The recent addition of support for multi-frame (non-animation) formats

Giuseppe D'Angelo 3fb3d95c33 Add support for CMYK file I/O in JPEG
JPEG part 6 defines CMYK support. This commit adds such support to the
JPEG plugin.

A *very* interesting discovery is the fact that Photoshop inverts the
meaning of the CMYK color channels when saving into JPEG: 0 means "full
ink", and 255 means "no ink". Most other image viewers/editors follow
the same interpretation, I imagine for compatibility.

But others, like Adobe Reader, don't (???) -- a PDF expects a DCT
encoding with 0 meaning "no ink". I am adding a SubType to the image I/O
handler to let the user choose what they want, defaulting to Photoshop
behavior.

Also, turns out that Qt was already loading CMYK files and converting
them to RGB. I don't think we should do automatic, lossy conversions (we
were not taking into account an eventual colorspace...), so I'm changing
that loading to yield a CMYK QImage.

Finally: save the colorspace, even if it's a CMYK image.

QColorSpace doesn't support anything but RGB matrix-based colorspaces.
Yet, it can load an arbitrary ICC profile, and will store it even if
it's unable to use it. We can use this fact to preserve the colorspace
embedded in CMYK images, or let users set an arbitrary ICC profile on
them through Qt APIs, and then saving the result in JPEG.
[ChangeLog][QtGui][JPEG] Added support for loading and saving of JPEG
files in 8-bit CMYK format. When loading a CMYK JPEG file, Qt used to
convert it automatically to a RGB image; now instead it's kept as-is.

Giuseppe D'Angelo 2a54229f90 GUI: add CMYK painting support
This commit adds a CMYK 8bpp format to QImage. The idea is to enable the
transport of CMYK images inside Qt, for instance to be loaded/saved from
files or painted on CMYK capable paint devices (e.g. PDF).

Also, rasterization support *from* a CMYK image is added (on top of a
RGB surface), as well as CMYK image scaling/conversion.

Conversion and rasterization between CMYK and RGB isn't particularly
optimized nor it honors any colorspaces yet. The overall idea is to
match 1:1 the existing behavior of CMYK QColor (which get naively
changed to RGB; there isn't colorspace support in QPainter yet).

There are no plans to add rasterization *towards* CMYK.

Image save/load in native CMYK formats will be added in future commits.

Shawn Rutledge 3f515fa7af QtIcoHandler::canRead(): avoid checking more than once
QtIcoHandler::canRead() calls ICOReader::canRead(), which assumes that
QIODevice::pos() is at the position where the .ico data starts (i.e.
pos() == 0 if this is a separate .ico file). But if an AnimatedImage in
Qt Quick opens an .ico file, canRead() gets called multiple times:
the first is when QQuickAnimatedImage::frameCount() eventually results
in QImageReaderPrivate::initHandler(); then ICOReader::readHeader()
is called, which moves the file position. The second time is when
QQuickAnimatedImage calls QMovie::isValid(). At that time,
QIODevice::pos() == 6: we need to avoid calling ICOReader::canRead()
because it's no longer at the start of the data.

Without this change, AnimatedImage reports "Error Reading Animated Image
File" and doesn't show anything.

The fix is to store the known-good state, the same way that
QTiffHandler::canRead() returns true if its d->tiff already exists
(TIFFClientOpen() succeeded).

The test checks that it's ok to call QMovie::frameCount() first and then
QMovie::isValid(). Calling frameCount() has the effect of moving
QIODevice::pos().

Shawn Rutledge 7c313f1865 QMovie non-anim: use QImageReader::imageCount but not nextImageDelay
Since 3f4d6279c4b0d04422efff478a5e2fb36259dbaa (khansen 2005) QMovie
calls QImageReader::read() until QImageReader::canRead() returns false.
That's apparently to support animated image formats in which the
frame count is not known at the beginnning (i.e. not specified in
the image format's metadata). But non-animated multi-frame formats
are expected to return valid values from QImageReader::imageCount();
and those also tend to keep returning true from canRead() regardless
of how many frames have been read (the interpretation of canRead()
is "does the file have the expected format?" rather than "are we
about to read too many frames?"). So, when a multi-frame image is abused
as an animation, QMovie was able to keep reading the same frame
repeatedly and pretend that the frame sequence goes on forever.
It also tended to read frames as fast as they could be decoded,
because nextImageDelay() is not usually provided, because multi-frame
image formats don't specify a frame rate in their metadata.

