Using floats should not be a problem as BitBlt will round these to integers:

| canvas image |

canvas := FormCanvas extent: 100.1@100.2.

canvas fillColor: Color gray.

image := Smalltalk ui icons iconNamed: #error.

canvas image: image at: 2.5@3.9 sourceRect: (1.2@5.3 extent: 42.1@43.4) rule: 34.

canvas form inspect.

Best regards,

Henrik
