QUESTION
I have the following code
...ANSWER
Answered 2021-Feb-16 at 17:13So as @tsecheukfung01 explained in the comments, all you have to do is create a type with the same name as the variable that refers to a class. After you have done this you will see an @typescript-eslint error (if you have @typescript-eslint in your project of course). Acording to the @typescript-eslint docs you should just use an eslint ignore line. The complete working code...
QUESTION
I have the following classes/interfaces:
...ANSWER
Answered 2020-Jul-18 at 22:03Variance is applied only to references types, see the docs:
- Variance applies only to reference types; if you specify a value type for a variant type parameter, that type parameter is invariant for the resulting constructed type.
So you will need to change Positionable
from struct to class, to make this cast work.
Also if you are planning to work Positionable
via interface take in account that it will be boxed.
QUESTION
I using interface delegation as described here. Is there a way to use this but override and explicitly call the super class (delegate)?
Something along these lines (does not compile):
...ANSWER
Answered 2018-Nov-13 at 12:26You can't access delegate
in that case. As workaround you can use next approach
QUESTION
I am using iText for Java (5.5.13) and I am experimenting with rotating PDFTemplates using the Image class. The problem is that I can't understand what iText is using for the origin when rotating the images (and I apologise in advance if I am being stupid).
Attached is the code I am using
- I create a PDFTemplate
- Fill it with some arbitrary colour
- Create an image from this template
- Rotate image 90 degrees
- Set absolute coords for the image
- Add to the writer
Repeat again with a second rectangle but this time rotated only 30 degrees.
Shouldn't there be a common origin between the two shapes?? (It looks like there is an unwanted translation too)

Your implicit assumption here seems to be that the template is first positioned and then rotated around some obvious special point, e.g. the lower left corner of the template.
This is not the case. Instead you can imagine that the template is rotated, then the bounding box (with edges parallel to the page edges) is determined, and the lower left corner of this bounding box is positioned at the coordinates you set using Image.setAbsolutePosition
.
This becomes more obvious by drawing more rectangles, e.g. for 0°, 15°, 30°, 45°, 60°, 75°, and 90°:
