Functions
rgb *	create_rgb (int width, int height)
rgba *	create_rgba (int width, int height)
	Make a system-memory 32-bit bitmap surface. Packed data, red byte first.
alpha *	create_alpha (int width, int height)
	Make a system-memory 8-bit bitmap surface.
void	write_jpeg (tu_file *out, rgb *image, int quality)
	Write the given image to the given out stream, in jpeg format.
rgb *	read_jpeg (const char *filename)
	Create and read a new image from the given filename, if possible.
rgb *	read_jpeg (tu_file *in)
	Create and read a new image from the stream.
rgb *	read_swf_jpeg2_with_tables (jpeg::input *loader)
	For reading SWF JPEG2-style image data, using pre-loaded headers stored in the given jpeg::input object.
rgba *	read_swf_jpeg3 (tu_file *in)
	For reading SWF JPEG3-style image data, like ordinary JPEG, but stores the data in rgba format.
void	write_tga (tu_file *out, rgba *image)
	Write a 32-bit Targa format bitmap. Dead simple, no compression.
DSOEXPORT void	resample (rgb *out, int out_x0, int out_y0, int out_x1, int out_y1, rgb *in, float in_x0, float in_y0, float in_x1, float in_y1)

Function Documentation

DSOEXPORT alpha * image::create_alpha	(	int	width,
		int	height
	)

Make a system-memory 8-bit bitmap surface.

DSOEXPORT rgb * image::create_rgb	(	int	width,
		int	height
	)

Make a system-memory 24-bit bitmap surface. 24-bit packed data, red byte first.

DSOEXPORT rgba * image::create_rgba	(	int	width,
		int	height
	)

Make a system-memory 32-bit bitmap surface. Packed data, red byte first.

DSOEXPORT rgb * image::read_jpeg

(

tu_file *

in

)

Create and read a new image from the stream.

Parameters:

in

Stream to read from. Ownership to the caller, not needed after return.

DSOEXPORT rgb * image::read_jpeg

(

const char *

filename

)

Create and read a new image from the given filename, if possible.

DSOEXPORT rgb* image::read_swf_jpeg2

(

tu_file *

in

)

For reading SWF JPEG2-style image data (slight variation on ordinary JPEG).

DSOEXPORT rgb * image::read_swf_jpeg2_with_tables

(

jpeg::input *

j_in

)

For reading SWF JPEG2-style image data, using pre-loaded headers stored in the given jpeg::input object.

DSOEXPORT rgba * image::read_swf_jpeg3

(

tu_file *

in

)

For reading SWF JPEG3-style image data, like ordinary JPEG, but stores the data in rgba format.

void image::resample	(	image::rgba *	out,
		int	out_x0,
		int	out_y0,
		int	out_x1,
		int	out_y1,
		image::rgba *	in,
		float	in_x0,
		float	in_y0,
		float	in_x1,
		float	in_y1
	)

void image::resample	(	image::rgb *	out,
		int	out_x0,
		int	out_y0,
		int	out_x1,
		int	out_y1,
		image::rgb *	in,
		float	in_x0,
		float	in_y0,
		float	in_x1,
		float	in_y1
	)

DSOEXPORT void image::write_jpeg	(	tu_file *	out,
		rgb *	image,
		int	quality
	)

Write the given image to the given out stream, in jpeg format.

DSOEXPORT void image::write_tga	(	tu_file *	out,
		rgba *	im
	)

Write a 32-bit Targa format bitmap. Dead simple, no compression.
