In the end I think I have got to work:
SubReport1.Report.ColumnPositions.Clear;
SubReport1.Report.Columns := 5;
SubReport1.Report.ColumnWidth := 20;
I think there is a problem if the Columns in the pagesetup … -
Using the columnpositions method and all column widths are the same, what happens if the positions are not equally spaced, what is the/ column width? Can I set the width of the set of columns
During setup I set the borders visible so I ca… -
Hi there, thankyou.
But, I still can't find the link -
Can you confirm how to economically process the stream? I load a Tjpeg from the database, I create a bitmap and set the width and height to small, and then stretchdraw the jpeg into the bitmap:
// expose the protected properties
But what can I do if I have large JPG's in my database and cannot compress them? I have written my own compression routine (load a Tjpeg Image and the stretchdraw it onto a small ppImage. But how can I use a ppDBImage and make it small?
This is what I did:
I set the RowsPerRecord to "n", and used a 1 row dataset pipeline.
I hooked the Band.OnBeforePrint to find TppImages and load the image when the band printed.
This would always load so I got the MD5 of the l…I think I have resolved the problem. It was that when I created the report from Delphi the parent "owner" was not set correctly. I will check that, difficult to explain, so may I say: resolved, *not a bug* !Apologies for the bug comment
Its just took me a time to work out what was happening. Its just that in my program…I got all that to work, but when I reload the template I get an error saying already exists raProgramModule1
Why is this not cleared when the oReport.Template.LoadFromFile?
I have not loaded the data or created pipelines at this stag…I got it it to work. Thanks.
Even though I hook the OnBeforePrint in my delphi app, I can still hook it in RAP. I can then pick up the BandsPerRecord from my datasets and then I get the right repeats.
Does that seem reasonable?…Thank you! I will try that in RAP or design.
In my delphi code I use the onbefore print to set the image borders for debug. (maybe I could use another event) This seems to override the RAP onbeforeprint. How can I get the RAP one to fire as we…The datasets are all set up with their events all working. Then the pipelines are connectedf.
Any data change for any reason (and movements from reportbuilder) will ripple down, opening and closing the datasets. Reportbulder will then wor…I will try that. But does the size of the JPG in the database make a difference? The only way I can shrink them is at run time and use a normal ppImage. I thought that the image was simply written to the image "canvas" which is small. Can I set the …plain image
