I am editing a JPG image (of an scanned old photograph) which has many artifacts. I'm mostly using the Clone tool and for safety I save the file every time I make one single change in the image. The problem is, the Export to JPEG dialog box appears whenever I save the file, and it's very annoying because I have to close it a lot of times to continue my work.
Is there a way to disable this dialog box? TIA.
Well, fellows, I thank you so much for your answers and thoughts on the matter. As I said before, I was only using that particular JPG image due to limitations of my MFP's scanner, which had only JPEG as output option at the time.But I still need an answer for my original question. Or that is a behavior that can't be changed in Photo-Paint unless the developers change it?

I don't think that they should change it.
Saving to a format that uses lossy compression is really an "export" process - because it is creating an image that is different from the one that you are editing. You really don't want to repeat that process again, and again, and again - every time you save during the editing process.
Again, if you must start with a .JPG, it's a good strategy to start by saving it in some format that does not use lossy compression, and to keep it in such a format throughout the editing process.
From that format, you can always export to .JPG later if you need to. When doing so, you will have the opportunity to choose compression settings to find the compromise between quality and image size that best suits the intended use of the image.
Don't throw away image quality until you have to.
OK, but I still can't see why show that dialog box every time I save the image after changes. I don't get the concept of "creating an image that is different from the one that you are editing". I think I am not creating a new image, I am editing an image, and then I can save it as a new one if I want to. And why the same behavior doesn't apply when I edit a TIF image? If it's about the lossy or lossless thing, why the same happens when I edit a PNG image?I'm thinking about IrfanView, a small image viewer with basic edting capabilities that has this IrfanPaint plug-in, which adds some more editing tools, Clone included. If I edit JPG images using both and save changes lots of times, I get no Save or Save as dialog. With IrfanView alone I can rotate, resize, apply filters, etc. Only when I use the IrfanPaint and save the image the plug-in box is closed, but then I hit F12 to reopen it.Anyway, I think it would be great if Corel added an option to not show that dialog in that scenario, just like I can choose not to show the filter dialog when I export files.
"Creating an image that is different from the one you are editing" means that every time you export or "save" your image as a JPG, the software actually makes a whole new file of that image, but at a lower quality. That lower quality image file is now what you are working on. When you export that image as a JPG to "save" your work, the quality of the image goes down even more.
Each pixel in an image is information. TIFF and CPT both preserve all of that information. Exporting to JPG will discard some of that information permanently to reduce the size of the file. This happens every time you do save as a JPG- more and more of the information is discarded, degrading the image quality each time. THIS is why the dialog box pops up every time. Think of it as a safety feature asking you if you are sure you want to end up with a degraded image.
Your scanned image starts as a JPG. After you open it, immediately save it as a TIFF or CPT to ensure that you are saving the best possible version of the image with all of its "information" intact. You don't have to actually interrupt your workflow to manually save your work! You can have the program do this for you automatically.
Go to "Tools", then "Options", then "Save". You can set it to automatically save as often as you like. For instance, you could have it save your work every 7 minutes, so you won't lose the progress you've made. Do not export your image as a JPG unless you have to make the file size smaller. Save your work as TIFF files. The CPT format is useful if you are working with layers; it preserves each layer, whereas a TIFF will flatten the layers.
