphics[0].move(/*insert your arguments here*/)
Would move the PDF inside. Where the move() method could have different arguments:

Drawing lines, rectangles and circles as objects onto a JPanel.
Hi. I have to complete a task in school. The work is to create some simple 2D graphical editor. I'm new to java and I have some problems with this job, so I'm looking for help where it is possible...
I created a JFrame and using it as a window. Into this JFrame I've added a toolbox (JToolBox) and "drawpad" - a JPanel. The toolbox wasn't any problem, but I aim to use the JPanel for drawing 2D objects. I tought about creating some container of objects, where I could put lines, rectangles or circles, each one with its properties (color, [x; y] coordinates on the scene, filling and drawing width) and then, draw this scene onto the JPanel.
It should be something like windows Paintbrush. Can be simplier, but including the possibility to move and change properties of drawn objects.Well, there are two approaches to this that come to mind:
1. Create an image. If this program is supposed to be like Windows Paint, the tools you are describing are only there for the sake of modifying a two dimensional image. In that case, I would recommend using a BufferedImage.
The JPanel can contain a single JLabel. The JLabel is constructed in the following fashion:
JLabel image_label = new JLabel(new ImageIcon(bufferedImage));...where bufferedImage is the image on which you will be storing the data. You can use bufferedImage.getGraphics() to get an object which will quite happily draw geometric shapes for you. Then, after each draw, you tell the panel to repaint itself.
2. Store the shapes and create a component to draw them for you. You'd create a new JComponent class that would accept objects representing geometric shapes. You then override the paintComponent method on this new class to have it render itself according to the contents of the geometry objects. It would also probably be advisable to have all of these classes implement a common interface (which you would also create) so the rendering component could treat them identically. -

I can't get my ipad4 to find my Apple TV box, I where do I find the little rectangle box with a triangle in it that I click on my MacBook Pro to turn on the appletv?
Welcome to the Apple Community.
Try the following steps, check whether things are working after each step where appropriate, before trying the next.
Check AirPlay is turned on on the Apple TV (turn it off and on if it already is)
Check that both devices are on the same network (Settings > Wifi, on the mobile device and Settings > General > Network, on the Apple TV).
Restart the Apple TV (Settings > General > Restart).
Restart the Apple TV by removing ALL the cables for 30 seconds.
Restart your router. (Also try removing it’s power cord for at least 30 seconds)
Restart your mobile device. -
This has happened on the last few versions of firefox, as long as canvas has been supported. I see other people's screen shots from canvas tutorials, and the text always looks normal. On my system, any text put into a canvas element via context.fillText() will have a black bounding box for each letter, sized appropriately for the letter. If the text is black, of course you only see rectangles. If the text is a contrasting color, then you can read it, but it looks bizarre.
Thomas...same kind of crap here.
I used Custom Text - entered a sentence, hit return, entered another.
Set to 72 pt.
The default alignment is centred - I want left aligned text...the text start point stays at the centre of frame and the sentence runs off the edge of the bounding box.
There is no settings in the Text or Title inspector dialog to correct that!
Using Transform will not sort it! -
How to Trim Rectangle with text to create reflection?
Hello Everyone,
I am realtively new to Illustrator and I am facing a problem that I am hoping some expert here can resolve. I have some text and I have converted it to outlines. Now I want to create shine on it. I want to fill a rectangle with white color and then clip it with text to give reflection effect but I can't figure out how to do it. I have selected my text and rectangle and tried all options in path finder tool but nothing seems to work. Please guide me how can this be done.
Regards,
Afraz AliAfraz Ali,
If you want to have the colour/colours/colour transition of the rectangle where the text is is nothing outside it, in other words colour the text with the colouring of the rectangle, you may:
Use Live Type over the rectangle, select both, and Object>Clipping Mask>Make.
With outlined type, you have to turn the lettershapes into a Compound Shape first.
As you can see, it is simpler to just use Live Type, and it is editable. -
How to use the Rectangle class to draw an image and center it in a JPanel
I sent an earlier post on how to center an image in a JPanel using the Rectangle class. I was asked to send an executable code which will show the malfunction. The code below is an executable code and a small part of a very big project. To simplifiy things, it is just a JFrame and a JPanel with an open dialog. Once executed the JFrame and the FileDialog will open. You can then navigate to a .gif or a .jpg picture and open it. What I want is for the picture to be centered in the middle of the JPanel and not the upper left corner. It is also important to stress that, I am usinig the Rectangle class to draw the Image. The region of interest is where the rectangle is created. In the constructor of the CenterRect class, I initialize the Rectangle class. Then I use paintComponent in the CenterRect class to draw the Image. The other classes are just support classes. The MyImage class is an extended image class which also has a draw() method. Any assistance in getting the Rectangle to show at the center of the JPanel without affecting the size and shape of the image will be greatly appreciated.
I have divided the code into three parts. They are all supposed to be on one file in order to execute.
