--------------------------------------
Summary: Could the new rendering method of PageDrawer be optional?
Key: PDFBOX-4928
URL: https://issues.apache.org/jira/browse/PDFBOX-4928
Project: PDFBox
Issue Type: Wish
Components: Rendering
Affects Versions: 2.0.20
Reporter: Christian Appl
This relates to {color:#008dde}PDFBOX-4516, PDFBOX-4527, PDFBOX-4815,
PDFBOX-4886, PDFBOX-4863
{color}{color:#008dde}{color:#172b4d}
I have tested the new prescaled rendering method for the
{color}{color}{color:#000000}org.apache.pdfbox.rendering.{color}{color:#008dde}{color:#172b4d}PageDrawer
with PDFBox:2.0.21-SNAPSHOT{color}{color} for different images, with different
resolutions, target image sizes etc. and compared the results to our old
expectations (pre 2.0.20). And I really like it!
However it seems to depend on the person's subjective perception (atleast for
my tested images), whether I like the old or the new results better. When
asking my colleagues, I heard arguments for both sides.
Therefore my question is: Could a RenderingHint be introduced to disable/enable
this separately and more intentionally, instead of assuming, that the scaling
method must always be applied for specific scaling factors?
This would allow users to select the scaling method according to their own
liking and needs.
I can not really find a crystal clear, objective answer, whether the one or the
other is "better", therefore I would prefer being able to de/activate it
according to my own judgement.
As far as I understand, the criterion ({color:#000000}scaleX {color}<
{color:#1750eb}0.5 {color}|| {color:#000000}scaleY {color}<
{color:#1750eb}0.5{color}) has been selected rather arbitrarily.( ? )
But what if I want to apply it even to images above those scaling factors?
What if I want to not apply it to images bellow those scaling factors?
What if I want to apply it to Image A, but not to Image C, for some unknown
reason?
