Converting ICO to multipage TIF or PDF without OCR Issue

[dreynolds]

I was testing various conversions with my GdPicture.NET Ultimate SDK, and I discovered that there are some issues converting .ICO files:

1) No pages are available if you try to convert .ICO to multipage TIFF using TiffCreateMultiPageFromGdPictureImage, TiffSaveMultiPageToFile, and TiffAppendPageFromGdPictureImage methods. (Other image types like JPG seem to work fine.)

2) Very odd sized empty pages are created if you try to convert .ICO to multipage PDF using non-OCR PDF methods. (PDF OCR methods work fine.)

Converting these same .ICO files to JPG, PNG, WMF, etc work fine.

----

Is there an estimated release date for the next version? I'm anxiously awaiting the fixes for the bugs we discussed in my last three topic posts.

Good and bad news with GdPicture version 6.5.0...

Converting ICO to multipage TIF now works correctly!

Converting ICO to PDF or PDFA without OCR still does not work.

Hi,

Converting ICO to PDF or PDFA without OCR still does not work.

It is working for me. Please, give me a code snippet to reproduce your problem and attach the image you are trying to convert.

With best regards,

Loïc

As I said before, adding any other image type to a PDF using the exact same code below works fine.
Also using the PDF OCR methods to add these same icons will work fine.
(Adding these icons to a multipage TIF works now in 6.5.0.)
This leads me to believe it is a problem with the methods, not the files or code.

Attached are two sample icons I was using to test.

The VB.NET code basically looks like this (very simplified):

Code: Select all

'create pdf output (no ocr)
intGdPicImgOutputID= gdPicImg.PdfNewPdf("C:\output\IconTest.pdf",  false, "Title", "Author", "Subject", "" , "" )
gdPicImg.PdfSetCompressionForColorImage(intGdPicImgOutputID,PdfCompression.PdfCompressionNone)

'get and add ico #1
intGdPicImgInputID1 = gdPicImg.CreateGdPictureImageFromFile("c:\input\BatSymbolIcon.ico")
intPdfImageID1 = gdPicImg.PdfAddImageFromGdPictureImage(intGdPicImgOutputID, intGdPicImgInputID1)
sngPdfImageWidthIn1 = gdPicImg.GetWidthInches(intGdPicImgInputID1)
sngPdfImageHeightIn1 = gdPicImg.GetHeightInches(intGdPicImgInputID1)

'get and add ico #2
intGdPicImgInputID1 = gdPicImg.CreateGdPictureImageFromFile("c:\input\StratixIcon.ico")
intPdfImageID2 = gdPicImg.PdfAddImageFromGdPictureImage(intGdPicImgOutputID, intGdPicImgInputID2)
sngPdfImageWidthIn2 = gdPicImg.GetWidthInches(intGdPicImgInputID2)
sngPdfImageHeightIn2 = gdPicImg.GetHeightInches(intGdPicImgInputID2)

'set pdf measurement unit

Don, I'll check this issue tomorrow. We will fix your problem.

Thanks, let me know if you need anything else.

Hi Don,

Your code is wrong. If I understand, you are trying to create a multipage from 2 icons, 1 on each page.

Here a vb.net sample to do that. Let me know if you need more information.

Code: Select all

        Dim PdfID As Integer = Imaging1.PdfNewPdf("c:\test.pdf")
        Dim ImageWidth, ImageHeight As Single

        Imaging1.PdfAddImageFromFile(PdfID, "c:\BatSymbolIcon.ico") 'Image 1
        Imaging1.PdfAddImageFromFile(PdfID, "c:\StratixIcon.ico") ' Image 2

        'Drawing first image
        ImageWidth = Imaging1.PdfGetImageWidth(PdfID, 1)
        ImageHeight = Imaging1.PdfGetImageHeight(PdfID, 1)
        Imaging1.PdfNewPage(PdfID, ImageWidth, ImageHeight)
        Imaging1.PdfDrawImage(PdfID, 1, 0, 0, ImageWidth, ImageHeight)

        'Drawing second image
        ImageWidth = Imaging1.PdfGetImageWidth(PdfID, 2)
        ImageHeight = Imaging1.PdfGetImageHeight(PdfID, 2)
        Imaging1.PdfNewPage(PdfID, ImageWidth, ImageHeight)
        Imaging1.PdfDrawImage(PdfID, 2, 0, 0, ImageWidth, ImageHeight)

        Imaging1.PdfEndPdf(PdfID)

Kind regards,

Loïc

The only major difference I see is that you hardcoded the values 1 and 2 in the PdfDrawImage() methods where I used the returned IDs from the PdfAddImageFromGdPictureImage() methods.

I don't think you can count on those values always being 1 and 2. The documentation says that you should use "value returned by the PdfAddImageFromFile or the PdfAddImageFromGdPictureImage function", which is exactly what I did.

The other differences are different ways to do the same thing. You used PdfAddImageFromFile(), I used CreateGdPictureImageFromFile() + PdfAddImageFromGdPictureImage(). You got your width and height after adding the image to the PDF, I got width and height from the original image.

Note: This is only a problem with ICO files and the PDF non-OCR methods.

If you add a 3rd image and it is any other image type, it will show up in the PDF fine along with the two bad pages from the ICO files... using the exact same code.

Using the PDF OCR methods, ICO files can be added to PDF without issues.

[dreynolds]

Here is a screenshot of what the PDF output looks like.

