Painting background of transparent icon

I have an ImageIcon that came from a transparent gif. Is there a way to control how the background color is painted, for example setting the background to red or white? Thanks.

That's one way to do it but it may not be appropriate - eg the component may have an empty border, it may contain other content, it doesn't alter the icon when displayed elsewhere, etc.
If you want to cook a new icon then:
1. create an image of the same size
2. get the graphics object from it
3. fill the graphics with the chosen background color
4. draw the original image onto the graphics
5. create a new ImageIcon using this new image

How to paint transparent icon on component?

I am trying to paint a transparent image onto a swing component. The image is painted, but the transparent regions of the gif are painted as grey! How to overcome this problem?
class PrettyComboBox extends JComboBox{
ImageIcon imageIcon;
public PrettyComboBox(){
setOpaque(false);
this.imageIcon = new ImageIcon("transparentRegions.gif");
protected void paintComponent(Graphics g){
super.paintComponent(g);
imageIcon.paintIcon(this, g, 0, 0);
Any help or comments greatly appreciated!

Actually I've figured out how to make the combobox editable and also paint an icon. Now if only I could get the transparency of the icon working, I'd be set!
BTW the following code is how I use a ListCellRenderer in conjunction with an editable ComboBox, the trick is to set the renderer AFTER setting the combobox to be editable.
class PrettyComboBox extends JComboBox{
ImageIcon imageIcon;
public PrettyComboBox(Vector vec){
super(vec);
setEditable(true);
setRenderer(new ComboBoxRenderer());
setOpaque(false);
this.imageIcon = new ImageIcon("hasTransparentRegion.gif");
protected void paintComponent(Graphics g){
super.paintComponent(g);
imageIcon.paintIcon(this, g, 0, 0);
public class ComboBoxRenderer extends JLabel implements ListCellRenderer {
public ComboBoxRenderer(){
setOpaque(true);
public Component getListCellRendererComponent(
JList list,
Object value,
int index,
boolean isSelected,
boolean cellHasFocus) {
setText((String)value);
//add image to label, if desired
return this;
thanks for the comments!

Hi, i am really new to photoshop and i have a design which i need to have the background made transparent? can anyone assist please?

hi, i am really new to photo shop and i have a logo design which i need to have the background made transparent from a white square? can anyone assist please?
i have already got the image on my screen but cant seem to find the tool in which to make it transparent as i do with other softwares.

hi aknaloku,
is the background apart of your image or is the image on a different layer?
if the white background is on a different layer you can simply delete the layer for the layers window which you can find in Window>Layer. you will need to delete the background layer by dragging it into the little rubbish bin icon down the bottom right of the layers window.
i hoped this helped

Background-color:transparent !important; is not working in IE

Hi,
In my sharepoint site i have used "background-color:transparent !important;" css. It is not working in IE but in Mozilla is working fine.
And I am using IE 11. Please let me know is there any thing wrong in the syntax. If that is the case please provide me correct solution for that.
Any help would be greatly appreciated.
Regards,
Saya

Thank you for your reply.
I have checked given links. Those are not use for this issue.
Actually in my sharepoint site the same code "background-color:transparent
!important;" was working fine before installing sharepoint 2010 service pack 2. After installation we got this issue. And if i change "transparent"
with any color, it is applying that color. Only "transparent"
background css is not working in IE.

When inserting a .pdf of a document with a standard white paper color the test and images show up, but the white background is transparent. How do you also make the white paper color show up?

When inserting a .pdf of a document into a Keynote template with a standard white paper color the text and images show up, but the white background is transparent. How do you also make the white paper color show up?

Use the color fill option - select the inserted .pdf and assign a fill color of white to it using the Color Fill Menu on the Toolbar or the Color Picker Palette.
Good Luck.

I was having the same problem with a Tree Component. Just

tabs.menuContent is the path to my Tree, or your List
var mc = tabs.menuContent;
_global.styles.ScrollSelectList.backgroundColor = undefined;
mx.controls.listclasses.SelectableRow.prototype.drawRowFill
= function(mc:MovieClip, newClr:Number):Void {
mc.clear();
if (newClr == undefined) {
mc.beginFill(0xABCDEF, 0);
} else {
mc.beginFill(newClr);
mc.drawRect(1, 0, this.__width, this.__height);

Textarea ... background-color:transparent causing problem in IE7

is there a way to get a transparent background for a textarea such that the textarea functions correctly in IE7 ( I haven't tested it in IE8 )?

