bmp-js
|
||||
======
|
||||
|
||||
A pure javascript Bmp encoder and decoder for node.js
|
||||
|
||||
Supports 1bit 4bit 8bit 24bit decoding and encoding with 24bit.
|
||||
|
||||
##Install
|
||||
|
||||
$ npm install bmp-js
|
||||
|
||||
|
||||
How to use?
|
||||
---
|
||||
###Decode BMP
|
||||
```js
|
||||
var bmp = require("bmp-js");
|
||||
var bmpBuffer = fs.readFileSync('aa.bmp');
|
||||
var bmpData = bmp.decode(bmpBuffer);
|
||||
//bmpData={data:Buffer,width:Number,height:Height}
|
||||
|
||||
```
|
||||
|
||||
###Encode RGB
|
||||
```js
|
||||
var bmp = require("bmp-js");
|
||||
//bmpData={data:Buffer,width:Number,height:Height}
|
||||
var rawData = bmp.encode(bmpData);//default no compression
|
||||
|
||||
```

# file-type [](https://travis-ci.org/sindresorhus/file-type)
|
||||
|
||||
> Detect the file type of a Buffer/Uint8Array
|
||||
|
||||
The file type is detected by checking the [magic number](http://en.wikipedia.org/wiki/Magic_number_(programming)#Magic_numbers_in_files) of the buffer.
|
||||
|
||||
|
||||
## Install
|
||||
|
||||
```
|
||||
$ npm install --save file-type
|
||||
```
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
##### Node.js
|
||||
|
||||
```js
|
||||
const readChunk = require('read-chunk'); // npm install read-chunk
|
||||
const fileType = require('file-type');
|
||||
const buffer = readChunk.sync('unicorn.png', 0, 262);
|
||||
|
||||
fileType(buffer);
|
||||
//=> {ext: 'png', mime: 'image/png'}
|
||||
```
|
||||
|
||||
or from a remote location:
|
||||
|
||||
```js
|
||||
const http = require('http');
|
||||
const fileType = require('file-type');
|
||||
const url = 'http://assets-cdn.github.com/images/spinners/octocat-spinner-32.gif';
|
||||
|
||||
http.get(url, res => {
|
||||
res.once('data', chunk => {
|
||||
res.destroy();
|
||||
console.log(fileType(chunk));
|
||||
//=> {ext: 'gif', mime: 'image/gif'}
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
##### Browser
|
||||
|
||||
```js
|
||||
const xhr = new XMLHttpRequest();
|
||||
xhr.open('GET', 'unicorn.png');
|
||||
xhr.responseType = 'arraybuffer';
|
||||
|
||||
xhr.onload = () => {
|
||||
fileType(new Uint8Array(this.response));
|
||||
//=> {ext: 'png', mime: 'image/png'}
|
||||
};
|
||||
|
||||
xhr.send();
|
||||
```
|
||||
|
||||
|
||||
## API
|
||||
|
||||
### fileType(buffer)
|
||||
|
||||
Returns an `Object` (or `null` when no match) with:
|
||||
|
||||
- `ext` - one of the [supported file types](#supported-file-types)
|
||||
- `mime` - the [MIME type](http://en.wikipedia.org/wiki/Internet_media_type)
|
||||
|
||||
#### buffer
|
||||
|
||||
Type: `Buffer` `Uint8Array`
|
||||
|
||||
It only needs the first 262 bytes.
|
||||

> Get a stream as a string, buffer, or array
|

|

```
|

|

|
||||
const getStream = require('get-stream');
|
||||
const stream = fs.createReadStream('unicorn.txt');
|

