The manualCrop method crops a specific area of the image by specifying the $startX and $startY positions and the crop's $width and $height in pixels. $image -> focalCrop ( int $width, int $height, int $focalX, int $focalY, float $zoom = 1 ) #Manual crop
Each step represents a 100% zoom, so passing 2 will be the same as viewing the image at 200%. Zoom is controlled by a floating point ranging from 1 to 100. You can also zoom into your focal point, if needed. The center of the crop is controlled by the $focalX and $focalY values in percent ( 0 - 100). The focalCrop method can be used to crop around an exact position. #Example usage Image :: load ( 'example.jpg' ) -> crop ( Manipulations :: CROP_TOP_RIGHT, 250, 250 ) -> save () The following $cropMethods are available through constants of the Manipulations class:ĬROP_TOP_LEFT, CROP_TOP, CROP_TOP_RIGHT, CROP_LEFT, CROP_CENTER, CROP_RIGHT, CROP_BOTTOM_LEFT, CROP_BOTTOM, CROP_BOTTOM_RIGHT. $image -> crop ( string $cropMethod, int $width, int $height) Use the $cropMethod to specify which part will be cropped out. #Example usage Image :: load ( 'example.jpg' ) -> fit ( Manipulations :: FIT_STRETCH, 450, 150 ) -> save () īy calling the crop method part of the image will be cropped to the given $width and $height dimensions (pixels). The resulting image will match the width and height constraints without distorting the image. Resizes the image to fill the width and height boundaries and crops any excess image data. The resulting image will fill the dimensions, and will not maintain the aspect ratio of the input image. Stretches the image to fit the constraining dimensions exactly. # Example of how to set background colour to fill remaining pixels $image -> fit ( Manipulations :: FIT_FILL, 497, 290 ) -> background ( '007698' ) The resulting image will match the constraining dimensions. Resizes the image to fit within the width and height boundaries without cropping or distorting the image, and the remaining space is filled with the background color. Resizes the image to fit within the width and height boundaries without cropping, distorting or altering the aspect ratio, and will also not increase the size of the image if it is smaller than the output size. Resizes the image to fit within the width and height boundaries without cropping, distorting or altering the aspect ratio. The following $fitMethods are available through constants of the Manipulations class: # Manipulations::FIT_CONTAIN (Default) $image -> fit ( string $fitMethod, int $width, int $height) The fit method fits the image within the given $width and $height dimensions (pixels) using a certain $fitMethod.
$image -> width ( int $width) $image -> height ( int $height) #Example usage Image :: load ( 'example.jpg' ) -> width ( 250 ) -> height ( 250 ) -> save () The resized image will be contained within the given $width and $height dimensions respecting the original aspect ratio. The width and height of the Image can be modified by calling the width and height functions and passing in the desired dimensions in pixels.
