[Jimmy]

hi,

i got Error "wrong Format" when try using 24Bit BMP as Resource
than i have convert to 4Bit and that work ... but no "Transparency" in MENU ...

so what Format can i use in *.RC

Jimmy:
You can upload JPG, PNG, BMP format as follows in your RC

Code: Select all  Expand view  RUN

NamePng RCDATA "myfileimage.png"

Where NamePrn will be the name of the resource
myfileimage.png will be the file on disk

You should not have problems with 24 bit bitmaps.
Yes, for 32 bit alpha bitmaps and other formats (jpg,png,etc) use RCDATA

i have take Bitmap from c:\fwh\bitmaps\32x32\ but still got "Format" Error ...

i have reduce to 8 Bit which work but have "no Transparency" in MENU
btw 32 Bit BCC 7

Yes, for 32 bit alpha bitmaps and other formats (jpg,png,etc) use RCDATA

Import your bmps with Pixelforms and export to bmp with the Premultiplied alpha option.

This folder contains some 32-bit alpha bitmaps also.

If you get the error 17 Invalid bitmap format error, then the bitmap is 32-bit, but definitely not 24/16/8/4/2 bits.

Immediately, change BITMAP as RCDATA in your rc file.

Code: Select all  Expand view  RUN

PHONE RCDATA "c:\fwh\bitmaps\32x32\phone.bmp"

No extra work on your part is required.

Please try this test program:

Code: Select all  Expand view  RUN

#include "fivewin.ch"

function Main()

   local oWnd, oBar

   DEFINE WINDOW oWnd

   // 24 Bit
   DEFINE BUTTONBAR oBar OF oWnd SIZE 64,64 2007 HEIGHT 96
   SET MESSAGE OF oWnd TO "bitmaps" 2007

   DEFINE BUTTON OF oBar RESOURCE "CASCADE" GROUP LABEL "24 Bits"
   DEFINE BUTTON OF oBar RESOURCE "ATTACH"
   DEFINE BUTTON OF oBar RESOURCE "COPY"

   // 32 Bit Alpha bitmaps
   DEFINE BUTTON OF oBar RESOURCE "DOWN" GROUP LABEL "32 Bit Alpha"
   DEFINE BUTTON OF oBar RESOURCE "PHONE"
   DEFINE BUTTON OF oBar RESOURCE "POCKETPC"


   oWnd:nWidth    := 500
   oWnd:nHeight   := 700

   ACTIVATE WINDOW oWnd CENTERED ;
      ON PAINT oWnd:DrawImage( "OLGA", oWnd:GetCliAreaRect():aRect )

return nil
 

rc file

Code: Select all  Expand view  RUN

CASCADE  BITMAP "c:\fwh\bitmaps\32x32\cascade.bmp"
ATTACH   BITMAP "c:\fwh\bitmaps\32x32\attach.bmp"
COPY     BITMAP "c:\fwh\bitmaps\32x32\copy.bmp"

DOWN     RCDATA "c:\fwh\bitmaps\32x32\down.bmp"
POCKETPC RCDATA "c:\fwh\bitmaps\32x32\pocketpc.bmp"
PHONE    RCDATA "c:\fwh\bitmaps\32x32\phone.bmp"

OLGA     RCDATA "c:\fwh\bitmaps\olga1.jpg"
