Image graphics object is a kind of PDF graphics object, so class FSImageObject is derived from class FSGraphicsObject . It offers functions to get/set image graphics object's data.
To create a new image graphics object, please use function FSImageObject::create: and then use setting functions to set information to the new image graphics object.
- (FSBitmap *) cloneBitmap: | (FSGraphicsObjects*) | graphics_objects |
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:
FSBitmapDIB8bppMask, FSBitmapDIB8bpp, FSBitmapDIBRgb, FSBitmapDIBRgb32, FSBitmapDIBArgb.
If the return value of function FSBitmap::isEmpty for the returned bitmap object is YES, that means the DIB format of the bitmap is unsupported.
[in] | graphics_objects | A valid FSGraphicsObjects object. Please ensure that current image graphics object just belongs to this FSGraphicsObjects object (it may be a PDF page). |
+ (FSImageObject *) create: | (FSPDFDoc*) | document |
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. |
- (FSColorSpaceType) getColorSpace |
Get color space.
- (FSPDFObject *) getMask |
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:
Please refer to Section 4.8.4 "Image Dictionaries" in <PDF Reference 1.7> for more details.
- (FSPDFStream *) getStream |
Get image stream.
- (BOOL) isImageMask |
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 FSBitmapDIB8bppMask. This is useful only when parameter bitmap does not have an alpha channel. |
- (void) setImage: | (FSImage*) | image | |
frame_index: | (int) | frame_index | |
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 FSImageUnknown. |
[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 FSImage::getFrameCount. |
