I have read previous posts about people explaining why they get black image when trying to display their image files. But none of them helped me out, because I believe I have a problem with my source file (or reading it) in the first place and I cannot figure out what.
The story is that I have a set stimuli that I created on Inkscape and saved them as PNG files (all of them black lines on white background in 500x500px). This is how I try to display them (at least one of them) and get a black image:
When I look at the way that the file is arrayed, I could get the following information:
More information on the PNG file:
I do not think that my problem is related to image type or how I display them (as opposed to other previous posts). I have also tried converting my PNG files into BMP files and they seem to be working just fine (although a few artifacts are visible due to conversion). I feel like I have something wrong with my PNG files (resolutionunit in meters seems somehow suspicious), but I cannot figure out what and wonder if I am missing something else here.
I would be really pleased if you could help me figure this out.
