Mirco MirandaandAlbert Astals Cid f5a6de7280 Full range HDR support 
EXR, HDR, JXR and PFM formats support High Dynamic Range images (FP values grater than 1).

In summary, here is the list of changes:

    EXR, HDR, JXR and PFM: When working with FP formats, the clamp between 0 and 1 ​​is no longer done.
    EXR: Removed old SDR code and conversions. Due to the lack of a QImage Gray FP format, Gray images are output as RGB FP (recently added code for Qt 6.8 has been removed).
    PFM: Due to the lack of a QImage Gray FP format, Gray images are output as RGB FP.
    HDR: Added rotation and exposure support.

With this patch, EXR, JXR, HDR, PFM behave like Qt's TIFF plugin when working with FP images.

Mirco MirandaandAlbert Astals Cid b849e48ef4 Fixed wrong plugin options behaviour 
While working on MR !230 I noticed that the options read I entered into several plugins could not be read after reading the image.

**The patch fixes problems reading options in plugins and adds option checking in the readtest.cpp.**

In particular, the reading test does the following additional actions:
- reads options before reading the image;
- compare the options read with the options returned by the reader after reading the image;
- compares the format and size of the returned image with the format and size returned by the reader.
 2024-06-19 22:18:45 +00:00
Mirco MirandaandAlbert Astals Cid 81b7263d73 EXR: Full support for gray image/colorspace 
Starting with Qt 6.8, QColorSpace supports Gray and CMYK color profiles.

- On saving, grayscale images are converted to linear gray profile;
- On loading, a Grayscale image is stored in a QImage::Format_Grayscale16 instead a RGB one;
- ScanlineConverter class was updated to gray conversions.

Mirco MirandaandAlbert Astals Cid 63e21ee5f3 Disable JXR plugin due to crashes in JXRLIB 
I ran a simple fuzzer on all the plugins in the repo and the JXR one crashes every few seconds. I attach some files (I have many more) that cause the crashes. For the moment I think it's best to keep it deactivated.

The strange thing is that for the same plugin I had created the PR on oss-fuzz which ran locally for over an hour without problems. I'm a bit confused.

Mirco MirandaandAlbert Astals Cid 06f097046c PFM: Portable FloatMap read only support

Mirco MirandaandAlbert Astals Cid 863c424390 Sanity checks (fuzzer) 
I ran a stupid fuzzer on all the plugins in the repo and some plugins needs more sanity checks.

- RAS: fixed palette reading on corrupted files
- RGB: improved error detection on datastream

This patch improves the reading speed of some corrupted files and limit the maximum memory allocation of RAS palette.

Mirco MirandaandAlbert Astals Cid 4f61e3912c XCF: Increased maximum property size

Mirco MirandaandAlbert Astals Cid 4995c9cd15 PSD: support native CMYK introduced by Qt 6.8 
Qt 6.8 will introduce native support for the CMYK (8-bit) format.
With this patch you will finally be able to correctly see the colors of CMYK images with ICC profile.
The testing part has been updated with the addition of an (optional) json file for each image to test. Inside you enter which image to use depending on the Qt version.

In short:
- Added native CMYK suport to PSD reader
- CMYK with alpha is converted using QColorSpace in a RGBA image
- Read tests changed to use the correct comparison image based on the Qt version
- Fixed also XCF tests: now works with all Qt version (see also [QTBUG-120614](https://bugreports.qt.io/browse/QTBUG-120614))
- Work around for CCBUG: 468288

Mirco MirandaandAlbert Astals Cid 95ee381195 XCF: testcase update for fixed Qt

Mirco MirandaandAlbert Astals Cid 8e5951471d TGA: added options support 
- Added Size and Format options support
- Fixed a double image allocation when reading RGBA images (RGB was always allocated and then replaced by RGBA one)
- Fixed the code for sequential devices

The Size option is used by the KIO 5 thumbnailer to avoid to use too memory. A backport to KF5 would serve CCBUG: 413801 and CCBUG: 479612
