HSL color adjustment

Rickyngk

Dear,
Thank to Gideros API support RGB adjustment, I save much space to store image. But sometimes, I need HSL adjustment.

Let's see the attachment. If I wanna change color of image (first image), such as to blue, the white border has been changed too (third image). With HSL adjustment, I can keep the border (Second image).

Regards,

You can't do HSL adjustment at the moment, the best you can do is render your font in white and then use the RGB colour modifier to change the colour.

Alternatively you can split off the font border and draw it separately after rendering the font.

I have written a hsl->rgb->hsl->col->hsl plugin which does all of the maths but as everyone has already stated the only colour shift available to us is the setColorTransform which uses RGBA and as such will transform all colours in the sprite. I knocked together a proof of concept demo using my plugin and got the results I was expecting, but unfortunately not what you require.
