Drawing of objects

Hello!
I am a german student and I have the following problem.
I need to draw a connected directed graph onto a panel. Therefore I created a class that represents the nodes of the graph. Each object has a pair of coordinates (all coordinates are located on a circle) and a paintComponent-method that works with the graphics-context of a panel where all objects should paint themselves on.
In the moment I have to check for every MouseEvent performed on the surface of the panel whether the clicking occured in the area of one of my objects, that is i have to run through all objects even if the user clicked the panel somewhere else.
It would be best if I could handle the nodes of my graph as single components, each equipped with its own ActionListener. I am sure that it must be possible to work things in that way, cause otherwise I cannot imagine how to realise drag-and-drop applications while editting graphes.
Perhaps someone can help me.

Thanks, and bugger! I had no idea Smart Guides were changed that much - if it ain't broke, why fix it?
I've now read somthing about pressing teh shift key will bring up movement alignment in 45 degree increments. Pretty clumsy, as I often have the Alt key pressed as well when copying objects accross severy layers. I have Shift and Alt as the two buttons on the pen of my Intuos pad - I don't think I can press both at the same time (and even if I could it just makes things really awkward)...
Oh and btw. when I asked the question I wasn't aware that I was on a user forum - I thought I was writing to Adobe's customer service team! They did really well at disguising the path of getting in touch with them and thus making you guys do the work for them!
So sorry for not having much of a forum ettiquette in my very first posting.
Cheers

Adobe Flash CS5.5 Crashes while drawing/dragging objects.

I have experienced quite a few crashes trying out Adobe Creative Suite CS5.5 Premium when it comes to using Flash Professional CS5.5. I have documented one of the crashes at a pastebin entry, which I will link it and an earlier crash log dump below.
Here's how the crash occurs on my iMac (27-inch, Mid-2011 with AMD 1GB Dedicated Graphics):
1.) Create either a Flash Document - AS 2.0 or AS 3.0 does not matter, though using 3.0 makes it crash faster I've noticed.
2.) Draw shapes. After a while of drawing shapes and making them into groups/objects/symbols...
3.) Drag the shapes around, eventually performance starts to drop over time.
4.) After a while, Flash will freeze and crash, complete with the beach-ball spinning.
The most recent crash:
http://pastebin.com/YCWKAbhp
There is my pastebin of my latest crash, using an Adobe Flash document using ActionScript 2.0.
Alternatively, sometimes Flash CS5.5 will crash using ActionScript 3.0 as the language of choice, and oddly much quicker. One of those crashes can be found here: http://pastebin.com/pTSerErw
The irony in both cases is I don't primarily use Flash Professional CS5.5 for programming or scripting at all. I use it for basic vector artwork for an array of projects. Thus, I don't use AS3.0 with this program.
Here's what I have done so far to try to remedy this:
I have updated the Apple JRE/JDK for Mac OS X Lion to the latest revision. I also have cleared out the JRE/JDKs and have started from scratch, to clear out any possible mistakes in installation. I know Java seems to be part of the Flash complilation process, oddly enough
Use ActionScript 2.0 documents helps keep crashes down, oddly. Yet they still happen eventually
Booted into Safe Mode to try to fix permissions and such. No dice
Repaired permissions manually using Disk Utility. No dice
Edited my jvm.ini file on my install to have no memory constraints, instead defaulting to the ones I have manually set for my JRE/JDKs. Specifically for my Java 64-bit JRE/JDK: -Xmx2048m -Xms512m -Xss2048m -d64 using the Java Preferences application in /Application/Utilities/
I have also monitored the console for any activity aside crashes. No dice
Trashed my Preferences and Application Support files
Deleted/Fixed corrupt or duplicate fonts - I did find some duplicates due to Microsoft Office 2011
I also have sought out other errors here on the Adobe Forums/Community. While similar, they are usually for more complicated projects, while mine is simply drawing and copy/pasting stuff seems to be a problem.
In short, I've done my research and still haven't been able to fix it
Oddly enough, most of the time no corruption has been reported due to this. In fact, I usually just have to restart Flash, save often, and if it crashes, repeat until my project is done. I also don't use auto recovery because it actually makes things more confusing and I admittedly don't trust it.
Also, I usually have Flash Professional running, as well as Adium (IM client), Safari, and iTunes. Usually no other programs are running outside background programs or menu bar items.
Does anyone have insight, solutions or possible pointers on how to fix this? It's more of an annoyance - but this is painful since I spent good money on this product. I hope CS6 improves this with full 64-bit support and better memory management.

