/* Frame buffer stride
|
|
*
|
|
* Stride describes the amount that you need to increment to get to the next
|
|
* line. For screens that have the pixels in contiguous horizontal strips
|
|
* stride should be equal to the image width.
|
|
*
|
|
* For example, if the screen pixels are layed out as follows:
|
|
*
|
|
* width0 width1 width2 widthX-1
|
|
* ------ ------ ------ ------------------ --------
|
|
* height0 | pixel0 pixel1 pixel2 ----------------> pixelX-1
|
|
* height1 | pixelX
|
|
*
|
|
* then you need to add X pixels to get to the next line. (the next line
|
|
* in this case is height1).
|
|
*
|
|
* Similarly, if the screen has the pixels in contiguous vertical strips
|
|
* the stride would be equal to the image height.
|
|
*
|
|
* For example if the screen pixels are layed out as follows:
|
|
*
|
|
* width0 width1
|
|
* ------ ------
|
|
* height0 | pixel0 pixelY
|
|
* height1 | pixel1
|
|
* height2 | pixel2
|
|
* | | |
|
|
* \|/ | \|/
|
|
* heightY-1 | pixelY-1
|
|
*
|
|
* then you would need to add Y pixels to get to the next line (the next
|
|
* line in this case is from width0 to width1).
|
|
*
|
|
* The remote might have a different stride than the main screen so the screen
|
|
* number needs to be passed to the STRIDE macro so that the appropriate height
|
|
* or width can be passed to the lcd_bitmap, or lcd_remote_bitmap calls.
|
|
*
|
|
* STRIDE_REMOTE and STRIDE_MAIN should never be used when it is not clear whether
|
|
* lcd_remote_bitmap calls or lcd_bitmap calls are being made (for example the
|
|
* screens api).
|
|
*
|
|
* Screen should always use the screen_type enum that is at the top of this
|
|
* header.
