Hi g/g, hamoudoudou, Edit: Sorry Guys, I was thinking gimp when I wrote the following. 
Eraser is one of the 'paint tools' --same panel as paint-brush, airbrush, etc. Looks like a pink cube. As far as I know, to 'erase with transparency' actually requires: 1. open desired image. 2. Click New, Select "Advanced Options", Click 'Down-Arrow' next to "Fill With Background Color', Select "Transparency", Click OK. 3. On the Original Image, from the Paint-tool panel, select one of the 'Area Selection" tools, such as 'Rectangle Select'. Use it to Select the entire or a part of the original image. Select Copy. 4. In the New Image, Select paste. Save the New Image [under a new name]. Close the old image. 5. When you erase something from the new image, all that is left is the transparent background. Erasing has to be done before adding new layers. I'd be pleased to learn if there was an easier way. mikesLr |

Don's link in first post seems to be dead so made this versioon from Slackware - made in Puppy 4.31 so should work in old Pups upwards. https://archive.org/download/pup4.311glibc2.19palemoon2.794sserev1/mtpaint-3.40-i586-2.pet P.S. Finally got into the account have reuploaded it to make it easier, https://archive.org/download/pup4.311glibc2.19palemoon2.794sserev1/mtpaint-3.49.12.pet _________________ Puppy Linux Wiki: http://wikka.puppylinux.com/HomePage https://freemedia.neocities.org/ |

This is software necromancy.  The current version is 3.49.19: https://github.com/wjaguar/mtPaint/tree/master

Mmm true but there hasn't been a new Puppy version in some time I was trying to find a newer one even on pkgs.org they are still at 3.40. Don doesn't seem to be on the scene anymore. Latest found Slitaz version 3.49.14 works for me:) _________________ Puppy Linux Wiki: http://wikka.puppylinux.com/HomePage https://freemedia.neocities.org/ |

Technically, any mtPaint version should build OK on anything more recent than year 2008, given that one of my test systems is still Slackware 12.1.
And if it fails to build somewhere, report it as a bug and I'll fix it. |

I came across a very rare and obscure bug in mtpaint. It involves the different rendering engines that the 3d program BLENDER uses to display an image. You can read it here if you're interested. https://developer.blender.org/T72941 _____________________________________________ |

Wrong. The bug is in blender. Image format specs, when we lucked to have them, are meant to be read. Test suites, when we have such, are meant to be used. Image loaders written by left hind appendage without engaging the brain, are meant to be fixed. Let whoever is responsible for PNG loader in EEVEE, avail himself of this snippet of information: https://www.w3.org/TR/PNG/#11transinfo Apparently, color key transparency got ignored, instead of being converted into an alpha plane. Which is a bug. |

That is why I posted the bug in the blender forum. _______________________________________ Recent versions of Blender have supported drag and drop of images as well as setting up the nodes automatically for an alpha channel. Maybe they forgot the PNG format spec in this rare case of starting with a GIMP opaque document. _______________________________________________________ |

On observing the discussion "when a bug is a bug" there, maybe quoting me there in full was fitting. Even if one in three devs has proven himself capable of reading docs on his own.
After your scaring me with the dreaded "bug in mtpaint" phrase however, I did characterize the coding practices which produced Blender's PNG loader a bit too harshly. On actually looking at the code, the "left hind appendage" part does seem unwarranted as I've many times observed much worse. The "without engaging the brain" part stands, because see below.
Which is exactly why testsuites for image formats exist. When they exist. 
But in case of PNG, it luckily does: http://www.schaik.com/pngsuite/ Including a nice series of examples of kinds of transparency possible in PNGs: http://www.schaik.com/pngsuite/pngsuite_trn_png.html The worst and longest part of writing an image loader, is trawling the Internet in search of weirdest & nastiest example files to throw at it to test the corner cases. When you already have a testsuite ready to go, not using it is not thinking straight. |

Blender calls it a 'known issue' rather than a bug

I did a quick test build of mtpaint-3.49.25 using GTK3 Looks OK, but will probably stick with GTK2 build My DpupStretch personal remaster (both .iso and devx) is set up so I can compile for GTK3 (without the wayland dependency). I am using the "Ultimate Maia Violet" GTK3 theme and Adwaita icon theme (cut down a bit) for GTK3 programs In older Pups such as Wheezy, I compile libwebp from source and configure mtpaint with staticwebp
