Functions

crop_to_constraint [line 59]

array crop_to_constraint(
integer $src_width, integer $src_height, integer $max_width, integer $max_height 
)

Crop dimensions to fit into a constrained size, while preserving aspect ratio.

Parameters:

integer	$src_width:	source width
integer	$src_height:	source height
integer	$max_width:	constrained width
integer	$max_height:	constrained height

API Tags:

Return:

( x, y, width, height )

fit_into_constraint [line 121]

void fit_into_constraint(
integer $src_width, integer $src_height, integer $max_width, integer $max_height 
)

Scale dimensions to fit into a constrained size, while preserving aspect ratio.

The scaling only happens if the source is larger than the constraint.

Parameters:

integer	$src_width:	source width
integer	$src_height:	source height
integer	$max_width:	constrained width
integer	$max_height:	constrained height
