Function Documentation

Ppm_WriteRgbImage()

int Ppm_WriteRgbImage	(	const char *	path,
		const RgbaColor *	pixels,
		int	width,
		int	height
	)

Exports an RGBA buffer to standard PPM format.

Parameters

path	File path destination.
pixels	Source RGBA pixels.
width	Image width.
height	Image height.

Returns

0 on success; negative value on file open error.

Ppm_WriteRgbImageScaled()

int Ppm_WriteRgbImageScaled	(	const char *	path,
		const RgbaColor *	pixels,
		int	width,
		int	height,
		int	scale
	)

Exports an RGBA buffer scaled by an integer factor to standard PPM.

Parameters

path	File path destination.
pixels	Source RGBA pixels.
width	Canvas width before scaling.
height	Canvas height before scaling.
scale	Integer scaling multiplier.

Returns

0 on success; negative value on file open error.
