- In case you're interested, the two different transformation matrices that erroneously result in the same key in tx_key are:
-
- (class ivTransformer) =
- {
- unsigned int ivResource::refcount_ = 0x1;
- osboolean identity_ = 0x0;
- float mat00 = 4.096000e-01;
- float mat01 = 0.000000e+00;
- float mat10 = 0.000000e+00;
- float mat11 = 4.096000e-01;
- float mat20 = 1.359938e+02;
- float mat21 = 3.403380e+01;
- }
- x = 1152.960
- y = 1152.960
-
- and
-
- (class ivTransformer) =
- {
- unsigned int ivResource::refcount_ = 0x1;
- osboolean identity_ = 0x0;
- float mat00 = 3.276800e-01;
- float mat01 = 0.000000e+00;
- float mat10 = 0.000000e+00;
- float mat11 = 3.276800e-01;
- float mat20 = 1.832190e+02;
- float mat21 = 8.125903e+01;
- }
- x = 1152.960
- y = 1152.960
-
- Both result in a key value of 8487168, even though they are at different scales.
