I need to set the ImageToolbar Button COLOR to a specific TColor.

But how can I calculate ImageEnViewToolbar1.ImageHue from a TColor?

I have tried:

ColorToHSV($ECAC00, h, s, v);


...and then using the h value, but it doesn't work.

Hi Peter

Unfortunately is not that simple because the toolbars glyphs already have color, so you can only adjust the existing hue.

Hi Nigel,

the documentation says:

-180 to +180 Default color is modified by the specifed hue

So which value in the range between -180 and +180 is most similar to the TColor value of $ECAC00?

Hi Peter

Save one of the images above and open it in the \ImageEditing\CompleteEditor\PhotoEn.dpr demo.

Then select Tools > Adjust Image, "HSV" tab and adjust the Hue value to find a color you like.
