ImageConverter Class

Перечисления (Enums)

MIPMAPS_MODE#

Имя	Описание
DISABLE = 0	Mipmaps are not generated.
POINT = 1	Point filtering method is used at mipmap generation.
LINEAR = 2	Linear filtering method is used at mipmap generation.
BLUR = 3	Blurring is applied at mipmap generation.
SHARPEN = 4	Sharpening is applied at mipmap generation.
COMBINED = 5	Combination of the loaded 2D image with the most detailed mipmap image.
GGX = 6	Generation of mipmaps for cubemap images (IMAGE_CUBE or IMAGE_CUBE_ARRAY) using GGX BRDF microfacet model.

RESOLUTION_MODE#

Имя	Описание
AUTO = 0	Resolution set by the converter depending on the image format (for example, the 2D image is converted to 2D array / 3D image).
ORIGINAL = 1	Resolution of the original image.
MANUAL = 2	Resolution set manually in the converter.

COMPRESSION_QUALITY#

Имя	Описание
LOW = 0	Low quality of compression.
HIGH = 1	High quality of compression.

RESIZE_FILTER#

Имя	Описание
POINT = 0	Point filtering method used for resizing.
LINEAR = 1	Linear filtering method used for resizing.
MIN = 2	Minimum filtering method used for resizing.

RANGE_MODE#

Имя	Описание
DISABLE = 0	Image values are not normalized.
NORMALIZE = 1	Values in all channels of the image are normalized altogeter to the values from 0 to 1 (i.e. overall brightness of the image). Recommended to be used for colors.
NORMALIZE_PER_CHANNEL = 2	Normalization to the values from 0 to 1 is performed for each channel of the image separately.
MANUAL = 3	Normalization to manually set values is performed.

ImageConverter ( ) #

Default constructor. An empty instance with default parameters is created.

ImageConverter ( ImageConverter imageconverter ) #

Constructor. Creates an image converter by copying a given source image converter.

Arguments

• ImageConverter imageconverter - Source image converter.

void SetRange ( int channel, dvec4 value ) #

Sets the range to be applied at the image conversion.

Arguments

• int channel - Number of the channel to be inverted, in the range from 0 to the total number of channels.
• dvec4 value - Range values: x and y coordinates of the value specify the original range, z and w specify the range to which the image will be converted.

dvec4 GetRange ( int channel ) #

Returns the range to be applied at the image conversion.

Arguments

• int channel - Number of the channel to be inverted, in the range from 0 to the total number of channels.

Return value

Range values: x and y coordinates of the value specify the original range, z and w specify the range to which the image will be converted.

bool GetInvertChannel ( int channel ) #

Returns the value indicating if the channel needs to be inverted.

Arguments

• int channel - The number of the channel to be inverted, in the range from 0 to the total number of channels.

Return value

true if the channel needs to be inverted; otherwise, false.

void SetInvertChannel ( int channel, bool value ) #

Inverts the values stored in the specified channel. Channels of images of half (FORMAT_R16F to FORMAT_RGBA16F) and float (FORMAT_R32F to FORMAT_RGBA32F) formats cannot be inverted.

Arguments

• int channel - The number of the channel to be inverted, in the range from 0 to the total number of channels.
• bool value - true if the channel needs to be inverted; otherwise, false.

void Reset ( ) #

Sets the converter to the default values.

void Copy ( ImageConverter converter ) #

Copies data from the specified source converter.

Arguments

• ImageConverter converter - The source converter.

ImageConverter Clone ( ) #

Creates a clone of the specified source converter.

Return value

The converter to be cloned.

bool Load ( string path ) #

Loads the image converter settings on the disk using the specified path.

Arguments

• string path - The path to the file with the image converter settings.

Return value

true if the image converter settings are loaded successfully; otherwise, false.

void Load ( Json json ) #

Loads the .json object with the image converter settings.

Arguments

• Json json - The object with the image converter settings.

bool Save ( string path ) #

Saves image converter settings on the disk to the specified location.

Arguments

• string path - The path to the file to store the image converter settings.

Return value

true if the image converter settings are saved successfully; otherwise, false.

void Save ( Json json ) #

Saves image converter settings to the specified .json object.

Arguments

• Json json - The object with the image converter settings.

void UpdateParameters ( Image image ) #

Validates the parameters of the image converter for the specified image. This method allows checking the resulting parameters before converting the image.

Arguments

• Image image - The image to be converted.

bool RunCpu ( Image image ) #

Runs the image converter on CPU.

Arguments

• Image image - The image to be converted.

Return value

true if the image has been converted successfully; otherwise, false.

bool Run ( Converted on_converted, Image image ) #

Runs the image converter.

Arguments

• Converted on_converted - Callback to be fired after image conversion.
• Image image - Image to be converted.

Return value

true if the image has been converted successfully; otherwise, false.
