Raster images look unclear in

View Designer

Raster images, such as .bmp, .tif, .jpg, or .png files, are comprised of a grid of pixels, or a bitmap. Scaling elements in

to match the DPI of the HMI device so that fonts look correct on the HMI device can make raster images look unclear in

. This happens when the DPI of the target HMI device is much larger than the DPI under which

View Designer

is running.

The unclear or pixelated effect occurs because the size of all of the elements on the screen are reduced to match the fewer number of pixels used to display fonts on

. The image may look unclear in

, but it displays correctly on the target HMI device. You can typically scale down raster graphics with little loss of quality.

Copying and pasting an image between

projects for different size HMI devices maintains the physical size of the image. The image no longer has the same number of pixels on the new HMI device as it had on the original HMI device. Add the image to the new screen or manually resize the image to correct the size on the new HMI device.
