eballinas	Posted - Oct 12 2022 : 14:05:55 I have tried to modify the parameters of a TIFF image in different parts of my code. I have seen following the debugger, the param modification is done, executed. But, when I save it to a file or a database, the size is the same that the original images. What am I doing wrong?

xequte	Posted - Oct 16 2022 : 20:44:36 Please show me the code you use for adding images to the database. Nigel Xequte Software www.imageen.com
eballinas	Posted - Oct 14 2022 : 17:00:50 Can you explain me what do you mean with "Saved"? Please help me... This is very important.
xequte	Posted - Oct 14 2022 : 16:03:46 The code should be: ... fDBMultiBitmap.OnGetSaveParams := DBMultiBitmapGetSaveParams; ... procedure Tfmain.DBMultiBitmapGetSaveParams(Sender: TObject; const Filename: string; Params: TIOParams); begin // Use JPEG compression when blob is save to database (Assumes ImageFormat is ioTIFF) Params.TIFF_Compression := ioTIFF_JPEG; end; Note: The OnGetSaveParams is only called if the image needs to be "saved" to the database. If it does not need to be converted it will just be added to the database without saving. Nigel Xequte Software www.imageen.com
eballinas	Posted - Oct 14 2022 : 09:32:13 var Params: TIOParams Is there an error here?
xequte	Posted - Oct 13 2022 : 16:06:11 Hi This has been sent. Please check your Spam folder if it has not arrived. The params are not set, because they need to be specified before the image is saved to the database blob. Nigel Xequte Software www.imageen.com
eballinas	Posted - Oct 13 2022 : 11:03:51 I just send an email. But, I would like to know more about the problem. Why the params were not updating?
xequte	Posted - Oct 13 2022 : 00:21:44 Hi Please email me for an update that adds an OnGetSaveParams event, e.g. ... fDBMultiBitmap.OnGetSaveParams := DBMultiBitmapGetSaveParams; ... procedure Tfmain.DBMultiBitmapGetSaveParams(Sender: TObject; const Filename: string; Params: TIOParams); begin // Use JPEG compression when blob is save to database (Assumes ImageFormat is ioTIFF) Params.TIFF_Compression := ioTIFF_JPEG; end; Nigel Xequte Software www.imageen.com
