Detailed Description

Wraps a set of rows from a image, read in a single operation, stored in a int[][] or byte[][] matrix

They can be a subset of the total rows, but in this case they are equispaced.

int Hjg.Pngcs.ImageLines.ImageRowToMatrixRow

(

int

imrow

)

Translates from image row number to matrix row. If you are not sure if this image row in included, use better ImageRowToMatrixRowStrict

Parameters

imrow

Row number in the original image (from 0)

Returns

Row number in the wrapped matrix. Undefined result if invalid

int Hjg.Pngcs.ImageLines.ImageRowToMatrixRowStrict

(

int

imrow

)

translates from image row number to matrix row

Parameters

imrow

Row number in the original image (from 0)

Returns

Row number in the wrapped matrix. Returns -1 if invalid

int Hjg.Pngcs.ImageLines.MatrixRowToImageRow

(

int

mrow

)

Translates from matrix row number to real image row number

Parameters

mrow

Returns

ImageLine Hjg.Pngcs.ImageLines.GetImageLineAtMatrixRow

(

int

mrow

)

Constructs and returns an ImageLine object backed by a matrix row. This is quite efficient, no deep copy.

Parameters

mrow	Row number inside the matrix

Returns
