How to make frames/panels transparent?

Say I wanted to have a window that had rounded edges, or a weird shape. Is there a way to create transparency on a frame so I can pull off this effect?

How to make a completely transparent button in Flash Builder

I am making a mobile application, and I am wondering how to make a completely transparent button. I've tried using
<s:Button x="-5" y="0" width="410" height="1504"
skinClass="spark.skins.mobile.TransparentNavigationButtonSkin" click="navigator.pushView(Sun)"/>
But it still has one line on the side. I need a way to make it completely transparent.
Thanks,
8th grade student

Try this alpha="0.001"
Also add useHandCursor="true" and buttonMode="true" if you wish to have the hand cursor appear on hover.
example x="10" y="10" width="169" height="54" label="Button" alpha="0.001" useHandCursor="true" buttonMode="true"

layout="vertical"
horizontalAlign="center"
verticalAlign="middle"
Then I use <s:Panel>,but I don't know how to make <s:Panel> middle both horizon and vertical. How to do it?

How to make the panel with scrollpane transparent?

Thanks Camicker for your help, it solves the problem but i got a new problem i.e. i want to make that panel with scrollbar transparent for this i have tried setOpaqe(false) for both scrollpane and panel but it doesn't work. do u have any solution?

I think camickr (not Camicker) already told you to set the opacity of the JScrollPane's viewport.
Spend just a few minutes with the JScrollPane API and you'll find an exploded view showing the components that make up a scroll pane.

Add your video component to one layer and your non-opaque panel to another layer.Did you try that with JMF? It does not work for me. As I said, the movie seems to draw itself always on top!

[iPhone] How to make one color transparent on a UIImage?

On my iPhone app I have a UIImage instance. I want to get a derived a UIImage that is the result of the first UIImage where one of its colors (e.g. magenta) is made transparent. How can I do this?
NOTE: I cannot make the color transparent in Photoshop, the UIImage is created on the fly by the user. I need to do the "postprocessing" on the phone itself, after the user is done "drawing" the image.

I still do not know your version of Premiere Elements and your computer operating system, but here is a plan that would probably work for Premiere Elements 11, 12/12.1, and 13/13.1 on Windows 7, 8, or 8.1 64 bit.
But you say that you are starting with a black and white image. If you could start with the color version of the image, I think we have a promising path to have the fake blood appear in color on a black and white image.
This would be done by applying the Color Pass effect to the color photo version. Color Pass Effect is found under fx Effects/Image Control/Color Pass.
Then you would edit the Color Pass effect under Applied Effects Tab/Appied Effects Palette/Color Pass Panel expanded. But I find that the most effective editing of that effect is done using the Setup whose icon appear to the right of the Color Pass Panel.
Have you used the Color Pass effect before?
https://helpx.adobe.com/premiere-elements/using/effects-reference.html
I will offer how to suggestion for its use if interested. As for starting with the black and white, then I need to think about that some more.

Anyone know how to make an "Index Transparent" gif

I have successfully made transparent PNGs and GIFusing an Alpha transparency but now I need to make images which would be the same as ueing fireworks / Photoshop to make a colour transparent. i.e. indexed transparency.
Does anyone know how to do this.
My code is as follows :
// configure all of the parameters
String text = "ABC abc XYZ xyz ["+ new Date()+"]";
String font_file = "./tst/Maiandb.TTF";
font_file = request.getRealPath(font_file);
float size = 30.0f;
Color background = Color.white;
Color color = Color.black;
Font font = Font.createFont(Font.TRUETYPE_FONT, new FileInputStream(font_file));
font = font.deriveFont(size);
buffer = new java.awt.image.BufferedImage(1,1,java.awt.image.BufferedImage.TYPE_INT_RGB);
Graphics2D g2 = buffer.createGraphics();
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
java.awt.font.FontRenderContext fc = g2.getFontRenderContext();
java.awt.geom.Rectangle2D bounds = font.getStringBounds(text,fc);
// calculate the size of the text
width = (int) bounds.getWidth();
height = (int) bounds.getHeight();
// prepare some output
buffer = new java.awt.image.BufferedImage(width, height, java.awt.image.BufferedImage.TYPE_INT_ARGB);
g2 = buffer.createGraphics();
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
g2.setRenderingHint(RenderingHints.KEY_ALPHA_INTERPOLATION, RenderingHints.VALUE_ALPHA_INTERPOLATION_QUALITY);
g2.setFont(font);
// actually do the drawing
Color transparent = new Color(0, 0, 0, 0);
g2.setColor(transparent);
g2.fillRect(0,0,width,height);
g2.setColor(color);
g2.setComposite(AlphaComposite.SrcOver);
g2.drawString(text,0,(int)-bounds.getY());
File file = new File ("./jsp1/tst/fred1.gif");

How to make opaque white transparent?

I have a JPEB, black words, hand lettered, on white.
When I place it into an InDesign doc, on a solid color, the white background, being opaque, covers the solid color.
How do I make that opaque white into a transparent background? Two manuals do not give me a clue.
Thanks.

No.. Photoshop transparency is automatically seen in Indesign for .psd files. All you need to make the background transparent in Photoshop.

You can group the controls as a Cluster and make a type-def of it. That's probably what you're after.

Well, the transparent part is easy. You should be calling setOpaque(false) rather than setOpaque(true). This will eliminate background painting of the JPanels.
The overlapping can be accomplished in multiple ways, but NOT using BorderLayout. You'll either want to do as one person suggested and use no layout manager and position things absolutely, or as another suggested and use JLayeredPane.
Personally, I would suggest a third approach that uses a single JPanel to do all of the painting. Something like this would work nicely:
public class DrawPanel extends JPanel {
    public DrawPanel() {
        setOpaque(false);
    public void paintComponent(Graphics g) {
        super.paintComponent(g);
        drawBase();
        drawGraph();
    public void drawBase() {
        g.setColor(new Color(0,255,0));
        g.drawOval(50,50,50,50);
    public void drawGraph() {
        g.setColor(new Color(255,0,0));
        g.drawOval(20,10,10,10);

Don't pay 300$ for that, just use JPanelThe OP specifically requested AWT, not Swing.

How to make Layers NOT transparent ??

Hey i am making an animation
Its of a guy walking but he is transparent. I have already got like 100+ frames of him walking but he is transparent and therefore i cannot put a background or it shows through.
Is there anyway i can make all existing frames nontransparent.

The easiest way is to create a new layer and fill it with what ever color you choose then when your ready for a new layer just duplicate that layer with ctrl-j or cmd-j (former is windows and later is mac)
