I am trying to save each image in an array as a .PNG file (also as the right size, without scaling up because of retina mac dpi issues) and can't seem to find a solution. NONE of the solutions at How to save PNG file from NSImage (retina issues) seem to be working for me. I've tried each one and each of them would still save a 72x72 file as 144x144 in retina .etc. More specifically I am looking for an NSImage category (yes, I am working in the Mac environment) I am trying to have the user Choose a directory to save them in and execute the saving of the images from array like this: - (IBAction

According to an article on CSS-Tricks , the future proof media queries for retina display can be wrote as: @media only screen and (-webkit-min-device-pixel-ratio: 2), only screen and ( min--moz-device-pixel-ratio: 2), only screen and ( -o-min-device-pixel-ratio: 2/1), only screen and ( min-device-pixel-ratio: 2), only screen and ( min-resolution: 192dpi), only screen and ( min-resolution: 2dppx) { /* Retina-specific stuff here */ } What if I want to write CSS codes for non-retina display? I know you can write some CSS codes for non-retina display first, and then overwrite it for retina display

I have issues to load 512x512px tiles in MKMapKit. The Server provides 512x512 .jpeg tiles. I could not find any solution or sample implementation for custom retina tiles in MKMapView. What I do: When I load them into MKMapView with overlay = [[MKTileOverlay alloc] initWithURLTemplate:template]; overlay.tileSize = CGSizeMake(512.0f, 512.0f); [_mapView insertOverlay:overlay atIndex:MAP_OVERLAY_INDEX_TILE level:MKOverlayLevelAboveLabels]; … tiles are scaling correct but only half of them is loaded (not only visually - i sniffed the requests and the tiles are missing) with overlay = [

I have been using Emacs 24.4 for all my math/scientific notes. org-latex-preview is fantastic for this! But recently, I upgraded to a macbook pro with retina display, and I now see that all my equations in org-mode are... fuzzy. Is there a setting I can change to up-res these? Here is a screenshot: Thanks! A couple of years back, I decided to fix this and wrote a patch to add dvisvgm as a render option for latex previews.

I am trying to get to grips with media queries for different devices. I have tried my new Sony Xperia Z mobile and displays in full scale site format due to the high resolution. How do I add a media query to re-size a grid and format like a standard mobiles scale? On the Xperia the font is also too small to read and needs to show bigger. Is this a problem for retina devices that act like full size monitor displays? Xperia Z - resolution 1920 × 1080, PPI 443 How do I include media queries for such devices? Timidfriendly This code targets all devices with the same pixel ratio, which is actually
