Cef |
The CefImage type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | 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. |
| 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. |
| 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. |
 | CreateImage | Create a new CefImage. It will initially be empty. Use the Add*() methods to add representations at different scale factors. |
| Dispose | |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
 | Finalize | (Overrides ObjectFinalize) |
| 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 CefBinaryValue containing the pixel data on success or NULL on failure. |
| 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 CefBinaryValue containing the JPEG image data on success or NULL on failure. |
| GetAsPng | Returns the PNG representation that most closely matches |scale_factor|. If |with_transparency| is true 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 CefBinaryValue containing the PNG image data on success or NULL on failure. |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| 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 on success. |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| HasRepresentation | Returns true if this image contains a representation for |scale_factor|. |
| IsSame | Returns true if this Image and |that| Image share the same underlying storage. Will also return true if both images are empty. |
| RemoveRepresentation | Removes the representation for |scale_factor|. Returns true on success. |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
