Description

Methods

Protected function IsEmpty: Boolean;

This item has no description. Showing description inherited from ICefImage.IsEmpty.

Returns true (1) if this Image is NULL.

Protected function IsSame(const that: ICefImage): Boolean;

This item has no description. Showing description inherited from ICefImage.IsSame.

Returns true (1) if this Image and |that| Image share the same underlying storage. Will also return true (1) if both images are NULL.

Protected function AddBitmap(scaleFactor: Single; pixelWidth, pixelHeight: Integer; colorType: TCefColorType; alphaType: TCefAlphaType; const pixelData: Pointer; pixelDataSize: NativeUInt): Boolean;

This item has no description. Showing description inherited from ICefImage.AddBitmap.

Add a bitmap image representation for |scale_factor|. Only 32-bit RGBA/BGRA formats are supported. |pixel_width| and |pixel_height| are the bitmap representation size in pixel coordinates. |pixel_data| is the array of pixel data and should be |pixel_width| x |pixel_height| x 4 bytes in size. |color_type| and |alpha_type| values specify the pixel format.

Protected function AddPng(scaleFactor: Single; const pngData: Pointer; pngDataSize: NativeUInt): Boolean;

This item has no description. Showing description inherited from ICefImage.AddPng.

Add a PNG image representation for |scale_factor|. |png_data| is the image data of size |png_data_size|. Any alpha transparency in the PNG data will be maintained.

Protected function AddJpeg(scaleFactor: Single; const jpegData: Pointer; jpegDataSize: NativeUInt): Boolean;

This item has no description. Showing description inherited from ICefImage.AddJpeg.

Create a JPEG image representation for |scale_factor|. |jpeg_data| is the image data of size |jpeg_data_size|. The JPEG format does not support transparency so the alpha byte will be set to 0xFF for all pixels.

Protected function GetWidth: NativeUInt;

This item has no description. Showing description inherited from ICefImage.GetWidth.

Returns the image width in density independent pixel (DIP) units.

Protected function GetHeight: NativeUInt;

This item has no description. Showing description inherited from ICefImage.GetHeight.

Returns the image height in density independent pixel (DIP) units.

Protected function HasRepresentation(scaleFactor: Single): Boolean;

This item has no description. Showing description inherited from ICefImage.HasRepresentation.

Returns true (1) if this image contains a representation for |scale_factor|.

Protected function RemoveRepresentation(scaleFactor: Single): Boolean;

This item has no description. Showing description inherited from ICefImage.RemoveRepresentation.

Removes the representation for |scale_factor|. Returns true (1) on success.

Protected function GetRepresentationInfo(scaleFactor: Single; var actualScaleFactor: Single; var pixelWidth, pixelHeight: Integer): Boolean;

This item has no description. Showing description inherited from ICefImage.GetRepresentationInfo.

Returns information for the representation that most closely matches |scale_factor|. |actual_scale_factor| is the actual scale factor for the representation. |pixel_width| and |pixel_height| are the representation size in pixel coordinates. Returns true (1) on success.

Protected function GetAsBitmap(scaleFactor: Single; colorType: TCefColorType; alphaType: TCefAlphaType; var pixelWidth, pixelHeight: Integer): ICefBinaryValue;

This item has no description. Showing description inherited from ICefImage.GetAsBitmap.

Returns the bitmap representation that most closely matches |scale_factor|. Only 32-bit RGBA/BGRA formats are supported. |color_type| and |alpha_type| values specify the desired output pixel format. |pixel_width| and |pixel_height| are the output representation size in pixel coordinates. Returns a ICefBinaryValue containing the pixel data on success or NULL on failure.

Protected function GetAsPng(scaleFactor: Single; withTransparency: Boolean; var pixelWidth, pixelHeight: Integer): ICefBinaryValue;

This item has no description. Showing description inherited from ICefImage.GetAsPng.

Returns the PNG representation that most closely matches |scale_factor|. If |with_transparency| is true (1) any alpha transparency in the image will be represented in the resulting PNG data. |pixel_width| and |pixel_height| are the output representation size in pixel coordinates. Returns a ICefBinaryValue containing the PNG image data on success or NULL on failure.

Protected function GetAsJpeg(scaleFactor: Single; quality: Integer; var pixelWidth, pixelHeight: Integer): ICefBinaryValue;

This item has no description. Showing description inherited from ICefImage.GetAsJpeg.

Returns the JPEG representation that most closely matches |scale_factor|. |quality| determines the compression level with 0 == lowest and 100 == highest. The JPEG format does not support alpha transparency and the alpha channel, if any, will be discarded. |pixel_width| and |pixel_height| are the output representation size in pixel coordinates. Returns a ICefBinaryValue containing the JPEG image data on success or NULL on failure.

Public class function UnWrap(data: Pointer): ICefImage;
