i am using vista with dpi scaling set to 144%. the primoPDF "create PDF" box is not dpi aware and has a very awkward layout (i'd post an image but cant figure out how). any plans to fix this?

* As this earlier post describes, the client area of the window is just a bitmap. Because of the way the DWM works and how it sits atop WPF technology and thus atop DirectX, scaling the client area is really just a matter of modifying a scale transform on the appropriate node of the "visual tree" that describes the desktop. This notion was described here.
* When that transform scaling is performed on the visual tree, ultimately in DirectX, this results in performing a texturing operation with the same sized texture but a larger mesh (the target client area), resulting in stretching the client area bitmap.
* The Non-Client Area (the window frame) is not scaled uniformly with the client area. As in non-DPI scaled situations, it's "painted" separately. It's not simply subjected to bitmap scaling because for the frame, we can natively scale it, and choose elements appropriate for the target resolution, render caption text appropriate for the target resolution, etc.
* While one can imagine any scale factor coming about as a function of the target DPI resulting in windows that land off of pixel boundaries and represent fractional pixel contribution. However, we avoid this and clamp our scaling so that we always remain on pixel boundaries and remain as crisp as possible, within the confines of the graphical filtering algorithm in place.

As user above has posted. However, this is not going to increase the quality of the image. All changing the DPI does is increase the dots per inch but it has to work within we can bring you wholesale prices on Isuzu Power Steering Rack (http://www.powersteeringpros.com/Isuzu_Power_Steering_Rack.htm) through our national chain of warehouses the confines of the pixel dimensions. Adding DPI will add pixels which stretches the current pixel data and will become more "pixelated".Get the AC parts like AC Compressor, AC Condenser, AC Evaporator and more parts ...
