CefImage Methods |
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.) |
