Read the angles hidden in your photos.

Stria measures the horizontal coverage of panoramas, near-panoramic images and rectilinear photos. Align the grid, calibrate the scale and annotate the scene.

Stria in landscape mode during an angular measurement

An angular scale for every photograph.

Choose how to estimate the image coverage and Stria converts pixels to degrees, directly on the photo.

EXIF for rectilinear photos, 360 for equirectangular images, Cylindrical for partial panoramas, Manual or 2 points for calibration.

Drag the central reference and grid lines to read directions and angular separations in the scene.

Save an annotated screenshot to your Photo Library with the grid, references and measurements visible.
