int seGetBytesPerScanline(int * pBytes)
int seGetScreenSize(int * Width, int * Height)
Description: This routine sets the display color depth.
Parameter:
Return Value: ERR_OK
Description: This function reads the S1D13705 registers to determine the current color depth and
Parameters: pBitsPerPixel
Return Value: ERR_OK
Description: Determines the number of bytes per scan line of current display mode. It is assumed
Parameters: pBytes
Return Value: ERR_OK
Description: Retrieves the width and height in pixels of the display surface. The width and height
Parameters: Width
Return value: ERR_OK
After performing validity checks to ensure the requested video mode can be set the
appropriate registers are changed and the Look-Up Table is set its default values
appropriate to the color depth.
This call is similar to a mode set call on a standard VGA.

ERR_FAILED
1) the desired frame rate may not be attainable with the specified input clock
2) the combination of width, height and color depth may require more memory than
returns the result in pBitsPerPixel.
that the registers have already been correctly initialized before seGetBytesPerScan-
line() is called (i.e. after initializing the HAL, setting the Display mode and adjusting
the bits per pixel or other values).
The number of bytes per scanline will include non-displayed bytes if the screen
width is greater the display width, or in Default SwivelView Mode.
are derived by reading the horizontal and vertical size registers and calculating the
dimensions. Virtual dimensions are not taken into account for this calculation.
When the display is in SwivelView mode the dimensions will be swapped. (i.e. a
640 480 display in SwivelView mode will return a width of 480 and height of 640).
Height
is available on the S1D13705.
- pointer to an integer to receive the display width
- pointer to an integer to receive the display height
- the operation completed successfully
- desired color depth in bits per pixel.
- Valid arguments are: 1, 2, 4, and 8.
- operation completed with no problems
- possible causes for this error include:
- pointer to an integer to receive current color depth.
- return values will be: 1, 2, 4, or 8.
- operation completed with no problems
- pointer to an integer to receive the number of bytes per scan line
- operation completed with no problems
