}

GPUInfo Provides information about the GPU(s) on the system.

type GetInfoReply

type GetInfoReply struct {
	GPU          GPUInfo `json:"gpu"`          // Information about the GPUs on the system.
	ModelName    string  `json:"modelName"`    // A platform-dependent description of the model of the machine. On Mac OS, this is, for example, 'MacBookPro'. Will be the empty string if not supported.
	ModelVersion string  `json:"modelVersion"` // A platform-dependent description of the version of the machine. On Mac OS, this is, for example, '10.1'. Will be the empty string if not supported.
	CommandLine  string  `json:"commandLine"`  // The command line string used to launch the browser. Will be the empty string if not supported.
}

GetInfoReply represents the return values for GetInfo in the SystemInfo domain.

type GetProcessInfoReply

type GetProcessInfoReply struct {
	ProcessInfo []ProcessInfo `json:"processInfo"` // An array of process info blocks.
}

GetProcessInfoReply represents the return values for GetProcessInfo in the SystemInfo domain.

type ImageDecodeAcceleratorCapability

type ImageDecodeAcceleratorCapability struct {
	ImageType     string              `json:"imageType"`     // Image coded, e.g. Jpeg.
	MaxDimensions Size                `json:"maxDimensions"` // Maximum supported dimensions of the image in pixels.
	MinDimensions Size                `json:"minDimensions"` // Minimum supported dimensions of the image in pixels.
	Subsamplings  []SubsamplingFormat `json:"subsamplings"`  // Optional array of supported subsampling formats, e.g. 4:2:0, if known.
}

ImageDecodeAcceleratorCapability Describes a supported image decoding profile with its associated minimum and maximum resolutions and subsampling.

type ProcessInfo

type ProcessInfo struct {

}

ProcessInfo Represents process info.

type Size

type Size struct {
	Width  int `json:"width"`  // Width in pixels.
	Height int `json:"height"` // Height in pixels.
}

Size Describes the width and height dimensions of an entity.
