Working in the Edit workspace of Photoshop Elements gives you choices about working with your files. You can set options for opening, saving, and exporting files by type, by file size, and resolution.
You can also process and save camera raw files. These tools make it easy to combine files of different types and optimize them in Adobe Photoshop Elements. In the Edit workspace, you can create a blank file, open a recently used file, specify which files types to open in Photoshop Elements, and more. An additional option for working in the Edit workspace is to use the Guided Edit feature.
They empower users to complete complex editing workflows in a small number of easy steps. You may want to create a web graphic, banner, or company logo and letterhead, in which case you need to start from a new blank file.
Select Clipboard to use the size and resolution of data that you copied to the clipboard. You can also base a new image on the size and resolution of any open image by choosing its name from the bottom of the Preset menu. Width, Height, and Resolution. Sets these options individually. Background Contents. Sets the color of the image Background layer. White is the default. Select Background Color to use the current background color shown in the toolbox.
Select Transparent to make the default layer transparent, with no color values—the new image will have a Layer 1 instead of a Background layer.
You can also right-click the background of an image to choose a background color gray, black, or a custom color. You can open and import images in various file formats. The available formats appear in the Open dialog box, the Open As dialog box, and the Import submenu. Locate and select the file you want to open. Click Open. Click the Open drop-down above the tool box. The Open drop-down is a list of recently opened files. There may be instances when Photoshop Elements cannot determine the correct format of a file.
In such cases, you must specify the correct format in which to open the file. Portable Document Format PDF is a versatile file format that can represent both vector and bitmap data and can contain electronic document search and navigation features. You can choose to import full pages including text and graphics , or you can import just the images from a PDF file.
If you import only the images, the resolution, size, and color mode of the images remains unchanged. If you import pages, you can change the resolution and color mode. Each page is shown as a thumbnail. To increase the size, choose an option from the Thumbnail Size menu. If the file contains multiple pages, select the page or pages you want to open, and click OK.
Specify the Width and Height. Enable Constrain Proportions to avoid image distortion due to change in size. For Resolution, accept the default ppi or type a new value. A higher resolution increases the file size. Choose an option from the Mode menu RGB to keep the photos in color, or Grayscale to automatically make them black and white.
You can place pages or images from PDF files into a new layer in an image. Because the placed artwork is rasterized bitmapped , you cannot edit text or vector data in placed artwork. The artwork is rasterized at the resolution of the file into which it is placed. The placed artwork appears inside a bounding box at the center of the Photoshop Elements image.
I've written the following code to read a list of names one per line from a file into another file while checking a name against the names in the file and appending text to the occurrences in the file. The code works. Could it be done better? I'd wanted to use the with open Python allows putting multiple open statements in a single with. You comma-separate them. Your code would then be:. And no, you don't gain anything by putting an explicit return at the end of your function.
You can use return to exit early, but you had it at the end, and the function will exit without it. Of course with functions that return a value, you use the return to specify the value to return.
Using multiple open items with with was not supported in Python 2. If you are writing code that must run in Python 2. This is better than your version because you guarantee that outfile will be closed even if your code encounters exceptions. Or, as I have just learnt, you can have multiple context managers in a with statement as described by steveha. That seems to me to be a better option than nesting.
Sometimes, you might want to open a variable amount of files and treat each one the same, you can do this with contextlib. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
