The UI resizing feature in IPlug2 is really nice but, as with any photo editor, bitmaps tend to get fuzzy/blurry when upscaled (but remain sharp when downscaled). Therefore, it seems it would be best to source bitmaps at the largest size and then only scale _downward_ - i.e., with a resizer range of say 30% -100% rather than 60% -200%. The default load size (“middle/default scale”) would also have to change accordingly, goal being to only resize downwards. I’ve searched through the code but I don’t see what is controlling the resizer scale factors. Is that range hard-coded/fixed - or can it be overridden? If so, how? ---

In config.h, change `#define PLUG_HOST_RESIZE 0` to `#define PLUG_HOST_RESIZE 1` ---

Just tried what you suggested but it didn’t have any effect. Same sizes and scales as when set to “0”. ---

that is unrelated. That means that the app-wrapper window is resizeable. ---

you definitely need to include high res bitmaps ---

Dragging the corner sizer still seems to range +200/-50% from size specified in #define PLUG\_WIDTH / #define PLUG\_HEIGHT ---

IGraphics::SetScaleConstraints() is the method you want to set the constraints for the scaling. As Oli mentions you need to supply high res bitmaps to avoid fuzziness - see the IPlugControls example to see examples of how to name. If you supply a x2 bitmap it should get used at a scale of 200%. ---

> [@AlexHarker](#): > > If you supply a x2 bitmap it should get used at a scale of 200%. Yes, question about @2x.png files - I understand that this will load the 2x bitmap in Retina displays - but what happens to the _position_ of those bitmaps on the plugin GUI? Do the x2 bitmaps load in their x1 positions or do their X/Y coordinates also get scaled by x2 so that everything scales up proportionately? I don’t have a Retina display so I can’t see how this works. Any way to test it on an HD display? ---

Everything is scaled correctly - you specify things in IGraphics pixels, which are then scaled to the display size. ---

Oh, I see. So that’s why we should use “const IRECT& bounds” rather than the “float x, float y” overload of IBKnobControl, for example? “Bounds” is dynamic whereas “X/Y” is static? I am working to bring all of my plugins over from iPlug1 - which uses the “float x, float y” approach. In iPlug2 everything scales up/down properly but, as you might expect, the graphics get blurry at max scale (200%). So does the “const IRECT& bounds” approach with additional @2x bitmaps keep it sharp(er) throughout - or is that just applied for Retina displays? What happens on 4k displays? Yes, I don’t know what I’m doing and I admit it! This whole UI sizing effort is new to me and quite a “challenge”. Is there something you can point me to that explains all of this? ---

Either way will scale. You could try just supplying x2 bitmaps and then they will get scaled down for 100% display if I recall correctly to make things less fuzzy. I’m not sure how 4k is defined but high-res screens on windows or Mac will use the high-res bitmaps.