|
||||
`\_| (,~~
|
||||
\~\
|
||||
~~
|
||||
*/
|
||||
});
|
||||
```
|
||||
|
||||
|
||||
## API
|
||||
|
||||
The methods returns a promise that is resolved when the `end` event fires on the stream, indicating that there is no more data to be read. The stream is switched to flowing mode.
|
||||
|
||||
### getStream(stream, [options])
|
||||
|
||||
Get the `stream` as a string.
|
||||
|
||||
#### options
|
||||
|
||||
##### encoding
|
||||
|
||||
Type: `string`<br>
|
||||
Default: `utf8`
|
||||
|
||||
[Encoding](https://nodejs.org/api/buffer.html#buffer_buffer) of the incoming stream.
|
||||
|
||||
##### maxBuffer
|
||||
|
||||
Type: `number`<br>
|
||||
Default: `Infinity`
|
||||
|
||||
Maximum length of the returned string. If it exceeds this value before the stream ends, the promise will be rejected.
|
||||
|
||||
### getStream.buffer(stream, [options])
|
||||
|
||||
Get the `stream` as a buffer.
|
||||
|
||||
It honors the `maxBuffer` option as above, but it refers to byte length rather than string length.
|
||||
|
||||
### getStream.array(stream, [options])
|
||||
|
||||
Get the `stream` as an array of values.
|
||||
|
||||
It honors both the `maxBuffer` and `encoding` options. The behavior changes slightly based on the encoding chosen:
|
||||
|
||||
- When `encoding` is unset, it assumes an [object mode stream](https://nodesource.com/blog/understanding-object-streams/) and collects values emitted from `stream` unmodified. In this case `maxBuffer` refers to the number of items in the array (not the sum of their sizes).
|
||||
|
||||
- When `encoding` is set to `buffer`, it collects an array of buffers. `maxBuffer` refers to the summed byte lengths of every buffer in the array.
|
||||
|
||||
- When `encoding` is set to anything else, it collects an array of strings. `maxBuffer` refers to the summed character lengths of every string in the array.
|
||||
|
||||
|
||||
## Errors
|
||||
|
||||
If the input stream emits an `error` event, the promise will be rejected with the error. The buffered data will be attached to the `bufferedData` property of the error.
|
||||
|
||||
```js
|
||||
getStream(streamThatErrorsAtTheEnd('unicorn'))
|
||||
.catch(err => console.log(err.bufferedData));
|
||||
// unicorn
|
||||
```
|
||||
|
||||
|
||||
## FAQ
|
||||
|
||||
### How is this different from [`concat-stream`](https://github.com/maxogden/concat-stream)?
|
||||
|
||||
This module accepts a stream instead of being one and returns a promise instead of using a callback. The API is simpler and it only supports returning a string, buffer, or array. It doesn't have a fragile type inference. You explicitly choose what you want. And it doesn't depend on the huge `readable-stream` package.

# jpeg-js
|
||||
|
||||
A pure javascript JPEG encoder and decoder for node.js
|
||||
|
||||
[](http://travis-ci.org/eugeneware/jpeg-js)
|
||||
|
||||
## Installation
|
||||
|
||||
This module is installed via npm:
|
||||
|
||||
``` bash
|
||||
$ npm install jpeg-js
|
||||
```
|
||||
|
||||
## Example Usage
|
||||
|
||||
### Decoding JPEGs
|
||||
|
||||
``` js
|
||||
var jpegData = fs.readFileSync('grumpycat.jpg');
|
||||
var rawImageData = jpeg.decode(jpegData);
|
||||
```
|
||||
|
||||
### Encoding JPEGs
|
||||
|
||||
``` js
|
||||
var width = 320, height = 180;
|
||||
var frameData = new Buffer(width * height * 4);
|
||||
var i = 0;
|
||||
while (i < frameData.length) {
|
||||
frameData[i++] = 0xFF; // red
|
||||
frameData[i++] = 0x00; // green
|
||||
frameData[i++] = 0x00; // blue
|
||||
frameData[i++] = 0xFF; // alpha - ignored in JPEGs
|
||||
}
|
||||
var rawImageData = {
|
||||
data: frameData,
|
||||
width: width,
|
||||
height: height
|
||||
};
|
||||
var jpegImageData = jpeg.encode(rawImageData, 50);
|
||||
```
|
||||
|
||||

|
||||
|
||||
### Decoding
|
||||
|
||||
This library builds on the work of two other JPEG javascript libraries,
|
||||
namely [jpgjs](https://github.com/notmasteryet/jpgjs) for the decoding
|
||||
which is licensed under the Apache 2.0 License below:

|
||||
|
||||
### Encoding
|
||||
|
||||
The encoding is based off a port of the JPEG encoder in [as3corelib](https://code.google.com/p/as3corelib/source/browse/trunk/src/com/adobe/images/JPGEncoder.as).
|
||||
|
||||
The port to Javascript was done by by Andreas Ritter, www.bytestrom.eu, 11/2009.
