asked on
bitmap with same color controls
I have a bitmap of a block diagram on a form which has a grey background. Placed on top of the bitmap are check boxes, comboboxes, labels, and other controls.
The problem I'm having is when the program is loaded on other computers with different color settings. The clBtnface color is a different shade of grey. Which makes the form look really cheesey.
I have tried saving the bitmap with different color levels, i.e. 16, 256, 24Bit. The setting needs to be the same as the computer your using at the time to come close to matching the colors.
What is the common way to do somthing like this. Use a GIF with transparent backgound? Set a constant and assign the color I need for each control? If this is the answer then do I assign the color in the form.create procedure? Will it accept a color thats not in the property list?
Hope this makes sense.

Also, yes, you can assign colors thats are not (constants) in the property drop dpwn list.

The clGray is too dark for my needs and the other default colors don't work. Should I find the hex value for LtGrey for 256 colors and set the form color property to this?
Is there an easy way to find the hex color setting?
Is there an easy way to find the hex color setting?
convert a hex color string to a TColor variable? Try this:
{
sColor should be in XXXXXX format
(X being a hex digit)
}
function
HexToTColor( sColor : string )
: TColor;
begin
Result :=
RGB(
{ get red value }
StrToInt( '$'+Copy( sColor, 1, 2 ) ),
{ get green value }
StrToInt( '$'+Copy( sColor, 3, 2 ) ),
{ get blue value }
StrToInt( '$'+Copy( sColor, 5, 2 ) )
);
end;

Remember, for example for checkbox You should set not only Color but also Font.Color
Here is an entire list of HEX colors

? why not paint your bitmap-background transparent ?
use the onpaint event for painting yourself for ex.
(there are also other methods)
no time for a sample yet,
but other experts may pickup this suggestion,
lately tomorrow myself, if this will solve your problem

Well, I downloaded a color pallet program and it told me my bitmap background color was 0xc0c0c0 which turns out to be clSilver. I changed the form to this color and everything matches except the menu bar.
I still need to see what it looks like on other PCs.
I think converting to Gif89 and making the backgound transparent is the way to go.
