I'm trying to use LazReport to generate reports which should show an image (the company logo) and some Chinese text.
Currently (Lazarus 1.0.4 on Linux platform) I have the following scenario:

1) Report preview is correct (Image and Chinese text properly shown)

2) Report printout shows the Image, but skips Chinese characters.

3) Pdf export shows the image, but replaces Chinese characters with question marks. I understand that PowerPdf doesn't support Unicode, but changing the font encoding from Unicode to Big5 doesn't help.

4) Html export shows the Chinese characters, but doesn't show the image.

5) Text export shows the Chinese characters, but obviously doesn't show the image.

Is there a way to get a printout which properly reproduces the Report preview?

Can someone point me in the right direction?

2) Report printout shows the Image, but skips Chinese characters.

That's correct, TPostscriptCanvas do not support all unicode, Latin and Cyrillic should be fine though.

3) Pdf export shows the image, but replaces Chinese characters with question marks. I understand that PowerPdf doesn't support Unicode, but changing the font encoding from Unicode to Big5 doesn't help.

That's correct, PowerPdf is limited to Latin scripts.

4) Html export shows the Chinese characters, but doesn't show the image.

Yes, it doesn't export images. I think an option can be added to html exporter so it can export images too.

5) Text export shows the Chinese characters, but obviously doesn't show the image.

That's correct.

There are at least two solutions, according to bug report http://bugs.freepascal.org/view.php?id=15161 using Qt interface should work. The other solution is exporting pages as images with Image Exporter, that I can confirm it does ok, see LazReport/source/addons/imgexport/lr_extexp.lpk

There is another possibility, for the future, time ago petr kristan made a CairoCanvas object that can be used instead of TPostscriptPrinterCanvas. After I fixed some things I made it work again but showing Chinese text and images was unsuccessful. It currently uses plain cairo to show text, I will try to improve it.

Forgot to say, the Image exporter has another html exporter (appear as "HTML (div-based)" on export list) that do include images and Chinese text

Thank you very much. I'll try your suggestions.

What about Arabic? Some fonts do not produce any Arabic output at all, and others produce detached characters (isolated form) only.

Pls refer to bug http://bugs.freepascal.org/view.php?id=19435 and http://forum.lazarus.freepascal.org/index.php/topic,13206.0.html for more info.

As was said many times already: do not post to an existing thread as this decreases the likelyhood that someone reads your message.

It sounds strange. If there was such bug in TLabel, it would affect all label captions and not only some of them.
Can you attach a demo application demonstrating it?

dear Mr. Manninen, thanks very much for your observation,

after my message, I have been working with the appl. and found that redefining the label control the problem was solved.

thanks again

yours
