if i set_background_colour to #TRANSPARENT the property $this->background_colour returns nothing, for this reason i do ..

if($this->background_colour != ""){

works… but it’s a hack…

Other question:

Can i set something like master_dim param to fix width and always only resize the height?

Thank you for this library, it’s great.

Sorry my english…

Yes but $this->image_moo->errors will be true as the _html2rgb routine will fail. Remember that the functions return a reference to self not a result to a function. As for master, just resize with a really large width (9999) that way height will always be used.

Thank you, works fine!

Hi,

First of all, thank you for this awesome library.  A little correction to the documentation:

On your example after dealing with the image library, to show any error you use:

if ($this->image_moo->error) print $this->image_moo->display_errors();

It should be:

if ($this->image_moo->errors) print $this->image_moo->display_errors();

Note the ‘s’ on error

BTW, I need a little help:

I’m using jcrop to send the coordinates to crop the image. It works fine. The problem is that after cropping it I need to resize it to 150, 150.

He is my crop_thumbnail function:

function crop_thumbnail($id_artists) {
        $this->load->library('image_moo');
        $this->image_moo
                        ->load($this->input->post('filetocrop'))
                        ->crop($this->input->post('x'), $this->input->post('y'), $this->input->post('x2'), $this->input->post('y2'))
                        ->save_pa("", "_thumb", TRUE);

        if ($this->image_moo->errors)
            print $this->image_moo->display_errors();
    }

If I use:

$this->image_moo
                        ->load($this->input->post('filetocrop'))
                        ->crop($this->input->post('x'), $this->input->post('y'), $this->input->post('x2'), $this->input->post('y2'))
                        ->resize(150,150),
                        ->save_pa("", "_thumb", TRUE)

It resizes the orignal image, not the crop.

My idea was to load another instance of image moo and then resize the new thumb file, but since I’m using save_pa and appending ‘_thumb’ to the file, how to retrieve the new thumb file name before resizing it? Is there any easy way to get the new thumb file name? Or I would need a regex to take the extension out then add_thumb to the name and concatenate with the extension again?

Thanks

Thanks for the errors catch.

public function load_temp()
 //----------------------------------------------------------------------------------------------------------
 // Take the temp image and make it the main image
 //----------------------------------------------------------------------------------------------------------
 {
  // validate we loaded a main image
  if (!$this->_check_image()) return $this;

  if (!is_resource($this->temp_image))
  {
   $this->set_error("No temp image created!");
   return FALSE;
  }

  $this->main_image = $this->temp_image;
  $this->width = imageSX($this->main_image);
  $this->height = imageSY($this->main_image);
  $this->clear_temp();

  // return the object
  return $this;
 }

try adding the above (untested)
then

$this->image_moo
                        ->load($this->input->post('filetocrop'))
                        ->crop($this->input->post('x'), $this->input->post('y'), $this->input->post('x2'), $this->input->post('y2'))
                        ->load_temp()
                        ->resize(150,150),
                        ->save_pa("", "_thumb", TRUE)

It should in theory replace the main loaded image, with your cropped image, then resize as normal.

Thank for your reply. But, unfortunately it didn’t work.

Getting No main image loaded! error

Thanks,

$this->image_moo
                        ->load($this->input->post('filetocrop'))
                        ->save_pa("", "_thumb", TRUE);

Does that work at all? I would of thought you would of needed to process the upload, save it as a temp file and load the temp file (e.g. look at the upload helper)

$this->image_moo
                        ->load($this->input->post('filetocrop'))
                        ->save_pa("", "_thumb", TRUE);

This works fine. I had thought on the same suggestion you provided. I was just wondering if there was anything like that built in into image_moo library. No big deal though.

Thank you very much

I’d like to have an image have a set width (to fill a column width) but a max height - if height exceeds, do a resize_crop using set width and max height. Can this library easily do this?

Cheers

Resize_crop should work from memory (Sorry not got the code with me)

Is there any way to convert all images to jpg?

Just save with a new .jpg filename and it should convert for you.

The CI library for image manipulation is great, but I found it awkward to use when doing multiple processes.

You aren’t kidding about CI’s image_lib library being awkward to use, including and ESPECIALLY for multiple processes. I just spent the last few days trying to do exactly what your resize_crop function does in the image_moo library. I still was not able to figure it out…... and then I found your library and it worked instantly…. thank you sooooo much for writing that awesome image library and providing it to the community. 😊

I don’t think resize_crop does it - I believe it is expanding the image to fit dimensions while center cropping it. If so, is there anyway you could implement this?