So now we change QMovie's behavior for image formats where
QImageIOHandler::supportsOption(Animation) returns false:
trust imageCount(), but not do not trust nextImageDelay().

But to actually jump to the next frame in this case, we also need to
call QImageReader::jumpToNextImage().

Altogether, this makes QMovie support "flipbook" animation for
multi-frame image formats, such as tiff and pdf.

Added "read frame x of c" logging in qt.gui.imageio category.

For testing, we use a pre-existing multi-frame Obj_N2_Internal_Mem.ico
file, to avoid depending on the tiff plugin.

[ChangeLog][QtGui][QMovie] QMovie now handles non-animated multi-frame
image formats (such as tiff): QImageIOHandler::imageCount() is observed,
and the default frame rate is 1 FPS.

Volker Hilsheimer 5f1fffc00e QIcon: add theme icon constants
Add a list of constant string literals for a subset of icons from the
freedesktop specification. Those are icons we document to support today,
and that users might have written themes for.

Omit icons that are mime types (we have Q(Abstract)FileIconProvider
and QPlatformTheme::fileIcon for that), the "flag-aa" icon (where 'aa'
is an ISO 3166 country code, and Face* icons. Flags and Face icons can
be added as supported QIcon constants, but should then be rendered as
emojis from the respective font (they are not provided by any of the
native icon libraries or icon fonts).

We use string constants instead of an enum so that we have the same code
path for icon constants, user-defined icons, and native icons. I.e. in
addition to QIcon::fromTheme(QIcon::ThemeIcon::EditCopy), code can
request the icon for "trash.circle.fill" on Apple platforms, or
or for U"\ue5cd" on platforms where the engine is font-based; or an app
can define their own icon name and provide the assets through a theme-
description, as before.

The downside is that we cannot use arrays for looking up the native icon
for an enum-value in the engine implementations, but given that icons
are cached this is an acceptable trade-off.

To make the list of icon contants more manageable, have them in a
separate header file. Since we want those constants to live in the QIcon
"namespace", we then include that header in a declaration of a nested
struct, "ThemeIcon", resulting in e.g. QIcon::ThemeIcon::EditCopy.

Volker Hilsheimer 76b58be4b8 QIcon: don't rely on getting a null-icon in test
If a QPA-provided engine provides an "edit-cut" icon, then it won't be
null. We cannot reliably test that the icon came from the fallback theme
as the cacheKey of the icon doesn't change (the proxying to a different
theme is handled internally by the QThemeIconEngine).

That the cacheKey of a QIcon doesn't change even if the pixmaps we get
from it change is not a problem in practice; QIcon is a named container
for  transient graphical assets that might change for reasons outside of
Qt's control (such as color scheme, or display resolution).

As a result of the fix for QTBUG-75214, Qt inadvertently no longer
reads the AND mask that specifies transparency for 16-bit and 24-bit

icoAttrib.depth == 32, but icoAttrib.depth is set to the depth of the
QImage, not the depth of the icon, and 32-bit QImage is used for all of
the non-indexed cases (16-bit, 24-bit and 32-bit.)

This commit instead uses icoAttrib.nbits, which should reliably
determine whether or not the icon is 32-bit. This makes the behavior
consistent with other ico reading software, including Windows.

generating new string keys for identical state, exposed this
misbehavior, and one way to fix the resulting issue for the user is to
make sure that QPixmapCache doesn't leak QString keys.

The Fusion style issue with generating non-repeating keys for use with
QPixmapCache should also be fixed, eventually, but this patch
relegates that to an optimization issue (the caching is effectively
non-existent), the resource exhaustion is gone now.

