Description
===========

[](#description)

Using this library you can create images of different type of columns. If you use linear gradient on the column's wall, you can draw 3D-like shapes. It is mainly just for fun and learn algorithms used by the library.

See some examples: [examples.md](example/examples.md)

Installation
============

[](#installation)

```
php composer.phar require rimelek/columns3d:2.*

```

Requirements
============

[](#requirements)

- PHP &gt;= 7.0
- GD extension

Usage
=====

[](#usage)

Drawable elements
-----------------

[](#drawable-elements)

To start drawing you need to define a canvas

```
use Rimelek\Columns3D\Canvas;
use Rimelek\Columns3D\CanvasConfiguration;
use Rimelek\Columns3D\Color;

$cc = new CanvasConfiguration();
$cc->setHeight(300);
$cc->setWidth(300);
$cc->setType(Canvas::TYPE_JPEG); //Canvas::TYPE_PNG and Canvas::TYPE_GIF are also supported
$cc->setQuality(50); // Only in case of JPEG
$cc->setColor(new Color(255, 0, 0)); //RGB

$canvas = new Canvas($cc);

```

All methods of CanvasConfiguration are optional.

You can add elements to the canvas with addElement().

```
use Rimelek\Columns3D\PositionedElement;

// ...

$canvas->addElement(new Positionedelement($drawable, /*x*/ 200, /*y*/ 200));

```

$drawable object must implement Rimelek\\Columns3D\\Drawable\\DrawableInterface

Currently 2 classes are available:

**StripedPattern**

This is to add a striped background. For now, it does not support customization.

```
use Rimelek\Columns3D\Drawable\StripedPattern;

// ...

$background = new StripedPattern();
$canvas->addElement(new Positionedelement($background, 150, 150)); // background and the center of the canvas

```

**Column**

```
use Rimelek\Columns3D\Drawable\Column;
use Rimelek\Columns3D\Drawable\ColumnConfiguration;
use Rimelek\Columns3D\LinearGradient;

// ...

$colc = new ColumnConfiguration();
$colc->setRadius(100);
$colc->setVeticalAngle(0.2); //This is for 3D. Define it between 0 and 1. Greater values mean you look at the column from higher.
$colc->setHeigh(300);
$colc->setWallGradient(new LinearGradient(new Color(0, 0, 0), new Color(255, 255, 255)));
$colc->setColor(new Color(200 200, 200));

$column = new Column($colc);
$canvas->addElement(new PositionedElement($column, 200, 200));

```

All methods of ColumnConfiguration are optional.

Generator classes
-----------------

[](#generator-classes)

There are two generator classes too.

**PositionGenerator**

It is to generate positions of an ellipse to use it in a foreach loop.

```
$positionGenerator = new PositionGenerator($centerX, $centerY, $step /* Default is 1*/);
foreach ($positionGenerator->call(/* start degree*/ -150, /* end degree */ -30) as list($x, $y)) {
    $this->addElement(new PositionedElement($drawable, 200 + $x, 200 + $y));
}

```

**ColumnCircleGenerator**

Itt uses PositionGenerator to generate circle made of columns.

```
$columnCircleGenerator = new ColumnCircleGenerator($positionGenerator, $columnConfiguration);
foreach($columnCircleGenerator->call(/*degree*/$from, /*degree*/$to, $centerX, $centerY) as $e) {
    $canvas->addElement($e);
}

```
