I have an image with the dimension of (W-3000 X H-4000). When i upload it and resize, it always show like landscape mode, mean new dimension is w-1067 X h-800. I want to create this picture either 800X600 for landscape or 600X800 for portrait. Here is my code:
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'jpg|jpeg|gif|png';
$config['max_size'] = '5000';
$this->load->library('upload', $config);
//check if a file is being uploaded
if(strlen($_FILES["testimg"]["name"])>0){
if ( !$this->upload->do_upload("testimg"))//Check if upload is unsuccessful
{
$error = array('error' => $this->upload->display_errors());
print_r($errors);
}
else
{
$config['image_library'] = 'gd2';
$config['source_image'] = $this->upload->upload_path.$this->upload->file_name;
$config['width'] = '1';
$config['height'] = '800';
$config['maintain_ratio'] = TRUE;
$config['master_dim'] = 'height';
$this->load->library('image_lib',$config);
if (!$this->image_lib->resize()){
echo "error";
}else{
echo "success";
}
}
}
In my code height is always 800px in size. It is ok for 3000X4000 dimension image. But what about when i use 4000X3000 dimension image? Can any one help me about this issue? Thanks
Thanks @Rpojka for your answer. But I fixed it with exif_read_data() . Here is my code:
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'jpg|jpeg|gif|png';
$config['max_size'] = '6048';
$this->load->library('upload', $config);
//check if a file is being uploaded
if(strlen($_FILES["testimg"]["name"])>0){
if ( !$this->upload->do_upload("testimg"))//Check if upload is unsuccessful
{
$error = array('error' => $this->upload->display_errors());
print_r($errors);
}
else
{
$config['image_library'] = 'gd2';
$config['source_image'] = $this->upload->upload_path.$this->upload->file_name;
$filename = $_FILES['testimg']['tmp_name'];
$imgdata=exif_read_data($this->upload->upload_path.$this->upload->file_name, 'IFD0');
list($width, $height) = getimagesize($filename);
if ($width >= $height){
$config['width'] = 800;
}
else{
$config['height'] = 800;
}
$config['master_dim'] = 'auto';
$this->load->library('image_lib',$config);
if (!$this->image_lib->resize()){
echo "error";
}else{
$this->image_lib->clear();
$config=array();
$config['image_library'] = 'gd2';
$config['source_image'] = $this->upload->upload_path.$this->upload->file_name;
switch($imgdata['Orientation']) {
case 3:
$config['rotation_angle']='180';
break;
case 6:
$config['rotation_angle']='270';
break;
case 8:
$config['rotation_angle']='90';
break;
}
$this->image_lib->initialize($config);
$this->image_lib->rotate();
}
}
}
Here is the exif orientation chart
1 2 3 4 5 6 7 8

$filename = $_FILES['testing']['tmp_name'];
list($width, $height) = getimagesize($filename);
if ($width >= $height)
{
$config['width'] = 800;
$config['master_dim'] = 'width';
}
else
{
$config['height'] = 800;
$config['master_dim'] = 'height';
}
Even shorter, you can use 'auto' parameter for master_dim that will determine which value is greater - width or height.
$filename = $_FILES['testing']['tmp_name'];
list($width, $height) = getimagesize($filename);
if ($width >= $height)
{
$config['width'] = 800;
}
else
{
$config['height'] = 800;
}
$config['master_dim'] = 'auto';
