2026-04-22VirtualKeyboardFeaturePkg: convert SimpleIcon and FullIcon BMPs to palettedJames Lu2-0/+0
Follow-up to the 4-bit keyboard BMP conversion in PR #969 for the remaining two icon assets in VirtualKeyboardDxe. SimpleIcon.bmp uses only 2 unique colors (pure black/white); convert to 1-bit paletted BMP for a byte-level lossless reduction. FullIcon.bmp uses 198 unique colors; convert to 8-bit paletted BMP for a byte-level lossless reduction (198 < 256 palette entries, no quantization required). EDK2 BaseBmpSupportLib already supports 1-bit and 8-bit uncompressed BMP (TranslateBmpToGopBlt handles both BitsPerPixel values). Per-file size reduction (24-bit -> target): SimpleIcon.bmp: 2814 -> 182 (1-bit) FullIcon.bmp: 5454 -> 2878 (8-bit) Pixel dimensions and visual layout are unchanged.

2026-04-02VirtualKeyboardFeaturePkg: convert keyboard BMPs to 4-bit paletteJames Lu3-0/+0
Convert the three VirtualKeyboardDxe keyboard bitmap assets from 24-bit BMP to 4-bit paletted BMP. Each bitmap uses fewer than 16 unique colors after median-cut quantization, so the 16-color palette is sufficient. Pixel dimensions and visual layout are unchanged. EDK2 BaseBmpSupportLib already supports 4-bit uncompressed BMP (TranslateBmpToGopBlt handles BitsPerPixel==4). Per-file size reduction (24-bit -> 4-bit): CapitalLetterKeyboard.bmp: 330454 -> 55318 DigitKeyboard.bmp: 330454 -> 55318 SimpleKeyboard.bmp: 30054 -> 5318 Signed-off-by: James Lu <james.lu@intel.com>
2024-11-28Pkg-Module: Features/VirtualKeyboardDxe PART 2Darbin Reyes1-1/+1
The Keyboard.c driver did not include ScanCodes like F1,F2,F12,etc. and UnicodeChars like Backspace, Tab in VK_NOTIFY NotifyList which is why these keys were not getting registered and not getting pushed in the KeyBuffer stack which resulted in undefined behavior of continuous backspace and not recognizing the relevant key push after the buffer overflow condition.
