Number
isn't always reliable (consider video projectors) but can still be
used to determine the pixel aspect ratio.
- Arguments for:
-
- X supports a similar query with DisplayWidthMM(), DisplayHeightMM().
- If this information can be easily queried with EDID, why not
- make it available to the user?
-
- Arguments against:
-
- Historically, these values aren't always accurate. Also, they're
- not always applicable to the display device.
-
- Other options:
-
- Perhaps just a pixel aspect ratio should be supported. [M. Danzer]
-
- Postpone for a future extension, if needed. [A. Jackson]
+ Resolution: Omit. The EGL 1.2 specification includes queries for
+ the display resolution and pixel aspect ratio.
6. Should detailed mode timing information be exposed by this API?
14. What if the physical screen size can't be determined? Should
a query of EGL_PHYSICAL_SIZE_MESA return [0,0]?
- TBD.
+ Obsolete: EGL_PHYSICAL_SIZE_MESA not used.
15. Suppose the device's number of RAMDACs is different from the
EGL_SCREEN_COUNT_MESA
EGL_SCREEN_POSITION_MESA
- EGL_PHYSICAL_SIZE_MESA
EGL_SCREEN_BIT_MESA
EGL_SCREEN_POSITION_GRANULARITY_MESA
EGL_SCREEN_POSITION_GRANULARITY_MESA
Returns the granularity, in pixels, for
which the screen position is constrained.
- EGL_PHYSICAL_SIZE_MESA Physical width and height of the screen
- in millimeters
Any other token will generate the error EGL_BAD_ATTRIBUTE.
10. 10 August 2005 - BrianP
Added EGL_SCREEN_POSITION_GRANULARITY_MESA.
+ 11. 27 January 2006 - BrianP
+ EGL_PHYSICAL_SIZE_MESA removed since EGL 1.2 has a similar feature.
