Any infos about function < C5RoundRect > ? ( solved )

[ukoenig]

Hello,

I tested the function C5RoundRect
but couldn't find anything about possible alterations to change the backgroundcolor or maybe to make it transparent inside. The circle itself, is the selected pencolor and size.
Where does this function come from ?

A test, merged to a image



A sample of usage
( merging different objects : alphablended bmp and free text )
It is possible to change the form from circle to rounded box or ellipse



another combination
a inserted, created signature, a selected image with a added box ( defined pensize and color ).
the pensize and color can be changed at runtime.



Best regards
Uwe

Uwe,

That function is just a wrapper for the Windows API function RoundRect()

In order to use a brush with it, you should first create the brush and select it to the current hDC and later on, save the current brush using hOldBrush := SelectObject( hDC, oBrush:hBrush ), paint, select the previous brush with SelectObject( hDC, hOldBrush ) and finally destroy the brush ( oBrush:End() )

Antonio,

THANK YOU VERY MUCH !
it works fine that way.
Now I understand the logic.

it can be a brush-combination :

DEFINE BRUSH oBrush1 STYLE NULL
DEFINE BRUSH oBrush2 COLOR 255

with some calculations, it will be possible, to get some nice effects.

I will add four possible forms :

1. round filled ( mouseclick Top / Left for position and a defined size )
2. free form filled ( mouseclick Top / Left and Bottom / Right )
3. round transparent
4. free form transparent

the sample shows a inserted alphablended image
The three textlines are converted from a multiline get.



17 possible styles :

Antonio,

all four forms are working perfect now.
Circles are a ONE-click solution on image Top / Left
Ellipses are a TWO-click solution on image Top / Left and Bottom / Right
A circle works like a image. The basic-diameter can be define inside the extra-dialog.
Inside the Main-painting area, You can select a resize-factor of the defined size and any pensize and color.
