This original technical example tests a saved raster preview. It is not native CorelDRAW artwork. Open the CDR viewer and select technical-preview-2025.cdr. Inspection detects version 2700, labelled 2025. The verified rendering result uses the embedded engine: one raster preview, no editable vectors. Compare the image and resolution. The sample preview is 960 by 600 pixels; zoom does not create extra detail. Full format conversion of this recent CDR is refused as conversion_unavailable. Ask the author for a native PDF when needed. Download the public fixture and verification record from the compatibility table. Test your own document separately.
