API Reference Guide > Recognition Component API Reference > Recognition Component Functions Reference > Converter Settings Functions > IG_REC_converter_pagemargins_set

Sets left, top, right, and bottom margins of the output page, in TWIPS (1/1400 inch).

Declaration:

 
Copy Code
AT_ERRCOUNT ACCUAPI IG_REC_converter_pagemargins_set(
   LPCSTR lpszFormatName,
   AT_INT nLeft,
   AT_INT nTop,
   AT_INT nRight,
   AT_INT nBottom
);

Arguments:

Name Type Description
lpszFormatName LPCSTR Symbolic name of the output format like Converters.Text.Cvs.
nLeft AT_INT Left margin to be set.
nTop AT_INT Top margin to be set.
nRight AT_INT Right margin to be set.
nBottom AT_INT Bottom margin to be set.

Return Value:

The number of ImageGear errors that occurred during the function call.

Supported Raster Image Formats:

This function does not process image pixels.

Example:

 
Copy Code
AT_ERRCOUNT ErrCount = 0;
AT_BOOL bCPMIsApplicable = FALSE;
LPCSTR lpszFormatName = "Converters.Text.Csv";
AT_INT iMLeft = 0;
AT_INT iMTop = 0;
AT_INT iMRight = 100;
AT_INT iMBottom = 200;

ErrCount += IG_REC_output_format_set(lpszFormatName);
ErrCount += IG_REC_converter_pagemargins_is_applicable(lpszFormatName,
    &bCPMIsApplicable);
if(bCPMIsApplicable)
    ErrCount += IG_REC_converter_pagemargins_set(lpszFormatName,
    iMLeft, iMTop, iMRight, iMBottom);
ErrCount += IG_REC_converter_pagemargins_usage_set(lpszFormatName, TRUE);

Remarks:

See IG_REC_converter_pagemargins_usage_set for formats that support this setting. Use IG_REC_converter_pagemargins_is_applicable to know whether the specified format supports margins.

Margins can't be set if the corresponding output format has not been selected with IG_REC_output_format_set at least once. In this case the function returns a non-zero value and appends IGE_REC_CONVERTER_NOT_INITIALIZED error code to the error stack.
