Contains value that controls the speed, quality, and style of painting operations.
| Value | Member | Description |
|---|---|---|
| 0x00000000 | None | Default |
| 0x00000001 | OrderedDither | Enables or disables ordered dithering when painting. Ordered dithering is faster than the default dithering method, which uses error diffusion, but the quality of the image is not as good. |
| 0x00000002 | FastPaint | Enables or disables fast painting. Fast painting should be performed only if the current video driver is good, and the image does not need to be dithered or resized to paint. No safety check for a faulty driver is performed. |
| 0x00000004 | IndexedPaint | Enables or disables painting that is mapped directly to the selected palette. You can this and let Windows do color matching between the paint palette and the selected palette. Indexed painting uses the colors from the currently selected palette. It is not used if the image is not palletized. |
| 0x00000008 | DitheredPaint | Enables or disables painting that is mapped directly to the selected palette. This is enabled by default; you can set this flag to disable it and let Windows do color matching between the paint palette and the selected palette. Indexed painting uses the colors from the currently selected palette. It is not used if the image is not palletized. |
| 0x00000010 | ScaleToGray | (Document/Medical only) Enables grayscaling of 1-bit images when they are displayed. This improves the readability of the images when they are zoomed in or zoomed out, but it slows down the display. |
| 0x00000020 | HalftonePrint | Enables use of the printing halftone (rather than the viewing halftone) when painting to a 1-bit device. |
| 0x00000040 | FavorBlack | (Document/Medical only) Enables a bias in preserving black objects when displaying zoomed-out 1-bit images. This can prevent the disappearance of fine lines and details, but it slows down the display. |
| 0x00000080 | FixedPalette | Enables the LEAD Fixed palette when displaying 24-bit (or greater) images on 8-bit (or less) devices. |
| 0x00000100 | NetscapePalette | Enables the Netscape Fixed palette when displaying 24-bit (or greater) images on 8-bit (or less) devices. |
| 0x00000200 | Resample | Enables resample resize when displaying images at zoom factors other than 1:1. |
| 0x00000400 | Bicubic | Enables bicubic resize when displaying images at zoom factors other than 1:1. |
