BmpToRaw

BmpToRaw is a lightweight software application designed specifically for helping you convert Windows bitmaps to RAW files which are used as logos or sky graphics in Tomb Raider Level Editor.

Portable running mode

Portability comes with several advantages. You can bypass the installation process and run the utility by simply opening the EXE file.
What’s more, you can store the tool on any USB flash drive or other devices and carry it with you. Good news is that the app doesn’t leave any entries in the Windows registry and write configuration data in your system, so you may run it without administrative privileges.

Minimalist looks

You are welcomed by a clean and simplistic GUI that embeds only a few configuration settings that you can play with. Files can be added in the working environment using the built-in browse button (there’s no support for drag-and-drop).

Conversion capabilities and view options

The conversion process can be carried out with minimal user intervention. You only need to pick the output file format, namely RAW (logos and sky graphics) or PAK (logos), as well as enter the filename and directory.
What’s more, BmpToRaw gives you the possibility to enable the transparency mode in order to show the black parts of a logo as transparent (this option has no effect on the RAW and PAK file that can be saved on your system). Last but not least, you may view RAW files and compressed logos (PAK items), and calculate the average color of the loaded bitmap.
The application doesn’t offer support for batch processing, which means you cannot convert multiples files at the same time. The settings are not saved, so you need to configure the dedicated parameters each time you open the utility.

Bottom line

All things considered, BmpToRaw comes with a handy suite of features for helping you perform conversion tasks, and can be handled by all types of users, regardless of their experience level. On the downside, it hasn’t been updated for a long time, so it may cause compatibility issues on newer operating systems.
