Subcommand: find
-
Supported Platforms: Native (legacy), UFT (legacy), Selenium, Appium
All commands must be executed using the same framework. Sharing the execution ID between different frameworks is not possible. This means that if you work with a Selenium/Appium driver, you need to call the commands using the Selenium/Appium driver (or, in the case of Reporting commands, through the Reporting SDK that works with the driver) and not as part of a UFT test or another framework.

Supported OS: Android, iOS
Description
Finds an image (needle) on the device screen (haystack) and stores the coordinates for future commands. By default, the find image function searches for the image on the current screen.
If the image is not on the current screen, enable the Scroll and search parameter. When enabled, the default scroll direction is down. For iOS devices, the default scroll direction is right. To change the scroll direction to down, select body as the Search area.
For more information on how to use the Next parameter, see Create custom swipe gestures
This command should be used in combination with Visual Relations .
Parameters
| Name | Value | Default | Description |
|---|---|---|---|
| deviceId* | The device for this command. | ||
| content* |
The image to search for. The image can be taken from the device screen using the preview tool or selected from the media repository. If selected from the repository the image must be a JPEG, PNG or BMP file. |
||
|
context |
all (all) body (body) lowerPanel () upperPanel () |
all |
Defines the screen region where to look for the needle. |
|
source |
primary (Primary) camera (Camera) secondary () |
The source for retrieving the screen content. Primary - Digital screen image Camera - Analog screen image |
|
|
screen.top |
The top value of the screen area where to search for the needle. Values can be in pixels or in percentage of screen width (0-100). For percentage, use the % sign. Example: 20% Default is to search the entire screen. Consider using the percentage value because it does not rely on the screen resolution. |
||
|
screen.height |
The height value of the screen area where to search for the needle. Values can be in pixels or in percentage of screen width (0-100). For percentage, use the % sign. Example: 20% Default is to search the entire screen. Consider using the percentage value because it does not rely on the screen resolution. |
||
|
screen.left |
The left value of the screen area where to search for the needle. Values can be in pixels or in percentage of screen width (0-100). For percentage, use the % sign. Example: 20% Default is to search the entire screen. Consider using the percentage value because it does not rely on the screen resolution. |
||
|
screen.width |
The width value of the screen area where to search for the needle. Values can be in pixels or in percentage of screen width (0-100). For percentage, use the % sign. Example: 20% Default is to search the entire screen. Consider using the percentage value because it does not rely on the screen resolution. |
||
|
image.top |
The top value of the image area defining the needle. Value is in pixels. Default is the entire image. |
||
|
image.height |
The height value of the image area defining the needle. Value is in pixels. Default is the entire image. |
||
|
image.left |
The left value of the image area defining the needle. Value is in pixels. Default is the entire image. |
||
|
image.width |
The width value of the image area defining the needle. Value is in pixels. Default is the entire image. |
||
|
timeout |
0 |
The time, in seconds, to wait for the needle to appear. For a dynamic screen, specify the expected waiting time for the needle to appear. For example, the page loading time. The timeout contains the system analysis time, for this reason it is recommended to specify at least 20 seconds. The default, defined as 0, is a single attempt to find the needle. |
|
|
measurement |
rough (Rough) accurate (Accurate) |
Rough |
The timer accuracy level. Rough - Normal accuracy (seconds) Accurate - Sub second (0.1 second) To use this parameter, Screen source must be Camera |
|
threshold |
The acceptable match level percentage, between 20 and 100. Too low values can lead to a false positive result, while too high values can lead to a false negative result. |
||
|
duration |
0 |
The duration, in seconds, the found needle should remain on the haystack. |
|
|
interval |
0 |
The minimum time interval, in seconds, for a single analysis. If the analysis operation takes less than the interval, wait the remaining time before the next analysis operation. |
|
|
backlight |
The key sequence to perform the backlight operation. Example - VOL_UP For best practice, use a key that will not change the screen. |
||
|
scrolling |
noscroll (False) scroll (True) |
False |
