Description

Parameters

FontContextOcrId

Specifies the identifier of the OCR font context to modify.

Operation

Specifies the type of operation to perform. This parameter can be set to one or more of the following values:

For specifying the type of operation
Value	Description
M_INVERT	Physically inverts the character representation of the font (for example, if the foreground is white, this will change it to black).
M_RESIZE	Scales the font. This operation physically changes the size of the characters of the font to match the target character size (M_TARGET_CHAR_SIZE_X and M_TARGET_CHAR_SIZE_Y). Once performed, all of the font's specifications, which were set at allocation (MocrAllocFont()), are modified to this new size. Note that changing the size of the font permanently in the OCR font context can save time when compared to resizing the font before each read/verify operation. Increasing the size of the font might be slower because the resize time might be less than the additional processing time required during a read or verify operation to find characters of a larger font. (summarize) Scales the font. (more details...)

OperationFlag

Specifies the interpolation mode for the function. This parameter can be set to one of the following:

For specifying the interpoaltion mode
Value	Description
M_DEFAULT	Same as M_BILINEAR. Note that if the Operation parameter is set to M_INVERT, this parameter should be set to M_DEFAULT. No interpolation is done with M_INVERT. (summarize) Same as M_BILINEAR. (more details...)
M_BICUBIC	Specifies bicubic interpolation. The new value is determined by taking a weighted average of the 16 values (4x4) that surround the source point. Note that the sum of the weights used for bicubic interpolation might be greater than one. If this occurs and the result reflects an overflow or underflow, the result is saturated. (summarize) Specifies bicubic interpolation. (more details...)
M_BILINEAR	Specifies bilinear interpolation. The new value is determined by taking a weighted average of the 4 values (2x2) that surround the source point. (summarize) Specifies bilinear interpolation. (more details...)
M_NEAREST_NEIGHBOR	Specifies nearest neighbor interpolation. The new value is that of the pixel closest to the source point. (summarize) Specifies nearest neighbor interpolation. (more details...)
