Description |
|
|
uStructSize |
Size of this structure, in bytes. Use the sizeof operator to calculate this value. |
|
|
pBitmap |
Ignored. |
|
|
bZoomToFit |
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)". |
|
uLow |
Lowest intensity to detect. Possible values range from 0 – 255. |
|
uHigh |
Highest intensity to detect. Possible values range from 0 – 255. |
|
uChannel |
A value that indicates the channel to process. Possible values are: |
|
|
Value |
|
|
IDB_CHANNEL_MASTER |
|
|
IDB_CHANNEL_RED |
|
|
IDB_CHANNEL_GREEN |
|
|
IDB_CHANNEL_BLUE |
|
crInColor |
The color used to fill those pixels having an intensity value between uLow and uHigh. This parameter has no effect if the uChannel parameter is set to IDB_CHANNEL_MASTER. If for example the uChannel parameter is set to IDB_CHANNEL_RED, then the red component of crInColor will be used to fill the pixels having a red component value between uLow and uHigh. |
|
crOutColor |
The color used to fill those pixels having an intensity value less than uLow or greater than uHigh. This parameter has no effect if the uChannel parameter is IDB_CHANNEL_MASTER. If for example the uChannel parameter is set to IDB_CHANNEL_RED, then the red component of crOutColor will be used to fill the pixels having a red component value less than uLow or greater than uHigh. |
|
uDlgFlags |
User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are: |
|
|
|
Value |
Meaning |
|
|
DLG_INTENSITYDETECT_SHOW_CONTEXTHELP |
0x00000002] dialog should contain a context sensitive help icon. |
|
pfnHelpCallback |
Ignored. |
|
|
pHelpCallBackUserData |
Ignored. |
