Icons and Magenta Transparency

PaulB2005 · Posted: Fri Apr 04, 2008 10:01 pm Post subject: Icons and Magenta Transparency

I have made a custom BMP file 24x24 for use with my own POIs. Until last week it was a magenta (255,0,255) square with a green circle which displayed as a green circle on the map.

Now since the new POILoader release it displays the icons as magenta squares with a green circle. Whatever i do i can't seem to design an icon with transparency...

Weird thing is i took GerryC's improved Speed Camera icons and made the white corners transparent so they have a rounded corner effect, and the transparency still works on those icons! I hadn't changed either icon and the only thing that had changed was the POILoader.

I'll get some screen shots tomorrow, but is any one else having the same problem?

Any tips as to where i might be going wrong? Type of icon etc?

OK so POILoader doesn't seem to be to blame. Reverted back to 2.4.2 and same problem.

What i don't understand in that I've used the Magenta colour to round the corners of GerryCs icons and they seems to work fine.

In the screenshot above the white tips on GerryCs icons are transparent because i've coloured them magenta, but my green circle is filled with Magenta.

I've tried starting with a new 24x24x8 icon. I must be doing something wrong if it works with one icon and not the other.

Here are two fictitious cameras. One with the original GerryC icon with white corners (Left) and one with my Magenta (transparent) corners (Right). Both are loaded at the same time.

One day my green circle worked the next it didn't....

Any ideas?

Paul, Mine were made in Paint (yes really Smile

) and saved in 8 bit colour (256 colours). It could be that the icons you are making have a different colour depth etc.

By the way, thanks for showing me your creations a while ago - when TomTom gets their act together, I may make transparent ones myself. As a better improvement, I'd suggest making the lightest red on the outside transparent as well - will look better with the dark background. Cool

This problem has bugged me ever since I've had a Nuvi. Have just tried your 8-bit solution, but still can't produce 'invisible.' What luminance and saturation settings are you guys using?

ETA Hmmm...just realised you can't change those settings without changing the colour, so don't really know where I am still going wrong.

Sussed it. Just realised I was using a really old version of POILoader.

Doh!
