Meziantou.FrameworkPnmPixelLayout Enum
The pixel layout written by PnmEncoder.
public enum PnmPixelLayoutFields
| Name | Value | Description |
|---|---|---|
Auto | 0 | The variant follows the pixel format: a portable graymap for gray pixel formats, a portable pixmap for pixel formats without alpha and a portable arbitrary map for pixel formats with alpha. This is the default: no sample and no alpha value is ever discarded. |
Bitmap | 1 | A portable bitmap, one bit per pixel (P4, or P1 with PnmEncoding.Plain). Every pixel must be exactly black or exactly white, whatever the pixel format: any other pixel is rejected with an UnsupportedImageFeatureException, because the encoder never thresholds nor dithers. Alpha is discarded, so a pixel format with alpha requires PnmEncoder.BackgroundColor unless every pixel is opaque. |
