Image Editor

A lightweight image editor built into Yeero Desktop: jump straight in after a screenshot, or open any local image. Annotate with 9 tools — rectangles, arrows, mosaic and more — then crop, rotate, resize and knock out the background with smart transparency, all backed by layer management and an EXIF viewer, covering everyday touch-ups and bug-report screenshots.

Overview

The image editor runs in its own window, independent of the main window, and multiple instances can be open at once. It is designed around "annotate fast, share faster":

• Supports PNG, JPG, JPEG, WebP, BMP and GIF
• 9 annotation tools, each with a number hotkey — select and go
• Image processing: crop, rotate, flip, resize and smart background transparency
• Full undo/redo history; every action can be reverted
• A layers panel to manage all annotations: visibility, ordering, deletion
• One-click copy to clipboard, paste straight into chat apps or documents
• Built-in image info panel with basic parameters and full EXIF data

Opening Images

There are four ways to get into the editor:

1. Automatically after a screenshot — once you confirm the region via Screenshot or the Launcher, the editor window opens with the capture loaded
2. Open a file via the Launcher — paste or type an image path in the Launcher and press Enter to open it in the editor
3. Open from the menu — press Ctrl+O or click the "Open Image" button to pick a local file
4. Drag & paste — with an empty window, drag an image file in, or press Ctrl+V to paste an image from the clipboard

The window automatically resizes itself to fit the actual image dimensions, so small images don't stretch across the screen and large images are never cropped.

Annotation Tools

The toolbar sits at the top of the window; every tool has its own hotkey (on narrow windows some tools are folded into a "More tools" dropdown):

Objects stay editable after drawing: pick one with the Select tool to move or resize it, or change its color, stroke width and other parameters in the properties panel.

Image Processing

The toolbar offers a group of image-processing actions to the right of the annotation tools. They operate directly on the base-image pixels, transform existing annotations in step, and are all wired into the undo history:

• Crop (C) — once active, a crop box appears on the canvas; drag its 8 handles or move the whole box to pick the area you keep. The floating bar offers aspect presets (free / 1:1 / 4:3 / 3:4 / 16:9 / 9:16), or click "Auto Trim" to detect the content bounding box in one click and cut away solid-color borders. Apply to crop; press Esc to cancel
• Rotate — rotate the whole image 90° clockwise / counter-clockwise, with annotations following along
• Flip — mirror horizontally / vertically
• Resize — enter target dimensions in a dialog with locked-aspect linking, plus 50% / 75% / 100% / 150% / 200% percentage presets; the base image is resampled at high quality
• Smart Background Transparency — one click auto-detects the background color along the four edges (white, black or any solid color) and clears only the background connected to the borders, leaving white text and blocks inside the image untouched; edges are anti-alias feathered to remove the halo left by rounded corners and diagonals, so the exported PNG has clean edges

Auto Trim and background transparency share a single background tolerance: drag the slider (0–128, default 16) in the "Image Processing" area of the properties panel — shown when nothing is selected — to tune sensitivity. Raise it when the background is impure or gradient, lower it to preserve detail more precisely. Transparent areas are shown on a checkerboard and exported as true transparency.

Properties & Layers

The properties panel on the right (a drawer on narrow windows) has two parts:

• Style properties — color, custom color, fill color, opacity, stroke width; the Text tool exposes font size, rectangles expose corner radius, mosaic exposes block size and arrows expose arrow size. With an existing object selected, changes apply directly to it
• Object operations — duplicate, delete, bring to front, send to back
• Image processing — when nothing is selected, a background-tolerance slider (0–128) shared by Auto Trim and Smart Background Transparency

The layers list at the bottom of the panel shows every annotation on the image (in stacking order) and supports:

• Toggling visibility of individual layers (temporarily hide an annotation)
• Moving layers up / down to adjust stacking order

Viewing & Navigation

• Zoom — the bottom bar provides zoom in / zoom out buttons, plus two presets: "Fit to Screen" (Ctrl+0) and "Actual Size" (Ctrl+1)
• Pan — with the Select tool, hold Space and drag to inspect details of large images
• Undo / redo — Ctrl+Z / Ctrl+Y, covering drawing, moving, deletion and property changes alike
• The bottom bar shows the current zoom level and image dimensions in real time

Saving & Sharing

• Copy to clipboard (Ctrl+Shift+C) — copies the edited result as an image you can paste anywhere that accepts images; the button briefly shows a "Copied" confirmation
• Save (Ctrl+S) — overwrites the original file path; images without a file yet (e.g. screenshots) fall back to "Save As"
• Save As (Ctrl+Shift+S) — save a copy to a new path with a new name

Images opened through the Launcher are edited in place: Save overwrites the original file instead of producing a copy — exactly what "quick fix" should feel like.

Image Info & EXIF

The "Info" button on the bottom bar opens the image info panel with two kinds of data:

• Basic info — format, file size, resolution, color type, bit depth, bits per pixel, alpha channel, DPI
• EXIF data (when the photo carries it) — manufacturer, model, lens, capture time, ISO, exposure time, aperture, focal length and 35mm-equivalent focal length, exposure program, metering mode, flash, white balance, color space, GPS coordinates and altitude, software, author, copyright and more

Handy whenever you need to answer "when was this photo taken, and with what device?".
