[Solved] 24 bit Windows bitmap

Post by Lee7 »

In order to work on my GPS, custom symbols need to be saved in '24-bit Windows-style bitmap format'. I can't see how to do this in GC11? Can anybody assist please?

Normally just use an image with millions of colors without alpha channel. That uses 24 bit for the image data.
Just save that as a BMP and you get a 24 bit BMP.

Thanks - how do I do that within GC? I can't see any 'save as...' options, in 'picture > colors' there are colour depth options, but nothing that matches what you've said? These are tiny images, up to 32x32 pixels, so I need to make it from scratch. When I've tried to edit one that works, it stops working, so I've changed the bit-depth inadvertently it seems?

2. Check if an alpha channel exists.
The menu looks like this if there is no alpha channel:

3. Save as
Select BMP and click onto Options.
Select NONE for the compression.

Thank-you very much, I'll give it a try. This sort of support is why I'm still a happy user after nearly 23 years.... :)

That didn't seem to work.... this is for GPS receiver icons, 32x32 pixel.
I did the above and saved the file, but the GPSr refused to acknowledge the symbol. I ran the bmp through this little online converter, and it worked fine...??
