how to do image clipping mask for rentry:
- save your image mask via pinterest or resource page, and the image you want for your rentry
- open ibispaint x and import the image mask
- select the magic wand tool and select the background on the image mask (or everywhere you don't want the image to show)
- select the eraser tool and erase everything
- go to selection layer (top in the layer page) and remove selection
optional: blur the image mask a bit if it is pixelated - add your image in, adjust the position, then make the layer a clipping layer, then merge the layers
- add any additional pngs/text or edits
- save as a transparent png (this is important!)
