The invention relates to a method for verifying correct transfer of bitmap data (6 , 6') from a first memory, in particular a main memory (4), to a second memory, in particular a video memory (8), the method comprising: a) modifying at least one property of a number of pixels (12) selected from the bitmap data (6) in the first memory (4), the selection being performed in a random way, b) transferring the bitmap data (6) comprising the modified pixels (12) from the first memory (4) to the second memory (8), c) reading back the modified pixels (12') from the second memory (8), and d) comparing the read-back modified pixels (12') to the modified pixels (12) of the first memory (4) for verifying the correct transfer of the bitmap data (6, 6'). The invention also relates to a computer program product and to a computer system (1, 2) for implementing the method. |
