Image effects and enhancements

Cloudinary's visual effects and enhancements are a great way to easily change the way your images look within your site or application. For example, you can change the shape of your images, blur and pixelate them, apply quality improvements, make color adjustments, change the look and feel with fun effects, apply filters, and much more. You can also apply multiple effects to an image by applying each effect as a separate chained transformation.

Some transformations use fairly simple syntax, whereas others require more explanation - examples of these types of transformations are shown in the advanced syntax examples.

On this page:

Advanced syntax examples

In general, most of the visual effects and enhancements can take an additional option to tailor the effect to your liking. For some, however, you may need to provide additional syntax and use some more complex concepts. It is important to understand how these advanced transformations work when attempting to use them. The sections below outline some of the more advanced transformations and help you to use these with your own assets.

Remember, there are many more transformations available and you can find a full list of them, including examples, by checking out our URL transformation reference.

3D LUTs

3D lookup tables (3D LUTs) are used to map one color space to another. They can be used to adjust colors, contrast, and/or saturation, so that you can correct contrast, fix a camera’s inability to see a particular color shade, or give a final finished look or a particular style to your image.

After uploading a .3dl file to your account as a raw file, you can apply it to any image using the lut property of the layer parameter ( l_lut: in URLs), followed by the LUT file name (including the .3dl extension).

Below you can see the laydybug_top.jpg image file in its original color, compared to the video with different LUT files applied. Below these is the code for applying one of the LUTs.

Background color

Use the background parameter (b in URLs) to set the background color of the image. The image background is visible when padding is added with one of the padding crop modes, when rounding corners, when adding overlays, and with semi-transparent PNGs and GIFs.

An opaque color can be set as an RGB hex triplet (e.g., b_rgb:3e2222), a 3-digit RGB hex (e.g., b_rgb:777) or a named color (e.g., b_green). Cloudinary's client libraries also support a # shortcut for RGB (e.g., setting background to #3e2222 which is then translated to rgb:3e2222).

For example, the uploaded image named sample padded to a width and height of 300 pixels with a green background:

You can also use a 4-digit or 8-digit RGBA hex quadruplet for the background color, where the 4th hex value represents the alpha (opacity) value (e.g., co_rgb:3e222240 results in 25% opacity).

Note

When using the background parameter to set the background color of a text overlay, you can also set the color to predominant_contrast. This selects the strongest contrasting color to the predominant color while taking all pixels in the image into account. For example, l_text:Arial_30:foo,b_predominant_contrast.

See full syntax: b (background) in the Transformation Reference.

Content-aware padding

You can automatically set the background color to the most prominent color in the image when applying one of the padding crop modes (pad, lpad, or mpad) by setting the background parameter to auto (b_auto in URLs). The parameter can also accept an additional value as follows:

b_auto:border - selects the predominant color while taking only the image border pixels into account. This is the default option for b_auto.
b_auto:predominant - selects the predominant color while taking all pixels in the image into account.
b_auto:border_contrast - selects the strongest contrasting color to the predominant color while taking only the image border pixels into account.
b_auto:predominant_contrast - selects the strongest contrasting color to the predominant color while taking all pixels in the image into account.

b_auto:border

b_auto:predominant

b_auto:border_contrast

b_auto:predominant_contrast

For example, padding the sample image to a width and height of 300 pixels, and with the background color set to the predominant color in the image:

Gradient fade

You can also apply a padding gradient fade effect with the predominant colors in the image by adjusting the value of the b_auto parameter as follows:

b_auto:[gradient_type]:[number]:[direction]

Where:

gradient_type - one of the following values:
- predominant_gradient - base the gradient fade effect on the predominant colors in the image
- predominant_gradient_contrast - base the effect on the colors that contrast the predominant colors in the image
- border_gradient - base the gradient fade effect on the predominant colors in the border pixels of the image
- border_gradient_contrast - base the effect on the colors that contrast the predominant colors in the border pixels of the image
number - the number of predominant colors to select. Possible values: 2 or 4. Default: 2
direction - if 2 colors are selected, this parameter specifies the direction to blend the 2 colors together (if 4 colors are selected each gets interpolated between the four corners). Possible values: horizontal, vertical, diagonal_desc, and diagonal_asc. Default: horizontal

predominant_gradient:2:diagonal_desc

predominant_gradient_contrast:4

Custom color palette

Add a custom palette to limit the selected color to one of the colors in the palette that you provide. Once the predominant color has been calculated then the closest color from the available palette is selected. Append a colon and then the value palette followed by a list of colors, each separated by an underscore. For example, to automatically add padding and a palette that limits the possible choices to green, red and blue: b_auto:palette_red_green_blue

