Png Image 4 Channels. Tiff also offers the explicit possibility of treating a subfile or secondary image within the file as a transparency mask though such masks are only 1 bit deep and therefore. Is there a more elegant way to do that.
I want to reduce its channel count from 4 to 3. Specified by a constant. I found that just removing 4th channel is unsufficcient.
If mode of the original image is rgb 8 bit x 3.
Is there a more elegant way to do that. How to set transparent background to grabcut output image in opencv c. How to use image putalpha the parameter of putalpha is only alpha as it is literally put the alpha channel layer to the original image. Tiff also offers the explicit possibility of treating a subfile or secondary image within the file as a transparency mask though such masks are only 1 bit deep and therefore.
