![]() ![]() These problems may show when printing our profiling charts using the Adobe utility, or when printing images from Photoshop, Lightroom, or other applications with 'Application Colour Management'. There are some Mac users who are unable to print without Colour Management problems when using various printers. The Faulty Airprint Printer DriverĪs this is probably the oldest and most common Mac printing problem we should probably deal with it first. This is written with photographers in mind, so you may find more in-depth information and solutions elsewhere. There's also some advice on Mac 'housekeeping' and why not to rush in and upgrade to the latest version. We explain a few of them here, along with possible fixes or work-arounds. Over the past few years, especially since the release of Apple's macOS 10.14 'Mojave' and later versions, several colour problems were reported by our customers and on internet photographic fora. Because of that, I had to have special code to look up mainScreen.backingScaleFactor so that I could adjust the size of the image.Printing and Other Problems in macOS, especially 'Mojave', 'Catalina', 'Big Sur' and NOW 'Monterey' and maybe 'Ventura'. I originally used lockFocus for the ASCII art script because that’s what all the examples I found used. Now that I have it, I use it all the time, so plug for the book. Partly this is because I wanted to do it long before the computers I owned had the capability, and by the time they did it was one of those things on the back back burner. While I had long wanted to be able to create ascii artwork from my photos, I hadn’t gotten around to it. The asciiArt script is the only script in 42 Astounding Scripts that I wrote specifically because I was gathering my most-used scripts for a book. That was the key to jettisoning lockFocus. The code in the block should be the same code that you would use between the lockFocus and unlockFocus methods. On that page, it said something, albeit without examples, that I hadn’t seen before: While writing text2image I ran across Apple’s page recommending against lockFocus for creating image files. This means that a command-line script written using lockFocus will change its behavior depending on what kind of a monitor you’re using. That’s a problem, because lockFocus does things that only make sense when displaying to a screen, such as automatically changing the number of dots in the image depending on whether your screen is a retina screen. Most of the few remaining examples continue to use lockFocus probably because that’s what gets used most often for examples. They use lockFocus() to create the image. Almost all of the examples of creating images in Apple’s documentation and on sites such as stack overflow assume that you’re creating images to display to the screen. If you’ve read 42 Astounding Scripts, this is an image-oriented variation of my alignTabs script and makeHTMLTable script.īoth asciiArt and text2image take text and create images out of the text. It has pretty much only one use case, online outlets that accept images but not tables. It is both a more serious program than asciiArt and more frivolous. Originally for converting tabular data to an image I now use it for taking paragraphs and wrapping them and justifying them or aligning them right or center. I wrote another script more recently that takes standard input and converts it to an image of the text. But I’ve since extended the script to include color, color overlays, and random color, as well as sequential text instead of text chosen for its density. I wrote it to do basically what ascii art used to be, an ingenious method of greyscaling images at very low resolution. My favorite of these wee hour efforts is a script I wrote for 42 Astoundingly Useful Scripts and Automations for the Macintosh to turn photographs into ascii art. These are the kind of scripts that bring me back to ma jeuness of staying up into the morning hours programming. Among the coolest uses of command line scripts in Swift on the Macintosh are those that intermediate between images and text. ![]()
