| Constant | Value | Description |
| IMAGE_REL_BASED_ABSOLUTE | 0 | The fixup is skipped. This type can be used to pad a block. |
| IMAGE_REL_BASED_HIGH | 1 | The fixup adds the high 16 bits of the delta to the 16-bit field at Offset. The 16-bit field represents the high value of a 32-bit word. |
| IMAGE_REL_BASED_LOW | 2 | The fixup adds the low 16 bits of the delta to the 16-bit field at Offset. The 16-bit field represents the low half of a 32-bit word. This fixup is emitted for a RISC machine only when the image Object Align value is not the default of 64K. |
| IMAGE_REL_BASED_HIGHLOW | 3 | The fixup applies the 32-bit delta to the 32-bit field at Offset. The high 16 bits are located at Offset, and the low 16 bits are located in the next Offset record. The two need to be combined into a signed variable. |
| IMAGE_REL_BASED_HIGHADJ | 4 | This fixup requires a full 32-bit value. |
| IMAGE_REL_BASED_MIPS_JMPADDR | 5 | Fixup applies to a MIPS jump instruction. |
