SetWidth works, resize doesn't?

new to ss and I find this very odd, hoping somebody can point me in the right direction. :-)

when I do this:

$myImage.SetWidth(150)

it outputs the image with the set width as expected - very cool.

however, when I do this:

$myImage.resize(150, 150)

I get "(150, 150)" on the page. am I doing something wrong?

Hi!

Wrong syntax, use instead: $myImage.SetSize(150,150) (http://doc.silverstripe.org/doku.php?id=image)

Hope it helps,
Juan

i havent had much luck with using 1 method to proportionately resize an image but you can check the orientation in the template, and depending on the orientation either call setHeight or setWidth.

hope it helps

With my experience working with images the best way is to make use of the php gd function by extend the image class.

1. create a php file called FittedImage.php

<?php
class FittedImage extends Image {

function generateMainImage($gd) {
$gd->setQuality(80);
return $gd->resizeRatio(370,240);
}

function generateThumbImage($gd) {
$gd->setQuality(80);
return $gd->resize(120,80);
}

}
?>

2.

static $has_one = array(
'GalleryImage' => 'FittedImage ',

);

3.

in you Template it can be

<img src="$GalleryImage.ThumbImage.URL" />

this will be for the small image which (may be ) on mouseover it displays the MainImage in another div

for the Main image

<img src="$GalleryImage.MainImage.URL" />

let me know if you need a URL for the site where this functionality is in place.

hope this makes sense

this is clearly explained here

Hi,

I use the same method of Pat jnr...

class Product extends Page {
static $db = array(
'DescrBreve' => 'Text',
'Evidence' => 'Boolean'
);

static $has_one = array(
'ProdottoImage1' => 'Product_Image',
)

etc...

class Product_Image extends Image {
function generateCroppedImage($gd) {
      $gd->setQuality(90);
      return $gd->croppedResize(300,130);
   }   

}

theni into template ( .ss file )

$ProdottoImage1.CroppedImage

Bye

I understand I can extend my classes, which is why I like silverstipe thus far. but should I view the prebuilt image function as unreliable? as I'm still in my newbie phase are there other types of things I should just write my own functionality for? I'm not sure I want to be getting into any scenarios where example code from tutorials isn't something I can count on...