Scroll until the needle is found. Scroll cannot be used together with a positive Timeout, because they dictate a different behavior when the needle is not found. When scrolling is enabled, the timeout must be zero. Scroll results in a longer execution time. |
|
maxscroll |
5 |
The maximum number of scroll actions to perform before returning. Finding the needle will stop the scrolling. Effective values are in the range of 0-100. |
|
|
next |
SWIPE_UP (SWIPE_UP) SWIPE_DOWN (SWIPE_DOWN) SWIPE_RIGHT (SWIPE_RIGHT) SWIPE_LEFT (SWIPE_LEFT) UP (UP) DOWN (DOWN) RIGHT (RIGHT) LEFT (LEFT) |
The key sequence to perform the scroll operation. For more information, see the Create Custom Swipe Gestures post. |
|
|
match |
identical (Same size) similar (Any size) bounded (Bounded size) |
The needle comparison method. Same Size - needle and haystack are from the same origin (device screen) and size, matching is faster and simpler Any Size - needle and haystack are either not from the same origin (needle is from another device or other source) or not in the same size (different ratio or size), matching is slower and more complex. Selecting Any Size increases the analysis time. The timeout values should respectively be increased. Bounded Size - same as Any Size with restrictions on possible needle sizes. This mode allows decrease the any size analysis time by using apriori knowledge on needle sizes or by decreasing the size of a haystack. |
|
|
matchGeneric |
A generic image compare parameter. Use this to provide additional image compare specifications that are not exposed as function parameters. Examples: matchMethod=TM_SQDIFF_NORMED matchMethod=TM_CCORR_NORMED |
||
|
report |

|
report.resolution |
high (High) medium (Medium) low (Low) |
High |
The image resolution. Consider reducing the resolution in very long scripts that result in large report files. |
|
grid |
The column name to be used for grid view in the report. Selecting this parameter creates the grid report. |
||
|
relation.direction |
left (Left) right (Right) above (Above) below (Below) left-above (Left-Above) left-below (Left-Below) right-above (Right-Above) right-below (Right-Below) inside (Inside) |
The direction of the related region, stored in memory from the last found needle, in relation to the searched needle. For more information, see the Visual Relations series. Left - The related region is to the left of the searched needle Right - The related region is to the right of the searched needle Above - The related region is above the searched needle Below - The related region is below the searched needle Left-Above - The related region is to the left and above the searched needle Left-Below - The related region is to the left and below the searched needle Right-Above - The related region is to the right and above the searched needle Right-Below - The related region is to the right and below to the searched needle Inside - The searched needle is inside the related region boundaries of the related region |
|
|
relation.inline |
horizontal (Horizontal) vertical (Vertical) |
The search area is in-line with the related region, stored in memory from the last found needle. For more information, see the Visual Relations series. Horizontal - The needle is within the height (top to button) boundaries of the related region Vertical - The needle is within the width (left to right) boundaries of the related region |
|
|
imageBounds.needleBound |
The ratio in percentage by which the original needle width may vary. The ratio is defined as a (100 - specified percentage) / 100. Needle sizes to be checked by the analysis will be limited to the range from original needle width multiplied by the ratio to the original needle width divided by the ratio. To use this parameter, Match mode must be bounded size. |
||
| imageBounds.haystackArea |
786432 |
The size of haystack to be used for the analysis. The haystack image will be scaled before being analyzed so its area does not exceed the specified value. Haystack images that do not exceed the value will stay unchanged. To use this parameter, Match mode must be bounded size. |
|
|
x.alignment |
none (None) left (Left) center (Center) right (Right) |
None |
None - Do not check for horizontal alignment Left - Needle should be left aligned Right - Needle should be right aligned Center - Needle should be horizontally center aligned. |
|
x.width |
Value specify the amount of allowed accuracy to still match the required alignment. (e.g. if 10% is used and the target is located at position 15 out of 320 than the validation succeed) |
||
|
y.alignment |
none (None) top (Top) center (Center) bottom (Bottom) |
None |
None - Do not check for vertical alignment Top - Needle should be top aligned Bottom - Needle should be bottom aligned Center - Needle should be vertically center aligned |
