![]() ![]() There are numerous other vector formats: CDR is the CorelDRAW native format and XAR is the Xara Xtreme native format, to name a couple. Line+spline as well as line only output modes. Some programs have difficulty reading DXF files with splines (curves), so the Desktop Edition supports The AI format is fairly widely supported, but is less ubiquitous than the EPS format, and most programs that read AI can also read EPS.Ī CAD format from Autodesk, used by CAD tools from many different vendors. You can use the Delete key to delete any unwanted vector lines. Create a ruler with Layer menu > Ruler/Frame > Ruler from vector. By using the Selection from Ruler command with a raster layer, you can fill in all closed vector lines at once. The native format of Adobe Illustrator is the AI format (Adobe Illustrator Artwork), a modified version of the older EPS format. Use Selection from Ruler to fill in all of the vector lines at once. Support for reading and editing PDF files is much more limited. Those tools work with any program that is able to print. (third party tools that perform the same task are also for sale). Further information on the SVG format may be found on the official SVG website.Īdobe's PDF format (Portable Document Format) is very widely used as a general purpose platform-independent document format.Īnd while it is not exclusively used as such, it is also a very good vector image format.Īdobe gives away the Acrobat PDF reader, but sells the tools required to create PDF files Inkscape and recent versions of Adobe IllustratorĪnd CorelDRAW have good support for reading and writing SVG. The W3C standard vector image format is called SVG (Scalable Vector Graphics). Ghostview can read it very well but does not have any editing capabilities. It is widely supported as an export format, but due to the complexity of the full format specification, not all programs that claim to support EPS are able to import all variants of it.Īdobe Illustrator and recent versions of CorelDRAW have very good support for reading and writing EPS. It is the standard interchange format in the print industry. In any case, all of the variants of BMP should be avoided when possible, as they use little to noĬompression and consequently have unnecessarily large file sizes.Īdobe's EPS format (Encapsulated PostScript) is perhaps the most common vector image format. Most modern image editing tools are able to read both. Own formats, both of which are called BMP. There are actually several BMP formats (BitMaP). Vector Magic recommends using the PNG format when storing logos as bitmaps. This format is widely supported by web browsers and image viewers/editors. The best of the lossless image formats is called PNG (Portable Network Graphics). They are more suitable for things like logos. These store an exact pixel-by-pixel representation of the image, but require more space. We do not recommend using JPEG files for rasterized vector art, as the compression artifacts substantially degrade the quality of the image near edges. It has excellent compression characteristics and has the nice feature that the user may specify what level of compression they desire, trading off fidelity for file size. One of the most widely-used image formats. They are also commonly used on the web to save bandwidth. They are best suited to photographs and other images where perfect accuracy is not important. ![]() These have smaller file sizes but do not store a perfect copy of the image. Some of the most common are: JPEG, PNG, GIF, BMP, and TIFF.īroadly speaking, they fall into two categories: Lossy formats Alternatively, you can simply zoom into the area you wish to see, and then in the Composer window click the save button and select to "Save current view of highlighted raster layer as a new IDRISI image".There is a large number of different bitmap formats. If your AOI is much smaller than your full original raster image, you can use the WINDOW module to extract a smaller subset of the clipped raster. ![]() Next, use the OVERLAY module to multiply the two images together. You should now have an image with values of 1 for all areas within your AOI and values of 0 for all areas outside your AOI.ģ. Convert your photo to a paint-by-number pattern 2) Color By Number unblocked an. Select to copy the spatial parameters from the raster you wish to clip.Ģ. You will be prompted to bring up the INITIAL module to create a blank raster. Convert the vector layer to raster using the RASTERVECTOR module.Ī.All values multiplied by 1 (inside your AOI) will remain the same, while all values multiplied by 0 (outside your AOI) will become background values. Then you will use the OVERLAY module to multiply your raster image and your mask image. To clip a raster using a vector layer, you will first need to convert the vector layer to raster, assigning a value of 0 to all cells outside of your area of interest (AOI) and a value of 1 to all cells inside your AOI, this is called a mask. ![]()
