Code (fw): Select all Collapse

aBmp := FW_ReadImage( ..... )
DrawBitmap( hDC, aBmp[ 1 ], nRow, nCol )
PalBmpFree( aBmp )

Nages,
on ::acBitmaps I Insert an array with many png files

for n = 1 to len( ::acBitmaps )
aadd( ::aBitmaps, FW_ReadImage( ::acBitmaps[ n ] ) )
next n

then

xbrowser ::aBitmaps

give me this

if I use aadd( ::aBitmaps, ::ReadImage(::acBitmaps[ n ] ) )

then give me the right list

on method paint I have

DrawBitmap( ::hDC, ::aBitmaps[ max( ::nActual , 1 ) ], nRow, nCol, ::nWBmp, ::nHBmp, SRCCOPY )

because before the class run with only bmp file

how I can to converte it to run with png files ?

This is wrong

Code (fw): Select all Collapse

FW_ReadImage( ::acBitmaps[ n ] )

Correct

Code (fw): Select all Collapse

FW_ReadImage( NIL, ::acBitmaps[ n ] )

FW_ReadImage reads all image files including png, jpg, etc.

You can use DrawBitmap() if you have a personal preference, but FW_DrawImage( hDC/oWnd, uImage, aRect, ... ) is more advanced than all other image drawing functions.
