Hi everybody, I'm trying to exploit the image_lib tools to rescale twice an image got from an upload. My final goal is rescale the original image (of arbitrary size) once it's available after uploading, to a standard "big" size and a standard "small" (meaning thumbnail) size, getting two final images from one. For this, once got the image from the upload I run resize() a first time passing suitable values for the following parameters:
'source_image'=>'/path...',
'new_image'=>'/path...',
'create_thumb' => TRUE,
'width'=>$width_thumbnail,
'height'=>$height_thumbnail
This generates a new thumbnailed image, as desired. Then I clean up the parameters with:
$this->image_lib->clear()
and I re-run resize() passing:
'source_image'=>'/path...',
'width'=>$width_large_image,
'height'=>$height_large_image
missing the 'create_thumb' and 'new_image' parameters I thought I should have had a rescaling applied to the original image. However I saw it was not true, because $this->image_lib->clear() does not reset 'create_thumb'. In fact, forcing 'create_thumb' to FALSE in this second parameters set, I got the desired result.
First question: do you think this is a bug? I would say yes, I don't see any reason to clean all the variables but 'create_thumb'.
Second question: Don't you think it might be very useful to add another function, say $this->image_lib->reset(), which restores the default values of all variables? Because clear does not restore the defaults, but just sets all the values to empty strings.
Thanks
Davide
