[Qgis-developer] Is there any random part process the label engine?

[Denis Rouzaud]

Hi all,

Everything's in the subject: is there any random process in the label 
engine?

In other words, if I render one million times the same extent with the 
same layers, the same symbology, will I have everytime the same image?

(if it is true, I could use an efficient synchronization process of the 
tiles generated by QTiles for mobile devices: generating a md5 on the 
image, and only upload new tiles).

Thanks for your answer,

Denis
