I want to add the following example:
# 1
using TestImages
testimage("mandrill")
# 2 using Images, TestImages
testimage("mandrill")
The first code snippet crashed Juypter, the second one runs fine. The reason is, that testimage("mandrill")
returns a 512x512 Matrix of RGB values (which are defined in Colors.jl
). Without importing Images.jl
, Julia will try to render this matrix as an SVG picture.
from colors.jl.
The following is not a drastic solution but one of the mitigation measures:
master...kimikage:display(rewrited. see below)
It is easy to limit the matrix size.
However, I don't think it is a simple matter to decide what should be displayed.
Top left corner? Four corners? Decimation?
By the way, I found a little bug (#341).
Edit:
I implemented the decimation style.
master...kimikage:display2 PR #346
The decimated image is displayed like a comb in a purposeful manner to specify that it is decimated.
displaying a 1000-point vector in an SVG in IJulia bricks the computer.
In the proposed implementation, at most 16384(=128*128) points are displayed.
from colors.jl.

Another reduction method was implemented: #346 (comment)
from colors.jl.
