Change colors in the png - keep transparency

I load a png-file as ImageIcon into a JLabel as setIcon(). A color of the png (generally color white) is defined for transparency, that in the JLabel is represented correctly as transparency.
I want to convert now another dark color in ImageIcon like new Color (0,0,0) into a bright-grey-color like new Color (244,244,244), after the transformation transparency effect should kept by color white.
How can that be done, please?

BufferedImage is the easiest interface to the pixels yes. You can always load your images as BufferedImage instances and pass those to your ImageIcon objects; if you ever want the image back you simply cast the return value of ImageIcon.getImage() to BufferedImage.

I need help highlighting an expiration date on my Numbers '09 spreadsheet. I want the text/fill of a cell to change color when the expiration date of an item is within 180 days of the current date.

I need help highlighting cells on my Numbers '09 spreadsheet. I want the cell text/fill to change color when the date is 180 days or less from the current date. I already have a cell with the current date in it. I also know how to change the fill/text colors. All the cells have been formatted to show date only. I am having trouble with the formula. I can get to the Conditional Formatting menu and select "With Dates" but after that I am lost. Can anyone help?
Thank you for any assistance.

Set a Conditional Format rule as shown in the illustration below. The rule has been applied to all dates in column B of the table.

I am unable to change colors. The boxes stay grey. Can anyone help?

When entering text on a photo I can't change colors. I am unable to change colors with the bucket or brush. Any ideas?

You can try resetting your iPhone. Make sure to make a backup of your data.

Using the retouch tool, how do you make it change color? The old iPhoto one did, this one seems to be flesh-tone only, which is not how I need it to be. In old iPhoto, used the local color to blend, it was great.

I don't know which old version you're referring to but iPhoto 6's, 7's and 8's retouch tool works exactly the same as iPhoto 9's. The color of the enhance tool's area while applying is a light brown color but the retouch works on any color using the surrounding colors as a basis.

Change colors in the calendar

I saw that there is the possibility to change color to present a variety of calendars.
My webcal in particular should be on existing services WEBCAL, eg, the lunar calendar.
I change color, but every time my iPad or iPhone sync, returns the default color!
What can I do?

Yep, I just noticed this behavious on my iPhone 4 as well. Built-in calendars ("On My iPhone") stay locked in their colours, but subscribed calendars keep changing theirs. It's quite annoying.

Change color of the showDetailItem in panelTabbed in 11G

Dear All,
I have to change the color of showDetailItem in panelTabbed from gray to dark blue. But when I am trying to set the color from style the color of whole panel gets changed. I want to change the color of of the tab only.
Please help its Urgent.
Thanks in advance.

I was having this same problem, and found another issue with the scroll bar coloring. The ScrollBar.thumb UI property cannot use a color that has a reduced alpha value.
I wanted the JList hightlight and JScrollBar thumb to be a lighter version of the background color, but I found that the color.brighter() method returns a color that does not necessarily match the original color very well. For example, if you call it multiple times, the resulting color can be completely different. If I constructed a new color by lowing the alpha value of the original color (using the code below), the JList highlights were perfect, but the JScrollBar thumb had a large black "blob" in the middle of it.
Color c = this.getBackground(); //"this" refers to a JPanel
Color cb = new Color(c.getRed(),c.getGreen(),c.getBlue(),50); //alpha value of 50The only way to get rid of the black "blob" on the JScrollBar thumb, is to use the following line of code where you set this property:
UIManager.put("ScrollBar.thumb", new ColorUIResource(cb));Unfortunately, the ColorUIResource object does not appear to support altering the alpha value, so it strips it away, leaving you with the darker version of the color (completely negating your efforts to lighten the color).
Does anyone know how to resolve this issue?

How to change color of the caret (text cursor) in a TLFTextField used for input.

This might be a very simple Question, but I have looked and searched everywhere and don't find how to change the color of the caret in a input TextField.
any ideas?

This was driving me crazy, too--and the previous answers did not seem to work. I eventually found that if I click one of the data symbols in the graph in exactly the right spot (see below), it selects only the data symbols and not the line. I can tell this because the little selection dots will be around each data symbol, but no selection dots will be on the line between the data symbols - like the graphic in Yvan's answer. Then and only then will the color symbol in the tool bar show the color of the data symbol, instead of the color of the line. I believe that you then have to first click on the color swatch in the toolbar and then select your color (or choose Show Colors and select from the color tool). Just clicking a color in the crayon box, for example, did not seem to work unless I first clicked on the color swatch in the toolbar, then clicked Show Colors on that dropdown, and +only then+ clicked the crayon or whatever.
_The right spot to click_ seems to be just above the exact center of the data symbol, at least for the diamond shape symbol that I prefer. Sometimes it takes several tries to hit the right spot. If I miss it, the whole line is selected, which is indicated by the little selection dots on the line, between the data symbols. When I click the right spot, those selection dots go away, leaving only the data symbols selected. Then I can change the color, as described above.
I hope this works for you too.

Is it possible to change color on the line strip/code view in CS6?

Hello -
I did some research on this and cant seem to see if this can be done - I was hoping to change the color of the blue line menu on the code view screen.
Eric

I take it you're referring to that vertical line in the left hand side of Code View? I don't think it's possible to change the color. If you disable line numbers (#), it's a bit less noticeable.

Change color of the scroll bar?

I am trying to turn my entire application black with white or some light colored text.
Is there some way I can change the color of the scroll bar?
Also, if I have a JTable, there is a bright grey border I would like to dim down a bit.
Any guidance would is appreciated.

Hi,
This code will show you the current UI settings.
If you want to change ie. the scrollbar background use:
UIManager.put("Scrollbar.background", your Color);
Hope this helps.

Changing color on the title bar

How can I during runtime change the color of the title bar? I want to flash the title bar to warn, but I haven't found the function to set the color of it yet...
Thanks in advance!
Regards,
Andreas

since 1.4 you can use
JFrame.setDefaultLookAndFeelDecorated( true );
JDialog.setDefaultLookAndFeelDecorated( true );to get jframes and jdialogs looking like jinternalframes. but i don't know if it is now possible to change the color.

/* Autopacman spelletje
Menno Hagens, I108
2001
Autopacman.
Maak via overerving van de klasse Packman uit week 4 een nieuwe klasse 'AutoPackman'.
Deze klasse moet de volgende extra functionaliteit bevatten.
De kleur van de Packman moet kunnen worden ingesteld.
Er moet een methode komen die een willekeurige opdracht aan de Packman geeft.
(naarLinks, naarRechts, gaSneller, gaTrager, etc.)
Maak vervolgens een applet met vier Packmannetjes en ��n knop 'Beweeg'.
Als je op deze knop drukt, moeten alle Packmannetjes ��n stap in een willekeurige
richting doen.
Programmeer dit efficient met arrays en loops.
Als je na afloop nog moed hebt kun je de klasse en de applet zo aanpassen dat een
spel ontstaat, waarbij een Packman die op de positie van een andere komt, de andere
Packman opeet. Degene die overblijft heeft gewonnen.
