NFX_CONVERT_PARMS

The NFX_CONVERT_PARMS structure specifies attributes which are used by nfxConvertFileDirect.

encoding

Default Value

NFX_ENCODE_1D

Allowed Values

NFX_ENCODE_1D or NFX_ENCODE_2D

Description

This parameter specifies the encoding of the data to be stored in the output file. The input file data may be in either NFX_ENCODE_1D or NFX_ENCODE_2D encoding. Note that the encoding affects the size of image data only; it does not affect the appearance of the image.

pagewidth

Default Value

NFX_PAGE_WIDTH_A4

Allowed Values

NFX_PAGE_WIDTH_A4, NFX_PAGE_WIDTH_B4, or NFX_PAGE_WIDTH_A3

Description

This parameter specifies the page width of the data to be stored in the output file. The input file data may have any of the allowed page widths. Note that the number of picture elements (pels) per line is 1728, 2048, and 2432 for NFX_PAGE_WIDTH_A4, NFX_PAGE_WIDTH_B4 and NFX_PAGE_WIDTH_A3, respectively. All are packed with the resolution of 200 picture elements per inch. Converting to a narrower page results in shrinking each line. Converting to a wider page results in padding the right side of the page with blank space.

resolution

Default Value

NFX_RESOLUTION_LOW

Allowed Values

NFX_RESOLUTION_LOW, NFX_RESOLUTION_HIGH, or NFX_RESOLUTION_SUPER_HIGH

Description

This parameter specifies the vertical resolution of the data to be stored in the output file. The input file data may have any of the allowed resolutions. The resolution is 3.85, 7.7, and 15.4 scan lines per millimeter for NFX_RESOLUTION_LOW, NFX_RESOLUTION_HIGH, and NFX_RESOLUTION_SUPER_HIGH, respectively. Note that the horizontal resolution of the data is the same for NFX_RESOLUTION_LOW, NFX_RESOLUTION_HIGH, and NFX_RESOLUTION_SUPER_HIGH. The image appearance will be affected by a change in resolution.

type

Default Value

NFX_TIFF_F

Allowed Values

NFX_TIFF_F

Description

This parameter specifies the overall format of the input file. The only format supported in this release is TIFF-F.

badlineaction

Default Value

NFX_BAD_LINE_ACTION_REPT

Allowed Values

NFX_BAD_LINE_ACTION_REPT, NFX_BAD_LINE_ACTION_DROP, or NFX_BAD_LINE_ACTION_TICK

Description

This parameter specifies how bad lines that are discovered in the input file are to appear in the output file. The default, NFX_BAD_LINE_ACTION_REPT, is to repeat the picture elements of the nearest previous good line. For NFX_BAD_LINE_ACTION_DROP, the bad line is eliminated from the destination file. For NFX_BAD_LINE_ACTION_TICK, the bad line is replaced by a blank line with a short black mark at either end.

When the source file has 2D encoding, an error in a single line may cause up to three subsequent lines to be considered bad as well.
