Navigate your file system to determine where to save the image file, and specify the name of the file. Choose the graphics file format you want to use from among the image file formats listed in the Files of Type menu. For more information about using the tool, see Tips. Use this syntax when you want to save an image whose parent is not the current figure. Process the image.

If you do not specify an extension, then saveas saves the figure to a FIG-file. To save the current figure, specify fig as gcf. If you do not specify a file extension in the file name, for example, 'myplot' , then the standard extension corresponding to the specified format automatically appends to the file name. If you specify a file extension, it does not have to match the format.

If the output file format does not support bit data, then imwrite returns an error. If A is a grayscale or RGB color image of data type double or single , then imwrite assumes that the dynamic range is [0, 1] and automatically scales the data by before writing it to the file as 8-bit values. If A is of data type logical , then imwrite assumes that the data is a binary image and writes it to the file with a bit depth of 1, if the format allows it. If A contains indexed image data, you should additionally specify the map input argument. If A is an indexed image of data type double or single , then imwrite converts the indices to zero-based indices by subtracting 1 from each element, and then writes the data as uint8. You can specify fmt after the input arguments in any of the previous syntaxes.

Alternatively, call the saveas function and specify an. Previously, saved figures were 8-by-6 inches by default. This table lists some common file extensions. Example: "Location",[10,15] Data Types: double. If the output file format does not support bit data, then imwrite returns an error. The row and column dimensions of the Alpha matrix must be the same as those of the image data array. Then write the image data to a PNG file using the new colormap.

Editada: Nini el 21 de Sept. These files contain high quality content that is scalable to any size. I have a double matrix. If image data A is uint8 or logical , then the colormap index is zero-based. Typically, saveas uses the Painters renderer when generating vector graphics files. Tile height and width, specified as a two-element vector. Full path to file, returned as a character vector. Indexed image Integer in the range [1, P ], where P is the colormap length. The value corresponding to these user-specified names must be a string scalar or character vector that contains no control characters other than linefeeds. Starting in Ra, you can use the exportgraphics function to save the contents of any axes, figure, chart that can be a child of a figure, tiled chart layout, or container such as a panel.
