When you select a color with the eyedropper, the rectangle shows the color you selected. Next to the eyedropper button, you'll see the color picker. You can lower the tolerance setting to select colors closer to the original pixel clicked (fewer pixels) or choose a higher tolerance value to select a wider range of similar colors (more pixels).
When you use the eyedropper to select a color, the editor automatically provides a tolerance range around the pixel you clicked. For Keep, the color you select remains while the rest of the pixels become transparent.īecause images typically have slight variations in color, pixel to pixel, beneath the eyedropper buttons you'll see a tolerance slider. For Ignore, all the pixels that match the color you select become transparent just as if they had been erased. The Keep Color feature lets pick a color to keep while every other color is ignored.Ĭlick the eyedropper button, then use the eyedropper cursor to select the color in the image. The Ignore Color feature lets you choose a color to mask out of the image. Ignore Color & Keep Color: These features let you mask a portion of the image based on your color selection. Restore: Use the Restore to tool to return previously removed pixels to the image. You can use Zoom In to view the image larger and allow for fine-grained editing of the pixels. This tool can be useful if you want to remove the background from a shaped image (a circle or some unusual shape), for example, or you want to remove pieces from the middle of an image. The original image borders show as dashed lines, and you can drag image margins out to restore previously cropped portions of the image.Įrase: Use the Erase tool to selectively remove parts of the image. Click the Crop button, then drag to adjust the edges of your image where you want them.
This is a view change only it doesn't change the actual size of the image.Ĭrop: Use crop to change the margins of your image. Zoom: Use the Zoom In or Zoom Out buttons to changed the view of the image in the editor window. What follows is a brief discussion of using these tools in Eggplant Functional. The editing functions in the sidebar should be familiar to anyone who has done basic image editing before. However, be sure to save changes before switching to a new image. You can use this browser to pick different images to edit while you're in the Image Editor. Tip: The Image Browser remains at the bottom of the edit screen. Pick a color that provides a good contrast with the colors that you plan to keep in your image. However, because you'll be working with transparency while editing, the background color choices in the editor are bright colors instead of shades of gray. Much like the Image Well in the Image Viewer, you can change the background color on which your image is shown by clicking in the edit window. The image is displayed in the main editing window, and the control buttons are on the sidebar to the right. The Image Viewer switches to the Image Editor for that image without opening a new tab. You access the Image Editor by clicking the Edit button when an image is displayed in the Image Well of the Image Viewer in the Suite window. But keep in mind that sometimes less editing-or no editing-might be the better choice. You should know what works best in your environments and for the applications you are testing. However, the image matching algorithm could then find that image in a pure black field because within that black space, it could match the pattern for the black letters. For instance, if you had black text on a white background, you might be tempted to remove all the white from the image, leaving crisp black letters. When Eggplant Functional scripts search for images, transparent sections of images are ignored-that is, image matches are based on non-transparent parts of the image only.īe careful about removing too many pixels to the point where an image lacks sufficient context to distinguish it.
When you use the Image Editor to erase a portion of an image, or you choose to ignore pixels based on color, that portion of the image becomes transparent. The functions available in the editor are as follows:Įach of these features is described in detail below. However, note that you can always return to the original file, even if you have saved changes for an edit. The Image Editor lets you alter or ignore pixels within an image.
Although the best practice for images is to capture images on your systems under test (SUTs) as you expect your scripts (and users) to find and interact with them, sometimes editing can improve Eggplant Functional image matching. The Image Editor in Eggplant Functional lets you perform basic image editing tasks on image files that you've either captured or imported into your suite.
