public
__construct(Block $frame) : mixed
Parameters
- $frame : Block
Return values
mixed —calculate_auto_width()
Determine current frame width based on contents
public
calculate_auto_width() : float
Return values
float —dispose()
public
dispose() : mixed
Return values
mixed —get_dompdf()
public
get_dompdf() : Dompdf
Return values
Dompdf —get_min_max_width()
Required for table layout: Returns an array(0 => min, 1 => max, "min" => min, "max" => max) of the minimum and maximum widths of this frame.
public
get_min_max_width() : array<string|int, mixed>|null
This provides a basic implementation. Child classes should override this if necessary.
Return values
array<string|int, mixed>|null —process_clear()
public
process_clear(Frame $child) : mixed
Parameters
- $child : Frame
Return values
mixed —process_float()
public
process_float(Frame $child, float $cb_x, float $cb_w) : mixed
Parameters
- $child : Frame
- $cb_x : float
- $cb_w : float
Return values
mixed —reflow()
public
reflow([Block $block = null ]) : mixed|void
Parameters
- $block : Block = null
Return values
mixed|void —vertical_align()
Align inline children vertically.
public
vertical_align() : mixed
Aligns each child vertically after each line is reflowed
Return values
mixed —_calculate_content_height()
Determine the unrestricted height of content within the block not by adding each line's height, but by getting the last line's position.
protected
_calculate_content_height() : float
This because lines could have been pushed lower by a clearing element.
Return values
float —_calculate_restricted_height()
Determine the frame's restricted height
protected
_calculate_restricted_height() : array<string|int, mixed>
Return values
array<string|int, mixed> —_calculate_restricted_width()
