I need to display a large number (500+) of small circles on a form to simulate LEDs. However, these circles need to be quite small, around 8 or 9 pixels diameter. So far, in my testing, I've put together some code that creates an Led class that uses a Shape (Ellipse2D.Double) and displays it directly on the JFrame from the JFrame's pain...
This is a question regarding the JNA library in a Java program. I have a tray application. "JFrame 1" is loaded at start of program. "JFrame 1" has a custom shape and has transparency. (Custom shape = ellipse) It works on Windows, Linux and Mac OS X. BUT! When I open "JFrame 2" (a normal JFrame without custom shape and transparency), ...
I want to assign a ComboBox control to a class member of ComboBox type. This control is in a group on a worksheet. The problem is through GroupItems property, I can only get a Shape object, not a ComboBox. So when assigning, it alerts "type dismatch". If the control was not in a group, I could get an OLEObject object through OLEObjects...
I'm creating a custom progress bar (positioned under a WebView) and what I would like to draw is a 1dp-wide line between the WebView and the ProgressBar. I'm modifying existing drawable, namely progress_horizontal.xml, and tried something like this: <?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android...
I'm looking for a shape recognition tool for Java. In particular, I'd like to find a Java library that given an image file (in jpeg, bmp, gif or any common image file format) gives me information about the regular shapes (rectangles, lines, ...) found in the picture and their coordinates. In previous questions on this topic I've seen r...
Is there any way to draw text in a DisplayObject or Shape using only ActionScript? The only way I can find on the web is by creating a TextField, but I can't add a TF to a DisplayObject or Shape. Edit: Solved thanks to viatropos. For anyone that's interested: DisplayObject implements IBitmapDrawable which can be passed as an argument...
In my XNA game, I needed to define an irregular shape based on several Vector2 coordinates in the 2D space. The reason was to do collision check (like Rectangle.Intersects()). For example: Vector2 point1 = new Vector(20,30); Vector2 point2 = new Vector(60,30); Vector2 point3 = new Vector(60,80); Vector2 point4 = new Vector(40,90); Vect...
I am working on a on-screen keyboard for Android, and I need to recognize starting points, turning points and end points of lines drawn by the user on the keyboard. A simple straightening function would be nice, as it is difficult to draw a perfectly straight line even with a stylus, not to mention finger-only touchscreens today. What I...
I have two questions about java.awt.Shape. Suppose I have two Shapes, shape1 and shape2. How can I serialize them in some way so I can save the information to a file and later recreate it on another computer? (Shape is not Serializable but it does have the getPathIterator() method which seems like you could get the information out but ...
Another WPF question... <UserControl x:Class="TKEApp.Components.UserControls.ButtonControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Grid Background="Black"> <TextBlock Foreground="White" Background="Brown" Name="lblCaption" TextAlignment="C...
I would like to write a T-SQL statement, that structures data to be loaded into a Ado.Net DataSet like it was possible with the ADO SHAPE command. Is there something similar in T-SQL? My idea is to select multiple rows from a main table and all related records from a child table. That data would get loaded in to a DataSet and then I wou...
Hi, I'm new in Image Proccessing. I have an image and I want to parsing Text blocks and picture blocks. How can I do? I don't use OCR components. I need algorithm or sample or suggestion. ...
I have the following code: <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="line"> <stroke android:width="1dp"/> <size android:height="1dp" /> <solid android:color="#FFF"/> </shape> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" ...
Hi there, my name is Daniel and I'm from Spain. I am developing a small program which cuts images by the color. That's will be easiest to explain using an example image. I have got this image: http://dl.dropbox.com/u/944667/Ejemplo1.png And I want to create a new image just with the purple form, without the black frame. Does anyone ...
Hello, I have some kind of a shape consisting of vertical, horizontal and diagonal lines. I have starting X,Y and ending X,Y (this is my input - just 2 points defining a line) of each line and I would like to make the whole shape scalable (just by changing the value of a scale ratio variable), so that I can still preserve the proper con...
Hi All! I'm trying to apply a linear gradient to my ListView. This is the content of my drawable xml: <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"> <gradient android:startColor="#3A3C39" android:endColor="#181818" android:angle="270" /> ...
Hello, I need to display a text in 3D using vml/canvas/svg and do some transformation to the shape of the text like the effect of Ctrl+T in photoshop, even align a line of text to a curve. For example, transform a normal text to a rotated, trapezoid/quadrilateral shape. So, is there a way to convert text to shape first? The only thi...
Here is the site I'm currently working on: http://willcrichton.net/ If you click on the arrows on each side of the hexagon in the middle, you can see that it transitions left and right using jQuery + jQuery Cycle + jQuery Easing. However, you can also see that it is rather ugly -- because I'm using hexagons and not squares and because d...
I'm wondering how vector drawing in Android with the Shape class may resemble another vector drawing standard. Since Shape is a Drawable, and Drawables are usually defined as XML, it sounds a lot like the vector drawing commands in SVG. My question is this: Has anybody created an XSLT transformation, or other mechanism, for converting ...
I want to have a elmenent with a 2 color border outline. I can do a single color outline using the element, but this only allows me to draw a single line. I tried using 2 elements within my but that didnt work either. Is there a way to either draw a shape within a shape or draw 2 lines around my shape (which has rounded corners b...
