Problem Using DC_BitmapTransparentColor with DCPUSHBUTTONXP

[digitsoft]

hello Roger
because if I am using DC_BitmapTransparentColor({255, 255, 255}) in DCPUSHBUTTONXP CAPTIONARRAY the photos are not transparent

I think this is an Xbase++ problem.

Are you saying that only {255,255,255} has the problem?

I'm using this color for transparency {255,255,255} but it doesn't work for me


DC_BitmapTransparentColor( {255, 255, 255} )
@ 0.01+xRow,nCol+0.2+xCol DCPUSHBUTTONXP ;
CAPTIONARRAY aCaptions ;
SIZE 13.51, 4.35 ;
COLOR GRA_CLR_WHITE, aMenuVtaRapida[5] ; && GraMakeRGBColor({30,144,255}) ;
MOUSECOLOR GRA_CLR_BLACK, GraMakeRGBColor({245,205, 75}) ; && GraMakeRGBColor({30,144,255}) ;
MOUSEFONT '11.Calibri Bold' ;
BORDERCOLOR GRA_CLR_BLACK ;
ACTION PushMe( aApp,aMenuVtaRapida[1] ) ;
WHEN _When( aApp, !EMPT(aMenuVtaRapida[1]) ) ;
TOOLTIP aMenuVtaRapida[2] ;
PARENT oToolBarTop ;
MESSAGE aMenuVtaRapida[2] INTO oMsgBox

I think this is an Xbase++ problem.

Are you saying that only {255,255,255} has the problem?

Any chance to turn those bitmaps into icons, Nolberto? This works ways better.

Your bitmaps may get scaled, and that can have effects to the color pattern.

Thanks tom
Because of your Answer, I cannot do this option because that photo is what the user assigned to the Product and can change.

If your customer is the creator of the bitmap, then there is nothing that you can do to handle transparency.
The transparent color is determined by the creator of the bitmap.

You are adding to the complexity of your program by requiring that background colors be transparent.
I suggest that you paint the bitmaps on the buttons in the way that the customer creates the bitmaps.

Thanks Roger
for his answer but I tell the client to put a white background on the maps
but it does not work.

Send me one of the bitmaps that has the white background.

What the client does is copy the photo from the internet
I attach the Image

Send me one of the bitmaps that has the white background.

hi,

i have test your "salsa linda.jpg" and use this Code

Code: Select all

PROCEDURE Main
LOCAL oBMP, cTitle := "test"

   oBMP := XbpBitmap():new():create()
   oBMP:Loadfile("salsa linda.jpg")

   oBMP:transparentClr := oBmp:getDefaultBGColor()

   NewGFXDocument( oBMP, cTitle )
RETURN

and got this
