Hi John,

I'm a little puzzled by this. With the demo program, the X and Y dpi fields are set after scanning. You may want to verify the values DPI values when running the demo program in the .OnAcquire method. It may be your scanner not returning the DPI properly back to the application.

Also, many softwares, especially with BMP and JPEG formats, don't read the resolution fields. It possible that this version of PhotoShop does not read the resolution fields, although I doubt it.

If you still have problems, you may email me a small JPG file scanned and saved with Envision. I'll double check to make sure the resolution was properly saved in the file.

Best regards,
