| 519 | //* Purpose : Creates a cursor based on the DIB info. returned by ReadCursor.* |
| 520 | //* Parameters : HANDLE hDIB - A handle to the cursor's DIB information. * |
| 521 | //* LPPOINT lppt - A pointer to a point struct. indicating the * |
| 522 | //* location of the Cursor's hot spot. * |
| 523 | //* Returns : A handle to a cursor. NULL is returned if a cursor cannot be * |
| 524 | //* successfully created. * |
| 525 | //* Comments : The steps involved in making a cursor from a DIB are very * |
| 526 | //* similar to those involved in making an icon from a DIB. * |
| 527 | //* Steps : 1) Obtain a pointer to the Cursor's DIB bits. * |
| 528 | //* 2) Divide the DIB's height with 2 to account for the fact that the* |
| 529 | //* DIB stores both the XOR and the AND masks, one after the other.* |
| 530 | //* 3) Determine the offset to the XOR bits. * |
| 531 | //* 4) Determine the offset to the AND bits. * |
| 532 | //* 5) Create a device dependent bitmap with the XOR bits. * |
| 533 | //* 6) Obtain the device dependent XOR bitmask and save in memory. * |
| 534 | //* The AND bitmask is monochrome. Monochrome bits are identical * |
| 535 | //* in both the device dependent bitmaps and device independent * |
| 536 | //* bitmaps. So, no need to convert the AND bitmask. * |
| 537 | //* 7) Since a DIB is stored upside down, flip the monochrome AND bits* |
| 538 | //* by scanlines. * |
| 539 | //* 8) Use the XOR and AND bits and create a cursor with CreateCursor.* |
