API Reference Guide > Core Component API Reference > Core Component Functions Reference > Clipboard Functions > IG_clipboard_paste_available_ex

This function tells you whether the clipboard contains a valid image or region of interest (ROI) that can be pasted into an image.

Declaration:

 
Copy Code
AT_ERRCOUNT ACCUAPI IG_clipboard_paste_available_ex (
        LPBOOL lpPasteStatus,
        LPAT_MODE lpRegionType
);

Arguments:

Name Type Description
lpPasteStatus LPBOOL A far pointer that returns TRUE if the clipboard contains a region of interest that can be pasted into an image.
lpRegionType LPAT_MODE A far pointer that returns the type of region stored in the clipboard. Currently the valid values are IG_REGION_IS_RECT, IG_REGION_IS_NON_RECT, IG_REGION_IS_NOT_AVAIL.

Return Value:

Returns the number of ImageGear errors that occurred during this function call. If there are no errors, the return value is IGE_SUCCESS.

Supported Raster Image Formats:

This function does not process image pixels.

Sample:

Image Processing

Example:

 
Copy Code
AT_ERRCOUNT nErrcount;
HIGEAR hIGear;
BOOL bNRpasteAvail; /* TRUE if a pasteable image is on clipboard */
AT_MODE nRegionType; /* type of region on the clipboard */
nErrcount = IG_clipboard_paste_available_ex(&bNRpasteAvail, &nRegionType);
if (bNRpasteAvail)
        (...)

Remarks:

It also returns the type of region contained in the clipboard: rectangular, non-rectangular, or not available. If the clipboard does contain a valid ROI, lpPasteStatus returns TRUE; if lpPasteStatus returns FALSE, the region type returned is IG_REGION_IS_NOT_AVAIL.

A return value of FALSE does not necessarily mean that the clipboard is empty. It could mean that the clipboard contains non-valued ROI data or text, or that it contains multimedia data.

To paste a rectangular or non-rectangular ROI into the current image, call IG_clipboard_paste_merge_ex().
