Property Value

A value that controls the resizing raster image befor converting it to WriteableBitmap.

The defualt value is 1.0, which means no resizing.

Remarks

-Wpf has some restriction for large WriteableBitmap so when converting raster image to the WriteableBitmap which cause some memory issues. We added this property to resize the raster image before converting it to WriteableBitmap. The image quality will decrease but we will improve the memory consumbtion for WriteableBitmap.

-You have to use suitable ratio to balance between image quality and the memory usage for image (WriteableBitmap), being viewed.

-The default value is 1.0 which means no resizing, 0.5 means resize to the half.

-The values range should be from 0 to 1.0.

-You have to set this value before setting viewer image to take effect.
