Hello

I have a lot of jpg and tiff-files, which were produced by using a camera to photograph old books, which cannot be scanned. Both formats seem to have an error. The images have 3456x5184 pixel and they report to have a size of 121x183cm with a dpi of 72. But the books photographed are about A4-Format, that means 21 cm x 29,7 cm.

So how could this error be corrected by using ImageEn?

Any help appreciated!

Sincerely
Peter

Hi Peter

You can just set the dpi of the image, e.g.

ImageEnView1.IO.Params.DpiX := 200;
ImageEnView1.IO.Params.DpiY := 200;

If you use a value of around 420, that gives you A4 size output (though obviously you should write a routine to get the specific values for your images).
