problem when printing

[Greenleaf]

Hello,
I'm previewing my report with CrPreview. Everything's fine. If I choose to print the preview with paper size A3 , the images are displayed fine, if I print in A4 the images are too big to fit the page. Is there a way to print the images properly according the paper size? I' d like the images to "shrink" authomatically in order to fit the page if they are too big.

Please post your software/version, and whatever development language you are using.

If you only have two choices, then render the 2 sixed graphics you need and conditionally suppress them based on the page size.

One problem when programtically resizing images is that you lose resolution, so this is a good cheat.

I use Crystal Reports XI developer edition and development language us Delphi 7

That's what I feared...

Here's a whitepaper on resizing OLE Object images using the RDC, perhaps you can use some of it in your Delphi app:

Yes, Crystal Reports can be such a pain, at least for me. But wouldn' t it be possible to be more general and not to be restricted to 2 papersize only. Here at work they have requested me not to use specific numbers. Is there a way to retrieve information from the printer? Or say, choose paper size by means of a dialog window and then have the picture resized according to the paper size?
I hate Crystal so so much... :-(

Hi,
Blaming Crystal for something no report generator ( as far as I konw) can do is a little harsh..Graphics are difficult to handle in any case, since pixel depth, display resolution , etc are very client dependent and expecting some magic process to know how to resize on demand ( while maintaining the correct aspect ratio) is, in my humble opinion, unreasonable.

Software is rarely able to overcome unrealistic constraints on good design.

yes but I saw that for vb.net there is a method for the crviewer and it is called bestfitpage but in the delphi component there is not such a method.

I'm trying this way.

printdialog1.execute;
picture.width := printer.pagewidth;

and to this point it works; if I choose different paper formats the printer.pagewidth changes but...the last line

crreport.printout(False,1,False,1,1);

ruins everything; if with printdialog I choose A3 che crreport.printout prints in A4; it completely ignores what I chose.

It's unbelivable. I downloaded and installed the horfix recommended by BusinessObjects regarding the method crreport.printout. Apparently there was a bug in that method but the hotfix doesn't work; and even the code I posted ini the previous post doesnt' work anymore. Now I have to write:

crreport.setUpPrinter(0);
picture.width := printer.pagewidth;
crreport.printout(False,1,False,1,1);

the paper size changes but now it's the picture width that doesn't change. Printer.pagewidth is always the same, no matter what I chose. How can I get out of this stuck?!? Has anybody have ever faced this problem???
