Four ways to save picture as Tiff in Xojo

Depending on your needs, we can offer four different ways to save a picture in tiff (and other) formats.

NSImageMBS is a high level class for handling images on MacOS and it can save in various formats. CGImageDestinationMBS offers a way to export in something like 20 formats on MacOS and iOS (public.jpeg, public.png, com.compuserve.gif, public.tiff, public.jpeg-2000,, org.khronos.ktx, org.khronos.astc, public.heic,,,, com.adobe.photoshop-image, com.adobe.pdf, com.truevision.tga-image, com.ilm.openexr-image, public.pbm, public.pvr).

For cross platform projects, you can for example try GMImageMBS class, which can write in over 100 formats. If you need tiff specific details, you may want to check our dedicated TiffPictureMBS class, which allows you to control all details and lets you set individual header fields.

[code]Dim p As Picture = LogoMBS(500)

// 1. NSImageMBS

Dim n As New NSImageMBS§
Dim tiff As String = n.TIFFRepresentation
Dim file1 As FolderItem = SpecialFolder.Desktop.Child(“test1.tif”)
Dim b As BinaryStream = BinaryStream.Create(file1)
b.Write tiff

// 2. CGImageDestinationMBS

Dim image As CGImageMBS = CGImageMBS.CreateImage§
Dim file2 As FolderItem = SpecialFolder.Desktop.Child(“test2.tif”)
Dim dest As CGImageDestinationMBS = CGImageDestinationMBS.CreateWithFile(file2, “public.tiff”, 1)

dest.AddImage(image, Nil)

If dest.Finalize Then
// MsgBox “Saved”
MsgBox “Failed to save.”
End If

// 3. GMImageMBS

Dim gmimage As New GMImageMBS§
Dim file3 As FolderItem = SpecialFolder.Desktop.Child(“test3.tif”)

// 4. TiffPictureMBS

Dim t As New TiffPictureMBS
Dim file4 As FolderItem = SpecialFolder.Desktop.Child(“test4.tif”)

t.Pict = p

If t.Create(file4) Then
If t.WriteRGB Then
// ok
End If
End If[/code]

From the above seems you support write to mpg. Presumably this takes a series of images ?

I’d like to record the screen or a portion of it with more control than shelling out to ffmpeg…

This is just the list of coders, I exported.

To create video, you may check our JPEGMovieMBS class.
Or with AVFoundation the AVAssetWriterInputMBS and AVAssetWriterInputPixelBufferAdaptorMBS classes.

Thanks. Forget AV as an end format as it’s huge. Target is mp4.

I would usually just add images to movie and then later recompress it, when things are done.

Do you havecan example of recompression into mp4 Christian ?

see AVAssetExportSessionMBS class website.

There is even a list of examples on the bottom, you may want to check.

Will check it out thanks Christian.
