Hi,

We use GM 4.5 and a BitmapViewer control so we can see mutipage tiff files. Lets say we load a multipage tiff file with 10 pages and we see the 3rd page.

How can i know that i see the 3rd page?

Is there any way that tells me which page i am viewing at moment?

Hi,

Hm... The BitmapViewer control itself always works with a single instance of Aurigma.GraphicsMill.Bitmap class - it knows nothing about the source of the image.

So you should implement this by yourself. Just save somewhere the number of the currently loaded TIFF frame and use it when necessary.

Hm, i see.

Use .Tag again.

Anyway thanks, i was just thinking that having a property to store the current page number would be a good idea.

Hi,

Why ".Tag"? I think it is not the only way in your case. You may just use some class variable for that.

We have no such property because BitmapViewer is a really some sort of "universal soldier". This control is used in multiple scenarios and far not all of them include handling multipage formats.

Well,

in our scenario it is more complicated, so we use .Tag, we have to store many things for every one thumbnail in memory.

But it would be a nice idea to have a property for this reason, so multipage formats can have its property > =1 and all other formats could be by default =1.
