ImageGear Professional DLL for Windows
IG_FX_stitch
ImageGear Professional v18.2 > API Reference Guide > Core Component API Reference > Core Component Functions Reference > FX Functions > IG_FX_stitch

This function produces an effect similar to IG_FX_emboss(), except that the output more closely resembles a quilted stitch pattern.

Declaration:

 
Copy Code 
AT_ERRCOUNT ACCUAPI IG_FX_stitch (
        HIGEAR hIGear, 
        const LPAT_RECT lpRect, 
        AT_MODE nCompassDir, 
        const DOUBLE dblStrength,
);

Arguments:

Name Type Description
hIGear HIGEAR HIGEAR handle of image.
lpRect const LPAT_RECT Far pointer to an AT_RECT struct specifying a rectangular portion of the image to be processed. NULL for the whole image. Before ImageGear performs this operation, it will check to see if an internal flag has been set to TRUE to make a mask active for this HIGEAR image. If a mask is active, and a valid pointer to a mask can be found, ImageGear will override the settings passed to this structure in favor of the non-rectangular ROI defined by the mask.
nCompassDir AT_MODE An AT_MODE Compass direction constant. Please see accucnst.h file or the description of IG_FX_emboss() function for full list of these constants.
dblStrength const DOUBLE 0.0 to 5.0 (A very low value will produce a gray screen with no detail.)

Return Value:

Returns the number of ImageGear errors that occurred during this function call.

Supported Raster Image Formats:

All pixel formats supported by ImageGear Professional, except:
Indexed RGB – 1 bpp;
Grayscale – 1 bpp.

Sample:

FlashPix

Example:

 
Copy Code 
HIGEAR hIGear;        /* HIGEAR handle of image */
AT_RECT rcImageRect;  /* Image's current image rectangle */
/* Emboss only the image rect portion: */
IG_FX_stitch ( hIGear, &rcImageRect, IG_COMPASS_NE, 3.0 );

Remarks:

This function, like other ImageGear Image Processing and Clipboard API calls, takes an AT_RECT structure as an argument, so that you can process a rectangular sub-region of an image. (See above.) However, before ImageGear performs the operation specified by this function, it will check to see if an internal flag has been set to TRUE, indicating that a mask HIGEAR should be used with the image. If the flag is set to TRUE, and a valid pointer to a mask image has been assigned, ImageGear will override the settings passed to the AT_RECT structure and use the non-rectangular ROI defined by the mask HIGEAR. To create a non-rectangular region of interest, call IG_IP_NR_ROI_to_HIGEAR_mask().

Please see the descriptions of IG_IP_NR_ROI_mask_associate() and IG_IP_NR_ROI_to_HIGEAR_mask() for more details.
