The ANTIALIASDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogImageEffect::DoModalAntiAlias function. After the user closes the dialog box, this structure is updated with information about the user's selections.
Size of this structure, in bytes. Use the sizeof operator to calculate this value.
Ignored.
Flag that indicates the initial zoom level for previewing the image. Possible values are:
Value | Meaning |
---|---|
TRUE | Set the initial zoom level to "Zoom to fit". |
FALSE | Set the initial zoom level to "Normal (1:1)". |
Threshold value that indicates which pixels to smooth. The application of the anti-aliasing filter on the image associates a value with each pixel. Only pixels with values above this threshold are smoothed. Range of possible values are:
If the image is: | Unsigned | Signed |
---|---|---|
12-bit. | 0-4095 | -2048 to +2047 |
16-bit, 48-bit, or 64-bit. | 0-65535 | -32768 to +32767 |
Other bits per pixel. | 0-255 |
Value that indicates the size of the anti-aliasing mask. This value represents the side of a square neighborhood. Possible values range from 2 - 100.
Flag that indicates the type of anti-aliasing filter to use. Possible values are:
Value | Meaning |
---|---|
ANTIALIAS_1 | [0x0000] Anti-alias the bitmap vertically and horizontally. |
ANTIALIAS_2 | [0x0001] Anti-alias the bitmap in all directions. |
ANTIALIAS_3 | [0x0002] Anti-alias the bitmap in all directions. The filter used for this option is different from the filter used for the ANTIALIAS_2 option. |
ANTIALIAS_DIAG | [0x0003] Anti-alias the bitmap diagonally. |
ANTIALIAS_HORZ | [0x0004] Anti-alias the bitmap horizontally. |
ANTIALIAS_VERT | [0x0005] Anti-alias the bitmap vertically. |
User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
Value | Meaning |
---|---|
DLG_ANTIALIAS_SHOW_CONTEXTHELP | [0x00000002] dialog should contain a context sensitive help icon. |
DLG_ANTIALIAS_SHOW_APPLY | [0x00000080] Show the Apply button in the dialog. The dialog will not apply any effect unless the user presses the Apply button. |