The palette can be used in combination with any of the various values for b_auto, and the same color in the palette can be selected more than once when requesting multiple predominant colors. For example, padding to a width and height of 300 pixels, with a 4 color gradient fade in the auto colored padding, and limiting the possible colors to red, green, blue, and orange:

Pad to 300x300 with 4 color gradient fade from given palette

Gradient fade into padding

Fade the image into the added padding by adding the gradient_fade effect with a value of symmetric_pad (e_gradient_fade:symmetric_pad in URLs). The padding blends into the edge of the image with a strength indicated by an additional value, separated by a colon (Range: 0 to 100, Default: 20). Values for x and y can also be specified as a percentage (range: 0.0 to 1.0), or in pixels (integer values) to indicate how far into the image to apply the gradient effect. By default, the gradient is applied 30% into the image (x_0.3).

For example, padding the sample image to a width and height of 300 pixels, with the background color set to the predominant color, and with a gradient fade effect, between the added padding and 50% into the image.

Borders

Add a solid border around images with the border parameter (bo in URLs). The parameter accepts a value with a CSS-like format: width_style_color (e.g., 3px_solid_black).

An opaque color can be set as an RGB hex triplet (e.g., rgb:3e2222), a 3-digit RGB hex (e.g., rgb:777) or a named color (e.g., green).

You can also use a 4-digit or 8-digit RGBA hex quadruplet for the color, where the 4th hex value represents the alpha (opacity) value (e.g., co_rgb:3e222240 results in 25% opacity).

Additionally, Cloudinary's client libraries also support a # shortcut for RGB (e.g., setting color to #3e2222 which is then translated to rgb:3e2222), and when using Cloudinary's client libraries, you can optionally set the border values programmatically instead of as a single string (e.g., :border => { :width => 4, :color => 'black' }).

Note

Currently only the 'solid' border style is supported.

Note

When using the border parameter to set the border color of a text overlay, you can also set the color to predominant_contrast. This selects the strongest contrasting color to the predominant color while taking all pixels in the image into account. For example, l_text:Arial_30:foo,bo_3px_solid_predominant_contrast

See full syntax: bo (border) in the Transformation Reference.

Color blind effects

Cloudinary has a number of features that can help you to choose the best images as well as to transform problematic images to ones that are more accessible to color blind people. You can use Cloudinary to:

Simulate how an image would look to people with different color blind conditions.
Assist people with color blind conditions to help differentiate problematic colors.
Analyze images to provide color blind accessibility scores and information on which colors are the hardest to differentiate.

Simulate color blind conditions

You can simulate a number of different color blind conditions using the simulate_colorblind effect. For full syntax and supported conditions, see the e_simulate_colorblind parameter in the Transformation URL API Reference.

Simulate the way an image would appear to someone with deuteranopia (most common form of) color blindness:

Displacement maps

You can displace pixels in a source image based on the intensity of pixels in a displacement map image using the e_displace effect in conjunction with a displacement map image specified as an overlay. This can be useful to create interesting effects in a select area of an image or to warp the entire image to fit a needed design or texture. For example, to make an image wrap around a coffee cup or appear to be printed on a textured canvas.

The displace effect (e_displace in URLs) algorithm displaces the pixels in an image according to the color channels of the pixels in another specified image (a gradient map specified with the overlay parameter). The displace effect is added in the same component as the layer_apply flag. The red channel controls horizontal displacement, green controls vertical displacement, and the blue channel is ignored. The final displacement of each pixel in the base image is determined by a combination of the red and green color channels, together with the configured x and/or y parameters. For example, for a given x value of 20 and a pixel with a red value of 255 (highest), the corresponding base image pixel would be displaced by 20 pixels horizontally, while a red value of 25 (10%) would only displace the base image pixel by 2 pixels horizontally.

