SQL Server, I'm reasonably sure, does not. OTOH, the (non-DB) TImage can support JPEGs if you add JPEG to the uses clause of the form containing it. -Craig -- Craig Stuntz [TeamB] .

The only format that SQL can support and save it into Image field type is BMP one, so I have to just save BMP format or convert other formates into bmp and then try to save them, and as you know I have to save large amount of data instead of it's JPG format or any other better formats... do you have any suggestion about saving them into sql 2k?! Thank you for your attention :) "Brian Bushay TeamB" <BBushay (AT) Nmpls (DOT) com> wrote Quote: Hi, I Want To save a JPG file format intor SQL 2K DB, but it seams that SQL can only support bitmap formats, do you have any suggestion or guideline?! You can store any binary data in a blob field TdbImage only supports bitmap images. If you want to display a jpeg from and SQL database you will need to use a Timage and load it with code. here is some sample code to load A timage in the AfterScroll event procedure TForm1.Table1AfterScroll(DataSet: TDataSet); var MS: TMemoryStream; J1: TJPEGImage; begin J1 := TJPEGImage.Create; MS := TMemoryStream.Create; try TBlobField(DataSet.Fieldbyname('myBlob')).SaveToStream(MS); MS.Seek(0,soFromBeginning); with J1 do begin PixelFormat := jf24Bit; Scale := jsFullSize; Grayscale := False; Performance := jpBestQuality; ProgressiveDisplay := True; ProgressiveEncoding := True; LoadFromStream(MS); end; if MS.Size >0 then Image1.Picture.Assign(J1) else Image1.Picture.Assign(nil); finally J1.Free; MS.Free; end; end; -- Brian Bushay (TeamB) [email]Bbushay (AT) NMPLS (DOT) com[/email] Back to top Craig Stuntz [TeamB] Guest Posted: Wed Jul 28, 2004 12:40 pm    Post subject: Re: Save JPG format in SQL 2K Paul Q wrote: Quote: What routine do you use to stuff it into that field? Essentially the opposite of the one he posted. Save from the TImage or TJPEGImage* to the BlobField instead of vice/versa, along with the usual calls to Edit/Post. * TImage is a GUI control which displays an image. TJPEGImage is a non-GUI control which knows how to read JPEG data. You can use TJPEGImage if you don't need a GUI display, or TImage (adding JPEG to the uses clause of the containing form) if you do need a display. Either one works. -Craig -- Craig Stuntz [TeamB] .
