This function creates a new empty image that does not have pixel data allocated.

Declaration:

	Copy Code
AT_ERRCOUNT ACCUAPI IG_image_create_empty( HIGDIBINFO hDIB, HIGEAR* lphIGear );

Arguments:

Name	Type	Description
hDIB	HIGDIBINFO	DIB info object with parameters used to create image.
lphIGear	HIGEAR*	Returned HIGEAR handle of created image.

Return Value:

Returns 0 if successful. Otherwise, returns the number of ImageGear errors that occurred during this function call.

Supported Raster Image Formats:

All pixel formats supported by ImageGear for C and C++.

Example:

// Create a new image with the same parameters as an existing image, // but with no pixel data allocated AT_ERRCOUNT nErrcount; // Number of errors on stack HIGEAR hIGear; // Handle of image HIGDIBINFO hDIB; // DIB info handle of image HIGEAR hIGearCreated; // Handle of created image // Load image file "picture.bmp" from working directory nErrcount = IG_load_file("picture.bmp", &hIGear); if(nErrcount == 0) { // Get DIB info of the existion image // DIB info can be also created and filled in manually nErrcount = IG_image_DIB_info_get(hIGear, &hDIB); if(nErrcount == 0) { nErrcount = IG_image_create_empty(hDIB, &hIGearCreated); // Destroy DIB info IG_DIB_info_delete(hDIB); // ... // Destroy the image IG_image_delete(hIGearCreated); } // Destroy the source image IG_image_delete(hIGear); }
