QGIS Labels Rotation

I have imported some OS MasterMap data into QGIS 3.2 and have labelled the Cartographic Text dataset. This dataset has a rotation field, populated with various angles of rotation depending where they are to be positioned with relation to roads and buildings. However, when I choose this column under Data Defined Placement, it seems to be rotating the labels in the wrong direction.



Is there a way to tell QGIS to treat the angles differently, as you can in ArcGIS (geographic or arithmetic)?

To use an expression to control label rotation, choose "edit" from the data defined override menu.



enter image description here



If all of your angles are positive numbers, use this expression to make them negative:



concat('-', to_real('fieldname'))


If your angles include positive and negative values, use this expression:



 to_real('fieldname') * -1


If your field is already in numerical format you can leave out the to_real() function.

    i'd also check the field type in the layer properties, if it's a string you may need to convert it to an integer.

    Thanks @StevenKay, I incorporated your suggestion into my answer. I used to_real() instead of to_int(), in case their angles require decimal place specificity.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
