admin This is really nightmare to sort out why loop operation get success only for first time. Say, with or without loop i want to resize two images in a single script. i write the resize code but when i execute i found only first image is resized but not second one. WHY??????
after search and search, R&D, test and test finally able to find out the reason. a single line of extra code resolve my issue. and now i am able to resize 100 images inside a loop or write code multiple times to manipulate multiple images. This is the extra line of code:
$this->image_lib->initialize($config);
and here i am croping 100 of images using CI
foreach (glob(“./newspaper-jobs/prothom-alo/2009-05-22/*.jpg”) as $filename)
{
list($width, $height, $type, $attr) = getimagesize($filename);
//here are some logic. set it as you need or discard this portion but adjust variables by yourself.
$crop_x_axis = 0;
if($width<$height)
{
$crop_height_width = $width;
}
else // $width>$height
{
$crop_height_width = $height;
$crop_x_axis = ($width-$height)/2;
}
unset($config);
//Crop an image(Height = Width) Depend on current Height and Width of image
$config['image_library'] = ‘gd2′;
echo $config['source_image'] = ‘./source/image/location/’.basename($filename);
$config['new_image'] = ‘./destination/loc/’.basename($filename);
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = FALSE;
echo $config['width'] = $crop_height_width;
echo $config['height'] = $crop_height_width;
echo $config['x_axis'] = $crop_x_axis;
$config['y_axis'] = 0;
$this->load->library(‘image_lib’, $config);
$this->image_lib->initialize($config);
if ( ! $this->image_lib->crop())
{
echo $this->image_lib->display_errors();
}
$this->image_lib->clear();
}
Enjoy image resizing/croping/or whatever it is !!!
