I have Acrobat Reader DC (19.008.20081), with a large image (9000 across x 12300 high pixels). I am using the tiling features of Reader DC to print to jpg images, printer being ImagePrinter Pro print-to-image utility.
I want the tiles printed landscape to fit A4, but despite setting landscape everywhere there is such an option(Properties, Page Setup, also in Control Panel), it keeps trying to tile portrait. How do I force it to print landscape to images?

I have scanned my copybook and want to crop out extra white regions with Inkscape.
To achieve this, I import initial image (PDF) to Inkscape, draw appropriate rectangle, and use Object->Clip->Set to cut out needed region. Then I resize page to drawing and save obtained page as new PDF file through File->Save a Copy.
I expected that the size of the new PDF file (with cropped image) will be less than the size of the initial PDF (with image without crop), but they are the same.
What is the reason of this and may it be worked around?
I use Inkscape 0.91 at Linux Mint 18.2.
Thank you in advance.
Because the original image is still there, fully intact and with all its contents. The cropping rectangle are just instructions to the PDF viewer to crop out those regions when rendering the image.
However in Inkscape you can bake the crop rectangles and when exporting to PDF "apply raster effects" which should actually alter the contained image(s).
Im rendering a pdf using pdf js library. There I can specify zoom (scale) property. Which is fine. I can define pretty high zoom , let's say 8x and still get decent quality of the rendered pdf. However if I were to try to same pdf but converted to graphic image format like jpeg. And then try to render it with high zoom the quality is very bad. Why is that so?
You are describing the difference between vector graphics and raster graphics. A vector graphic format contains contains commands telling how to draw an image. A raster format is an array that tells what the color is at each position in the image.
PDF is largely a raster format (Yes, you can embed a raster image in a PDF). A PDF that has in instruction to draw a line or draw a character can be zoomed to any degree and the drawing will be correct.
In a raster format, if you zoom, eventually you see the individual pixels in the array and they cannot be zoomed any more without distortion. Text in a JPEG or PNG file becomes jagged as you zoom.
On the other hand, try to create a photographic quality image just with drawing commands and you would get huge files.
to submit the new version of my application, i had to add screenshot in 5,5 inches, 4,7 inches and 12,9 inches.
according to the "iTunes Connect Developer Guide=> Screenshot properties" the following resolution are allowed to be upload on the appstore
Screenshot requirements are:
72 dpi, RGB, flattened, no transparency
High-quality JPEG or PNG image file format
Any of the following sizes:
640 x 920 pixels for hi-res portrait (without status bar) minimum
640 x 960 pixels for hi-res portrait (full screen) maximum
960 x 600 pixels for hi-res landscape (without status bar) minimum
960 x 640 pixels for hi-res landscape (full screen) maximum
But each time i want to upload a screenshot i got the following message:
Les dimensions d’une ou plusieurs captures d’écran sont incorrectes. En savoir plu
without any additional advice.
Is there any other restriction on the format file to be approved by itunesconnect??
My picture is 640x960 72dpi rgb in jpeg format.
I don't know what to do and how i can upload my screenshot to upgrade my app...
Thanks for your help
Welcome to StackOverflow! Looks like you are trying to upload the wrong sizes:
The following sizes are allowed/available in iTunes Connect:
From what you have written above, it looks like you wanted to upload 3.5-inch screenshots (640x960) for the 4.7-inch iPhone, but only 1334x750 or 750x1334 are allowed screenshot sizes for that category.
If you don't have a different behaviour on the 4.7-inch iPhone compared to the 5.5-inch version, I recommend using the Media manager and using the 5.5-inch screenshots for all other sizes.
What size should an application icon and menu bar icon for OS X be?
I can deal with small resolution displays but what about Retina - does an icon displayed on the menu bar (e.g. 20 x 20 ) will be smaller or blurred on a new MacBook Pro with Retina display?
I reckon that the Application icon will be scaled, so if I'll prepare twice larger than regular it should be OK on Retina.
I found an excellent guide for iOS development with sizes specification but I can't find similar size specifications for OS X.
NSStatusBar icons (i.e. Menu bar icons) are different from regular app icons. I have not been able to find an NSStatusBar official icon guideline, but I have to believe that the Toolbar Icon guideline for buttons is pretty close. It suggests:
Create icons that measure no more than 19x19 pixels.
Make the outline sharp and clear.
Use a straight-on perspective.
Use black (add transparency only as necessary to suggest
dimensionality).
Use anti-aliasing.
Use the PDF format.
Make sure the
image is visually centered in the control (note that visually
centered might not be the same as mathematically centered).
In testing, I've found:
NSStatusBar seems to look best with something 18 pixels high, or less. The systemStatusBar has a thickness of 22.
While it lists PDF format, I've been using png without issue.
If you want your icon to be white on blue when it's selected, you need to provide the alternateImage as a separate white version of your icon.
Code sample:
myStatusItem = [[NSStatusBar systemStatusBar]statusItemWithLength:NSSquareStatusItemLength];
NSImage *statusImage = [NSImage imageNamed:#"Status.png"];
[myStatusItem setImage:statusImage];
NSImage *altStatusImage = [NSImage imageNamed:#"StatusHighlighted"];
[myStatusItem setAlternateImage:altStatusImage];
[myStatusItem setHighlightMode:YES];
[myStatusItem setMenu:self.myStatusMenu];
To make your menu item support Retina displays, Dark Mode and different states (e.g. pressed)
Create two PNG images sized 16x16 and 32x32 pixels
Create a new image asset in Xcode with Render As set to Template Image and add your images for 1x and 2x
Initialize your NSImage from the image asset without changing its size: NSImage(named: "Example")

Follow these steps and you will get a perfectly sharp status bar Icon for retina
Open a png file of your Icon in photoshop it should be larger than 88px x 88px
go to menu, Image, Image size
set resolution to 350
set size to 88px x 88px (pixels)
save image as png
add it xcode
adding on to Michael's answer apple are now requiring all the way up to 1024x1024px icons due to retina displays.
http://www.cultofmac.com/179738/apple-now-requires-high-res-1024x1024-icons-for-every-mac-os-x-app/
The maximum size for the app icon should be 1024 x 1024.
And you have to create both regular and retina resolution icons for 16 x 16, 32 x 32, 128 x 128, 256 x 256, 512 x 512 & 1024 x 1024.
The details for which you can find in the "High Resolution Guidelines for OS X" document from Apple.
I have a PNG picture which I should use in my iPhone application, but first of all, I have to give it the dimensions of an iPhone 4 retina screen. Does any one know what could it be its dimensions or how to do that?
The retina display on the iPhone 4 has the double amount of pixels than that of an older iPhone. So the complete size of an iPhone 4 screen in pixels is 640x960.
In photoshop you can quickly resize any image by changing the image size property from the Image menu. If you don't want to lose quality I suggest you start with all retina images and halve them for the non retina displays. Doing it the opposite way will decrease your quality.
If you want to use an image designed for the iPhone 4 retina display you'll want to have both pictures, one for the normal iPhone screen (320x480) and one for the retina images, in your resource's folder of your Xcode project. Use the same name for those images but append "#2x" at the end of the retina images.
So if you have a "background.png" it will become "background#2x.png" and iOS will be smart enough to use the correct image for the correct type of screen.
At 72 dpi, it should be 640px by 960px.
iPhone4 screen resolution is 960x640
