5
- * Converts to and from JSON format.
6
- *
7
- * JSON (JavaScript Object Notation) is a lightweight data-interchange
8
- * format. It is easy for humans to read and write. It is easy for machines
9
- * to parse and generate. It is based on a subset of the JavaScript
10
- * Programming Language, Standard ECMA-262 3rd Edition - December 1999.
11
- * This feature can also be found in Python. JSON is a text format that is
12
- * completely language independent but uses conventions that are familiar
13
- * to programmers of the C-family of languages, including C, C++, C#, Java,
14
- * JavaScript, Perl, TCL, and many others. These properties make JSON an
15
- * ideal data-interchange language.
16
- *
17
- * This package provides a simple encoder and decoder for JSON notation. It
18
- * is intended for use with client-side Javascript applications that make
19
- * use of HTTPRequest to perform server communication functions - data can
20
- * be encoded into JSON notation for use in a client-side javascript, or
21
- * decoded from incoming Javascript requests. JSON format is native to
22
- * Javascript, and can be directly eval()'ed with no further parsing
23
- * overhead
24
- *
25
- * All strings should be in ASCII or UTF-8 format!

48
-
49
- == Frequently Asked Questions ==
50
-
51
- = Should I pick lossy or losssless optimisation =
52
-
53
- This depends on your compression needs. Lossy has a better compression rate than lossless compression.
54
- The resulting image is not 100% identical with the original. Works well for photos taken with your camera.
55
-
56
- With lossless compression, the shrunk image will be identical with the original and smaller in size.
57
- Use this when you do not want to loose any of the original image's details. Works best for technical drawings, clip art and comics.
58
-
59
-
60
- = Is my privacy ensured, are all my images safe? =
61
-
62
- Yes, privacy is guaranteed. The ShortPixel automated encription process doesn't allow anyone to view your photos.
