Qimage Ultimate 2020.114 With Crack Download [Latest]
Jason Ramgel
I figured it out in the end, using a manually allocated buffer, which isn't very clean C++ code but works faster and without deprecated calls. It's not possible to pass image.bits directly to sws_scale because QImages are minimum 32 bit aligned ( -5/qimage.html#scanLine), meaning that depending on the image width, there is "empty space" in memory at the end of each line, which sws_scale does not skip/take into account. It's too bad because we now have two memory copying operations, in sws_scale and memcpy, instead of one, but I have not found a better way.
I still have a problem with the buffer allocation size, needing at least 64 extra bytes for no reason that I can make sense of, but otherwise we sometimes got segmentation faults. It might be due to how memcpy works, copying entire 32 or 64 byte blocks... But anyways here's the new implementation :
The rect() function returns the image's enclosing rectangle. The valid() function tells if a given pair of coordinates is within this rectangle. The offset() function returns the number of pixels by which the image is intended to be offset by when positioned relative to other images, which also can be manipulated using the setOffset() function.
QImage also provide the scanLine() function which returns a pointer to the pixel data at the scanline with the given index, and the bits() function which returns a pointer to the first pixel data (this is equivalent to scanLine(0)).
Monochrome images are stored using 1-bit indexes into a color table with at most two colors. There are two different types of monochrome images: big endian (MSB first) or little endian (LSB first) bit order.
The transformed() function returns a copy of the image that is transformed with the given transformation matrix and transformation mode: Internally, the transformation matrix is adjusted to compensate for unwanted translation, i.e. transformed() returns the smallest image containing all transformed points of the original image. The static trueMatrix() function returns the actual matrix used for transforming the image.
Constructs an image with the given width, height and format, that uses an existing memory buffer, data. The width and height must be specified in pixels, data must be 32-bit aligned, and each scanline of data in the image must also be 32-bit aligned.
The buffer must remain valid throughout the life of the QImage and all copies that have not been modified or otherwise detached from the original buffer. The image does not delete the buffer at destruction. You can provide a function pointer cleanupFunction along with an extra pointer cleanupInfo that will be called when the last copy is destroyed.
Constructs an image with the given width, height and format, that uses an existing read-only memory buffer, data. The width and height must be specified in pixels, data must be 32-bit aligned, and each scanline of data in the image must also be 32-bit aligned.
Unlike the similar QImage constructor that takes a non-const data buffer, this version will never alter the contents of the buffer. For example, calling QImage::bits() will return a deep copy of the image, rather than the buffer passed to the constructor. This allows for the efficiency of constructing a QImage from raw data, without the possibility of the raw data being changed.
Constructs an image with the given width, height and format, that uses an existing memory buffer, data. The width and height must be specified in pixels. bytesPerLine specifies the number of bytes per line (stride).
In areas beyond this image, pixels are set to 0. For 32-bit RGB images, this means black; for 32-bit ARGB images, this means transparent black; for 8-bit images, this means the color with index 0 in the color table which can be anything; for 1-bit images, this means Qt::color0.
If the depth of this image is 1, only the lowest bit is used. If you say fill(0), fill(2), etc., the image is filled with 0s. If you say fill(1), fill(3), etc., the image is filled with 1s. If the depth is 8, the lowest 8 bits are used and if the depth is 16 the lowest 16 bits are used.
Inverting an 8-bit image means to replace all pixels using color index i with a pixel using color index 255 minus i. The same is the case for a 1-bit image. Note that the color table is not changed.
This function can be used to change images with alpha-channels to their corresponding opaque formats if the data is known to be opaque-only, or to change the format of a given image buffer before overwriting it with new data.
Warning: The function does not check if the image data is valid in the new format and will still return true if the depths are compatible. Operations on an image with invalid data are undefined.
Saves the image to the file with the given fileName, using the given image file format and quality factor. If format is nullptr, QImage will attempt to guess the format by looking at fileName's suffix.
Together with dotsPerMeterY(), this number defines the intended scale and aspect ratio of the image, and determines the scale at which QPainter will draw graphics on the image. It does not change the scale or aspect ratio of the image when it is rendered on other paint devices.
Together with dotsPerMeterX(), this number defines the intended scale and aspect ratio of the image, and determines the scale at which QPainter will draw graphics on the image. It does not change the scale or aspect ratio of the image when it is rendered on other paint devices.
Warning: This function is expensive due to the call of the internal detach() function called within; if performance is a concern, we recommend the use of scanLine() or bits() to access pixel data directly.
The returned image will normally have the same Image Formatsformat as the original image. However, a complex transformation may result in an image where not all pixels are covered by the transformed pixels of the original image. In such cases, those background pixels will be assigned a transparent color value, and the transformed image will be given a format with an alpha channel, even if the original image did not have that.

Just for fun, just try to print a large print ( PHOTO ONLY ) from a PSD or JPG file stright to your 4900 using QIMAGE. Same size, resolution, as the files that have been giving you problems all this time. Don't send it anything that was created in InDesign but in photoshop instead. I thought Indesign needed postscript based printer. I am not really that familiar with the Indesign as I don't really create anything for publication but I supposed converting to PDF takes care of that anyway. I am just curious if it isn't file or source specific.
