Natmap 250K on CD

Ozi, thanks for the reply. How do I find out what video card I have? Using Win ME with 128 meg of SDRAM in a lap top. Hope you can help me.

John, what brand and model of lap top do you have?

The reason why you are having this issue with the new Natmap maps, they have taken the DPI (from memory) 150dpi to 250dpi.

Do you use OziExplorer software at all?

If you do, download the Img2OZF convertor and convert all your ECW to OZF2. This is based on PNG and only loads the screen image to memory, not the whole picture file like other formats. PNG and OZF2 page the memory that quickly, you would not know it is happening. What is more, you get 10% zoom steps. You would not (or I should say, highly unlikely) to have any issues whatsoever with OZF2 or PNG.

If you do not have OziExplorer, I don't know a program that will bulk convert from ECW to PNG.

Laptops older than say 12 months were always natorious for poor video speed and memory. However, the latest version video drivers should always make a decent improvement.

Thanks. Yes have oziexplorer software, but have not done as you suggest. I will try that, will probably get into all sorts of problems!!!! If I may, could you e-mail me direct, lornjohn@hotmail.com with instructions how to do what you suggest or is it very easy? Thanks for the info.

Hello - wouldnt bother converting ecw to ozf2 (unless you have to for CE) or to png. Ecw also only loads screen section to memory and has HEAPS smaller file. Loads fast. Can see no benifit in any other image format.
Merry Christmas

Hey Ozi, if you got a CD burner, I'll hold a backup copy of them here for you so if yours get damaged I'll have a spare set for you here :D

Thanks, will do that.

Thanks for the reply. Had to delete/uninstall old maps etc before I could load new series. So presume seeing new maps.

Thanks for that will try it and see whathappens.
