Converting string to color

I have a String str = "red" . how do i convert this to Color.red .

Hmm... I see two possibilities..
1. You make a Hashtable with entries like this:
      hash.put ("red", Color.red);
      hash.put ("blue", Color.blue);
      //etc. etc.2. You take a look what reflect can do.. ;-)
(java.lang.reflect)
I'd suggest the thing with the hashtable; it's easier and faster. :)

Converting Strings to Color Objects

Greetings All -
I'm in my first Java class (I was a C programmer in the 80s!) and am a little stumped on an assigment. Your help will be much appreciated.
I have to read color strings out of an HTML file and put them in a HashMap (a small applet assignment). I've been unable to find an elegant method for converting from a string to a color object.
Please let me know if I'm stuck with a big nested if or am I overlooking something?
Thank you -

This will handle #rrggbb strings, and also the dozen or so colors defined by name (red, cyan, etc) in the static fields of java.awt.Color:
static Color stringToColor (String s)
     try {
          return Color.decode(s);
     } catch (Exception e) {}
     try {
          return (Color) Color.class.getField(s).get(null);
     } catch (Exception e) {}
     System.out.println("bad color string: " + s);
     return null;
}

How can i open the "Convert to Indexed Color" dialog with custom presets?

Hi,
I need to automatically open the "Convert to Indexed Colors" dialog in Photoshop. Before and after that i have some scripts running so its not possible to open the dialog manually. Also i want to set some custom presets (like number of colors etc.).
Found something similar to what i want for the Color Range selection (opens the dialog with the presets you put in):
function colorrange(enabled, withDialog, fuzziness) {
    if (enabled != undefined && !enabled)
      return;
    var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
    var desc1 = new ActionDescriptor();
    desc1.putInteger(app.charIDToTypeID('Fzns'),fuzziness);
    var desc2 = new ActionDescriptor();
    desc2.putDouble(app.charIDToTypeID('Lmnc'), 31.22);
    desc2.putDouble(app.stringIDToTypeID("a"), 0.86);
    desc2.putDouble(app.stringIDToTypeID("b"), 0.31);
    desc1.putObject(app.charIDToTypeID('Mnm '), app.charIDToTypeID('LbCl'), desc2);
    var desc3 = new ActionDescriptor();
    desc3.putDouble(app.charIDToTypeID('Lmnc'), 95.34);
    desc3.putDouble(app.stringIDToTypeID("a"), 54.59);
    desc3.putDouble(app.stringIDToTypeID("b"), 49.85);
    desc1.putObject(app.charIDToTypeID('Mxm '), app.charIDToTypeID('LbCl'), desc3);
    desc1.putInteger(app.stringIDToTypeID("colorModel"), 0);
    var desc4 = new ActionDescriptor();
    var desc4 = executeAction(app.stringIDToTypeID('colorRange'), desc1, dialogMode);
How can i achieve the same for the indexed color conversion dialog? Apart from doing a lot of guessing regarding the stringIDs.
Is there some kind of "lookup table" for char and string IDs?
Thank you guys in advance! This forum has been a great help many times.

Ok never mind i got it, stupid me.
Recorded it with Script Listener and changed the "DialogMode" parameter of the executeAction function from "DialogModes.No" to "DialogModes.All".
var idCnvM = charIDToTypeID( "CnvM" );
            var desc249 = new ActionDescriptor();
            var idT = charIDToTypeID( "T " );
                var desc250 = new ActionDescriptor();
                var idPlt = charIDToTypeID( "Plt " );
                var idClrP = charIDToTypeID( "ClrP" );
                var idSele = charIDToTypeID( "Sele" );
                desc250.putEnumerated( idPlt, idClrP, idSele );
                var idClrs = charIDToTypeID( "Clrs" );
                desc250.putInteger( idClrs, 4 );
                var idFrcC = charIDToTypeID( "FrcC" );
                var idFrcC = charIDToTypeID( "FrcC" );
                var idNone = charIDToTypeID( "None" );
                desc250.putEnumerated( idFrcC, idFrcC, idNone );
                var idTrns = charIDToTypeID( "Trns" );
                desc250.putBoolean( idTrns, false );
                var idDthr = charIDToTypeID( "Dthr" );
                var idDthr = charIDToTypeID( "Dthr" );
                var idDfsn = charIDToTypeID( "Dfsn" );
                desc250.putEnumerated( idDthr, idDthr, idDfsn );
                var idDthA = charIDToTypeID( "DthA" );
                desc250.putInteger( idDthA, 75 );
            var idIndC = charIDToTypeID( "IndC" );
            desc249.putObject( idT, idIndC, desc250 );

