Re: [Zope] Captcha
well, i mean, given the python implementations that are available, that code on this site can be adapted and used to generate a captcha image object. 2005/9/14, Brian Sullivan <[EMAIL PROTECTED]>: > > > On 9/14/05, akonsu <[EMAIL PROTECTED]> wrote: > > as i said earlier, > http://cvs.bluedynamics.org/viewcvs/BlueTexima/ > > seems to have code that dynamically creates an image object. would > > this help? > > > Possibly but that is only part of the puzzle - usually the image has > distorted text on a mottled background to further complicate and confuse > automatic readers and force a human read. > > > ___ > Zope maillist - Zope@zope.org > http://mail.zope.org/mailman/listinfo/zope > ** No cross posts or HTML encoding! ** > (Related lists - > http://mail.zope.org/mailman/listinfo/zope-announce > http://mail.zope.org/mailman/listinfo/zope-dev ) > > > ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Possibly but that is only part of the puzzle - usually the image has distorted text on a mottled background to further complicate and confuse automatic readers and force a human read. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

No it cant - you cannot use it to obfuscate text like your captcha product seems to do. But some people are using text-to-image products to render buttons and this is where you can use CSS instead. Btw. Text-to-image obfuscation makes it harder for machines to automatically fill out forms but not impossible. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
