901174 - Image incorrectly loaded and rendered in canvas

Status: RESOLVED INVALID

(Core :: Graphics: Canvas2D, defect)

Description

[Alon Zakai (:azakai)]

Attachment: case.zip

The attached testcase loads a png image, then renders it into a canvas.

The image should be a red triangle, 255,0,0 in each pixel. However, on one of my two machines, on firefox (but not chrome), the triangle is rendered as a less saturated red. Running the testcase there, it reports 219 instead of 255, and you can also visually see that it is not 100% saturated as it should be.

This is breaking many things in the emscripten test suite, which relies on loading images and reftesting them against something that was just rendered.

I guess this is a png color correction issue.
