Is there codec for FMX, Android Bitmap ?

[Turan Can 3]

Hi All,

 

FMX Project.

"TBitmapCodecManager" doesn't support bitmap on Android?

These are the only ones that come when I enter this "TBitmapCodecManager.SaveToStream(" method.

POSIX

jpg, tif, png

 

WINDOWS

jpg, tif, png, bmp ...

 

 

for Descriptor in FBitmapCodecClassDescriptors do

if (SameText(Extension, Descriptor.Extension, loUserLocale) or SameText('.' + Extension, Descriptor.Extension,  loUserLocale)) and Descriptor.CanSave then

 

--------------------------------------------------------------------

uses FMX.Graphics, FMX.Surfaces;

 

var

  Stream: TMemoryStream;
  Surf: TBitmapSurface;

begin

                Stream := TMemoryStream.Create;
                try
                  Surf := TBitmapSurface.Create;
                  try
                    Surf.Assign(FBmpNew);
                    //TBitmapCodecManager.RegisterBitmapCodecClass('.bmp', 'bmp', True, ......??? 
                    TBitmapCodecManager.SaveToStream(Stream, Surf, '.bmp');
                  finally
                    Surf.Free;
                  end;
                  Stream.Position := 0;
                  Stream.SaveToStream(FStream);
                finally
                  Stream.Free;
                end;

No, FMX does not support the BMP format on Android by default.  The documentation is quite clear on which formats are implemented on each platform:

 

 

If you want to use BMP on Android, you can write your own class derived from TCustomBitmapCodec to handle that, and then register it with TBitmapCodecManager at runtime.
