<script type="module">
    import { appendDefaultEditor } from './pintura.js';

    const editor = appendDefaultEditor('#editor', { src: 'image.jpeg' });
</script>

imageOrienter

Can be set to a helper object to correctly orient image data. This is useful for older browsers where interpretation of the EXIF orientation header is done incorrectly and images appear upside down or mirrored.

The property expects an object with an read and an apply function.

  • The read function is used to read the EXIF orientation header from the image preview data.
  • The apply function is used to apply the EXIF orientation header to the image preview.

We can import the createDefaultImageOrienter method and use it to set the imageOrienter property to automatically orient images.

When using one of the default editor factories this property is set automatically.

    setPlugins(plugin_crop);

    const editor = appendEditor('#editor', {
        imageReader: createDefaultImageReader(),
        imageWriter: createDefaultImageWriter(),
        imageOrienter: createDefaultImageOrienter(),
        locale: {

            ...plugin_crop_locale_en_gb,
        },
        src: 'image.jpeg',
    });
</script>

imageReader

Expects an array of read steps to step through when reading the src input image data.

We can import the createDefaultImageReader method and use it to set the imageReader property to read preview images.

<!DOCTYPE html>

<head>
    <link rel="stylesheet" href="./pintura.css" />

<style>
    .pintura-editor {
        height: 600px;
    }
</style>

<div id="editor"></div>

<script type="module">
    import {
        appendEditor,
        createDefaultImageReader,
        createDefaultImageWriter,
        createDefaultImageOrienter,
        setPlugins,
        plugin_crop,
        locale_en_gb,
        plugin_crop_locale_en_gb,
    } from './pintura.js';

    setPlugins(plugin_crop);

    const editor = appendEditor('#editor', {
        imageReader: createDefaultImageReader({ orientImage: true }),
        imageWriter: createDefaultImageWriter(),
        imageOrienter: createDefaultImageOrienter(),
        locale: {
            ...locale_en_gb,
            ...plugin_crop_locale_en_gb,
        },
        src: 'image.jpeg',
    });
</script>

The imageReader property has to be set for the editor to be able to show image previews, without it the editor won't run.

When using the default editor factories we don't have to set this property as it's set automatically.

If we want to pass different configuration options we can set them to the property directly.

<!DOCTYPE html>

<head>
    <link rel="stylesheet" href="./pintura.css" />

    .pintura-editor {
        height: 600px;

    const editor = appendDefaultEditor('#editor', {
        src: 'image.jpeg',
        imageReader: { orientImage: true },
    });
</script>

imageWriter

Expects an array of write steps to step through when writing the output image data.

We can import the createDefaultImageWriter method and use it to set the imageWriter property to write output images.

<!DOCTYPE html>

<head>
    <link rel="stylesheet" href="./pintura.css" />
</head>

<style>
    .pintura-editor {
        height: 600px;
    }
</style>

<div id="editor"></div>

<script type="module">
    import {
        appendEditor,
        createDefaultImageReader,
        createDefaultImageWriter,
        createDefaultImageOrienter,
        setPlugins,
        plugin_crop,
        locale_en_gb,
        plugin_crop_locale_en_gb,
    } from './pintura.js';

    setPlugins(plugin_crop);

    const editor = appendEditor('#editor', {
        imageReader: createDefaultImageReader(),
        imageWriter: createDefaultImageWriter({ quality: 0.5 }),
        imageOrienter: createDefaultImageOrienter(),
        locale: {
            ...locale_en_gb,
            ...plugin_crop_locale_en_gb,
        },
        src: 'image.jpeg',
    });
</script>

If we don't need to output image data, for example when we're only storing the original image and the editor state, we don't have to set the imageWriter property.

When using the default editor factories we don't have to set this property as it's automatically defined.

If we want to pass different configuration options we can set them to the property directly.

<!DOCTYPE html>

<script type="module">
    import {
        appendEditor,
        createDefaultImageReader,
        createDefaultImageOrienter,
        setPlugins,
        plugin_crop,
        locale_en_gb,
        plugin_crop_locale_en_gb,
    } from './pintura.js';

    setPlugins(plugin_crop);

    const editor = appendEditor('#editor', {
        imageReader: createDefaultImageReader(),
        imageWriter: { quality: 0.5 },
        imageOrienter: createDefaultImageOrienter(),
        locale: {

            ...plugin_crop_locale_en_gb,
        },
        src: 'image.jpeg',
    });
</script>

imageScrambler

Set to a function that can receive an ImageData or ImageBitmap object, should return scrambled ImageData or an HTMLCanvasElement. Used with the imageRedaction property and createDefaultImageScrambler function to redact information in an image.

<!DOCTYPE html>

<head>
    <link rel="stylesheet" href="./pintura.css" />
</head>

<style>
    .pintura-editor {
        height: 600px;
    }
</style>

<div id="editor"></div>

<script type="module">
    import { appendDefaultEditor } from './pintura.js';

    const editor = appendDefaultEditor('#editor', {
        src: 'image.jpeg',
        imageScrambler: (data) =>
            new Promise((resolve) => {
                // Receives current image as ImageData or ImageBitmap

                // Blur here, advise is to return an image with smaller dimensions

                // Resolves with blurred ImageData or HTMLCanvasElement
                resolve(imageData);
            }),
    });
</script>

We can import the createDefaultImageScrambler function and use it to set the imageScrambler property to handle scrambling the image data for us.