What happens if you remove the background tag altogether?
I do this with my overflow css for text boxes and it leaves them transparent (as in: showing the page background) in Firefox, Safari Opera and IE 5, 6, 7 and 8.

Imported SWFs background to "Transparent" in Presenter?

Is it possible to set an imported SWFs background to transparent within Presenter? I have Presenter 7, PowerPoint 2007, Flash CS4, working in Windows Vista.
The only way I know to set SWF transparency is with the WMode parameter... so, in PowerPoint, if I right-click the imported SWF and choose "Properties" I get the Properties window which contains a field WMode. I set this to "Transparent", but when publishing the Presenter file to "My Computer" the original SWF background (white in this case) still shows up.
My PowerPoint has a gradient background, and my SWF file's stage is smaller than my PPT stage. Making teh SWF BG transparent will allow me to place the SWF wherever I need to on the PPT stage without having to worry about lining up background gradients precisely.
Any help is appreciated.

So, not even 4 years later, and after 2 new versions of Flash can we still not produce a transparent background to be able to seamlessly go in a Powerpoint 2010 file? I imported a single/looping file under the <Insert Tab. It had a transparent backgound and a playhead with start/stop on it. Can't remember how I did it though?
Thanks,

Combobox background displaying transparent - help

I have 5 comboboxes in a form and I can not get them to react
to AS at all. In addition, their backgrounds are transparent so the
list is stepping on other information underneath it - making it
unreadable.
I've tried setting a styleObj and attaching it and then
setting the style properties, but nothing seems to work. I'm in
Flash 8.
any help will be greatly appreciated.

The combo boxes themselves where the problem. They came from
another file and for some reason, they just weren't accepting the
setStyle. I deleted them and dragged in new components to the stage
and the new ones worked.

I posted before and got some answers, but tried everything and didnt work.
If it helps, I notice that something is dif when I check websites or write emails, like they are a bit shaky when I move the cursor over it, or write an email. Maybe that has something to do? some graphic issue?
HELP HELP HELP!!!

jaykay, the first thing i try with the "transparent" itunes is updating the DirectX on the PC. if no joy with that, try making sure that the video drivers on the PC are up to date.
the following document is on sound issues, but down the bottom it has good links on updating both DirectX and video drivers:

Dark blue background and weird icon placement on jump list (recent files) of apps in task bar

Hi, I recently made a factory reset of W8.1, and now I'm seeing a weird and very annoying dark blue backgound in the list of recent files that appears when you right click an app pinned to the taskbar. Also, the "pin to taskbar" and "close window" icons show sort of out of place and apparently larger than normal I've tried looking through every possible setting but I can't find anything related to this list in particular. Any ideas?
Thanks in advanced.

Hello @Adrianrff, I understand that a dark blue background and strange icon placement on the jump list of apps in the task bar of your computer, and I would be happy to assist you in this matter! Since this issue occurred after performing a factory reset, I suggest performing a full system recovery by following the steps in this resource on Backing Up Your Files (Windows 8), as well as Performing an HP system recovery (Windows 8). This should return the jump list and icon sizes back to factory settings.
If the issue continues, please contact our technical support for further assistance in this matter by clicking the link below to get the support number for your region.

I hope this helps!
Regards Thanks for the suggestion, MechPilot. I did a full system recovery but unfortunately it did not work. Apparently the color of the background matches the color chosen in Windows first startup, but I don't remember having chosen white the first time, everything looked fine then. Any other suggestion?

Transparent Icon - Can't Open

I'm running OS version 10.2.1.2141. I installed "Backgrounds (OGQ)" app from the 1Mobile Market. When I try to set a picture as a wallpaper, and choose the "Backgrounds" app to do so, it is able to set my new wallpaper. As soon as I set it as my wallpaper, I'm sent back to my home screen and the "Backgrounds" app goes to the active frame section. When I close the "Backgrounds" app and then go to find the app icon for it, it appears transparent (just like when you hold your finger over any app icon). I can't open the app when it's transparent. I've tried closing the app under "device monitor", but that doesn't reset the app. So far the only solution has been to reboot the phone.
I know this "Backgrounds" app is not native to BB OS; but is there an alternative solution to this?
Thanks

Have you tried deleting the app, rebooting and reinstalling?
It could just be that app is not going to be compatible.
