[Ovmsdev] App vehicle images

[Mark Webb-Johnson]

Chris,

Old eMail on this below. Since then, I've got this done for the other cars and it seems to work well. Now working on integrating to the Apps.

Regards, Mark.

I've spent some time trying this tonight.

I took the basic twizy image, magic wand selected the paint colour part of the vehicle, then cut and paste that as a new layer. I then converted the paint colour layer to grayscale.

Next, using the colorise filter, applied to the grayscale paint layer, I tried colouring it with a colour wheel. It worked beautifully. I could generate all the possible colours, and the paint highlights and shadows looked really good.

I'll now see if I can do this programatically in iOS. If I can, we can dramatically reduce the amount of artwork required for each vehicle. Just a couple of base image layers and a 4-byte ARGB code for each standard vehicle (plus a colour wheel for users to choose their own custom colour).

Proof of concept - some colour suggestions for Renault:

Base grayscale layer:

 +  = 

Colorised:

I'm guessing your going to do something like a masking image with a transparent silhouette on a given coloured background,  then overlayed with a semi transparent detail layer? A stack of PNGs would do the trick.

They are just too large (13MB+ already!), so I am working on a better way of handling the multiple colours and making it easier to add them to the Apps. Once I have this working, I'll let you know what format we need the images in.
