Bug description: using imagecreatefromstring, howto get imagetype?
Description:
------------
I use imagecreatefromstring to load a binary stream, which is probably a
jpeg image (thumbnail).
With imagesx and imagesy I can retrieve the width and height of the
resource, but I cannot retrieve the imagetype or mimetype of the
resource.
As described in the imagecreatefromstring function documentation, the
imagetype will be automatically detected if the build of PHP can support
it.
Maybe an imagestype function can retrieve the imagetype from an image
resource?
Reproduce code:
---------------
<?php
$data = 'iVBORw0KGgoAAAANSUhEUgAAABwAAAASCAMAAAB/2U7WAAAABl'
. 'BMVEUAAAD///+l2Z/dAAAASUlEQVR4XqWQUQoAIAxC2/0vXZDr'
. 'EX4IJTRkb7lobNUStXsB0jIXIAMSsQnWlsV+wULF4Avk9fLq2r'
. '8a5HSE35Q3eO2XP1A1wQkZSgETvDtKdQAAAABJRU5ErkJggg==';
$data = base64_decode($data);
$im = imagecreatefromstring($data);
echo "width: ".imagesx ($im)."\n";
echo "height: ".imagesy ($im)."\n";
echo "type: ".imagestype ($im)."\n";
?>
Expected result:
----------------
width: 28
height: 28
type: 3
Actual result:
--------------
width: 28
height: 18
