Bug 5051 – PDFs in HTML pages do not scale

• Component: PDF
• Status: RESOLVED FIXED

[Mac-arena the Bored Zo]

when the HTML specifies the width and/or height of an img that is a PDF, the image is cropped rather than 
scaled. (will attach an example.)

Example of bug.

a PDF which is 3.5 cm square, shown on the page at 1x and at 5x. instead of
scaling the second img to 5x, it simply crops it to this size (showing the PDF
at 1x magnification in the lower left of a 5x box).

[Andre-John Mas]

Observations:
  -  nightly build of 2006-02-11 does not even show the PDFs, instead showing the broken image symbol, while release version 2.0.3 does.
  -  in Safari 2.0.3 images are misaligned, but not in TextEdit
  -  both TextEdit and Safari show images at the same size without the scaling being applied.
  -  is PDF even considered a web-standard image and would an embed not be more suitable for the data type?

BTW would it be possible to save test cases at .zip, so they can be easily be tested with non-webkit based browsers for behaviour comparison?

I'm not sure, but with PostScript support recently added (Bug 3527), I wonder if inline PostScript would work as well once this is fixed?

If you're asking for a new feature in WebKit similar to Firefox's "Save Web Page (Complete)", I would suggest filing a new bug (with a severity of "enhancement").  Otherwise you'll have to use Firefox today to save the web page that way, then zip it up and post it to this bug.

Confirming bug on Safari 2.0.3 (417.8) on Mac OS X 10.4.4.

See Bug 7206 for a regression that must be fixed before this one may be fixed.

See Bug 7211.

Upping to P1 since the PDF no longer renders and used to.

Without a working example, I'm not sure what to do here.  The attached sample doesn't work.

The comments suggest this bug is present in Safari 2.0.x, which indicates this is not a regression.

a working example of the bug

[Frances Cornwall]

It looks like CSP is blocking inline styles that the PDF Plugin is trying to load in Safari 17.4.1.

The bug is not in the mini-browser.

It looks like it was fixed by: https://github.com/WebKit/WebKit/pull/27271 and related to bug: https://bugs.webkit.org/show_bug.cgi?id=272689.

The PDF Plugin is now not able to scroll in the mini-browser.

@brandon, do you think this is a duplicate of Bug 272689

[Brandon]

@karl My PDF fix did not fully resolve this issue. The sizing is correct, but the PDF is still not loading with my change (checked in mini browser).

[Brandon]

Downloaded the latest build from https://webkit.org/build-archives/#mac-sonoma-x86_64%20arm64 and the issue doesn't reproduce for me now.

[Brandon]

This should probably be marked as fixed. It was fixed in https://github.com/WebKit/WebKit/pull/27271
