Can a 16 bit image be displayed in a picture control?

[Kian]

Hi,
Why doesn't the Flatten Pixmap.vi (LV 5.1) allow 16-bit pixmap input? Cos I need to display my image in a picture control. So is there a way to display a 16-bit image in a picture control without losing resolution?

Thanks.

16-bit is something alien to the PC world. On a color monitor you have red, green and blue, all encoded in 8 bits each, making it 24 bit. If you do not make use of the color but have a grey scale image, that makes all three primary colors the same value, reducing your resolution to a mere 8 bits. So you actually have no way to DISPLAY your higher resolution of 16 bits appropriately on a standard monitor.
ergo: No need to convert it.

Very strange.
16-bit images are very friendly to the PC world. Most of high resolution CCD matrix, scanners and other image input devices support 16 bit images. Such popular graphic formats as GIF, JPEG, PNG can work with 16-bit images. 16-bit images are very often used in computer games to increase the value of fps in case of not very fast video accelerators. And of cause monitors support this resolution. You can click by the right button of your mouse on the Windows desktop, select Display properties and then Settings. One of always supported Color schemes is High Color (16-bit).

No all true.
16 Bit Colors! (not grey scale) is just a reduction of hues. You will have to coose between 65536 different Colors (at a time) each of which is probably made of a byte red, green and blue each. You can even have the same coded in 8 bits. And Labview supports that as well through color lookup tables.
Just the Labview 16 Bit images (at least like I use them) are true 16 Bit grey scales, No color involved, And this is something you can't display on a monitor, maybe even the human eye could not distinguish??
16 vs. 32 Bit is a matter of your grapics interface anyway (and that's what you set with right mouse). As long as most VGA monitors are connected with analog signals, there in no such thing as a bit on the cable.
