Expand description
An error produced when using CustomCursor::from_rgba
with invalid arguments.
Variants§
TooLarge
Produced when the image dimensions are larger than MAX_CURSOR_SIZE
. This doesn’t
guarantee that the cursor will work, but should avoid many platform and device specific
limits.
ByteCountNotDivisibleBy4
Produced when the length of the rgba
argument isn’t divisible by 4, thus rgba
can’t be
safely interpreted as 32bpp RGBA pixels.
DimensionsVsPixelCount
Produced when the number of pixels (rgba.len() / 4
) isn’t equal to width * height
.
At least one of your arguments is incorrect.
HotspotOutOfBounds
Produced when the hotspot is outside the image bounds