Hi,
I am not sure if this is a "Master Page since we use a French version (the functionnality is named "Gabarit" in French), so here is a printscreen which shows what our users try to do:
Immediately after the drop is completed, InDesign shuts down without further notice as described before.
I fully patched one machine to 7.5.3, rebooted it and it still does not work.
I know 2 GB is a little bit short, but since this is currently a corporate standard in my customer's organization, I will need to be sure that this is the direct and only cause before any upgrade request can be made.
Thank you for your help.

Precise movement and drawing of objects in CS6

Hi,
having used CS3 before, I've recently bought the CS6 package. I set all Preference settings they way they were in CS3 but I'm having difficulties moving a selected object in precise orthogonal (or diagonal) orientation. I'm used to seeing an "origin" alignment aid when I drag the object, usually at 0, 45, 90 or 180 degrees to its original position. This doesn't happen anymore in CS6, instead I get a myrad of alignment options to any other objects of anchors in sight, but not the important "origin" one. The same problem exists with the rotation tool - when I want to rotate an object quickly by 90 or 180 degrees, in CS3 I could just use the rotation tool and it would "click" into origin positions at 90 or 180 degrees. In CS6 I get an small window showing me the exact rotation degree, but to me it's pretty useless to know that I've just rotated the object by 179.6 degrees, but I can't get to the exact 180.
I am aware that I couold always use the Transformation option and enter a precise value of either moveemnt or rotation, but for simple actions it was much quicker to use a select and drag or select and rotate tool.
The pen tool is slightly better with the "origin" alignment aid, but still I get a lot more unwanted alignment options than before in CS3, distracting from quick and precise positioning of anchor points.
I do a lot of quite technical drawing, more akin to CAD than "free" illustration, but never had such a problem with Illustrator in CS3.
Is there a way to set up CS6 so it behaves the way I'm used to?
Best regards

Drawing small objects?

I'd like to be able to draw a disk of 2 mm diameter quickly.
I'm working on MacOS X 10.4.11, and in my environment,
the decimal separation character is the ",". Hence, for example,
2 and a half inch is written 2,5".
I proceeded as follow:
• open Pages'08 (version 3.0.2) which will open a blank page;
• select Shapes > disk (from the Toolbar) which will drop a green disk of 3,53 cm x 3,53 cm;
• select the down right handle of this disk with the shift key pressed;
• move this handle upside left to reach the desired value: 0.2 cm.
First problem:
I can't reach the 0,2 cm value.
I'm able to reach 0,21 cm and 0,18 cm.
Second problem:
I opened the Inspector > Metrics
I tried to type 0,2 cm in the Width field, but the only result was the
bong! from the speaker.
I tried to type 0.2 cm ("." in place of ","), but the field value was replaced with 2 cm, and the disk resized to 2 cm.
Did I do something wrong?
I have the exact same problem with all the small objects I want to create.
I simply can't draw them quickly.
I found a workaround: enter the Inspector > Metrics, *for each object*,
enter a size of 1,2 cm in the Width field, and then decrease it with
the scroll button on the right of the field, which does set it to
0,2 cm. I feel like trying to hunt flies with a hammer.
What is the direct and efficient method?

Daniel,
What you would like to do works well in my version of Pages and my language setting (US English).
Thank you for your different viewpoint. I tried to set my international settings (International > Input) to United states, and the second problem
disappeared. But the first one is still a serious problem biting me many times
per hour (I do a lot of graphics for technical documentation).
Until you find the answer to your difficulty with direct entry of the decimal character, you may find some convenience in creating an otherwise blank document to leave open on your desktop with the little circle in it. Then just Copy/Paste whenever you need it in your working document.
That's pretty much like the workaround I found. Once I have done one of my graphics, I try
to limit myself to copy and paste of the same one inside the same document
to avoid an unaffordable waste of time. Nonetheless, this method is a limit of
use of graphics and a huge waste of time.

Drawing InDesign objects on a extension panel

hi all,
I'm trying to develop an InDesign extension using the Extension Builder 2.1 – unfortunately I am almost completely new to the whole topic.
I was wondering if it's possible to draw objects, lets say a rectangle or a vector shape from an opened InDesign document to the panel. Actually it doesn't sound like a difficult task but anyway I'm a lost. I would appreciate any hint where to look for that concern.
Thanks for helping!

