Printing an exinsting tiff file from VB6

[muthuivs]

Hi Guys/Gals,

I am trying to print a tiff image using vb6, any Idea how to do this by using somekind of print function and calling the tiff file that needs to be printed. EG: I have 101.tiff saved in c:\Scans, and I need vb code to send this to the printer by clicking a button on my form. Any help would be deeply appreciated. Thanks

VB doesn't support TIFF images. You'd have to find a conversion, or else use another app to print it.

As dglienna says, VB doesn't directly support TIFF. However, GDI+ does, and I've covered how to use GDI+ from VB to load TIFFs in the past. Just do a keyword search in this forum.

Thsnks for the feedback, I guess I will save the documents as bitmaps for dispaly and printing. Any Idea how to send it to the printer though?

>I will save the documents as bitmaps

Why? Is the GDI+ stuff more complicated than you want (GDI+ is part of Windows nowadays)?

Not really, I haven't had a chance to look at GDI+ functioanlity, I need to have a version 1 of this project done ASAP and since I am working with Twain controls that easily set it up as bmp and TIFF, i will use bmp for display and tiff for the actual purpose that will come later. After displaying the first scanned image I will clear the buffer off the bmp file so it will not take up too much space either.

Another thing I am leaning towards is buying a ActiveX control that will allow me to display and print tiff files, there are a few in-expensive ones out there. In summary, I need this ASAP that is why I have decided to go with a non-GDI+ route. Thanks for your help strongm.

Hi muthuivs,

I'm attempting to do this myself with bmp and jgp images.

I tried looking at references and adding a reference for MSPAINT but didn't see anything.

Did you have any luck?

You know, if you'd investigated my GDI+ suggestion and done a keyword search on it you'd have found that I also reference Microsoft's little advertised Windows Image Acquisition Library for XP (which leverages GDI+ features), the latest version of which is available here:

http://www.microsoft.com/downloads/...7a-01b8-4de6-91c2-b7ea32537e29&DisplayLang=en

Once you've got that then loading and displaying a tif (or a jpg or a png) becomes as easy as setting a reference to the library, and then some pretry simple code such as:

[blue]    Dim myImg As ImageFile
    Set myImg = New ImageFile
    myImg.LoadFile "c:\demo.tif"
    Set Picture1.Picture = myImg.FileData.Picture[/blue]

Hi AccessGuruCarl,

What I did was buy a twain contro lfrom the web that supports multipage tiff's and used the pic box to display the picture. The Twain control was only about $100 bucks (I didn't want to program a huge program since I was short for time). It worked well.

Strongm,

Will the Windows Image Acquisition Library allow you to save a file in the other formats? TIFF, JPEG?

Multipage tif would be something like as follows:

[[blue]Dim myImg As ImageFile
    Dim lp As Long
    
    Set myImg = New ImageFile
    myImg.LoadFile "c:\sample.tif"
    For lp = 1 To myImg.FrameCount
        myImg.ActiveFrame = lp
        Set Picture1.Picture = myImg.ARGBData.Picture(myImg.Width, myImg.Height)
    Next[/blue][

Kodr, yes

Ypu can even do things like taking three bmp files and saving them as a single, multipage tiff