The issue exists because the QString keys are internally mapped to
QPixmapCache::Key's by way of a QHash<QString, Key> cacheKeys data
structure. When the QCache, indexed by Key, not QString, decides to
evict an entry, the Key is invalidated, but no-one was removing the
corresponding entry from cacheKeys. So make the existing releaseKey(),
used to invalidate copies of Keys referring to evicted pixmaps, do
that, now. So as not to have to scan the whole cacheKeys QHash for the
right Key, store the QString key, if any, inside the Key, so
releaseKey() can retrieve it and use it for O(1) erasure from
cacheKey.

This allows removing the previous work-around in clear()
(6ab0d25a09), greatly simplify
object(QString), and requires to rewrite all code that holds iterators
or references into cacheKeys over an insertion into or removal from
the QCache. Two (insert() and remove()) have already been done in
prequel commits, so only flushDetachedPixmaps() was left.

We still need to consult fallbackThemeName() when computing the

Tor Arne Vestbø f4dca7c512 Consult QIcon::fallbackThemeName() even for themes with explicit parents
We would previously only use the fallback theme for themes that did
not exist, or for themes that did not declare any parent theme.

We now unconditionally use the fallback theme, even for themes that
declare their own parent themes, so that a QIcon::fromTheme("foo")
that doesn't exist in the current theme, nor any of its parents,
nor in "hicolor", will still be looked up in the fallback theme.

The reason this seemed to work in the existing tests was because
our test themes inherit system themes such as crystalsvg and gnome,
and we didn't provide a hicolor theme. Any of these themes missing
would lead us into the code path where we use the fallback theme
for a missing theme, masking that fact that we had not added the
fallback theme to the list of fallbacks for the theme that had
explicit parents declared.

The logic has been moved out of the theme parsing and into an
accessor in QIconTheme, so that we're not caching the fallback
theme lookup.

used as fallback even for themes that declare a parent theme.

Marc Mutz 78cdd9a64d QPixmapCache: deprecate replace()
The replace() implementation overwrites the passed Key key with a new
version, const_cast'ing away the const from the key passed by
reference-to-const. This is UB if the Key was originally declared
const.

Deprecate the function.

Also inline the const_cast, so compilers can readily detect the UB
even if users don't enable deprecation warnings. Due to the severity
of the issue (UB), immediate deprecation is warranted. There appear to
be no in-tree user of the API outside of tst_qpixmapcache.cpp.

[ChangeLog][Deprecation Notice][QtGui][QPixmapCache] The `replace(key,
pixmap)` function has been deprecated, because passing a `const Key`
to it results in undefined behavior. Use `remove(key, pixmap)`
followed by `key = insert(pixmap)` instead.

Marc Mutz 0e96dd3464 tst_QPixmapCache: QVERIFY a failed replace()
Between the find() == 0 obfuscation (since fixed) and this unchecked
replace(), it took me way too much time to figure out what was going
on: the key passed has been invalidated by the setCacheLimit(0).

Now that we QVERIFY that the replace() _fails_, it's much easier to
backtrack and figure out why it does so and why, consequently, the
following find() is also expected to fail.

As a drive-by, reorder two lines so the grouping becomes clearer
(blocks now both headed by setCacheLimit()).

Marc Mutz 6ab0d25a09 QPixmapCache: fix leaking of QStrings and Keys on clear()
QPixmapCache maintains a mapping from QString to QPixmapCache::Key, in
the form of the cacheKeys QHash, but QPixmapCache::clear() didn't
touch it, leading to the string data (as well as the Keys) being
retained after any possible use. This can lead to memory slowly being
eaten up, as reported in QTBUG-112200, and prevents a periodic calling
of QPixmapCache::clear() from being a work-around for the issue in the
bug report.

Fix by clearing cacheKeys in QPixmapCache::clear().

This is designed as a low-risk enabler of a work-around, not a fix for
the issue. The work-around enabled by this is periodic calling of
QPixmapCache::clear().
