PixelCraft

PixelCraft

PixelCraft is a lightweight PHP library designed for easy image processing using the GD lib. With PixelCraft, you can perform basic image operations such as resizing, cropping, drawing of watermarks, and format conversion. The library is characterized by its user-friendly interface and minimal code footprint, allowing for quick and efficient image processing in PHP projects.

Requirements

• PHP >=5.3 (PHP 7.4, 8.2, 8.3 also compatible)
• GD Library
• Mbstring extension

Few usage examples

Minimal example

$pc=new PixelCraft();

$pc->createImage(640, 480);
$pc->fill('yellow');

$pc->addColor('sky', 34, 61, 216);
$pc->drawRectangle(0, 0, 640, 240, 'sky');

$pc->renderImage('png');

Image downscale and convertation from PNG to JPEG

$pc=new PixelCraft();

$pc->loadImage('someimage.png');
$pc->scale(0.5);

$pc->saveImage('resizedimage.jpg','jpeg');

Adding watermarks to images

$pixelCraft = new PixelCraft();

$pixelCraft->loadImage('yourimage.jpg');
$pixelCraft->loadWatermark('watermark.png');

$watermarkX=$pixelCraft->getImageWidth()-150;
$watermarkY=20;

$pixelCraft->drawWatermark(false,$watermarkX,$watermarkY);

$originalFileType=$pixelCraft->getImageType();
$pixelCraft->renderImage($originalFileType);

Instagram-like filters

$pixelCraft = new PixelCraft();

$pixelCraft->loadImage('yourimage.jpg');

$filtersSet = array();
$filtersSet[] = array(IMG_FILTER_BRIGHTNESS => -15);
$filtersSet[] = array(IMG_FILTER_GRAYSCALE => -5);
$filtersSet[] = array(IMG_FILTER_COLORIZE => array(80, 0, 60));
$filtersSet[] = array(IMG_FILTER_GAUSSIAN_BLUR => '');

$pixelCraft->imageFilters($filtersSet);

$pixelCraft->renderImage('jpeg');

Adding text to image

$pixelCraft = new PixelCraft();

$pixelCraft->loadImage('yourimage.jpg');

$labelPosition = ($pixelCraft->getImageHeight()) - 10;
$pixelCraft->drawTextAutoSize($labelPosition, 10, 'Text at image bootom', 'white', 'black');

$pixelCraft->renderImage('jpeg');

Drawing pixel-art

$pixelCraft = new PixelCraft();

$pixelMap = '
