| 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). |
