There are two fast ways for down-converting high color images: Just choose the nearest palette color (creates awful banding) and dithering with a regular pattern derived from the low bit(s) of the X/Y coordinate values (generates annoying patterns). In case you want to display multiple arbitrary images at a time, you can not optimize the palette to specific images, but you would need to settle on a common palette for all images. Properly choosing the palette color immensely reduces the amount of color errors you had to conceal. If you want to display only a single image at a time, you can create a palette adapted to that image. There are two key points to generating good looking 256-color images: Choosing a proper palette and obscuring color errors (usually by some kind of dithering). They have to have been taken at a higher bit depth and downleveled to 8 bit what happened? Why are the converters immediately at our fingertips so bad and how could they be good? The images could not have been taken with an 8 bit camera. The images are reasonable much better than someone dealing with 16 bit to 8 bit conversion would expect.
#GRAPHICCONVERTER EXPORT 16 COLORS PC#
This is not rose colored glasses-my multimedia PC era CDs are still readable and I called one up to verify. But neither the videos nor the images are the terrible of reducing 16 bit depth to 8 bit depth. Granted, they show so many artifacts now that the videos look bad to modern eyes. I used to painstakingly hand-construct 256 color images.īut we had these encyclopedia and other programs that had 256 color images and videos that were awesome at the time. You had to be a really good programmer to make it come out well because of palette control (and the background program always went to trash) but it worked. It was the same in the late 90s when I had access to 16 bit depth converting to 8 bit depth was terrible.īut I remember the days of the Multimedia PC and S3 cards and 8 bit depth. This way you avoid unnecessary quality losses with formats like the JPG or the HEIC format.If I take a 24 bit image and reduce it to 8 bits with save as of any simple drawing, the result is terrible as any modern computer user would know. If you have only changed the IPTC/XMP metadata, you can now save these changes without resaving the entire file. GraphicConverter does the conversion and performs an action at the same time if you wish. Drag your images onto the dialog and sit back. Our new dialog makes quick conversions even easier. This makes it easier for you to orientate yourself while working.
Crosshairs In order to be able to read the mouse position at any time during editing, a crosshair can be switched on in the settings, whose lines always go to the edge of the image.HEIC images can now be saved with GainMap gain data. In Convert & Modify, you can now save your regularly used folders as favorites. If you move to a different or new Mac, you can now easily take all settings and saved actions, etc. A new feature is that the torn-off part is moved to the right so that you can position it freely. GraphicConverter tears off the lower part and adds a shadow. Simply draw a zigzag line with the mouse. If you don't want to show an image in its entirety, for example, because of space limitations, you can make the edge look like it's been torn off. Save your image in GraphicConverter format /gcimgd) to be able to change the vector objects later. Many have been waiting for this: lines, circles and rectangles can now be created as vector objects, optionally with a shadow. Just like on iPhones and iPads, you can now automatically crop people and objects and insert them into another image, for example. This means that there is no loss of quality with compressed formats such as JPG and HEIC, and RAW images can also be edited. Your advantage: You can, for example, delete parts of the metadata such as exposure time and aperture in one editing step and copy the contents of an IPTC field into another field, etc. With the new Metadata Juggler dialog you can effortlessly combine several editing steps, save them and open them again at any time, just as you already know from the actions. With GraphicConverter you have always been able to edit the metadata of your images and move them to other fields.
