hello,

i use ImageEnVect for show a plan from a building
it is 300 dpi and 1000mm x 840mm ( DIN A0 )

is's a PDF render to PSD

but the resolution it is not clear, better is a rendering
450 dpi or higher.

but the filesize is by 450 dpi to big for the commponent ( Delphi 2007 32bit )

a other solution is http://www.wpcubed.com/pdf/ but i can not realtime zoom
it's a delay from 1-2 seconds ( not so good.... )

1. it's better when i compile witch Delphi 2010 64 bit ( comming soon )
2. it's whitch wpcubed realtime zoom posible

sorry for my realy bad english

Hi Peter

So the image is around 18,000 x 15,000 pixels. That is a lot of pixels to hold in memory at once

What are your settings for:

Try using ieFile.

rfNone would be fastest for large images

Hello,
thanks for your answer.

i load the big file as background

<code>
// load the background bitmap ( PSD is very fast )
ImageEnVect1.IO.LoadFromFile(var_pfad_zur_zeichnung);

how and where i use the "Location"

i can not find a sample...


the zoomfilter / rfNone i have checked, rfNone is realy faster


thanks

Hi Peter

Please try:

// Optimize TImageEnView to handle very large images
ImageEnView1.LegacyBitmap := False;
ImageEnView1.IEBitmap.Location := ieFile;

Hello,

Thank you now it's realy faster and a can load Pictures with 100MB and more

another question:

1. it is possible to load 2 Pictures as background ( Picture left and Picture right )
Tiling or puzzles?

2. it is possible to move a Background?
i draw my Annotation over the background, the problem is when i change the background
and the background ist smaler or greater
the Annotation now not more on the same position


thanks

Peter

This is not possible, but you can load images into a layer and position the layers to the correct size and position to achieve the same affect
 
Tiling or puzzles?

Try using layers.
 

2. it is possible to move a Background?

No not possible.

Hi

Please take a look at the demo:

/Other/CellsAndGrid/CellsAndGrid.dpr

To move the background you need to set:

ImageEnView1.Layers[0].Selectable := True;
ImageEnView1.Layers[0].Locked := False;
