iOS Question how make file gif in b4i ?

[naifnas]

hello
how make file gif in v4i ?
like this in b4a

        Dim gif As RSAnimatedGifEncoder

    Dim out2 As OutputStream
    out2 = File.OpenOutput(dir , "1.gif", False)
    gif.start(out2)
    gif.addFrame(btmp1)
    gif.addFrame(btmp2)
    gif.finish

There is no similar library in B4i. With some work it should be possible to implement this format yourself.

so please I can make gif by this

Public Sub ImageToBytes(Image As Bitmap) As Byte()
Dim out As OutputStream
out.InitializeToBytesArray(0)
Image.WriteToStream(out, 100, "JPEG")
out.Close
Return out.ToBytesArray
End Sub

Public Sub BytesToImage(bytes() As Byte) As Bitmap
Dim In As InputStream
In.InitializeFromBytesArray(bytes, 0, bytes.Length)
Dim bmp As Bitmap
bmp.Initialize2(In)
Return bmp
End Sub

Dim out As OutputStream
out = File.OpenOutput(File.DirRootExternal,"main.gif", False)

[B4X] Bytes To File

This code is no longer needed. Use File.WriteBytes / ReadBytes. Write an array of bytes to a file and read a file into an array of bytes. Sub BytesToFile (Dir As String, FileName As String, Data() As Byte) Dim out As OutputStream = File.OpenOutput(Dir, FileName, False)...

sorry, i dont understand the question.

you have an example that is included and shows how to create the gif. the gif is stored in File.Dirdocuments and you can then share it or load or what ever you want to do.
to create the gif you just need to create a list and load it with the frames (images). the type should be Bitmap. then you create the gif bycalling the .create method and you put the name of the gif and the speed of the gif between 0 to 1 (Float)

thats it, very simple.

 

[naifnas]

I already use this example ..
very nice and work
