[Image] New Button Tag and Text Tag with HTML rendering capability
I thought of writing a tag to create Buttons because a lot of people
require this functionality (to create text buttons in different
languages) and I keep on explaining how to do it with a combination of
the basic image tags. I did not add this tag to the Image Taglib because
I thought it was best if the lib just had a set of basic operations
leaving the more complex transformations that are just a combination of
these basic ones to the user (or maybe maintain it outside separately
for those who need it). However since a lot of people had been asking
for it, I am thinking of adding a button tag too. Later we could remove
it if we feel that it does not belong here.
The button tag is basically the "text" (text overlay) tag and the crop
tag combined. But the boundaries may have to be calculated based on the
width of the text printed. I also thought that it was time to upgrade
the Text tag to support multilined text. The text overlay is the first
operation for the button tag. Ideally it required some more formatting
options than just specifying a font and color. Thats why I thought it
was best to add HTML rendering capability to the Text and Button Tags.
See an example here
(http://www.mullassery.com/downloads/images/woods-poem.jpg)
The HTML (poem) is overlaid on the image. This was rendered on the image
using the classes in the JDK.
The text tag with HTML rendering capability can also take a URL and
render a "screenshot" of the page as an image.
I wanted to know your opinion about this feature and the best HTML
rendering package to use for it.
Also is the button tag required in the taglib?
Thanks.

Hi, Abey,
I have been under the gun here and will get back to you on this. For the
moment, I thought it might be helpful to send along this code that I use to
put i18n text into buttons.
package com.crackwillow.resource.image.button;
import java.io.*;
import java.util.*;
import com.crackwillow.log.StdOut;
public class UnicodeConverter {
public static String convert(String unicode) {
try {
byte [] utf8Bytes = unicode.getBytes("UTF8");
unicode = new String(utf8Bytes,"UTF8");
} catch (UnsupportedEncodingException uee) {
log("log.error",uee.getMessage());
}
return unicode;
}
public static void log(String logFileName,String message) {
StdOut.log(logFileName,message);
}
} ///;-) Michael McGrady
Later,
Michael

Re: [Image] New Button Tag and Text Tag with HTML rendering capability
Posted by Abey Mullassery <ab...@mullassery.com>.
"HTML rendering capability" means that the Text tag can be supplied with
HTML text/ source and the tag renders it (somewhat like a browser). This
allows one to add a lot of formatting to the text input.
For example the tag for the image
(http://www.mullassery.com/downloads/images/woods-poem.jpg)
can be similar to..
<img:image src="/images/woods.jpg"
name="woods-poem.jpg">
<img:text font="Arial"
bold="true"
size="14"
color="0x0000ff"
>
<h3><font color="#8a4f60">Stopping By Woods On A Snowy Evening</font></h3>
<font color="#8a4f60">
Whose woods these are I think I know.<br>
His house is in the village though;<br>
He will not see me stopping here<br>
To watch his woods fill up with snow.<br>
<br>
....
<br>
The woods are lovely, dark and deep.<br>
But I have promises to keep,<br>
And miles to go before I sleep,<br>
And miles to go before I sleep.<br>

Hi, Abey,
I am thinking about your questions. I have some thoughts at the present
which will be incomplete, depending upon what you have to say. I am not
sure what you mean by "HTML enabled Text tag feature". I have some general
thoughts about the image taglib, which I will share below in some limited
detail.
I have included the text bounds calculations in my button making
code. Since my last email, I have added borders on copies of the buttons
so you can see how this worked out at http://131.191.40.91:14567/testText.jsp.
ON YOUR QUESTIONS
First "Issue": Administrative HTML
I like having both an administrative HTML to make buttons and a
presentation HTML to do buttons on the page with caching. I think that
making an administrative HTML with an xml or properties login is definitely
something that the image taglib needs. The interface should be such that
it could be easily moved to MySQL, Oracle, HSQLDB, etc., and we might even
provide alternative uses ot the interfaces for those options. The
administrative HTML would or could do extra things, which I would build for
myself if it did not have them, such as provide the user with a list of the
fonts on the local machine, a color chart to choose colors from, etc. The
administrative HTML would help the page designer choose the colors.
Second "Issue": Presentation HTML
I am still not well enough acquainted with the tag itself to be of real
help here. My main concern would be with quality and efficient cache
control. I will await your note about what HTML redendered means in this
context before adding more thoughts on this.

You cannot "steal" open source code. It is for everybody to "take",
modify and use as they like it. Thats the beauty of it :-)
You can just subclass Button Tag from Text tag and add a crop based on
the bounds calculations. I will check in the code in a couple of days..
hope to get some opinions/feedback by then.
The combination of the basic tags will not get you well "cropped" button
unless you do your text bounds calculation separately, which is
difficult (you need the graphics object to get the correct
fontRenderContext) and should be inside the tag. That is why I am
planning to add the Button tag to the lib.
The good thing about HTML rendered Text Tag is that it supports
multiline and much better formatting.
Your did not mention your views on my questions!
1. Your opinion about the HTML enabled Text tag feature and the best
HTML rendering package to use for it.
2. Is the Button tag required in the taglib?
Thanks,

Re: [Image] New Button Tag and Text Tag with HTML rendering
capability
Posted by mike <mi...@michaelmcgrady.com>.
Hello, Abey,
I was getting a page not available error, but have now seen your work. Very
nice. I think there is too much antialiazing, however. I have
experimented with trying to get a better "look" to the printing, and think
I have succeeded. Assuming my laptop is running, the URL
http://131.191.40.91:14567/testText.jsp has a demonstration. The images
named "mable", "submit" and "yahoo" are made with the code changes, and the
"myButton2", "myButton3", "myButton4" and "myButton5" are from your
classes. I stole most of the code and am still "fitzing" about with it. I
first read/load any GIF and resize it to the text I am going to use
(ButtonFactory.resize()) and make it transparent, writing it with whatever
name I want. Then, I read the new GIF and add the new text. I think some
of the (int) casts may be affecting the quality of the letters in your
code. I admit, however, that my knowledge is really, really, scanty and I
may be full of blarney on everything.
If you would like to see the code, how do I get it to the people on the list?
Michael
