TypeError while attempting to load a specific 3D Image from a base64 #140

Closed Cereser01 closed 1 year ago

Cereser01 commented 1 year ago

Hello, I am experiencing errors while attempting to load a specific base64 3D Image through the following construction:

< x3d-canvas id="3dgraphicimg" src="data:model/+vrml;base64,I1ZSTUwgVjIuMC[...]Qp9DQo=" class="" > < /x3d-canvas >

(full content of the src attribute available in attached "error_src.txt" file) error_src.txt

The following errors pop up in console:

Notably, other 3D Images loaded through the same method work just fine. See "work_just_fine_src.txt" for the content of the src attribute of an image that does not generate the error. Additionally, both images generate without issues in a separate application that does not rely on the base64 method. work_just_fine_src.txt

As it turns out your file contains a BOM (https://en.wikipedia.org/wiki/Byte_order_mark), which was not properly handled by X_ITE, but this is fixed now.

Version 8.11.7 is just released.

It did indeed solve the problem. Thank you so much for the quick assistance.
