delputnam / icaptcha Goto Github PK

What steps will reproduce the problem?
1. in the properties you set bezier as true
2.
3.

What is the expected output? What do you see instead?

Bezier curve should get display

What version of the product are you using? On what operating system?


Please provide any additional information below.

What steps will reproduce the problem?

No X11 on server and/or no X11 libs on server, this captcha won't work
within JSP or servlet code.   

Please provide any additional information below.

Quick fix:
 Font font = new  Font(fontName, Font.BOLD,  fontSize);
// GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
// GraphicsDevice gs = ge.getDefaultScreenDevice();
// GraphicsConfiguration gc = gs.getDefaultConfiguration();
// Create an image that supports arbitrary levels of transparency
BufferedImage buffer = new BufferedImage(1, 1, IMAGE_TYPE_BUFFERED);             
Why do you use the GraphicsEnvironment and other X11 dependent class?

If following conditions will are met
1.  Using BoxedbackgroundProducer
2.  Setting "intersect" property to "false"
3.  Setting "minboxes" property to ">1"


Sometimes this will produce infinite or long running loops, reason for this
is that the width/height is randomized and sometimes width is given all
area so the next randomly generated box have no place to occyp

What steps will reproduce the problem?
1. in the sample code replace the FactorySimpleMathImpl with 
FactoryRandomImpl in the captcha.jsp and index.jsp
2. run the project on server and look into the console for the value
returned by the solver
3. Please note that i have not changed the instProps values in captcha.jsp
as i was not aware about the property names for FactoryRandomImpl.

What is the expected output? What do you see instead?
Must show VERIFIED instead showing Not Verified even if we give the right
values.

What version of the product are you using? On what operating system?
Project given as example in Windows.

Please provide any additional information below.
I am using JRE 1.5.0,TOMCAT 5.5

Due to request I will be adding RPN for parsing +-*/() so we can  create 
mathematical expression to use as captchas.

What steps will reproduce the problem?
1. Run the example in a tomacat instance that uses the jre1.4
2.
3.

What is the expected output? What do you see instead?
Need to get the result but we are getting an error 
Generated servlet error:

What version of the product are you using? On what operating system?
JDK1.4 and webserver is tomcat 5.0.28

Please provide any additional information below.

What steps will reproduce the problem?
1. Check out the read-only source from SVN
2. Run "ant" in the project's root directory

The compiler complains about the "-source 1.4" switch.

build:
    [javac] Compiling 23 source files to
/home/andy/projects/icaptcha/icaptcha-read-only/classes
    [javac]
/home/andy/projects/icaptcha/icaptcha-read-only/src/org/smx/captcha/IBackgroundP
roducer.java:5:
generics are not supported in -source 1.4
    [javac] (use -source 5 or higher to enable generics)

You need to set the javac task to use at JDK5:
<javac source="5" srcdir="${src}" destdir="${classes}" debug="true"
optimize="true">

What steps will reproduce the problem?
1. Installed icaptcha.war in Tomcat
2. Open http://localhost:8080/icaptcha/index.jsp
3. Click on Reload

What is the expected output? What do you see instead?
The Image should get refreshed But instead I am not able to see any image
in the location. I tries to debug it and found that in captcha.jsp while
rendering the image using Producer.render(os, solver, props), the following
error is getting thrown:
