Function Documentation

◆ ailiaFormatConvert()

int AILIA_API ailiaFormatConvert	(	void *	dst,
		unsigned int	dst_width,
		unsigned int	dst_height,
		unsigned int	dst_format,
		unsigned int	dst_channel,
		unsigned int	dst_range,
		const void *	src,
		int	src_stride,
		unsigned int	src_width,
		unsigned int	src_height,
		unsigned int	src_format
	)

Converts image formats.

Parameters

dst	The storage location of the image after conversion (numeric type; a size of sizeof(float) dst_width * dst_height * num_of_channel(See Description) or more must be allocated.)
dst_width	The width of the image after conversion
dst_height	The height of the image after conversion
dst_format	The format of the image after conversion (AILIA_NETWORK_IMAGE_FORMAT_*)
dst_channel	The channel order of the image after conversion (AILIA_NETWORK_IMAGE_CHANNEL_*)
dst_range	The range of the image after conversion (AILIA_NETWORK_IMAGE_RANGE_*)
src	The storage location of the source image (32 bpp)
src_stride	The line byte number of the source image
src_width	The width of the source image
src_height	The height of the source image
src_format	The format of the source image (AILIA_IMAGE_FORMAT_*)

Returns: If this function is successful, it returns AILIA_STATUS_SUCCESS , or an error code otherwise.

This function converts image formats. If dst_format is set to AILIA_NETWORK_IMAGE_FORMAT_BGR or AILIA_NETWORK_IMAGE_FORMAT_RGB , the number of channels is 3, otherwise if set to AILIA_NETWORK_IMAGE_FORMAT_GRAY , the number of channels is 1.
