常用示例
Encode text as Data Matrix barcode
echo "[text]" | dmtxwrite -o [output.png]
Create barcode from file contents
dmtxwrite -o [output.png] < [data.txt]
Set module (cell) size in pixels
echo "[text]" | dmtxwrite -d [5] -o [output.png]
Set margin size in pixels
echo "[text]" | dmtxwrite -m [10] -o [output.png]
Create SVG output
echo "[text]" | dmtxwrite -o [output.svg]
Use specific symbol size
echo "[text]" | dmtxwrite -s s -o [output.png]
Print codeword listing instead of barcode
echo "[text]" | dmtxwrite -c
Set image print resolution (DPI)
echo "[text]" | dmtxwrite -R [300] -o [output.png]
说明
dmtxwrite generates Data Matrix barcode images from input text or binary data. Data Matrix barcodes are 2D square or rectangular patterns that encode data with built-in error correction. The tool reads data from standard input and produces images in various formats. Symbol size is automatically chosen based on data length, or can be specified manually. Error correction is automatically included per the Data Matrix standard. Data Matrix barcodes are widely used for small item marking (electronics, medical devices), logistics, and anywhere high data density is needed in a small space.
