Fork me on GitHub: https://github.com/elgervb/imagemanipulation
Library to manipulate images using PHP's GD library. Most of the functionality is available through the ImageBuilder facade.
This way chaining of image filters and thumbnailing is possible, like:
ImageBuilder::create( new \SplFileInfo('image.jpg') )
->contrast( 20 ) // increase contrast
->colorize( '#DB3636' ) // apply a bit of red the the image
->flip( ImageFilterFlip::FLIP_VERTICALLY ) // flip image vertically
->save( new \SplFileInfo( 'image.new.png' ) ) // save the jpg image as png with filters applied
->render( 80 ); // render to browser with quality 80 "require" : {
"elgervb/imagemanipulation": "^1.0"
}
PHP version >= 5.3 with GD library
Lots of image filters. All of them listed below:
- brightness
- colorize
- comic
- contrast
- convolution 3x3 filters
- darken
- dodge
- duotone
- edge detect
- emboss
- find edges
- flip (horizonal, vertical, both)
- gamma correction
- gaussian blur
- grayscale
- hue rotate
- mean remove
- motion blur
- negative
- noise
- old cardboard
- opacity
- pixelate
- random blocks with custom size and color
- replace color
- reverse
- rounded corners
- scatter
- selective blur
- semi grayscale
- sepia
- sepia fast
- sharpen
- smooth
- sobel edge detect
- sobel edge enhance (based on convolution matrix)
- true color
- vignette
Use an image as overlay on another image. Can be configured with overlay opacity, start and end position and fill options.
Use the current image to make a reflection below the original image
Repeat images on a canvas, until it fits. This way we can create Warhol like images.
Rotate images in degrees. When rotating an image not equal to 90, 180, 270 or 360 degrees, then optionally you can specify a background color for those oncovered edges.
Create thumbnails on the fly. There are several strategies to use:
- Centered strategy: create a thumb from the center of an image. Ideal for creating square thumbs from not so square images
- Max strategy: resize the image to a max width or height keeping proportions. For example: when resizing an image (300x750) on max 500 pixels, the resulting image will be 200x500 pixels
- Percentage strategy: reduce the size of an image with a certain percentage.
Add a watermark to your image. Possible positions are: top, bottom, left, right, center, top right, top left, bottom right, bottom left.
