Poor image quality when uploading an image with Rise
- 6 years ago
Hi everyone!
Do you have an image that looks blurry in Rise 360? We've designed a workaround to keep your images looking crystal clear.
If you'd like an image to keep its specific file format and not undergo compression, you can opt-out of image optimization on a case-by-case basis. Add _NOPROCESS_ to the name of your image file. It'll upload and display exactly as you saved it. Keep in mind that the 5GB file size limit still applies, and you could see an increase in your output file size.
DPI (dots per inch) or PPI (pixels per inch) won't change anything for images displayed on screen. DPI is print resolution. It's an instruction for printers and it affects only printed images or images displayed in presention software like PowerPoint. Web browsers don't understand DPI or PPI.
What matters for on screen images is dimensions in pixels (width and height) and compression. JPG images can look very bad with heavy compression. But the PNG format has lossless compression so images shouldn't have any artefacts or loss of sharpness.
Articulate must be applying some type of compression after uploading to Rise because, while PNG images are still in PNG format, their size after export is much smaller than the originals. For example, I uploaded a PNG image with a file size of 132 KB. After exporting the course for web, the same image in the assets folder is only 41KB and shows signs of lossy compression.
Yes, I know. However, this is the *best* way I could find to fix the issues with my projects. So perhaps take the DPI as a YMMV type thing. :) Thanks!
