Scenarios to test

Upload

• Dropzone visible on load
• Uploading a PNG loads the image
• Uploading a JPEG loads the image
• The left panel shows the original image and the right panel shows the SVG output

Tracing output

• An SVG element appears in the right panel after upload
• The SVG visually resembles the input image
• The palette swatches are extracted and displayed

Quality / color presets

• Quality or color count presets are visible (e.g. 8, 16, 32, 64 colors)
• Selecting a higher color count produces a more detailed SVG
• Selecting a lower color count produces a simpler SVG with fewer paths
• Switching presets updates the SVG output without crashing

Simplification

• A simplification slider or preset is present
• Increasing simplification reduces the number of SVG path nodes/complexity

Flip transforms

• "Flip horizontal" button mirrors the SVG horizontally
• "Flip vertical" button mirrors the SVG vertically

Crop within SVG tool

• A crop tool is accessible from the action bar
• Selecting the crop tool shows a crop overlay on the canvas
• Applying the crop updates the SVG output to the cropped region
• Cropping the full image (no real crop) shows an informational message rather than silently failing

Color picker (eyedropper)

• Selecting a palette color with the eyedropper tool changes the selected color
• Changing a palette color updates the SVG paths of that color

Download

• "Download SVG" downloads a .svg file
• "Download PNG" downloads a .png file
• The downloaded PNG reflects the current SVG state (including any filters or crops applied)

Acceptance criteria

• SVG output renders after upload
• All preset changes re-render the SVG
• Both SVG and PNG downloads succeed
