Image Capture To Scan

Download Image Capture For Windows. Free and safe download. Download the latest version of the top software, games, programs and apps in 2021. First, identify the menu or other components you want to capture. In Snipping Tool, select Delay and then select, for example, 5 seconds. Select Mode to start the 5-second countdown. Within 5 seconds, open a menu or otherwise compose your image. At 5 seconds, when you see the screen turn gray, use the mouse to draw around the area you want.

In the Viewer window, you can move the Capture Area by clicking the desired location, dragging the Capture Area, or pressing the arrow keys. Pressing an arrow key alone moves the Capture Area one pixel in the given direction; to move the Capture Area in 10-pixel increments, hold down Shift as you press an arrow key.

To adjust the image scale to offer a better perspective for screen actions, click to enlarge the image size and to reduce the image size.

Note: The initial view of the captured image is shown at a 1:1 scale.

Identifying Good Images

An easy way to keep Eggplant Functional scripts as robust as possible is to capture images with just enough content to uniquely identify an interface element. For example, here is an image of a folder on a desktop:

If you capture some of the desktop in your image, you always have to rely on the desktop color to be the same for a match. Even if you can always count on the desktop being the same color, in this example, it is shaded when the folder icon is selected:

When you have the Capture Area in roughly the size and position you need, you can use the arrow keys to fine tune it:

To nudge the Capture Area one pixel at a time, press the arrow keys.
• To adjust the size of the Capture Area one pixel at a time, press Alt+arrow (Option+arrow on Mac) keys.
• To nudge the hot spot one pixel at a time, use Ctrl+arrow (Cmd+arrow on Mac) keys.

Using the Hot Spot

The position of the hot spot is defined as an (x, y) offset relative to the upper-left corner of the captured image. For example, if you capture an image that is 20 pixels wide and 10 pixels high, and you leave the hot spot at its default location in the center of the image, the hot spot location is reported as (10, 5)—10 pixels to the right of and 5 pixels down from the upper-left corner.

Although the hot spot is associated with an image, it doesn’t have to be inside the image. For example, if you need to select text in a text box, there is no way to do an image match unless you know in advance what the text is going to be. Instead, you can capture an image of the text box’s label, and set the hot spot a few pixels over, where the actual text box begins, as shown in the image below:

When you save an image, the Capture Image panel gives you a choice of search types. Eggplant Functional tries to automatically detect the appropriate search type for your image, but in some cases you might want to override the default setting. If an Eggplant Functional script suddenly fails to find an image that it found on a previous run, try changing the search type in the Info panel of the Images pane. Search type changes are saved immediately, and the new search type is used the next time a script calls that image.

Important: The search types visible will depend on whether or not you have Show all search types enabled in your General Preferences. By default, three search types will be visible: Tolerant of Background, Smoothed for Text, or Adaptive to Image. Selecting this checkbox in your preferences will allow Eggplant Functional to also display Precise to Pixel, Pulsing to Element, and Smooth and Pulsing. Precise and Pulsing can be chosen by Eggplant Functional as the default search type, even if those are not shown.

Typically, Eggplant Functional chooses the Tolerant of Background search type. The Tolerant setting works well for most images, and allows for some variation in the colors of the image when it is found. A good example is a semi-transparent window or menu. In the images below, you can see objects in the background through the menu on the right. The Tolerant setting allows Eggplant Functional to accurately locate menu items, even if the screen behind the menu is in a different state than it was when the image was captured.

This search type is designed to deal with text and buttons that sometimes change their appearance subtly, primarily due to Mac text anti-aliasing. If you are testing against Mac systems, using the Smooth (or Smooth and Pulsing) search type can make a big difference in your images that include text.

This search type uses a flexible search algorithm to analyze individual pixels and then also look at the overall similarity before determining a match. The effect is that of seeing the image as a whole, similar to how a human would see it. This makes it significantly easier to match images across different devices as resolution and scale change. Because of this, when doing cross-device or cross-platform testing, you might want to use the Adaptive to Image search type along with Image Scaling.

The Precise to Pixel search type requires a very high degree of precision to consider an image matched on the SUT. This setting is useful for low contrast images or images with subtle color differences.

Pulsing buttons, such as the Save buttons in some versions of Mac, can also be detected automatically by Eggplant Functional. The Pulsing setting causes Eggplant Functional to use a 'mask' on the image to filter out the pixels that are changing.

If hovering over an element obscures an element, it might make sense to have the cursor automatically get out of the way. To accomplish this change, set the shouldRepositionMouse global property to yes. Doing so changes Eggplant Functional's behavior such that if it fails to find an image it is looking for on the first search, it moves the mouse to the lower right-hand corner of the screen. This change makes sure the image is no longer being obscured by the cursor.

If Eggplant Functional continuously fails to find a particular image, and you have ruled out search type and timing problems using the Image Update Panel, it might be that the SUT is not displaying the image consistently.

The procedure outlined below describes how to view the differences between these images on a pixel-by-pixel basis. Adobe Photoshop Elements is used here, but you can adapt this technique for use with the graphics program you typically use.

Open both images. In the graphics program, open the saved image and the Screen_Error file for a script run that failed because of this image.
2. Overlap the images. Copy the saved image, and paste it on top of the Screen_Error file. In Photoshop, the copied image is automatically pasted into a separate layer.
3. Align the images. Use the Move tool to drag the saved image to its corresponding location in the Screen_Error file. Then zoom in and adjust the image further by nudging it with the arrow keys.
4. Highlight the differences. In the Layers palette, click the Blending Mode pop-up menu and choose Difference.
5. Evaluate the differences. Pixels that match perfectly are displayed as black. For other pixels, look at the Info panel to see the RGB values for each image. The greatest difference between the three values is the tolerance Eggplant Functional must allow to consider that pixel a match in both images. For example, if a pixel in the saved image has RGB values (99, 99, 135), and the same pixel in the Screen_Error has (100, 100, 150), the search tolerance must be at least 15, or the difference between the blue values.

When you are scripting, you often need to use the same image more than once within a suite or script. For example, you might click the File menu repeatedly, or open a number of dialogs with OK buttons.

Screen Image Capture

Alt+click (Option+click on Mac): In the Viewer window toolbar, Alt+click (Option+click on Mac) a command button. Instead of capturing an image, the command opens a Use Image panel so you can select an existing image. The command that you click is both added to the script and performed on the SUT.

• Insert Pop-up Menu: In the Script Editor, choose a command (or Additional Image for no command) from the Insert pop-up menu, then select your image in the file browser. The command you choose here is not performed on the SUT.

• Drag-and-drop: Drag an image from the Images pane of the Suite Editor to the script.

• Copy and paste: Copy and paste from another part of the script. You can always type an image name in quotation marks, too.
