[email protected] changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] Status|REPORTED |CONFIRMED Ever confirmed|0 |1 --- Comment #1 from [email protected] --- Hi, I think I am experiencing the same problem. I'm using Krita Portable for Windows, version 5.2.15 This issue does not seem limited to the "eraser" brush tool, it also applies when using the Elliptical Selection Tool to cut and paste parts of an image between layers. STEPS TO REPRODUCE: 1. Open a JPEG image stored on the computer as a new image. 2. use the Elliptical Selection Tool to select a circular part of the image. 3. Cut out the circle by hitting Ctrl+X. 4. Paste the image with Ctrl+V. This will automatically create a new raster layer. 5. Right click the **original layer** and choose "Remove Layer", this will leave you with a circular image with transparency around it. 6. Save the image as a .PNG. (settings are Compression 9, Interlacing on, Save as HDR off, Embed sRGB profile on, Force convert to sRGB on, Store alpha channel (transparency) on, Store Metadata off, Sign with author data off, and Force convert to 8 bits/channel off. Transparency color is set to whatever the default is, and Also save your image as a Krita file is off. 7. Open your image in another program, in my case SOLIDWORKS 2023. Solidworks defaults to a Transparency mode "None", which the working theory is it ignores all Alpha channel Data. This makes the ***original image appear in SOLIDWORKS, as if you had never edited it at all***. The option "From File" causes SOLIDWORKS to respect the Alpha data and shows the image as a circle. I can also confirm the issue with the Eraser Brush brush tool still persists in 5.2.15 since I tested that with a squiggle and it also didn't actually "erase" that part of the image. I consider this to be a pretty severe problem because someone using Krita might think to use the "Eraser" for security or privacy purposes when in fact the erased part of the image is recoverable even after exporting as a different file format. I agree with madmrmax that this seems to be an issue of Krita setting the alpha channel to zero when it should really be setting all channels to zero. But this seems to affect many, if not all, Krita operations. I am setting this bug's status to CONFIRMED and am open to do further testing in the future. I was using Krita on a work computer running Windows 11 and SOLIDWORKS is the only way I can "ignore" the alpha layer data of the image, but if anyone needs me to do more professional testing, including uploading files, I can do so. -- You are receiving this mail because: You are watching all bug changes.
