What's New in 4.1.2?
New Features
- now it is possible to align the image at top-left, top-center, top-right, center-left, center-center, center-right, bottom-left, bottom-center and bottom-right
- now it is possible to create and define an angle object in code
- now selected layer box and grips are displayed over all layers
- now a box is displayed when rotating a layer
- TIEBitmap: now it is possible to apply a zoom filter when PixelFormat=ieVirtual
- now it is possible to specify number of strips in a TIFF file
- DICOM: enhanced support for lossless-jpeg compression
- Now it is possible to remove last inserted selection point (when MouseInteract = [miSelectPolygon])
- Added: Const array of languages available for IEVision OCR
- now it is possible to rotate layer 0 using MouseInteract=[miRotateLayers]
- TImageEnMView: now SaveSnapshot saves also ImageTag property
- now it is possible to draw vectorial objects over Black/white images (without RGB conversion). Experimental feature.
- TIEAcquireParams.FindSourceByName to locate devices using only their name
- TIEAcquireParams.SetSourceByStr now works even if a device name is passed
- IEVision Initialize overloaded method allows passing an alternative DLL path
- TIFF: supported Deflate/ZIP with FillOrder=2 and with separated planes
- TImageEnIO.SaveToFile: now can save LYR and ALL file formats when TImageEnIO is attached to TImageEnView or TImageEnVect
Fixed Bugs
- BUGFIX: TImageEnProc.Opening, produces white border around black/white images
- BUGFIX: fixed minor bugs
- BUGFIX: fixed bug that sometimes writes wrong pixels in the right-side of last line when compressing TIFF with ioTIFF_G3FAX1D
- BUGFIX: fixed bug that sometimes writes wrong pixels in the right-side of last line when compressing TIFF with ioTIFF_CCITT1D and TIFF_FillOrder=2
- BUGFIX: writing BMP when PixelFormat=ie8g and NativePixelFormat=true
- BUGFIX: reading gray scale, tiled, JPEG encoded TIFF when NativePixelFormat=true
- BUGFIX: TIEDirectShow.EndOfStream now works (when parent of TIEDirectShow is TImageEnView.IO)
- BUGFIX: TImageEnIO.LoadFromStream doesn't set Aborting=true when file content type is not detected
- BUGFIX: incorrect matching of Twain devices name
- BUGFIX: wrong image display when Operation<>ielNormal on the first layer and Zoom > 100
- BUGFIX: TImageEnMIO print preview dialog, now centimeters label is displayed correctly
- BUGFIX: duplex in WIA doesn't work
- BUGFIX: now Opening/Closing/Maximum/Minimum for B/W images works correctly
- BUGFIX: fixed DICOM gray scal pixel ranging problem
- BUGFIX: PSD, enhanced reliability on corrupted files
- BugFix: May get A/V error when accessing AcquireParams properties if source has not been set
- BugFix: Transition may not occur in correct direction
- BUGFIX: reading G4FAX with PhotometricInterpretation=BLACKISZERO has inverted colors
- BUGFIX: fixed bug in Layer.Operation=ielLuminosity
- Fixed: TIEAquireParams.SetSource may not work if Unicode string is passed as Location parameter
Changes
- TImageEnView: added ImageHorizAlignment property
- TImageEnView: added ImageVertAlignment property
- TImageEnMView: added SetThumbnailSize method
- TIEAnimation: added BorderPen property
- TImageEnVect: added SetObjAnglePoints method
- TImageEnVect: added ObjAnglePoints property
- TIOParams: added EXIF_GPSLatitude property
- TIOParams: added EXIF_GPSLongitude property

- TImageEnVect.DrawObjectsToBitmap: added AdaptBitmapPixelFormat parameter
- TImageEnVect.DrawOneObjectToBitmap: added AdaptBitmapPixelFormat parameter

I want to retrieve all the pixels of an TImageEnView named Img in a dynamic array named v_Img.
I try to do that
Img.IO.LoadFromFile(FileOpenDlg.FileName);
Img.IEBitmap.PixelFormat:=ie8g;
v_ImgY:=Img.IEBitmap.Height;
v_ImgX:=Img.IEBitmap.Width;
v_ImgSize:=v_ImgY*v_ImgX;
SetLength(v_Img,v_ImgSize);
P:=Img.IEBitmap.GetSegment(0,0,v_ImgSize);
Move(P^,v_Img[0],v_ImgSize);
An exction is raised on the move command. Sure the Pointer returned by GetSegemnt point on a zone of bad size....
Thank for your Help
Gerard

Hi Gerard
Are you using a virtual bitmap provider (i.e. have set VirtualBitmapProvider or OnRenderVirtualPixel)? If not, you can only return the last line obtained from Scanline[].
