 |
|
I am trying to print an image and the printed copy is about 1 1/2 inches
square. Nothing I do seems to change this size. How can I change the
printed size? In the code below Image1 is about 950 X 950.
Graphics::TBitmap *Bitmap = new Graphics::TBitmap();
Bitmap->Assign(Image1->Picture);
Printer()->BeginDoc();
try
{
Printer()->Canvas->Draw(0, 0, Bitmap);
Printer()->EndDoc();
}
catch(const Exception &)
{
Printer()->Abort();
} |

Use StretchDraw() instead.

Be aware that many printer have issues with there drivers and
printing images. You might get away with StretchDraw on one
printer and it fails on another. That's because while most
modern drivers do indeed support Device Dependent Bitmaps,
MicroSoft does not require it for printer driver.
If you want it to print correctly across all printers, you
need to use a Device Independent Bitmap. For example:
http://groups.google.com/group/borland.public.cppbuilder.vcl.components.using/msg/d40f4280c78e39dd?hl=en&
Note that the sample will print it so that it appears the same
size as it does on screen and that it uses a pointer of type
TBitmap. If your TImage's image is indeed a bitmap, you can
use that (TImage::Bitmap). Otherwise, you'll need to convert
it. The rest you can figure out for yourself from the sample.

If your budget can afford it, I strongly recommend Joe Hechts printer dll.

Why pay for something when there is a solution that's free?

Because the free solutions have a reasonbly high failure rate in the deployed world.
Most of our customers used the free solutions, and bought our image printing product
only after finding this out out the hard way (unhappy customers, refunds, and a lot
of time trying all the free solutions).
Our TExcellentImagePrinter product is the defacto standard if you need reliable image prinitng.

That may have been true 4 or 5 years ago but no longer. Our
code prints on thousands of different printers in all kinds
of environments and not one failure has been reported.
