Colors (SOLVED)

Postby ctoas » Sun Jun 13, 2021 11:27 pm

Hello friends!

I need a little help, I have a color in decimal (for example 6736896). How to get tones above or below, what's the logic?

Thanks

Christiano,

? hb_NumToHex( 6736896 ) => 0x66CC00 (hexadecimal)

? hb_NumToHex( hb_bitAnd( 6736896, 0xFF0000 ) / 0xFF00 )
? hb_NumToHex( hb_bitAnd( 6736896, 0x00FF00 ) / 0x00FF )
? hb_NumToHex( hb_bitAnd( 6736896, 0x0000FF ) )

In FWH\include\colors.ch there is a:

#translate RGB( <nRed>, <nGreen>, <nBlue> ) => ;
( <nRed> + ( <nGreen> * 256 ) + ( <nBlue> * 65536 ) )
regards, saludos

Hi Uwe, thanks for replying.

I'm adjusting the visual part of my calendar, as the user can change the predominant color of the screen, the calendar has differences in the colors of today, Sundays and holidays. In the way I'm doing it, in some situations it's out of color.

So I want to calculate to get a few shades above or below the predominant color.

Maybe useful for You

paint colors from a given DEC or RGB-value
or use predefined colors
You can save and restore 4 colors
adjust the color with the slider or click inside the image
as well You get the colornames
the ??? buttons will paint the color and shows the values

Hi.

I haven't touched it yet but that's almost what I need when using the slider but automatically, I think it would be more interesting in my case although I could do something similar and let the user choose the tone they prefer.

Would it be possible to share so you can have a beginning?

I must disagree, the correct formulas are:
? hb_NumToHex( hb_bitAnd( 6736896, 0xFF0000 ) / 0x10000 )
? hb_NumToHex( hb_bitAnd( 6736896, 0x00FF00 ) / 0x100 )
? hb_NumToHex( hb_bitAnd( 6736896, 0x0000FF ) )
or better
? hb_NumToHex( hb_bitShift( hb_bitAnd( 6736896, 0xFF0000 ) ,-16) )
? hb_NumToHex( hb_bitShift( hb_bitAnd( 6736896, 0x00FF00 ) ,-8) )
? hb_NumToHex( hb_bitAnd( 6736896, 0x0000FF ) )

I added some new options

1, testing the color as a dialog-brush ( ON / OFF )
2. saving a color to INI pos. 1, this color is displayed at new start
3. copy to clipboard
4. some internal fixes

ctoas
what sections do You need ?
I can delete the unneeded parts for better reading.

I tested and added a horizontal solution
a little colorpicker and control-fields of the pickpositions as a info
are included as well.

Because of the 2. slider it is posssible to compare 2 colorlevels
like the image shows ( bright and dark )
< Create > a new color will update both sliders and all fields

I think it will give You the basics to create Your own tool.

Image

Download
http://www.service-fivewin.de/DOWNLOADS/CAdjust3.zip

the needed calculations are included inside the prg
Code: Select all  Expand view

// calculation vertical
// ------------------------
// imageheight = 300
// sliderheight = 330
// slidertop = imagetop - 15
// slidermarks = 11 = 10 spaces
// slider-pixelrowpos = slider rowpos * 10
// sliderpos on imageclick = imagepixelpos / 300
// imagepos on sliderclick = sliderpos * 30
// image-columnpos = imagewidth / 2 = 25

// calculation horizontal
// --------------------------
// imagewidth = 340
// sliderwidth = 370
// sliderleft = imagejeft - 15
// slidermarks = 11 = 10 spaces
// slider-pixel-colpos = slider colpos * 10
// sliderpos on imageclick = imagepixelpos / 340
// imagepos on sliderclick = sliderpos * 34
// image-rowpos = imageheight / 2 = 22
