User manual

The start position is the point in the file from which the specified binary pattern will
be searched for. The position of the first byte in the file, i.e. the beginning of the file,
is offset 1. The second byte then has an offset of 2, etc. The end position is the
offset up to which the pattern is searched for.
If the number in one or both of these fields is prefixed with a minus sign (“-”), the
bytes are counted in reverse. The entry -1, for example, is the last byte of the file. -2
would then be the last but one byte, etc. The file size is irrelevant for this purpose. A
start position of 1 and an end position of -1 means that the entire file will be
searched for the specified pattern. You can also enter two negative values for
example -6 as start position and -1 as end position. The search is then performed
from the last byte to the sixth from last byte, regardless of the byte size of the file.
A positive start position and a negative end position are always possible, for
example 11 as start position (the eleventh byte) and -10 as end position (the tenth
byte from the end). You can not enter a negative start position and a positive end
position.

When you open the pattern settings for a bitmap file, the following dialog appears:
