Filled vector becomes white for some colours

[serhii-londar]

Hi, I've faced the issue with setting fill colour for vectors with the alpha component. For some colours it becomes white. I'm using WhirlyGlobe 2.6.7 . The code for adding vectors is following:

- (NSArray *)addFilledVector:(MaplyVectorObject *)vecObj
                       viewC:(MaplyBaseViewController *)baseViewC {

    [vecObj subdivideToGlobe:0.0001];

    NSDictionary *dict = @{
        kMaplyColor: [UIColor colorWithRed:0.929412 green:0.305882 blue:0.317647 alpha:0.1],
        kMaplyFilled: @YES,
        kMaplyEnable: @YES,
        kMaplyFade: @0,
        kMaplyDrawPriority: @(kMaplyVectorDrawPriorityDefault + 1),
        kMaplyVecCentered: @YES,
        kMaplyWideVecEdgeFalloff: @(1.0),
        kMaplyWideVecJoinType: kMaplyWideVecMiterJoin,
        kMaplyWideVecCoordType: kMaplyWideVecCoordTypeScreen,
        // More than 10 degrees need a bevel join
        kMaplyWideVecMiterLimit: @(1.01),
        kMaplyVecWidth: @(5)
    };

    MaplyComponentObject *obj1 = [baseViewC addVectors:@[vecObj] desc:dict mode:MaplyThreadCurrent];
    return @[obj1];
}

When I set kMaplyColor: [UIColor colorWithRed:1 green:0 blue:0 alpha:0.1], it works fine and result is the following(pay attention to circle):

But, when I set kMaplyColor: [UIColor colorWithRed:0.929412 green:0.305882 blue:0.317647 alpha:0.1], it fill vector with white color(pay attention to circle):

Can you help me with that issue?

You'll want to multiply the alpha through the rest of the color.

You'll want to multiply the alpha through the rest of the color.

@mousebird Sorry, but I didn't get it.

Multiply the rest of your color values by 0.1

Ok, will try. Thank you!
