y	int	The pixel y location.
argb_32_color	int	The 32-bit ARGB pixel for the specified position.

Method: set_palette(palette, update_colors)

 set_palette(palette, update_colors) 

Sets the image palette.

Parameters:

Parameter	Type	Description
palette	IColorPalette	The palette to set.
update_colors	bool	if set to true colors will be updated according to the new palette; otherwise color indexes remain unchanged. Note that unchanged indexes may crash the image on loading if some indexes have no corresponding palette entries.

Sets an image pixel for the specified position.

Parameters:

Parameter	Type	Description
x	int	The pixel x location.
y	int	The pixel y location.
color	Color	The pixel color for the specified position.

Method: set_resolution(dpi_x, dpi_y)

 set_resolution(dpi_x, dpi_y) 

Establishes the resolution for the specified RasterImage, ensuring
accurate scaling and printing capabilities. This method empowers users to tailor
the image resolution to suit their specific requirements, whether for digital
display or physical reproduction. By setting the resolution, users can optimize
image quality and ensure compatibility with various output devices and mediums,
enhancing the overall visual experience and usability of the image.

Parameters:

Parameter	Type	Description
dpi_x	double	The horizontal resolution, in dots per inch, of the RasterImage.
dpi_y	double	The vertical resolution, in dots per inch, of the RasterImage.

Method: write_argb_32_scan_line(scan_line_index, argb_32_pixels)

 write_argb_32_scan_line(scan_line_index, argb_32_pixels) 

Writes the whole scan line to the specified scan line index.

Parameters:

Parameter	Type	Description
scan_line_index	int	Zero based index of the scan line.
argb_32_pixels	int	The 32-bit ARGB colors array to write.

Method: write_scan_line(scan_line_index, pixels)

 write_scan_line(scan_line_index, pixels) 

Writes the whole scan line to the specified scan line index.

Parameters:

Parameter	Type	Description
scan_line_index	int	Zero based index of the scan line.
