Michele Balistreri commented on PDFBOX-3305:
--------------------------------------------
I know matrixes are concatenated, but if I want to put a single matrix that
does all I need, it should be easy to do so. I do not understand the problem
with images appearing exactly at the same position. If alpha is less than 1.0,
it can very much make sense.
Having a method which does only one thing (draw the image) instead of also
forcing a matrix seems logical to me. I am currently forced to use the
deprecated drawXObject method, but I would like to avoid using deprecated
methods.
> PDPageContentStream should allow drawing images at current position

> Project: PDFBox
> Issue Type: Improvement
> Components: PDModel
> Affects Versions: 2.0.0
> Reporter: Michele Balistreri
> Priority: Minor
> Attachments: pdpagecontentstream-drawimage.diff

>
> The PDPageContentStream class has two drawImage methods (one calling the
> other) but both add a transformation to the graphics state. This patch adds a
> drawImage method with a single parameter (the image), which only adds the
> image without applying any transformation.
> This is needed because otherwise there is no other way of setting a transform
> matrix manually which might have skew/rotation in addition to
> scaling/translation.
> An alternative to this patch could also be a drawImage method which takes a
> Matrix and applies it. But still if for whatever reasons multiple images
> should be drawn with the same transformation matrix this would be inflexible.
