How to make a transparent canvass?

does java supports a transparent canvass or a transparent panel?

The component which is embedded in html can't be transparent - this is not a java limitation, its just a limitation of all browser plugins.
However inside of this area you can use e.g. transprent JPanels, SwingX has some nice components which support translucency.

How to make treetable transparent

hi,
Does anyone have idea how to make the treetable transparent so that the background image can be shown?
Pls provide sample code if possible,thanks!

I don't know if I can come up with some code example
for you since I don't know what treetable your are
using... but... Transparency is always going to relate
to the whether your components are opaque or not.
Opaque = Not Transparent, so setting opaque = false
will hopefully make your table transparent. You may
need to do this on your CellRenderer's as well.
Hope this helps,

hi,
i am using JTreeTable provided fron Sun swing connection article,by Scott Violet and Kathy Walrath.
The situation i am facng now is jtree able to be transparent, but jtable still using it default background.
Below are excerpt from sample, setOpaque(false) to jtable seem doesn't take effect.
As i an newbie to swing,kindly point out where part shd i modified on the code. Thz!

* An editor that can be used to edit the tree column. This extends
* DefaultCellEditor and uses a JTextField (actually, TreeTableTextField)
* to perform the actual editing.
* <p>To support editing of the tree column we can not make the tree
* editable. The reason this doesn't work is that you can not use
* the same component for editing and renderering. The table may have
* the need to paint cells, while a cell is being edited. If the same
* component were used for the rendering and editing the component would
* be moved around, and the contents would change. When editing, this
* is undesirable, the contents of the text field must stay the same,
* including the caret blinking, and selections persisting. For this
* reason the editing is done via a TableCellEditor.
* <p>Another interesting thing to be aware of is how tree positions
* its render and editor. The render/editor is responsible for drawing the
* icon indicating the type of node (leaf, branch...). The tree is
* responsible for drawing any other indicators, perhaps an additional
* +/- sign, or lines connecting the various nodes. So, the renderer
* is positioned based on depth. On the other hand, table always makes
* its editor fill the contents of the cell. To get the allusion
* that the table cell editor is part of the tree, we don't want the
* table cell editor to fill the cell bounds. We want it to be placed
* in the same manner as tree places it editor, and have table message
* the tree to paint any decorations the tree wants. Then, we would
* only have to worry about the editing part. The approach taken
* here is to determine where tree would place the editor, and to override
* the <code>reshape</code> method in the JTextField component to
* nudge the textfield to the location tree would place it. Since
* JTreeTable will paint the tree behind the editor everything should
* just work. So, that is what we are doing here. Determining of
* the icon position will only work if the TreeCellRenderer is
* an instance of DefaultTreeCellRenderer. If you need custom
* TreeCellRenderers, that don't descend from DefaultTreeCellRenderer,
* and you want to support editing in JTreeTable, you will have
* to do something similiar.

How to make jframe transparent?

Hi
some software's uses the monitor as a whiteboard to draw or to type text. How is this possible? I mean i thought that by making a jframe (full screen) transparent we should be able to do this? Is my understanding right? if so how to make the jframe transparent? when jframe is transparent will we be able to draw on it?

Try this:
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override public void run() {
JFrame f = new JFrame();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setUndecorated(true);
f.setBackground(new Color(0,0,0,0));
f.setExtendedState(JFrame.MAXIMIZED_BOTH);
f.add(new JComponent() {
@Override protected void paintComponent(Graphics g) {
g.setColor(Color.BLUE);
((Graphics2D)g).setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
g.fillOval(0, 0, getWidth(), getHeight());
f.setVisible(true);

Spherical Photo Gallery how to make a transparent background

http://www.flashandmath.com/flashcs4/spheregallery/index.html
http://www.flashandmath.com/flashcs4/spheregallery/spherical_gallery.zip
I am pretty new to the world of flash, a flash newbie.
Please check link above my question is related to making this sphere gallery.
I am trying to make the background transparent, and i can , when i make it transparent
the navigation for the sphere doesnt let me navigate throught the pictures.
If you look at the code i made it transparent by removing the drawboard function or the fills in the function.
As i said when i do this the navigation seems non functional.
if download link does not work try the other at the top.

Hi,
Since you had written event handlers on 'board' and board is transparent (without drawBoard function), there will be no events triggered and navigation is not possible. Workaround is to create board with fill = minimum alpha value (0.01).
board.graphics.beginFill(0x0, 0.01);
Let me know if you need more information.

Karthikeyan R.

How to make a transparent java applet?

is it possible to make a transparent applet?

No. But consider making the applet paint a background that matches (in colour and texture) the background of the web page in which it's being displayed.

How to make a transparent header?

Hello everyone,
Im a beginner in photoshop, so excuse me if this is not a very smart question.
I did a bit of editing with the header on the site http://www.amazingplacelist.com but i want to make the header a little bit transparant.
Is this possible and how do i achieve this/wich settings do i use in photoshop?
thank you!