Hi,
Since you're new to the topic, I would start here: http://labs.adobe.com/technologies/extensionbuilder3/ (use Extension Builder 3, not 2.1).
Also, read this: http://www.adobe.com/devnet/creativesuite/articles/introducing-html5-extensions.html

Pen Tool - Curve drawing under Object Lock

How do you draw a smoother curved line as described in this tutorial in Steps 6 and 7?
http://design.tutsplus.com/articles/create-a-glowing-neon-sign-using-the-appearance-palett e--vector-3791

Thank you - As it turns out, I was using the tutorial here as a guide http://design.tutsplus.com/articles/create-a-glowing-neon-sign-using-the-appearance-palett e--vector-3791
I was trying to use Steps 6, 7, and 8 to draw lines with the Pen tool that traced the interior of letters to generate a neon sign effect to keep applying new strokes to build up the glowing effect.
I am having difficulty recreating smooth lines inside the trace of the letters – my lines look choppy and not at all like the tutorial suggests.
I was using the Appearance Palette, which stressed using simple paths that can be turned into vector artwork simply by using multiple fills and effects. The approach was to use the approach outlined to avoid having to use complicated Bezier curves or stacking multiple vector shapes on top of one another.

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.

Drawing objects in Flash

Help
When I draw to the stage using the line tool or pencil tool,
I am unable to fill the item with a solid color or gradient color.
You must be able to do it as most tutorials say "draw the object
using the line tool and fill it using the paint bucket"
What am I doing wrong??????

Need Help to Draw and Drag Triangle - URGENT

Hi everyone - I am developing various proofs of the pythagora's theorem
and the following code draws a triangle on screen and the proof follows -
but i need to know how to drag the triangle such tht 1 angle is always set to 90 degrees.
i.e. i need to resize the triangle by dragging its vertex points by which the1 angle remains at 90 no matter what the size.
The proof has got some graphics code hardcoded in it - i.e. LINES AND POLYGONS have been hardcoded
i need to reconfigure that such that everytime the user increases the size of the triagnle and clicks on next it draws the lines and polygons in the correct area and place
PLEASE HELP

THANKS

One of the problems you face is that it is hard to recognise which parts of your code are drawing the triangle. This is because you are writing code in a procedural way rather than an object oriented way.
In object oriented code you would have a triangle object that could draw itself. You would create the triangle object by specifying its sizes and angles in some way. Then it should be easy to change the triangles sizes and angles and ask all the drawn objects to redraw themselves.

Positioning moving objects

I'm getting ready to make a 2d game and wasn't sure how to draw moving objects on the screen. I've played around in the past and always had a fixed sized window and basically moved objects around on a pixel grid. I want to have a resizeable window but keep the relative size and movements of objects the same. How is this usually done? Should I just render it to the largest possible window size and then transform it to the appropriate size? Thanks in advance!

Should I just render it to the largest possible window size and then transform it to the appropriate size? Thanks in advance!Not sure what that means. Basically you have a couple options:
1- Store locations by ratios, not exact coordinates. So if you want a GameObject's location to be in the direct middle of the screen, its position would be (.5, .5). Then when you go to draw that GameObject, you have to convert that position to screen coordinates. You do this simply by multiplying the ratio-coordinates by the game window's width or height.
2- Store locations by some model coordinates. This is similar to the first method, but requires some extra translation. You would store the GameObject's location via coordinates such as (50, 50), but you would also have to keep track of how large your game window model was (for simplicity's sake, let's say it is 200 by 100):
drawPoint( (gameObject.getX() / 200) * gamePanel.getWidth(), (gameObject.getY() / 100) * gamePanel.getHeight() );Does that make any more sense?
Edit- I should say that there probably are a ton of other ways to do it, these are just the ways that most easily fit into my head. It's all just algebra though.

How do I create an offset outside (outside only) an object?

The problem is:
I often have complex vector objects which contain paths and I want to create a path around the object.
I have tried Offset Path, but this command also offset the interior of the object.
I have also tried Effect>Path>Offset Path, but the original path that I selected disappears and is replaced by the new offset path.
I want to keep the original path and have an offset around it.
I am a long time AI CS3 user and this question has always been lingering over my head.
My problem is that I create engravings of images and I want my machine to cut an outline around the engraving, the outline being X pts bigger than the engraving.
I have uploaded some images to help visualize the issue.
Thanks for any help.
P.S: I'm stuck with CS3 unfortunately.

