@mbtech-nl/bitmap / iterRows

Function: iterRows()

function iterRows(bitmap: LabelBitmap): Generator<Uint8Array>;

Defined in: encode.ts:44

Iterate packed rows of a bitmap top-to-bottom.

Yields zero-copy Uint8Array views over the bitmap's underlying buffer (subarrays, not copies). Mutating a yielded row mutates the bitmap. Use for streaming a bitmap to a printer or encoder line-by-line without allocating per row.

Parameters

Parameter	Type	Description
bitmap	LabelBitmap	Source bitmap.

Returns

Generator<Uint8Array>

Example

for (const row of iterRows(bitmap)) {
  await transport.write(row);
}
