Image graphics object is a kind of PDF graphics object, so class ImageObject is derived from class GraphicsObject . It offers functions to get/set image graphics object's data.
To create a new image graphics object, please use function ImageObject.Create and then use setting functions to set information to the new image graphics object.

Clone the bitmap from current image graphics object.
Currently, the bitmap can be cloned from image graphics object only when the bitmap format is one of following formats:
foxit.common.Bitmap.DIBFormat.e_DIB8bppMask , foxit.common.Bitmap.DIBFormat.e_DIB8bpp , foxit.common.Bitmap.DIBFormat.e_DIBRgb , foxit.common.Bitmap.DIBFormat.e_DIBRgb32 , foxit.common.Bitmap.DIBFormat.e_DIBArgb .
If the return value of function common.Bitmap.IsEmpty for the returned bitmap object is true, that means the DIB format of the bitmap is unsupported.
[in] | graphics_objects | A valid foxit.pdf.GraphicsObjects object. Please ensure that current image graphics object just belongs to this foxit.pdf.GraphicsObjects object (it may be a PDF page). |
|
inlinestatic |
Create a new image graphics object.
The newly created image graphics object does not have any data yet. Then, setting functions can be called to set data to the new image graphics object.
[in] | document | A valid PDF document object. The new image graphics object should be inserted to one page of this PDF document then. |
|
inline |
Get color space.
|
inline |
Get the PDF object that represents the mask of current image graphics object.
The mask can be either a PDF dictionary or a PDF array:
A PDF dictionary represents an image mask to be applied to this image.
A PDF array represents a range of colors to be applied to it as a color key mask.
Please refer to Section 4.8.4 "Image Dictionaries" in <PDF Reference 1.7> for more details.

Get image stream.
|
inline |
Check if current image object is treated as mask.
Set a bitmap to current image graphics object.
[in] | bitmap | A valid bitmap object to be set to current image. |
[in] | mask | Mask bitmap. If this is valid, its format should be foxit.common.Bitmap.DIBFormat.e_DIB8bppMask . This is useful only when parameter bitmap does not have an alpha channel. |
|
inline |
Set one frame of an image to current image graphics object.
Input image may contain multiple frames, and only one frame of the image can be set to current image graphics object.
[in] | image | A valid image object. This image should contain at least one frame and the image type should not be foxit.common.Image.Type.e_Unknown . |
[in] | frame_index | Frame index used to decide which frame of parameter image is to be set. Valid range: from 0 to (count-1). count is returned by function common.Image.GetFrameCount . |
