Class ReportShapeHatch

Namespace: DocWright.Reporting.Pagination

Assembly: DocWright.Reporting.dll

A hatch a ReportShapePath or a ReportShapeRegion is filled with (Phase 96): an 8 × 8 tile of cells, each a blend of the Line colour over the Ground by its coverage, repeated across the shape from the owning item's top-left corner on a grid of CellsPerInch cells to the inch.

Remarks

The reference's chart, gauge and map engines draw an item into a 300-dpi bitmap of its own and fill a hatched part with a GDI+ hatch brush, which tiles from that bitmap's corner a cell to a pixel (oracle facts from 213). So the grid is the item's, not the page's: two hatched parts of one item line up, and a part's tile does not start at its own edge. Under the engines' antialiasing three of GDI+'s 53 styles — the plain diagonals and their cross — are three cells wide with partial coverage at their sides, which is why a cell has a coverage and not a bit.

Cell (column, row) of a pixel at (x, y) cells from the item's corner is (x mod 8, y mod 8), and Coverage lists the 64 cells row by row from the top-left. A cell's colour is the line's over the ground's at its coverage: an opaque line on a translucent ground — a semi-transparent palette's — stays opaque.

Constructors

Fields

CellsPerInch: The grid a hatch is drawn on: the reference's item rasters are 300 dpi, a cell to a pixel.

Properties
