The Perspective Crop tool combines two operations into one – correcting perspective and cropping. The tool can be used to fix perspective distortions, which can occur when taking pictures of wide or tall objects with a camera at an angle to the subject.
Note. The tool is only available for Home and Pro licenses.
The rectangular crop area is created by dragging the cursor with the left mouse button pressed.
When clicking the image while holding down the Ctrl key (with the tool selected), the crop frame will cover the entire image area.
If there is an active selection on the image, then the crop frame will cover the selection area.
Drag the corner markers to change the perspective of the contour. When moving the markers, it is necessary to ensure that the sides of the frame become parallel to the sides of the object being corrected.
Hint. Blue markers on the frame indicate where the top of the cropped photo will be.
Tool settings are displayed in the Tool Options panel above the Image Window.
In the Trim section, specify the method for creating the crop area:
Manual. A crop frame is created manually using the mouse cursor.
Trim Alpha. A crop frame will be created based on the contents of the alpha channel.
Trim Selection. A crop frame will be created based on the contents of the selection channel.
Top Left Color. Areas having the same color as the upper left pixel in the image will be placed outside the crop frame.
Bottom Right Color. Areas having the same color as the lower right pixel in the image will be placed outside the crop frame.
You can select the side from where to crop the picture: Top, Bottom, Left, Right. This option is disabled for the selected Manual mode.
External Area. The check-box helps to facilitate visualization of the crop frame. If the check-box is enabled, the outer parts are highlighted in a selected color.
Show Grid. When the checkbox is active, a grid is displayed above the crop area, which helps when adjusting the crop frame.
To complete the perspective cropping, click OK or press the Enter key. After that, the crop area will convert to a rectangular shape, and everything outside the frame will be deleted.
