)).
+
+The `loadImage()` function applies options using
+[progressive enhancement](https://en.wikipedia.org/wiki/Progressive_enhancement)
+and falls back to a configuration that is supported by the browser, e.g. if the
+`canvas` element is not supported, an equivalent `img` element is returned.
## API
+### Callback
+
+#### Function signature
+
The `loadImage()` function accepts a
-[File](https://developer.mozilla.org/en/DOM/File) or
-[Blob](https://developer.mozilla.org/en/DOM/Blob) object or a simple image URL
-(e.g. `'https://example.org/image.png'`) as first argument.
-
-If a [File](https://developer.mozilla.org/en/DOM/File) or
-[Blob](https://developer.mozilla.org/en/DOM/Blob) is passed as parameter, it
-returns a HTML `img` element if the browser supports the
-[URL](https://developer.mozilla.org/en/DOM/window.URL) API or a
-[FileReader](https://developer.mozilla.org/en/DOM/FileReader) object if
-supported, or `false`.
-It always returns a HTML
-[img](https://developer.mozilla.org/en/docs/HTML/Element/Img) element when
-passing an image URL:
+[File](https://developer.mozilla.org/en-US/docs/Web/API/File) or
+[Blob](https://developer.mozilla.org/en-US/docs/Web/API/Blob) object or an image
+URL as first argument.
+
+If a [File](https://developer.mozilla.org/en-US/docs/Web/API/File) or
+[Blob](https://developer.mozilla.org/en-US/docs/Web/API/Blob) is passed as
+parameter, it returns an HTML `img` element if the browser supports the
+[URL](https://developer.mozilla.org/en-US/docs/Web/API/URL) API, alternatively a
+[FileReader](https://developer.mozilla.org/en-US/docs/Web/API/FileReader) object
+if the `FileReader` API is supported, or `false`.
+
+It always returns an HTML
+[img](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Img) element
+when passing an image URL:
```js
-document.getElementById('file-input').onchange = function (e) {
- var loadingImage = loadImage(
- e.target.files[0],
- function (img) {
- document.body.appendChild(img)
- },
- { maxWidth: 600 }
- )
- if (!loadingImage) {
- // Alternative code ...
- }
-}
+var loadingImage = loadImage(
+ 'https://example.org/image.png',
+ function (img) {
+ document.body.appendChild(img)
+ },
+ { maxWidth: 600 }
+)
```
-The `img` element or
-[FileReader](https://developer.mozilla.org/en/DOM/FileReader) object returned by
-the `loadImage()` function allows to abort the loading process by setting the
-`onload` and `onerror` event handlers to null:
+#### Cancel image loading
+
+Some browsers (e.g. Chrome) will cancel the image loading process if the `src`
+property of an `img` element is changed.
+To avoid unnecessary requests, we can use the
+[data URL](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs)
+of a 1x1 pixel transparent GIF image as `src` target to cancel the original
+image download.
+
+To disable callback handling, we can also unset the image event handlers and for
+maximum browser compatibility, cancel the file reading process if the returned
+object is a
+[FileReader](https://developer.mozilla.org/en-US/docs/Web/API/FileReader)
+instance:
```js
-document.getElementById('file-input').onchange = function (e) {
- var loadingImage = loadImage(
- e.target.files[0],
- function (img) {
- document.body.appendChild(img)
- },
- { maxWidth: 600 }
- )
+var loadingImage = loadImage(
+ 'https://example.org/image.png',
+ function (img) {
+ document.body.appendChild(img)
+ },
+ { maxWidth: 600 }
+)
+
+if (loadingImage) {
+ // Unset event handling for the loading image:
loadingImage.onload = loadingImage.onerror = null
+
+ // Cancel image loading process:
+ if (loadingImage.abort) {
+ // FileReader instance, stop the file reading process:
+ loadingImage.abort()
+ } else {
+ // HTMLImageElement element, cancel the original image request by changing
+ // the target source to the data URL of a 1x1 pixel transparent image GIF:
+ loadingImage.src =
+ 'data:image/gif;base64,' +
+ 'R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7'
+ }
}
```
-The second argument must be a `callback` function, which is called when the
-image has been loaded or an error occurred while loading the image. The callback
-function is passed two arguments.
