MUI_HEADERIMAGE_BITMAP not working

Hello everyone.

I am trying to insert my custom images in the installer and I create a 150x57 pixels image (nsis.bmp) to use as MUI_HEADERIMAGE_BITMAP and it does not work. I also create a 164x314 pixels image (win.bmp) for MUI_WELCOMEFINISHPAGE_BITMAP and it does not work either.

I know the configuration file is ok because if I use an old image that came with the installer I can see it, but if I replace it it does not work.

I create the images with GIMP in Linux.

I use RGB.

this are my lines

and a bit further down I have:

Can anyone help me?

Thanks

Solved. Just had to change the color palette to 256 colors

The MUI uses the LoadImage Windows function. I'm guessing a 24bpp should work but you need to save it in the correct BMP format. It is not unusual for *nix tools to save BMPs in a undocumented BMP version that Windows is not always compatible with. Choose the Windows v3.x format (BITMAPCOREHEADER or BITMAPINFOHEADER) if possible...

Creating the file using Imagemagic...

According to


Imagemagic produces the correct file format for this if you prefix the filename with "BMP2:"

Which created a file for me that would display.
