TIF to PDF Conversion - Convert TIF to PDF file (tif2pdf, tiftopdf)

TIF could be the format of choice for archiving important images. TIF may possibly be the top industrial and expert image standard. TIF is easily essentially the most universal and many broadly supported format across all platforms, Mac, Residence windows, Unix. Information as much as 48 bits is supported.

TIF supports most shade spaces, RGB, CMYK, YCbCr, and so on. TIF is genuinely a versatile format with a lot of options. The data is made up of tags to declare which kind of information follows. New varieties are easy to invent, which flexibility could cause incompatibly, but about any system anyplace will handle the standard TIF types that folks might encounter. TIF can store information with bytes possibly in Mac or PC system (Apple or Motorola CPU chips differ in by performing this). This choice enhances effectiveness, but all significant applications nowadays can see TIF in possibly case, and TIF files could be exchanged without any problem.

Many compression formats are utilized with TIF. TIF with G3 compression may be the universal regular for fax and multi-page line artwork documents.

TIF image files optionally use LZW lossless compression. Lossless means there's no quality loss due to the fact of compression. Lossless guarantees which you could usually read back exactly that which you believed held on, bit-for-bit identical, without information corruption. This can be a essential factor for archiving master copies of essential pictures. Most image compression formats are lossless, with Digital and Kodak PhotoCD PCD files being the main exceptions.

Compression features by recognizing repeated identical strings inside the data, and changing the numerous instances with one instance, in approaches that permits unambiguous decoding with out reduction. This actually is relatively intensive function, after which any compression approach tends to make files reduced so that you can save or open.

LZW is perfect when blending reliable indexed colours (graphics), and it is less efficient for 24 bit steady photograph pictures. Featureless locations compress much better than detailed regions. LZW works far better for grayscale images than coloration. It's regularly hardly successful whatsoever for 48 bit pictures (VueScan 48 bit TIF LZW is definitely an exception for this, making use of an effective information type that does not others use ).

TIF to PDF Converter SDK does support TWAIN function, TIF to PDF Converter SDK is very easy to use. The simplest implementation is to scan a single image using the device's user interface,

Dim new_image as imgdes ' Image descriptor
Dim rcode as long ' Return code

rcode = TWscanimage(hWnd, new_image)

And to save the image in a TIF file . . .

rcode = savetif("newimage.tif", new_image, 0)

In addition to being easy, the TWAIN device of TIF to PDF Converter SDK is powerful. You can hide the user interface, control the scan conditions, and capture multiple images.

After you get the TIF image files, you can use following VB.NET code to convert these TIF files to PDF files,

Public Function AddImage(ByRef pdfObject As Object, ByVal FileID As Long, ByVal Image As String)
    Dim code
    Dim width
    Dim height
    Dim xdpi
    Dim ydpi
    'ImageName = pdfFilePath + Image
    ImageName = Image
    bresult = pdfObject.com_VerySetFunction(FileID, Very_Set_PreProcessImage, 1, 0, 0, 0)
    'get width height
    code = 202
    width = pdfObject.com_VeryGetFunction(FileID, code, 0, 0, ImageName, 0)
    'Response.Write "width:" & width & "</br>"
    code = 203
    height = pdfObject.com_VeryGetFunction(FileID, code, 0, 0, ImageName, 0)
    'Response.Write "height:" & height & "</br>"
    'get dpi
    code = 204
    xdpi = pdfObject.com_VeryGetFunction(FileID, code, 0, 0, ImageName, 0)
    'Response.Write "xdpi:" & xdpi & "</br>"
    code = 205
    ydpi = pdfObject.com_VeryGetFunction(FileID, code, 0, 0, ImageName, 0)
    'Response.Write "ydpi:" & ydpi & "</br>"
    If xdpi > 0 And ydpi > 0 Then
        width = (width * (58 / xdpi))
        height = (height * (58 / ydpi))
    Else
        width = (width * (62 / xdpi))
        height = (height * (62 / ydpi))
    End If

    Dim startx
    Dim starty
    startx = (612 / 2) - (width / 2)
    ' bresult = pdfObject.com_VerySetFunction(FileID, 104, 20, 110, CStr(width), CStr(height))
    starty = (792 / 2) - (height / 2)
    bresult = pdfObject.com_VerySetFunction(FileID, 104, startx, starty, CStr(width), CStr(height))
    'add image one
    bresult = pdfObject.com_VeryAddImage(FileID, ImageName)
End Function

Private Sub Command1_Click()
    Dim pdfObj As Object
    Set pdfObj = CreateObject("pdfshell.shellexe")
    'Create a PDF file
    id = pdfObj.com_VeryCreate(App.Path & "\image2pdf.pdf")
    AddImage pdfObj, id, App.Path & "\001.tif"
    AddImage pdfObj, id, App.Path & "\002.tif"
    AddImage pdfObj, id, App.Path & "\003.tif"
    AddImage pdfObj, id, App.Path & "\004.tif"
    AddImage pdfObj, id, App.Path & "\005.tif"
    AddImage pdfObj, id, App.Path & "\006.tif"
    pdfObj.com_VeryClose (id)
End Sub
