Hi all,

I noticed that JPegForLazarus has been replaced with ImagesForLazarus.

I'm trying to install powerpdf into my ide and I have:

1. Installed ImagesForLazarus.
2. Removed required of JpegForLazarus from the powerpdf package.
3. Added ImagesForLazarus as a requirement to powerpdf package.
4. Attempt to compile powerpdf package.

However, lazarus still complains that it cannot find LazJPEG which I can see is included in the ImageForLazarus package.

Any advice?

Thanks,

No, JpegForLazarus has been merged into the LCL. So just can remove that requirement.

Hi,

Replace "LazJPEG" with "FPReadJpeg, FPWriteJpeg" in the uses section.

Thanks Vincent. I did remove the requirement and LCL was already a requirement, but still complains that LazJpeg cannot be found. Any idea what might cause that?

Below is the uses from power pdf PdfJpegImage.pas unit where the error surfaces.

uses
   SysUtils, Classes, Graphics, PdfTypes, PdfDoc, PdfImages,
   {$IFDEF LAZ_POWERPDF}
   LazJPEG // <== Here it says cannot find.
   {$ELSE}
   JPEG
   {$ENDIF}
   ;

Just for fun, I implicitly added the LazJpeg.pas file to the package and it still does not compile.

Odd.

Worked like a champ.

Thanks Leslie.

When I installed PowerPDF it did not compile without these units (maybe FPReadJpeg would have been enough though). After reading Vincent's mail tried to compile without them and it was OK. I am using the latest SVN revision now, maybe that is the the difference, but this is just a guess.

Weird. I just tried the same thing and it worked as well.

I'm sure I did something wrong there, but for the life of me, I can't figure out what it was. Maybe after removing the reference to LazJPeg, I got an error because of comma before the IFDEF'd portion and mistook it for the same error...

Anyhow, I am happy again. It works.

Now to start figuring out how it to use it :)

Maybe just remove the LazJPEG from the uses clause, it is all in Graphics now.

BTW: if you have a package that compiles, can you create a new release for Lazarus-CCR?

Vincent

I think it was very likely the same story with me. :)

I have not played much with PowerPdf yet, but after a few tests it seems that it does the job well.
Though it must have some srange bugs yet. After placing ( ... or was it deleting ?) one of the Powerpdf components on the form Windows XP seemed to be frosen. In fact it was not, but it took minutes for the OS to react for a single mouseclick and never recovered without a reboot.

Anyhow, it is nice to have the Lazarus port of PowerPdf. :)

Package for powerpdf? Sure, be glad to. Where should I send it?

BTW, I know this sound dumb, but what is Lazarus-CCR? I've seen it around have never connected the dots for what CCR stands for.

Oh, rock on. Do I need an account or should I just upload the package to my website and provide a link?

http://lazarus-ccr.sourceforge.net/#Adding_to_the_Lazarus_Code_and_Component answers your query.

It does. Thanks

I assumed you downloaded it from http://wiki.lazarus.freepascal.org/PowerPDF which links to the lazarus-ccr sourceforge site for the downloads.

I think http://wiki.lazarus.freepascal.org/PowerPDF needs updating and a new source zip for PowedPDF would be nice.

You can email the new source archive to me or provide a link and I will put them on the lazarus-ccr sourceforge site.

For new components, see

Just sent the zip file to you in a private email with the file as attachment.

I have also placed a copy at the site below which you can download.
