2020-01-14libpayload: cbgfx: Support drawing a box with rounded cornersYu-Ping Wu
A function draw_rounded_box() is added to draw a box with rounded corners. In addition, this function is different from draw_box() in 2 ways: - The position and size arguments are relative to the canvas. - This function supports drawing only the border of a box (linear time complexity when the thickness is fixed).

2019-08-08libpayload: cbgfx: Allow rotation of the displayNicolas Boichat
Sometimes the display native orientation does not match the device default orientation, so allow rotation of the framebuffer before it is displayed on screen. set_pixel now take coordinates in the rotated coordinate system, and converts the coordinates before writing to the framebuffer. Also, screen.size now matches the rotated system (_not_ the framebuffer size). BUG=b:132049716 TEST=Boot krane, see that FW screen is orientation properly.

2017-04-17libpayload: cbgfx: Show square images on portrait displaysJulius Werner
CBGFX currently doesn't support portrait screens at all. This will have to be fixed eventually but might take a bit of effort. As a first step to make devices with a portrait panel somewhat usable, this patch will just force a square canvas on these panels and keep the bottom part of the screen black. Also switch set_pixel to calculate framebuffer position via bytes_per_line instead of x_resolution. This is supposed to be the canonical way to do that and may differ in cases where the display controller requires a certain alignment from framebuffer lines.

2016-07-02cbgfx: Use memset() for faster screen clearing if possibleJulius Werner
cbgfx currently makes a separate function call (recomputing some values) for every single pixel it draws. While we mostly don't care that much about display speed, this can become an issue if you're trying to paint the whole screen white on a lowly-clocked Cortex-A53. As a simple solution for these extreme cases, we can build a fast path into clear_screen() that just memset()s the whole framebuffer if the color and pixel format allow it. BUG=chrome-os-partner:54416 TEST=Screen drawing speed on Kevin visibly improves (from 2.5s to 3ms).

2015-10-27cbgfx: add pivot option to draw_bitmapDaisuke Nojiri
This change adds 'pivot' option to draw_bitmap. It controls the point of the image based on which the image is positioned. For example, if a pivot is set to the center of the image horizontally and vertically, the image is positioned using pos_rel as the center of the image. This feature is necessary, for example, to place a text image in the center of the screen because each image has a different width depending on the language. This change also makes draw_bitmap accept both horizontal and vertical size. If either of them is zero, the other non-zero value is used to derive the size to keep the aspect ratio. Specifying the height is necessary to keep font sizes the same when drawing text images of different lengths. draw_bitmap_direct is a variant of draw_bitmap and it draws an image using a native coordinate and the original size (as opposed to the location and the size relative to the canvas). CL:303074 has real use cases.
