GIMP comes with standard filters that supports creating gradients; look under Filters+Light After you’re done with your image, you can export it in PNG format. One of the most common uses for GIMP, is to prepare images for web sites. To export an image with transparent areas that do not have a soft transition. Most of the file formats that GIMP can open, can also be used for saving. Exporting an image does not modify the image itself, so you do not lose anything by.

There are situations, however, in which using no subsampling 4: You can select among three options:. Frame disposal when unspecified Frame disposal when unspecified: Viewers on other computers can then compensate to ensure that the image ekspor not too dark or too bright.
Saving Images with Transparency 2. But your image becomes somewhat blurred. Unfortunately, PNG offset support in GIMP is broken, or at least is not compatible with other applications, and has been for a long time.
The float method is very slightly more accurate than the integer method, but is much slower unless your machine has very fast floating-point hardware. Commonly referred to as 4: If the image has a soft transition into the transparent areas, you should not remove the alpha channel, since the information used for the transition is not be saved in the file.
The GIF file format does not support some basic image properties such as dksport resolution. Preparing your Images for the Web. By using this option, you rksport smooth the image when saving, reducing them.
Save background color Save background color: This is the standard subsampling, which usually provides a good ratio between image quality and file size. Also note that the results of the floating-point method may vary slightly across machines, while the integer methods should give the same results everywhere.
Please note, that this is not necessary for InternetExplorer 7 and above.

Not all file types are equally good for all purposes. The default quality of 85 usually produces excellent co, but in many cases it is possible to set the quality substantially lower without noticably degrading the image.
It is important to realize that the only format capable of saving all of the information in an image, including layers, transparency, etc.
JPEG files usually have an extension. When you save a file in JPEG format, a dialog is displayed that allows you to set the Quality level, which ranges from 0 to Delay between frames where unspecified You can set the delay, in milliseconds, between frames if it has not been set before.
There are two different approaches used by graphic file formats for supporting transparent image areas: The result is typically a smaller file, but it takes more time to generate.
Saving an image in any file format will cause the image to be considered “not dirty”, even if the file format does not represent all of the information from the image. A PackBits data stream consists of packets of one byte of header followed by data.
To demonstrate the capabilities of alpha transparency, a soft glow in the background around Wilber is shown. The GIMP is capable of reading and writing a large variety of graphics file formats. Three methods are available:. Images with layers are flattenned before saving to PNG and layer offset is taken in account. No other format comes close to achieving the same level igmp compression.
The fast integer method is much less accurate than the other two.
Saving Images with Transparency
It does not, however, support transparency or multiple layers. The emsport can open PDF documents consisting of a single page or multiple pages, and while it doesn’t support multi-page PDF exports, it does let you export each page individually.
In this text box, you can enter a comment which is saved with the image. This option give you the opportunity to choose the compression method that is appropriate for your image:. After you have flattened the image, export the image in the PNG format for your web site.
EXIF data provides information about the image such as camera make and model, image size, image date, etc. In fact, it is often a good idea to save at intermediate stages too: When this option is checked, the color values are saved even if the pixels are completely transparent.
GIMP: Saver and Save/export clean plug-ins
Exporting an image does not modify the image itself, so you do not lose anything by doing this. You can read this comment in the Image Properties.
The EXIF data is not altered in any way when you do this. Compression level Since compression is not lossy, the only reason to use a compression level less than 9, is if it takes too long to compress a file on a slow computer. If this has not been set before, you can set how frames will be superimposed.
With this option enabled the compression of the image will be inserted progressively in the file.
