Description |
|
|
uStructSize |
Specifies the structure size. It should be equal to sizeof(OMROPTIONS). |
|
|
bFill |
Flag that indicates whether the recognition output can take two or three values. Possible values are: |
|
|
|
Value |
Meaning |
|
|
TRUE |
Three values are possible for grouped zones: |
|
|
|
0 = unfilled, |
|
|
|
1 = filled, |
|
|
|
2 = filled-in-error. |
|
|
FALSE |
Only one of two values can be generated for each RM_OMR zone: |
|
|
|
0 = unfilled |
|
|
|
1 = filled |
|
Frame |
Frame detection method to be set. This specifies whether the OMR zone borders will be visible or invisible in the images. For a list of possible values, refer to OMRFRAME. |
|
|
Sense |
Mark sensitivity level to be set (Default: OMR_SENSE_NORMAL). For a list of possible values, refer to OMRSENSE. |
|
Comments
The default values are:
|
|
* |
two-value output from recognition, |
|
|
* |
OMR_FRAME_AUTO detection mode, |
|
|
* |
OMR_SENSE_NORMAL sensitivity setting. |
This structure used only when the recognition module is RECOGMODULE_OMR.
pOMROPTIONS is a pointer to a OMROPTIONS structure. Where the function parameter type is pOMROPTIONS, declare a OMROPTIONS variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pOMROPTIONS variable is necessary only if the program requires a pointer.
This structure is used with the following functions:
