ZplGraphicDecoder
public static class ZplGraphicDecoderDecodes ZPL graphic data (^GF, ~DG, ~DY) into a 1-bit-per-pixel byte array (MSB first, 1 = black). Supports ASCII hex incl. Zebra run-length compression, :Z64: (zlib+base64), :B64: and raw binary.
Methods
| Method Signature | Returns | Description |
|---|---|---|
static # Decode(string data, int bytesPerRow, int totalBytes) | byte[] | Decodes graphic data without a size limit (trusted input only). |
static # Decode(string data, int bytesPerRow, int totalBytes, int maxBytes) | byte[] | Decodes graphic data. Never throws for malformed data (invalid base64/zlib yields an empty/zero-padded result). data: Field data: hex (optionally ZPL-compressed), :Z64: or :B64:. · bytesPerRow: Bytes per graphic row. · totalBytes: Total number of graphic bytes. · maxBytes: Upper bound for the decoded size (incl. totalBytes and zlib output); exceeding it throws InvalidDataException. 0 = unlimited. |
static # DecodeAsciiHex(string data, int bytesPerRow, int totalBytes) | byte[] | ASCII hex with ZPL compression: G..Y = repeat 1..19, g..z = repeat 20..400 (step 20), ',' = rest of row 0, '!' = rest of row 1, ':' = repeat previous row. Counts apply to the following hex nibble. |
static # DecodeAsciiHex(string data, int bytesPerRow, int totalBytes, int maxBytes) | byte[] | |
static # DecodeBinary(string data, int totalBytes) | byte[] | Binary (format B) data as it appears in the ZPL string (Latin-1 chars → bytes). |
static # DecodeBinary(string data, int totalBytes, int maxBytes) | byte[] | |
static # EncodeAsciiHex(byte[] data) | string | Encodes a 1bpp buffer as uncompressed ASCII hex (for ^GFA output). |
static # EncodeZ64(byte[] data) | string | Encodes a 1bpp buffer as :Z64: with CRC16 (CCITT, as used by Zebra). |