Question on converting #FFFFFF to Color

Yea, I'm new at this but am having fun!. I have written an applet to replace and applet that I downloaded a few months ago. I need to set the colors of the foreground and background from <PARAM> tags in html. My question is how can I convert #FFFFFF that will be in the param tag to a Color object for setForeground() and setBackgroud()? I'm using a swing Applet.

Test this little program that convert any hexadecimal color to an RGB color :
import java.awt.*;
public class ColorConverter {
     public static void main(String[] args) {
          getColorFromHtml(0xffffff);
          getColorFromHtml(0xff0000);
          getColorFromHtml(0x00ff00);
          getColorFromHtml(0x0000ff);
     public static Color getColorFromHtml(int htmlColor) {
          int red = htmlColor>>16;
          int green = (htmlColor>>8)&0x00ff;
          int blue = htmlColor&0x0000ff;
          System.out.println("red :" +red+" green : "+green+" blue : "+blue);
          return(new Color(red, green, blue));
}------ unformatted version -----
import java.awt.*;
public class ColorConverter {
     public static void main(String[] args) {
          getColorFromHtml(0xffffff);
          getColorFromHtml(0xff0000);
          getColorFromHtml(0x00ff00);
          getColorFromHtml(0x0000ff);
     public static Color getColorFromHtml(int htmlColor) {
          int red = htmlColor>>16;
          int green = (htmlColor>>8)&0x00ff;
          int blue = htmlColor&0x0000ff;
          System.out.println("red :" red" green : "+green+" blue : "+blue);
          return(new Color(red, green, blue));
Before that you have to convert the string #FFFFFF to an int :
String s = "#FFFFFF";
s = s.substring(1);
int hexColor = Integer.parseInt(s, 16);
Color rgb = getColorFromHtml(hexColor);

Not able to convert string attribute to number and date please help me out

not able to convert string attribute to number and date attribute. While using string to date conversion it shows result as failure.As I am reading from a text file. please help me out

Hi,
You need to provide an example value that's failing and the date formats in the reference data you're using. It's more than likely you don't have the correct format in your ref data.

How can I convert a pages color document to a PDF Black and White doc.

How can I convert a pages color document to a PDF Black and White doc. Or, covert the color to B&W in a new doc?

> How can I convert a pages color document to a PDF Black and White doc. Or, covert the color to B&W in a new doc?
The general idea is that you colour correct photographs once, archive, and convert with or without colour changes. The archived photograph is unchanged - or we would be colour correcting the same photographs again and again and again.
If you have a photograph with a corrected exposure, you can open the photograph in the Apple ColorSync Utility, apply a colour space conversion to a grayscale appearance using the preinstalled ICC profile, save the photograph under another name, and place that in your pagination.
If you have a paginated document with corrected exposures, and any such non-scalable bitmap or scalable spline graphics as you have chosen to add, you can render the pagination as a whole to PDF through the same ICC profile, carrying out the same colour space conversion on any and all objects.
Caveat: If you intend the pagination for certain processes, in particular offset lithography, then you are probably expected not to render the type to grayscale, but rather to render it to single ink solid black. No software can determine what printing process you intend, you have to understand a bit about printing, and how to set up general colour space conversions in software. Ask your prepress provider, and if the answer is not prompt and proficient, pick another provider.