<!DOCTYPE html>

<head>
    <link rel="stylesheet" href="./pintura.css" />
</head>

<style>
    .pintura-editor {

        appendDefaultEditor,
        createDefaultImageScrambler,
    } from './pintura.js';

    const editor = appendDefaultEditor('#editor', {
        src: 'image.jpeg',
        imageScrambler: createDefaultImageScrambler({ scrambleAmount: 2 }),
    });
</script>

When using the default editor factories we don't have to set this property as it's automatically defined.

If we want to pass different configuration options we can set them to the property directly.

    const editor = appendDefaultEditor('#editor', {
        src: 'image.jpeg',
        imageScrambler: { scrambleAmount: 2 },
    });
</script>

shapePreprocessor

The preprocessor used to render composit shapes like lineEnd styles and frames. Use createDefaultShapePreprocessor to set the default preprocessor.

Use createShapePreprocessor to create a custom shape preprocessor.

When using the default editor factories we don't have to set this property as it's automatically defined. We can however set it to a custom shape preprocessor which will then automatically be added to the shape preprocessor list.

If we don't use lineEnd styles and frame styles we don't need a shapePreprocessor and we can leave this property undefined.

        },
        src: 'image.jpeg',
        shapePreprocessor: createDefaultShapePreprocessor(),
    });
</script>

            // custom shape preprocessor
            (shape, options) => {
                // process shape here
            },

            // another custom shape preprocessor
        ],
    });
</script>

imageCrop

The current crop rectangle is relative to the (optionally rotated) bounding box of the image.

In the diagram below we can see how this works. We've defined a 64 x 64 crop in the top left corner of the image.

  • The dashed line illustrates the bounding box of the rotated image.
  • The magenta square represents our 64 × 64 crop positioned relative to the image bounding box.

We can see how the crop rectangle updates when we rotate the image using the range input.

If we assign options to the editor creation command the crop will be set first and then the rotation. In the example below, no matter the order of the properties, the crop will be set first and then the image will be rotated.

            width: 64,
            height: 64,

    buttonRotateImage.addEventListener('click', () => {
        editor.imageRotation += Math.PI / 4;
    });
</script>

imageCropAspectRatio

Set the aspect ratio of the crop as a number.

When not set, it defaults to undefined meaning a crop aspect ratio won't be enforced.

        imageCropAspectRatio: 16 / 9,
    });

imageCropMinSize

A Size describing The minimum size of the crop. Defaults to { width: 1, height: 1 }. Pintura will prevent loading smaller images.

imageCropMaxSize

A Size describing The maximum size of the crop. Defaults to { width: 32768, height: 32768 }.

imageFlipX

    buttonFlipImage.addEventListener('click', () => {
        editor.imageFlipY = !editor.imageFlipY;
    });
</script>

imageTargetSize

A size { width: number, height: number } describing the output size of the image, this value is visible in the Resize plugin input fields.

If you want all images to be resized to a certain size it's better to use the targetSize property on the imageWriter to set a size that is invisible to the user.

imageCropLimitToImage

Defaults to true, when set to true Pintura Image Editor will prevent cropping outside of

When set to false we can make a crop outside of the image edges. This also means we can zoom out further and rotate the image without auto zoom. To control the background color of pixels outside of the image we can set the imageBackgroundColor prop.

imageRedaction

Set to an array of rectangular shapes to redact parts of the image. If the image is rotated or flipped, the redactions rotate and flip with the image.

See the updating shapes section on how to add, remove or update redaction shapes.

imageAnnotation

Set to an array of shapes to draw them in the image context. If the image is rotated or flipped, the shapes rotate and flip with the image.

See the updating shapes section on how to add, remove or update shapes.

imageDecoration

Set to an array of shapes to draw them in the crop context. If the image is rotated or flipped, the shapes stay where they are. If the crop rectangle is changed, the shape positions are updated as well.

See the updating shapes section on how to add, remove or update shapes.

imageFrame

Can be set to a frameStyle to select an initial frame style.

When using frames we need to set the shapePreprocessor property, either set the defaults or define your own custom frame styles.

            frameColor: [1, 1, 1],
        },
    });
</script>

imageColorMatrix

A color matrix to apply to the image. The imageColorMatrix property contains multiple color matrices for both the filter settings and finetune color settings.

To set a custom color matrix, assign it like shown below.

                ],
        },
    });
</script>

imageGamma

The image gamma adjustment, a value between 0.15 and 4.

imageVignette

The vignette to apply to the image, a value between -1 and 1, a positive value indicating a dark vignette and a negative value a bright vignette.

imageBackgroundColor

    const editor = appendDefaultEditor('#editor', {

</script>

Transparent background colors are supported for the output image but at the moment the image rendering in the editor itself isn't fully accurate.

imageBackgroundImage

Set to a background image to render behind the crop. Accepts the same source types as the image src property.

The image will be centered and scaled to cover the output image dimensions.

imageMinDuration

The minimum required duration for video files.

Will be renamed to mediaMinDuration in the next major release.

imageMaxDuration

The maximum required duration for video files. This will not prevent loading longer files, the Trim plugin will prevent outputing longer files by limiting the clip length.

Will be renamed to mediaMaxDuration in the next major release.

imageState

The imageState property describes the current image state.

You can pass the imageState object to the loadImage method or store it and later use it to set the imageState to restore a previous state. The imageState is also returned after processing an image.

An example imageState object is shown below.
