Is it possible to print color annotations without converting image to color?
Black-and-white image has big size after converting into color and out of memory messages appear. |

Sorry, can you confirm what code you are using?
Also, if you are getting an out of memory error, please show us how to reproduce that too (and ensure LegacyBitmap = False).

I use
IO->Params->ImagingAnnot
to add objects.
IO->PrintImage
to print
LegacyBitmap = False
Image size is 10000x13000 px |

This is resolved for 8.0.1. You can email me for updated source code earlier if you like.

I see the same error in the latest version.
I have black-and-white image and color annotations (IO->Params->ImagingAnnot).
ImageEnVect1->IO->PrintImage
See "OutOfmemory" error
I can send test file

But if I use before printing:
ImageEnProc->ConvertTo24Bit();
ImafeEnvect1->CopyObjectsToBack(ObjAntialiasing, true);
it works without error messages |

Hi
I'm afraid I cannot reproduce that.
I have loaded the image as follows:
ImageEnVect1.IO.LoadFromFile('d:\D-10-4010-11.tif');
ImageEnVect1.IO.Params.ImagingAnnot.CopyToTImageEnVect();
And printed the following ways:
Printer.BeginDoc;
ImageEnVect1.IO.PrintImage();
Printer.EndDoc;
Printer.BeginDoc;
ImageEnVect1.IO.PrintImage(Printer.Canvas, 0, 0, 0, 0, ievpCenter, iehpCenter, iesFitToPage, 0, 0, 1, True);
Printer.EndDoc;
ImageEnVect1.IO.DoPrintPreviewDialog( iedtDialog, '', True );
All print as expected.

I see error message.
Why there is no message if I combine annotations before?
ps
What are settings of you printer?
I need to print in color and resolution 600 dpi. |

I created the empty project and again see this error message (Out of memory).
void __fastcall TForm9::btnOpenClick(TObject *Sender)
{
ImageEnVect1->IO->Params->ImageIndex = 0;
ImageEnVect1->IO->LoadFromFile("C:\\TEMP1\\D-10-4010-11.tif");
if (ImageEnVect1->IO->Params->ImagingAnnot->ObjectsCount != 0)
ImageEnVect1->IO->Params->ImagingAnnot->CopyToTImageEnVect(ImageEnVect1);
}
//---------------------------------------------------------------------------
void __fastcall TForm9::btnPrintClick(TObject *Sender)
{
TPrinter *MyPrinter;
MyPrinter = Printer();
MyPrinter->BeginDoc();
ImageEnVect1->IO->PrintImage(MyPrinter->Canvas, 0, 0, 0, 0, ievpCenter ,
iehpCenter, iesFitToPage, 0, 0,
1, true, false, "", 5, clBlack);
MyPrinter->EndDoc();
}
//--------------------------------------------------------------------------- |

Hi
Your example code works fine here. I am printing at 600dpi and full color to an HP LaserJet.
So I presume you don't get an error when you set the PrintAnnotations parameter to false?

I don't see error message if I combine annotations with background and use print again.
ImageEnProc->ConvertTo24Bit();
ImafeEnvect1->CopyObjectsToBack(ObjAntialiasing, true);
and PRINT with the same parameters
it works without error messages
ps
I tested on Windows 7 (32 bit)
and
Windows 10 (64 bit) |

There are no annotations after combining.
I delete them. |

Hi
I mean when you use your example code above. I presume it works without error when you change to
ImageEnVect1->IO->PrintImage(MyPrinter->Canvas, 0, 0, 0, 0, ievpCenter ,
iehpCenter, iesFitToPage, 0, 0,
1, FALSE, false, "", 5, clBlack);
Maybe you can create a temporary bitmap using DrawObjectsToBitmap and print that instead.

What is the difference of printing color bitmap with a size of 10,000x10,000 pixels with the option
PrintAnnotations = FALSE
and
black-and-white image with a size of 10,000x10,000 pixels with color annotations with the option
PrintAnnotations = TRUE
??? |

Look in the help file.
If true and the image contains imaging or ImageEn annotations they will be printed

In the first case, it prints the image directly.
In the second, a copy of the image is created, its pixelformat upscaled to 24bit and annotations drawn.

| Maybe in the second case the size of the canvas is larger than the original image and therefore an error appears? |

I'm trying to use
#include "iexHelperFunctions.hpp"
IEBitmap1->PrintImage(.....);
and see
[BCC32 Error]E2316 'PrintImage' is not a member of 'TIEBitmap' |