Convert String to Date and Format the Date Expression in SSRS

Hi,
I have a parameter used to select a month and year string that looks like:    jun-2013
I can convert it to a date, but what I want to do is, when a user selects a particular month-year  (let's say "jun-2013")
I populate one text box with the date the user selected , and (the challenge Im having is) I want to populate a text box next to the first text box with the month-year 2 months ahead.    So if the user selects
jun-2013   textbox A will show jun-2013
and textbox B will show aug-2013..
I have tried:
=Format(Format(CDate(Parameters!month.Value ),
"MM-YYYY" )+ 2 )   -- But this gives an error
This returns the month in number format   like "8"    for august...
=Format(Format(CDate(Parameters!month.Value ),
"MM" )+ 2 )
What is the proper syntax to give me the result    in this format = "aug-2013" ???
Thanks in advance.

You can convert a string that represents a date to a date object using the util.scand JavaScript method, and then format a date object to a string representation using the util.printd method. For more information, see:
http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.1254.html
http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.1251.html
In your case, the code would be something like:
var sDate = "2013-01-10";
// Convert string to date
var oDate = util.scand("yyyy-mm-dd", sDate);
// Convert date to new string
var sDate2 = util.printd("mm/dd/yyyy", oDate);
// Set a field value
getField("date2").value = sDate2;
The exact code you'd use depends on where you place the script and where you're getting the original date string, but this should get you started.

Convert String variable value to an Object referece type

Hi all,
I want to know that if there any possible way to convert String variable value to a Object reference type in java. I'll explain by example if this is not clear.
Let's think that there is a string variable name like,
String name="HelloWorld";
and there is a class name same to the variable value.
class HelloWorld
I am passing this string variable value to a method which is going to make a object of helloworld;
new convertobj().convert("HelloWorld");
class convertobj{
public void convert(String name){
// in hert it is going to create the object of HelloWorld;
// HelloWorld hello=new HelloWorld(); just like this.
now i want to do this from the name variable value.( name na=new name()) like wise.
please let me know if there any possible way to do that.
I am just passing the name of class by string variable then i wanted to make a instance of the class which come through the variable value.
thanx.

Either cast the object to a HelloWorld or use the reflection API (Google it) - with the reflection API you can discover what methods are available.
Note: if you are planning to pass in various string arguments and instantiate a class which you expect to have a certain method... you should define an interface and have all of your classes that you will call in this way implement the interface (that way you're sure the class has a method of that name). You can then just cast the object to the interface type and call the method.

Converting from indexed color to grayscale no longer works in CS4

I have a number of files to convert from indexed colors to grayscale. Did some but clicked "don't show me again" box on the Discard Colors warning. Now I can't make the conversion. Everything looks fine, but when I close file, then reopen, it's reverted to indexed colors - restarting Photoshop or the computer doesn't help.
I'd appreciate any help....Thanks, Grant

How to convert String (dd-MMM-yyyy) to oracle.jbo.domain.Date

Hi
Could you please tell how do I convert String of date in format dd-MM-yyyy to ADF date? Please show me some sample.
Thanks

http://javaalmanac.com/egs/java.text/FormatDateDef.html
Once you have a java.util.Date you can convert it to oracle.jbo.domain.Date. (see http://www.fifkredit.com/bc4jdoc/rt/oracle/jbo/domain/Date.html)

Convert from spot color to custom CMYK value in Applescript

I thought this would be very simple and it's not apparently. I am trying to convert a spot color into a custom CMYK value. Basically:
tell application "Adobe Illustrator"
          set theList to every path item of current document
          repeat with k from 1 to count of theList
                    if fill color of item k of theList = {name:"Dark Green"} then
                              set fill color of item k of theList to {cyan:0.0, magenta:100.0, yellow:0.0, black:0.0}
                    end if
          end repeat
end tell
But this script obviously doesn't work. From what I can tell, the fill color simply returns the tint of the item, not the name of it. I can't find anything that returns the name of a spot color so I can set the correct corresponding color. In the above example, I made the color obviously changed so I could visually see the result.
Any advice would be greatly appreciated! I'm a first time poster here.
Thanks!