Image with path that I want to offset: http://i48.tinypic.com/15xmsso.jpg
Image after offset: http://i47.tinypic.com/5nnind.jpg

Just to set up an example, draw these objects near each other:
A closed simple path (ex: Rectangle), solid fill, no stroke
A compound path (ex: two compounded circles, solid fill, no stroke
Duplicates of the above two objects, no fill, solid strokes of differing weights
An open path, no fill , solid stroke
Now carefully do the following to create an offset outline. Be aware, the resulting outline will take on the stroke/fill of the frontmost path.
For example, if the frontmost path has a black stroke, fill of none, so will the resulting offset contour.
1. Select all the Paths.
2. Object>Group.
3. Edit>Copy.
4. Edit>Paste In Front.
5. Effect>Path>Outline Object.
6. Effect>Path>Offset Path. Offset: as desired. Joins: Round.
7. Effect>Pathfinder>Add.
Now store this as a Graphic Style:
8. Black pointer: Drag the Group and drop it into the Graphic Styles palette.
9. DoubleClick the Style’s icon. Set its name to “Offset Contour” (or whatever).
Now you can apply the same Graphic Style to a different Group with one click.
Graphic Styles are saved with the document. So if you want to use the same Style in other documents:
10. Graphic Styles flyout menu: Save Graphic Style Library...
By default, the Graphic Style Library will be written into the Graphic Styles folder of your user account. Example:
C:\Users\firstName.lastName\AppData\Roaming\Adobe\Adobe Illustrator CS5.1 Settings\en_US\Graphic Styles
You can later load it into a new document by Graphic Style palette flyout menu>Open Graphic Style Library>User Defined,
or by simply copying a Group to which the Style has been applied and pasting it into the new document.
After storing the Style for future use, expand it into an ordinary path (or compound path, depending on the artwork):
11. Object>Expand Appearance.
12. Ungroup.
13. Apply fill/stroke as desired.
Once you have created the Graphic Style, you can record an Action to automate the whole thing, by recording these steps:
1. Steps 2-4
2. Application of the Offset Contour Style
3. Steps 11-13
Now you can create such an outline for any set of paths with a single click by selecting all the associated paths and clicking the Action.

Adding line-art shading to line-art object

I'm hoping that someone can give me an idea of how to do something a little easier than I have been doing. It's a little hard to describe but without an image upload function on this forum I'm going to have to try with words alone.
I am drawing simple line art (entirely vector) objects with solid colors that need a 3d look to them. For instance, a simple balloon where the right side is in the shadow, so it needs to be darker. If I were doing it with a pencil I'd just shade the right side of the balloon in a crescent shape. In illustrator though I need to create another vector object to be the shading.
The outside of the balloon needs to be a solid black line. The object that becomes the shading needs to have no outline because it's just a darker color of the balloon (e.g. dark red to the balloon's bright red color). Making the outline its own object can't be done because it will either not reach the line of the balloon or its own color will partially cover up the black outline (because it is in front).
I've been successful at making these by implementing the shading as a large object that intersects the balloon, creating a live object out of the two, then setting the various line segments and areas with the live paint tool until it looks right. However this is time consuming and I wind up with an object that is conspicuously larger than it looks because of the invisible parts of the live paint object sticking out. Also, if things get just a little more complex with additional live paint objects then there are a bunch of line segments and live paint areas that I have to take care of. Maintenance of the object is difficult.
Can anyone suggest a better way to do this that doesn't involve live objects, patterns/gradients (everything needs to be a solid color) and doesn't take a lot of work to create?
Thanks!

One way is the old fashion way:
1. Draw balloon object with highlight color, no stroke.
2. Copy balloon object, paste in front, reshape copy into crescent by dragging individual points from left edge toward right; recolor this copy as shadow tint.
3. Paste in front a second time, assign no fill, black stroke to this copy.

Illustrator CS6: Missing small pixels box that should follow the cursor when creating objects

Somehow I've managed to disable a feature in Illustrator CS6 that does two things: 1) it causes a small box to follow the cursor when I'm drawing an object 2) the light green lines or x's are gone now, too. How can I get them back? Are they only visible under certain circumstances? Thanks!
