Apply a mask to place your image within a cutout shape.
To add a mask, select one or more image or shapes on your page, then click on the Gradient and Mask tool. Scroll down to the Mask section.
Note that masks can also be applied to Shapes.
Memento Pro is bundled with a collection of masks. These are available from the first drop-down box.
To apply a mask to your selected image, click on the V to select one of the available options.
Use the soften option to blur the edges of the mask.
Mask Cropping Options
Choose among three cropping styles.
Fit the image frame applies the mask to the current shape of the image. The mask is reshaped from its original aspect ratio to accommodate the image.
Original aspect ratio preserves the mask's aspect ratio. Unless your image and the mask are the same aspect ratio, more image is cropped out by the mask.
Follow image crop maintains the aspect ratio of both the mask and the image - the results may include the occlusion of the edge of part of the mask.
Use the invert mask option to flip the transparent/image content areas.
This is best used as framing effect, applied to a shape or an image frame holding a texture.
For example, this layered effect was created by adding two images (a photo and textured image) with the same aspect ratio and the same mask. The mask on the texture image is inverted.
Should you wish to import a custom collection of masks saved to jpg format, use the Alpha/RGB options to ensure the mask works correctly. Masks save to jpg may require special settings to assign rules to transparency areas (alpha channel). The stock collection and png mattes generally do not need adjustment - "alpha only" will get you best results.
Note that you can apply masks on Shape frames.
