Member Function Documentation

At() [1/2]

Rgba32 porytiles::CImgPng::At ( std::size_t  i ) const

overridevirtual

Fetches the Rgba32 color value at a given one-dimensional pixel index.

The one-dimensional index assumes the Png as an array of pixels, where the length of the array is the Png's width times height.

Parameters

i	The one-dimensional pixel index.

Returns

The Rgba32 at the given pixel index.

Implements porytiles::Png.

Definition at line 25 of file cimg_png.cpp.

At() [2/2]

Rgba32 porytiles::CImgPng::At ( std::size_t  row, std::size_t  col  ) const

overridevirtual

Fetches the Rgba32 color value at a given row and column.

Parameters

row	The pixel row.
col	The pixel column.

Returns

The Rgba32 at the given row and column.

Implements porytiles::Png.

Definition at line 29 of file cimg_png.cpp.

Height()

std::size_t porytiles::CImgPng::Height ( ) const

overridevirtual

Gets the height of this Png in pixels.

Returns

The height of this Png in pixels.

Implements porytiles::Png.

Definition at line 21 of file cimg_png.cpp.

Width()

std::size_t porytiles::CImgPng::Width ( ) const

overridevirtual

Gets the width of this Png in pixels.

Returns

The width of this Png in pixels.