-The first is either an HTML `img` element, a
-[canvas](https://developer.mozilla.org/en/HTML/Canvas) element, or an
-[Event](https://developer.mozilla.org/en/DOM/event) object of type `error`.
-The second is on object with the original image dimensions as properties and
-potentially additional [meta data](#meta-data-parsing):
+**Please note:**
+The `img` element (or `FileReader` instance) for the loading image is only
+returned when using the callback style API and not available with the
+[Promise](#promise) based API.
+
+#### Callback arguments
+
+For the callback style API, the second argument to `loadImage()` must be a
+`callback` function, which is called when the image has been loaded or an error
+occurred while loading the image.
+
+The callback function is passed two arguments:
+
+1. An HTML [img](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/img)
+ element or
+ [canvas](https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API)
+ element, or an
+ [Event](https://developer.mozilla.org/en-US/docs/Web/API/Event) object of
+ type `error`.
+2. An object with the original image dimensions as properties and potentially
+ additional [metadata](#metadata-parsing).
+
+```js
+loadImage(
+ fileOrBlobOrUrl,
+ function (img, data) {
+ document.body.appendChild(img)
+ console.log('Original image width: ', data.originalWidth)
+ console.log('Original image height: ', data.originalHeight)
+ },
+ { maxWidth: 600, meta: true }
+)
+```
+
+**Please note:**
+The original image dimensions reflect the natural width and height of the loaded
+image before applying any transformation.
+For consistent values across browsers, [metadata](#metadata-parsing) parsing has
+to be enabled via `meta:true`, so `loadImage` can detect automatic image
+orientation and normalize the dimensions.
+
+#### Error handling
+
+Example code implementing error handling:
```js
-var imageUrl = 'https://example.org/image.png'
loadImage(
- imageUrl,
+ fileOrBlobOrUrl,
function (img, data) {
if (img.type === 'error') {
- console.error('Error loading image ' + imageUrl)
+ console.error('Error loading image file')
} else {
document.body.appendChild(img)
- console.log('Original image width: ', data.originalWidth)
- console.log('Original image height: ', data.originalHeight)
}
},
{ maxWidth: 600 }
)
```
+### Promise
+
+If the `loadImage()` function is called without a `callback` function as second
+argument and the
+[Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise)
+API is available, it returns a `Promise` object:
+
+```js
+loadImage(fileOrBlobOrUrl, { maxWidth: 600, meta: true })
+ .then(function (data) {
+ document.body.appendChild(data.image)
+ console.log('Original image width: ', data.originalWidth)
+ console.log('Original image height: ', data.originalHeight)
+ })
+ .catch(function (err) {
+ // Handling image loading errors
+ console.log(err)
+ })
+```
+
+The `Promise` resolves with an object with the following properties:
+
+- `image`: An HTML
+ [img](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/img) or
+ [canvas](https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API) element.
+- `originalWidth`: The original width of the image.
+- `originalHeight`: The original height of the image.
+
+Please also read the note about original image dimensions normalization in the
+[callback arguments](#callback-arguments) section.
+
+If [metadata](#metadata-parsing) has been parsed, additional properties might be
+present on the object.
+
+If image loading fails, the `Promise` rejects with an
+[Event](https://developer.mozilla.org/en-US/docs/Web/API/Event) object of type
+`error`.
+
## Options
-The optional third argument to `loadImage()` is a map of options.

+loading.

-// a transform stream is a readable/writable stream where you do
-// something with the data. Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored. (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation. For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes. When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up. When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer. When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks. If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk. However,
-// a pathological inflate type of transform can cause excessive buffering
-// here. For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output. In this case, you could write a very small
-// amount of input, and end up with a very large amount of output. In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform. A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.
