[PEPr] Comment on Images::Image_CAPTCHA

Martin Jansen (http://pear.php.net/user/mj) has commented on the proposal for Images::Image_CAPTCHA. Comment: A few points: - You are using var_dump() at some point in the code, which is probably not desired. - Can you replace NULL with null? - The comment /** * Image_CAPTCHA - see above * * see above * * @package Image_Text */ is misleading, because in the API documentation there may be no text "above", because the blocks are split up into multiple files. - Inside a for-loop, you do not make use of the 4-spaces indentation. Apart from that the code seems to be fine. Proposal information: http://pear.php.net/pepr/pepr-proposal-show.php?id=80 -- Sent by PEPr, the automatic proposal system at http://pear.php.net
