php - CakePHP - How do you tell a controller's action to output a raw image header? -

i'm recoding existing project using cakephp framework. now, in existing code have php file (just called thumb.php) takes file , size , yields resized raw image browser. can utilized in instance image tag or other purposes. "thumbs.php" file uses header('content-type: image/jpeg'); output raw image.

anyway, here in action: http://www.dosspirit.net/php/thumb.php?file=268-transport-tycoon-deluxe-3.png&size=640

(you can alter size parameter 240 or 1240 , image resized you).

now, want replicate behaviour in cakephp.

so far, have setup:

class screenshotcontroller extends appcontroller { public function view() { (some code handle image scaling) } }

looking @ above code, urls screenshot this: http://www.domain/screenshot/view/268-transport-tycoon-deluxe-3.png/640

now, how can tell controller in cakephp output image header instead of going through view etc., hence mimicing functionality thumbs.php file ?

any response appreciated,

sincerely, - bakkelun

there's still php in cakephp. can same thing in action:

public function view() { header('…'); echo $imagedata; exit(); }

having said that, should utilize controller::header method output raw headers (for overrideable unit tests). better, should utilize media views output images cake way (which requires write file though).
