public QrPixelDecodeOptions WithAggressiveSampling(Boolean enabled = true) #Returns:
QrPixelDecodeOptionsEnables or disables aggressive sampling.
Parameters
- enabled System.Boolean = true
public QrPixelDecodeOptions WithAutoCrop(Boolean enabled = true) #Returns:
QrPixelDecodeOptionsEnables or disables auto-crop for QR decoding.
Parameters
- enabled System.Boolean = true

QrPixelDecodeOptionsSets the time+dimension budget in one call.
Parameters
- maxMilliseconds System.Int32
- maxDimension System.Int32 = 0
public QrPixelDecodeOptions WithBudgetMilliseconds(Int32 maxMilliseconds) #Returns:
QrPixelDecodeOptionsSets a hard decode time budget without profile downgrades.
Parameters
- maxMilliseconds System.Int32
public QrPixelDecodeOptions WithMaxDimension(Int32 maxDimension) #Returns:
QrPixelDecodeOptionsSets maximum dimension (pixels) for QR decoding.
Parameters

Properties
public QrDecodeProfile Profile { get; set; } #Speed/accuracy profile (default: Robust).
public Int32 MaxDimension { get; set; } #Maximum dimension (pixels) for decoding. Larger inputs will be downscaled by sampling. Set to 0 to disable.
public Int32 MaxScale { get; set; } #Maximum scale to try when decoding (1..8). Set to 0 to use profile defaults.
public Int32 MaxMilliseconds { get; set; } #Maximum milliseconds to spend decoding (best effort). Set to 0 to disable.
public Int32 BudgetMilliseconds { get; set; } #Hard budget in milliseconds for decoding (best effort), without profile downgrades. When set, this is used for internal time budgeting instead of MaxMilliseconds.
public Boolean AutoCrop { get; set; } #Attempts to auto-crop likely QR regions before decoding (useful for screenshots).
public Boolean EnableTileScan { get; set; } #Enables tile-based scanning for multiple QR codes in one image.
public Int32 TileGrid { get; set; } #Tile grid size for multi-scan (0 = auto, 2..4 recommended).
public Boolean DisableTransforms { get; set; } #Disable rotation/mirroring attempts even in robust profiles.
public Boolean AggressiveSampling { get; set; } #Enables extra thresholding/sampling passes for stylized or noisy QR codes (slower).
public Boolean StylizedSampling { get; set; } #Enables stylized sampling tuned for QR art (opt-in, slower).
