You can use any image format supported by imagemagick, a list of which
|
|
can be found [here](https://imagemagick.org/script/formats.php).
|
|
|
|
The build process will automatically convert this to the format that
|
|
edk2 requires, which is an uncompressed BMP, in BMP3 format. It does
|
|
this using imagemagick (`convert splosh.bmp BMP3:splash.bmp`).
|
|
|
|
The newly formatted file will be the dimensions size as the original
|
|
one.
|
|
|
|
The build process will automatically do this conversion, so it can
|
|
be supplied with any format that imagemagick can process (which is
|
|
pretty much any!).
|
|
|
|
This image will also be used as the BGRT boot image, which may
|
|
persist through your OS boot process.
|
|
|
|
See ACPI spec 6.3, 5.2.22 Boot Graphics Resource Table (BGRT), and
|
|
Microsoft's documentation on BGRT positioning:
|
|
Docs/Windows/Windows Drivers/Bring up guide/Boot screen components

Accordingly, the image used should be no taller/wider than 40% of

the display panel's native pixel height/width (or resolution set).