Hi there
It would be helpful if you could post a screenshot of your layers panel if that is possible. However, I've posted a few tips below on using opacity with layers.
Below is the layers panel for my re-creation of your image. It may not look similar to your layers panel, but if you'd like, I can provide instructions for how I created my image. Essentially, I have a colored background layer, the island image with an opacity mask, and a basic text layer.
To change the opacity of the island, click on the thumbnail of the image in your layers panel. In the top right area of the layers panel (shown below), there should be a slider labeled "Opacity". This will allow you to change the transparency of the image.
Now, since you're using this image on a website, it will be helpful to use Photoshop's Save for Web function. Choose File > Save for Web... from the menu bar.
This function will allow you to save images for use on the web, and will also allow you to preserve any transparency. Note that below I've selected PNG as my file type and checked the box for "Preserve transparency".
I hope this helped you out, if you need additional explanations or instructions, please don't hesitate to ask
Good luck!

How to make image transparent to background in Web Dynpro...

Hi Experts,
IN our web dynpro application, we need to have some fonts and sizes of texts to be displayed on the layout. Since web dynpro has limited options for the design and color of a Textview, we have decided to use the image instead.
This image has exactly the same background color as that of web dynpro and is matching perfectly.
But the problem is, it shows a border surrounding the image. We need to remove that border and make it completely transparent to the web dynpro background.
I have tried different design options for Image element but it did not worked.
Has anyone done this earlier..
Regards,
Anand

Thanks Nitesh,
I have downloaded the MIME image and it doesn't appear to have the border. This border is added by web dynpro application itself.
Regards,
Anand

Try setOpaque(true) and setBackground(new Color(r,g,b,a)) where r, g and b are respectively the values of red, green and blue and a the alpha value (0 means totaly transparent, 255 totaly opaque). Sometimes a component should be opaque with a transparent background to make the transcparency works.
But I have to ask you a question : have you bugs with the display ? Indeed, I made an app that doesn't use a gradient paint like you, but the JFrame have a ContentPane that display a picture. I made every JComponent transparent in order to see the background picture. The display is very dirty with JButton, JTextArea, JTextField and JList. Indeed, when moving cursor over JButton, the JButton displays the top lecft corner of the JFrame instead of the underlaying part of the picture as expected with transparency. With JTextField and JTextArea, when typing text the same problem occured. With JList, the problem appear when scrolling. only a full update(Graphics g) can clean the display, that is I must call it with every mouseMoved, mouseClicked, etc. events. The problem appears only with JDK > 1.2.2 (JDK1.3 and later)

How to make a transparent text layer over a photo that scrolls?

I looked through the Adobe Inspire Magazine, and found something really astonishing: the editor's added a text-over-photo effect multiple times throughout the magazine (See http://inspire.adobe.com/, october 2014. Has to be on the iPad to see the actual effect. "It's about the stories" by Dan Cowles features this effect).
I was really baffled to see it, as it fits my current project perfectly. I'm building a book about a recent trip to Iceland, which will be released for the iPad in the nearest future. So far, I have used Adobe InDesign CC to create pretty much the entire book, since I know little to nothing about programming.
My question is, how did they (he) do it?
Is it possible to do for someone with pretty limited knowledge? If it is, how can I do it?
Thanks a lot!

Since Adobe Inspire is made using DPS, then you can do everything that it does.
At the top of the help document, Digital Publishing Suite Help | Digital Publishing Suite Help, there are links to topics like Getting Started, Design and Layout, System Requirements, etc. Read them over to gain an overview. Also, download and review DPS Tips from the App Store.
If you are using Creative Cloud 2014, you should already have DPS Tools available to you. DPS is supported for InDesign version 6 and greater. I have found DPS pretty straight forward to use following the information given in the documentation along with help from this forum and DPS Tips.

Guided Access (how to make areas transparent rather than gray?)

I'm trying to use guided access so I can read while holding the iPad like a book = don't wish to have my thumbs changing the zoom and place I'm at in the trext...
When I set up Guided access for this and mark off regions for my thumbs they show up as gray regions which is annoying. Is there a way to make them clear, or even better another solution for this problem as guided access seems rather flacky at times. Thanks

How to make a transparent background for logo

I've tried creating a transparent backgound for a logo in Photoshop CS4 in numerous ways such as saving the file as a png and using the magic wand (text resolution was very poor) but neither worked. My logo has text and an image.
Any ideas?
Thanks.

I saved the file as a png and the background was not transparent--that is, it retained the white background. Please see the attached image for the pgn settings. In additon to a low resolution web version, I need to save a high resolution version for print.

How to make a transparent background

I have a design and i need the background to be transparent, as it is going onto a website asap.
I use Photoshop CS5 (64 bit).
thank you

Keep in mind that PNG-24 format is the only web-compatible format that offers partial transparency, which means that edges of things can be made to look smooth, not jaggy as with GIF in the general case, and you can do special effects like drop shadows.
Here's an example: http://Noel.ProDigitalSoftware.com/temp/TransparencyTest/TransparencyTest.html