I am using the code I sent you earlier for the PDF on the right.
I'm using almost the same code with the PDF OCR methods for the PDF on the left.
I added the two .ICO files that I attached, then a 2 page TIF, then a JPG to the PDF output.

Notice the PDF OCR methods produce a good PDF with the icons visible on the left side.
The PDF non-OCR methods produce a good PDF, but the icon pages are blank with weird sizes and the other image pages look fine.

Don,

From your code:

Code: Select all

intPdfImageID2 = gdPicImg.PdfAddImageFromGdPictureImage(intGdPicImgOutputID, intGdPicImgInputID2)

What is intGdPicImgInputID2 ??

I don't think you can count on those values always being 1 and 2

You can. Don't make confusion between a GdPicture image and a number of an image embedded in a PDF.

Code: Select all

gdPicImg.ReleaseGdPictureImage(intPdfImageID1)
gdPicImg.ReleaseGdPictureImage(intPdfImageID2)

intPdfImageID1 & intPdfImageID2 are no GdPicture image. You don't have to release they.



here your code with some basic corrections:

Code: Select all

   Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim gdPicImg As New GdPictureImaging
        Dim PdfID As Integer
        Dim intGdPicImgInputID1, intGdPicImgInputID2 As Integer
        Dim intPdfImageID1, intPdfImageID2 As Integer
        Dim sngPdfImageWidthIn1, sngPdfImageHeightIn1, sngPdfImageWidthIn2, sngPdfImageHeightIn2 As Double

        'create pdf output (no ocr)
        PdfID = gdPicImg.PdfNewPdf("C:\IconTest.pdf", False, "Title", "Author", "Subject", "", "")
        gdPicImg.PdfSetCompressionForColorImage(PdfID, PdfCompression.PdfCompressionNone)

        'get and add ico #1
        intGdPicImgInputID1 = gdPicImg.CreateGdPictureImageFromFile("c:\BatSymbolIcon.ico")
        intPdfImageID1 = gdPicImg.PdfAddImageFromGdPictureImage(PdfID, intGdPicImgInputID1)
        sngPdfImageWidthIn1 = gdPicImg.GetWidthInches(intGdPicImgInputID1)
        sngPdfImageHeightIn1 = gdPicImg.GetHeightInches(intGdPicImgInputID1)

        'get and add ico #2
        intGdPicImgInputID2 = gdPicImg.CreateGdPictureImageFromFile("c:\StratixIcon.ico")
        intPdfImageID2 = gdPicImg.PdfAddImageFromGdPictureImage(PdfID, intGdPicImgInputID2)
        sngPdfImageWidthIn2 = gdPicImg.GetWidthInches(intGdPicImgInputID2)
        sngPdfImageHeightIn2 = gdPicImg.GetHeightInches(intGdPicImgInputID2)

        'set pdf measurement unit
        gdPicImg.PdfSetMeasurementUnit(PdfMeasurementUnit.PdfMeasurementUnitInch)


        'add ico #1 page and draw image
        gdPicImg.PdfNewPage(PdfID, CSng(sngPdfImageWidthIn1), CSng(sngPdfImageHeightIn1))
        gdPicImg.PdfDrawImage(PdfID, intPdfImageID1, 0, 0, CSng(sngPdfImageWidthIn1), CSng(sngPdfImageHeightIn1))

        'add ico #2 page and draw image
        gdPicImg.PdfNewPage(PdfID, CSng(sngPdfImageWidthIn2), CSng(sngPdfImageHeightIn2))
        gdPicImg.PdfDrawImage(PdfID, intPdfImageID2, 0, 0, CSng(sngPdfImageWidthIn2), CSng(sngPdfImageHeightIn2))

        'end pdf output
        gdPicImg.PdfEndPdf(PdfID)

        'cleanup
        gdPicImg.ReleaseGdPictureImage(intGdPicImgInputID1)
        gdPicImg.ReleaseGdPictureImage(intGdPicImgInputID2)
    End Sub

Also, you should add this in your source code:

Code: Select all

Option Strict On
Option Explicit On

Hope this helps,

Loïc

I just tried the same test with 4 microsoft icon files, just to make sure it isn't my icons that are causing the issue.

The same problem occurs with the microsoft icons.

This is pretty conclusive that the problem is somewhere in the GdPicture.NET PDF non-OCR methods when using ICO input files.

Let me know if you want me to try anything else.

[Loïc]

Don,

Please consider my previous answer: viewtopic.php?t=2092#p7038

There in not any problem in GdPicture.NET, no problem with your file, only problem with your code...


Cheers,

Loïc

[dreynolds]

Sorry, I just saw your previous posts. The code I posted is not the actual code. The actual code is much more complex, and I definitely declare all variables and use option explicit, etc. Broken down and simplified for this problem, those are the methods being used.

If the values returned by PdfAddImageFromGdPictureImage() are not ImageIDs, then my only mistake is trying to release them later. I don't think it would really matter since the release doesn't cause an error and it happens after the PDF is done being created.

Again, this code works for any other type of file EXCEPT ICO files. It works for JPG, BMP, WMF, PNG, multipage TIF, multiframe GIF, etc. It will even add those other types to the same PDF fine and only the ICO pages will have issues.

The code I posted is not the actual code

OK... What is the actual code ??

[dreynolds]

I tried your code and it does work. There must be a mistake somewhere. I noticed that the heights I am getting from the icons are all 0. I will review all my code thoroughly. Thank you for your help. I'll post if I figure it out.
