New costume downscaling

whenever making a costume with the new costume block, it’s size is automatically clamped to whatever fits in the stage.
i could change the stage size, but it’s slightly unfeasible for the behavior I actually want considering the images can be (almost) any arbitrary size.

in this example, width and height are both 528, and final is a 278784 long pixel list. i also tried a 528x528 table of colors, yet the size was also clamped.

is there any way to not have the clamping take place without resizing the stage?

i also tried using the stretch costume block, which ultimately did actually upscale the costume past what the stage allows, but this still won’t work because of loss of detail in the initial downscaling.

bump!

still need some help here as my only compromise currently is using JS to construct the full-size image and then downloading it

the issue isn’t an existing costume, it’s trying to make a new costume and it gets automatically downscaled to fit the stage.
and also,

try this

Costume.prototype.maxDimensions = new Point(Infinity, Infinity);

this works for now, but if someone can find a solution without JS, that would be appreciated!