This is a standard displacement map algorithm used by popular image editing tools, so you can upload existing displacement maps found on the internet or created by your graphic artists to your account and specify them as the overlay asset, enabling you to dynamically apply the displacement effect on other images in your account or those uploaded by your end users.

Several sample use-case of this layer-based effect are shown in the sections below.

See full syntax: e_displace in the Transformation Reference.

Use case: Warp an image to fit a 3-dimensional product

Use a displacement map to warp the perspective of an overlay image for final placement as an overlay on a mug:

Interactive texture demo

For more details on displacement mapping with the displace effect, see the article on Displacement Maps for Easy Image Transformations with Cloudinary. The article includes a variety of examples, as well as an interactive demo.

Distort

Using the distort effect, you can change the shape of an image, distorting its dimensions and the image itself. It works in one of two modes: you can either change the positioning of each of the corners, or you can warp the image into an arc.

To change the positioning of each of the corners, it is helpful to have in mind a picture like the one below. The solid rectangle shows the coordinates of the corners of the original image. The intended result of the distortion is represented by the dashed shape. The new corner coordinates are specified in the distort effect as x,y pairs, clockwise from top-left. For example:

For more details on perspective warping with the distort effect, see the article on How to dynamically distort images to fit your graphic design.

To curve an image, you can specify arc and the number of degrees in the distort effect, instead of the corner coordinates. If you specify a positive value for the number of degrees, the image is curved upwards, like a frown. Negative values curve the image downwards, like a smile.

You can distort text in the same way as images, for example, to add curved text to the frisbee image (e_distort:arc:-120):

Outline

The outline effect (e_outline in URLs) enables you to add an outline to your transparent images. The parameter can also be passed additional values as follows:

outline:[mode]:[width]:[blur]

mode - how to apply the outline effect which can be one of the following values: inner, inner_fill, outer, fill. Default value: inner and outer.
width - the first integer supplied applies to the thickness of the outline in pixels. Default value: 5. Range: 1 - 100
blur - the second integer supplied applies to the level of blur of the outline. Default value: 0. Range: 0 - 2000

Original

e_outline

e_outline:inner

e_outline:inner_fill

e_outline:outer

e_outline:fill

Use the color parameter (co in URLs) to define a new color for the outline (the default is black). The color can be specified as an RGB hex triplet (e.g., rgb:3e2222), a 3-digit RGB hex (e.g., rgb:777) or a named color (e.g., green). For example, to add an orange outline:

Replace color

You can replace a color in an image using the replace_color effect. Unless you specify otherwise, the most prominent high-saturation color in an image is selected as the color to change. By default, a tolerance of 50 is applied to this color, representing a radius in the LAB color space, so that similar shades are also replaced, achieving a more natural effect.

For example, without specifying a color to change, the most prominent color is changed to the specified maroon:

Blues recolored to maroon shades

See full syntax: e_replace_color in the Transformation Reference.

Rotation

Rotate an image by any arbitrary angle in degrees with the angle parameter (a in URLs). A positive integer value rotates the image clockwise, and a negative integer value rotates the image counterclockwise. If the angle is not a multiple of 90 then a rectangular bounding box is added containing the rotated image and empty space.

Note

If either the width or height of an image exceeds 3000 pixels, the image is automatically downscaled first, and then rotated. This applies to the image that is the input to the rotation, be it the output of a chained transformation or the original image.

Other possible rotation values instead of an integer value include:

auto_right - Rotate the image 90 degrees clockwise only if the requested aspect ratio does not match the image's aspect ratio.
auto_left - Rotate the image 90 degrees counterclockwise only if the requested aspect ratio does not match the image's aspect ratio.
vflip - Vertical mirror flip of the image.
hflip - Horizontal mirror flip of the image.
ignore - By default, the image is automatically rotated according to the EXIF data stored by the camera when the image was taken. Set the rotation to 'ignore' if you do not want the image to be automatically rotated.

Note

To apply multiple values, separate each value with a dot (.). For example to horizontally flip the image and rotate it by 45 degrees: angle: hflip.45

Examples with the uploaded image named sample (all images are also scaled down to a width of 100 pixels):
