Grand Optimizer is a real-time on the fly image manipulation and optimization service that automatically optimizes your images for faster image delivery, bandwidth savings and enables smart dynamic image manipulation using a simple query API.
The system is currently in private Beta testing. If you're interested in participating, please let us know.
This article explains the image optimizer engine query API.
- Aspect Ratio Crop
- Crop Gravity
- Automatic Optimization
Parameter: width Units: Pixels Default: auto
Resize the output image to the given width maintaining the current aspect ratio.
Parameter: height Units: Pixels Default: auto
Resize the output image to the given height maintaining the current aspect ratio.
Aspect Ratio Crop
Parameter: aspect_ratio Default: auto
Automatically crop the output image into the given aspect ratio with a central gravity.
Parameter: quality Units: Percent Range: 0-100 Default: 85
Optimize the output image to the given compression level, 0 being the lowest and 100 being the highest. Lowering the quality will reduce file size, but might start visibly reducing image quality with values below 70.
Parameter: sharpen Units: Boolean Default: false
Sharpen the output image.
Parameter: blur Units: Number Range: 0-100 Default: 0
Blur the output image.
Parameter: crop Units: Pixels Format 1: width,height Format 2: width,height,x,y
Crop the output image to the given width and height. Two formats are accepted. Format 1 one only includes the width and height of the crop. Format 2 also includes the X and Y position where the crop should start. Image resizing with the width and height parameters is processed before the crop and the resized measurements apply.
If only width and height are given, the Crop Gravity parameter will be used.
Parameter: crop_gravity Default: center
Set the gravity of the crop operation. This is used with the Format 1 cropping only and snaps the crop to the selected position.
Parameter: flip Units: Boolean Default: false
Flip the output image vertically.
Parameter: flop Units: Boolean Default: false
Flip the output image horizontally.
Parameter: brightness Units: Number Range: -100-100 Default: 0
Adjusts the brightness of the output image.
Parameter: saturation Units: Number Range: -100-100 Default: 0
Adjusts the saturation of the output image. Use -100 for grayscale.
Parameter: hue Units: Number Range: 0-100 Default: 0
Adjusts the hue of the output image by rotating the color wheel. The default value of 0 is the base color and increasing the value modulates to the next color for each 33 change.
Parameter: gamma Units: Number Range: -100-100 Default: 0
Adjusts the gamma of the output image.
Parameter: contrast Units: Number Range: 0-100 Default: 0
Adjusts the contrast of the output image.
Parameter: auto_optimize Units: String Values: low,medium,high Default: none
Automatically enhance the output image with multiple levels of optimizations. With high, sharpening is also applied automatically.
