This contribution would allow generation of thumbs once (not on the fly) according to sizes set by the user in the config. Do you think this is a necessary module?
I have to also replace function calls to tep_image_output with its wrapper com_image_output which figures which size image to get (depending on the SIZE parameter passed in).
// 5 different sized images are created
// they have a different prefix
// they are stored in the DIR_WS_THUMBS directory
//
// one very big wrapper for the tep_image function
function com_image_output($src, $alt = '', $type, $parameters = '') {
$width=''; $height= ''; $img_prefix='';
// and get prefix for this image's smaller size
// com_width and com_height are used in calling the tep_image_output function
list ($width, $height, $img_prefix) = com_image_query($src , $type );
if ($img_prefix == 'pib') { // this is the big, the default image size
return tep_image(DIR_WS_IMAGES . $src, $alt , $width , $height , $parameters );
}
$thumbfile = DIR_WS_THUMBS . $img_prefix . '_' . $src;
if (file_exists ($thumbfile)) {
return tep_image($thumbfile, $alt , $width , $height , $parameters );
} else { // need to make the thumb
// generate the thumb if necessary
copy(DIR_WS_IMAGES . $src, $thumbfile);
system("mogrify -resize '" . $width . "x" . $height . "' " . $thumbfile );
return tep_image($thumbfile , $alt , $width , $height , $parameters );
}
}
// called above
// called in some places to set table width depending on image size
//
function com_image_query($src , $type ) {
$width = '';
$height = '';
$img_prefix = '';
// Calcul des nouvelles dimensions
// add @ to suppress errors if category file does not exist yet
list($width, $height) = @getimagesize(DIR_WS_IMAGES . $src);
// return array($width, $height);
if ($type == PRODUCT_INFO_BIG ) {
$img_prefix = 'pib';
if ($width > $height ) {
$width = PRODUCT_INFO_WIDTH;
$height = PRODUCT_INFO_HEIGHT;
} else if ($height > $width ) {
$width = PRODUCT_INFO_WIDTH2;
$height = PRODUCT_INFO_HEIGHT2;
} else { // there are no categories
$width = PRODUCT_INFO_WIDTH; $height = PRODUCT_INFO_HEIGHT; }
}
if ($type == THUMB_SIZE || $type == PRODUCT_INFO_SMALL ) {
$img_prefix = 'ts'; if ($width > $height ) { $width = SMALL_IMAGE_WIDTH;
$height = SMALL_IMAGE_HEIGHT;
} else if ($height > $width ) {
$width = SMALL_IMAGE_WIDTH2;
$height = SMALL_IMAGE_HEIGHT2;
} else { // there are no categories
$width = SMALL_IMAGE_WIDTH;
$height = SMALL_IMAGE_HEIGHT;
}
}
return array($width, $height, $img_prefix);
}
// all the things in caps above are set in the configuration table
