FORMIT_CORE_EXPORT ::string FormIt::Utils::CreateTextureFileFromData	(	const 1::vector< char > &	data,
		const 1::string &	fileName,
		bool	bForceRemake = false
	)

Create the texture cache file from a texture's bit data.

It is assumed that the data is in png or jpg format

Parameters

[in]	data
[in]	fileName
[in]	bForceRemake

FORMIT_CORE_EXPORT ::shared_ptr<FormIt::Utils::UtilsImage> FormIt::Utils::DecodeImage	(	unsigned char *	data,
		int	size,
		bool	swapredblue = false,
		bool	flip = false
	)

Create an Image object from input image data (JPEG or PNG format)

Parameters

[out]	data
[in]	size
[in]	swapredblue
[in]	flip

FORMIT_CORE_EXPORT ::vector<char> FormIt::Utils::EncodeImageJPG	(	unsigned char *	imageData,
		size_t	image_width,
		size_t	image_height,
		size_t	bytesPerPixel,
		bool	encodeAlphaOnly,
		int	quality = 80
	)

Create JPG formatted data from raw rgb (bytesPerPixel == 3) or rgba (bytesPerPixel == 4) pixel data.

jpg quality 0 ... 100

Parameters

imageData	Vector of R,G,B or R,G,B-A order data
image_width	Number of columns in image
image_height	Number of rows in image
bytesPerPixel	should be 3 (RGB) or 4 (RGBA)
encodeAlphaOnly	if true, the alpha channel of the input will be used to create a grayscale jpg
quality	assuming there is an alpha channel. Otherwise the RGB channels will be used

FORMIT_CORE_EXPORT ::vector<unsigned char> FormIt::Utils::EncodeImagePNG	(	1::vector< unsigned char > &	imgData,
		size_t	width,
		size_t	height,
		size_t	bytesPerPixel
	)

Create PNG formatted data from raw rgb (bytesPerPixel == 3) or rgba (bytesPerPixel == 4) pixel data.

Parameters

[out]	imgData
[in]	width
[in]	height
[in]	bytesPerPixel
