Decode (Function)

In french: Decode

Decodes a character string that was encoded by Encode.

Example

// Encode an image in base64
Res is string = Encode(fLoadBuffer("MyImage.jpg"), encodeBASE64)

// ...

// Decode the image
DecodedImage is Image = Decode(Res, encodeBASE64)

// Decode a buffer received in an HTTP request
bufRead is Buffer = HTTPResponse..Content
<COMPILE IF UNICODEConfiguration>
bufResult = Decode(AnsiToUnicode(bufRead), encodeBASE64)
<ELSE>
bufResult = Decode(bufRead, encodeBASE64)
<END>

Syntax

<Result> = Decode(<Element to decode> [, <Encoding/decoding format>])

<Result>: Character string or Buffer

Result of decoding.

<Element to decode>: Character string

Data to decode. This data was encoded by Encode.
Caution: The string to decode must be in the same format as the default strings of the project: ANSI or UNICODE.

<Encoding/decoding format>: Integer constant

Specifies the type of encoding performed. This parameter must be identical to the one chosen during the coding.
encodeBASE64
(Default value) BASE 64 format (complies with the RFC 4648 standard). Encoded text contains only printable characters and CRs (Carriage Returns).
Versions 25 and later
encodeBASE64NoCR
New in version 25
encodeBASE64NoCR
encodeBASE64NoCR BASE 64 format (complies with RFC 4648 standard) without RCs (Carriage Returns). The encoded text contains printable characters only.
encodeBASE64URL BASE 64 URL format (complies with the RFC 4648 standard). The encoded text contains printable characters only.
encodeBASE85 BASE 85 format. The encoded text contains printable characters only.
encodePCS ASCII format. The encoded text contains printable characters only.
encodeURLToAnsi URL format. The encoded text only contains characters allowed in a URL. The decoded text is an ANSI string. This constant corresponds to the encodeURLFromAnsi constant used in Encode.
encodeURLToUTF8 URL format. The encoded text only contains characters allowed in a URL. The decoded text is a UTF-8 string. This constant corresponds to the encodeURLFromUTF8 constant used in Encode.
encodeURLToUnicode URL format. The encoded text only contains characters allowed in a URL. The decoded text is a Unicode string. This constant corresponds to the encodeURLFromUnicode constant used in Encode.
encodeUUEncode UUEncode format. The encoded text contains printable characters only.

Remarks

Format of character strings to decode

The string to decode must be in the same format as the default strings of the current project configuration: ANSI or UNICODE.

To know or modify the default string format:

Open the description window of the current configuration: on the "Project" pane, in the "Project configuration" group, click "Current configuration".
The "Unicode" tab allows you to know which type of character strings is used by default.
