NAME

PDF::Make::Render - Native path rendering for PDF content

SYNOPSIS

use PDF::Make::Render;

# Create a render context
my $ctx = PDF::Make::Render->new(800, 600);

# Set up graphics state
$ctx->save;
$ctx->set_fill_color(1, 0, 0);  # Red
$ctx->set_stroke_color(0, 0, 0);
$ctx->set_line_width(2);

# Build a path
$ctx->move_to(100, 100);
$ctx->line_to(200, 100);
$ctx->line_to(200, 200);
$ctx->close_path;

# Render
$ctx->fill;

$ctx->restore;

# Get pixel data
my $pixels = $ctx->get_pixels;

DESCRIPTION

PDF::Make::Render provides a native path rendering engine for PDF content. It implements PDF's imaging model including paths, fills, strokes, clipping, and transformations.

METHODS

new($width, $height)

Create a new render context with the specified dimensions.

width / height

Get the dimensions of the render context.

clear($r, $g, $b, $a)

Clear the context to the specified color.

save / restore

Save or restore graphics state.

Path Building

move_to($x, $y)

Begin a new subpath.

line_to($x, $y)

Add a line segment.

curve_to($x1, $y1, $x2, $y2, $x3, $y3)

Add a cubic Bezier curve.

close_path

Close the current subpath.

rectangle($x, $y, $w, $h)

Add a rectangle to the path.

Path Painting

fill

Fill the current path using non-zero winding rule.

stroke

Stroke the current path.

fill_stroke

Fill and stroke the current path.

clip

Clip to the current path.

Color

set_fill_color($r, $g, $b, $a)

Set the fill color.

set_stroke_color($r, $g, $b, $a)

Set the stroke color.

Line Properties

set_line_width($width)

Set the line width.

set_line_cap($cap)

Set line cap style (0=butt, 1=round, 2=square).

set_line_join($join)

Set line join style (0=miter, 1=round, 2=bevel).

set_miter_limit($limit)

Set the miter limit.

Transformations

set_matrix($a, $b, $c, $d, $e, $f)

Set the current transformation matrix.

concat_matrix($a, $b, $c, $d, $e, $f)

Concatenate a matrix with the current CTM.

Output

get_pixels

Get the raw pixel data as a scalar (RGBA format).

get_pixel($x, $y)

Get a single pixel as ($r, $g, $b, $a).
