When saving in PDF - Acrobat® format, you can select export options in the PDF Options dialog box that appears before the file is saved. (See Exporting as PDF.)
Computer Graphics Metafile (CGM) format is a standard for exchanging 2-D graphics and text.
With Canvas X Draw, you can open, modify, and save CGM files created in other applications. CGM file properties, including WebCGM tags are retained, and can be viewed in the Object Properties palette.
Variations and extensions to the “standard” format can create incompatibilities with the Canvas X Draw file filter. When you save a Canvas X Draw document in CGM format, Canvas X Draw makes the following image color mode conversions:
Canvas X Draw image mode
CGM image mode
CMYK, Duotone, Grayscale, and LAB color
RGB cell arrays
Black & White
CGM versions 1 and 2: RGB cell arrays
CGM versions 3 and 4: Black & White
First channel becomes an RGB cell array; other channels ignored
Select a version. If your original document was Version 4 (WebCGM), be sure to select this version for export so that any imported data is preserved in the exported file.
Select either CALS or ATA.
Select either 16 Bit Integer or 32 Bit Fixed.
Select either Abstract or Metric.
Export Paint Object
If your file contains paint objects, select this option to export them. Deselect this option if you do not want to export the paint objects.
Export Layer As Picture
If selected, each layer is exported as a separate image. If deselected, the file will be exported as one image.
Beziers As Polygons
If objects contain a fill ink, select this option to preserve it. All beziers will export as polygons. If this option is deselected and the objects are exported as beziers, the fill color is removed.
Bitonal Image Compression
This option is enabled if Version 3 or 4 is selected in the CGM Version menu. Select either Not Compressed, Group 3 (1-dimensional), or Group 4 (2-dimensional).
Click this button to open the CGM Font Matching dialog box. Select a substitute font if you want to change the font when exported to CGM format. The font remains the same in the original file.
Canvas X Draw also supports importing CGM and CGM*PIP files. (See Importing CGM Files.)
Defined by AutoCAD, DWG is accepted as the standard file format for data interchange by CAD users worldwide. The AutoCAD DWG import filter lets you import native AutoCAD® 2004 files. into Canvas X Draw. This filter fits an AutoCAD drawing into a specified page format.

Drawing Interchange Format (DXF) is a format developed by Autodesk, Inc., for exchanging data with AutoCAD and other drawing applications. DXF format provides platform-independent storage of 2D and 3D technical drawings and supports multiple layers. Canvas X Draw supports DXF files containing ASCII data, but does not support DXF files that contain data in binary format.
When opening or placing DXF files, the DWG & DXF Import dialog box opens. The DXF filter fits a DXF file to a specified page format. As with, the DWG import, you should know the Source Unit, Paper Format, and Drawing Scale. (See To Open DWG Files:.)
When opening a DXF file, Canvas X Draw makes the following conversions from DXF objects to Canvas X Draw objects:
Canvas X Draw objects
Traces, Solids, and Quadratic polylines
Bézier curve paths
ATTDEF and ATTRIB
Canvas X Draw doesn’t support 3D objects (3D lines and 3D Face objects in DXF files), so these objects are not imported into Canvas X Draw.
When you save a document in DXF format, Canvas X Draw converts the following Canvas X Draw objects and attributes to DXF objects and attributes:
Canvas X Draw objects/attributes
Pen and fill patterns
Solid pens are exported; fills are not exported
Calligraphic pen strokes
Fixed-width pen strokes
Dashes start in each segment
Layer names with spaces or non-uppercase characters
Spaces removed and characters become uppercase
Objects appear in original colors
In the DXF export options dialog box, select the platform format to use. You can also select options for exporting lines and circles.
Encapsulated PostScript (EPS) is a file format used to save individual PostScript graphics.
When you open or place an EPS file, a dialog box prompts you to choose an import method.
Choose an option and click OK.
When you save a Canvas X Draw document in EPS format, you could lose specialized objects and attributes that are not supported in EPS. Canvas X Draw transparency effects are rendered and stored as images in EPS graphics, using the Transparency Rendering option and resolution that you select.
Preview: Select a format to store a preview image in the EPS file. Canvas X Draw and other programs that support EPS previews will display the preview when the EPS file is placed in a document. The image format and color mode you select are applied to the preview image only.
Choose None for no preview, or choose a color mode to save a preview image. Preview images are saved in TIFF format. A preview will not appear in programs that support only WMF or EMF previews.
Color Mode for DCS format: Select a color mode for the separations stored in the EPS file. Select CMYK to separate all colors, including spot colors, as process (CMYK) colors. Select CMYK + Spot to separate all colors, except spot colors, as process (CMYK) colors. Spot colors will not be converted to process and will be separated as spot colors.
When you use DCS Format and print color separations, the program you use simply outputs the color separation plates as defined in the DCS file; it does not apply its separation method or options to colors in the file. Therefore, if you want to be able to output process and spot color plates, you should select CMYK + Spot Color Mode when you use DCS Format to save illustrations in EPS files.
After you import an EPS file, choose options from the context menu to convert the object or view information about it.
You can view linking information if the file was imported as an EPSF reference. If the file was imported as an EPSF object, you can convert it to an EPSF reference. If it was imported as an EPSF object, you can create Canvas X Draw objects from it.
Select the EPS graphic and right-click. In the context menu, choose one of the options described below.
For saving graphics in GIF and JPEG formats (the standard Web image formats), you have the choice of using the integrated dialog box (Web Images) or the individual GIF or JPEG dialog boxes.
You can use a wizard to save graphics for the Web. Select the images you want to save, and choose File | Save to Web.
Exporting allows you to save selected images, but not entire documents. The difference between Save As and Export is that Save As will render objects or an entire document to create an image that can be saved. Export will save only a single paint object, without rendering.
The Export Preview dialog box shows one, two, or four previews of a graphic image when you choose Save As or Export and select GIF or JPEG file format. You can select settings for each preview image to compare how the file format, palette options, and other settings will affect the image you are saving.
A color tile shows the color you point to in a preview image. Two pairs of coordinates are displayed below the preview panes. One pair are the X,Y coordinates of the pointer. The other pair are the coordinates of the pixel at the upper-left corner of the preview panes.
Click a preview button to change the preview setup. You can select one preview, two previews (horizontal or vertical), or four previews.
One preview pane is active and has a highlighted border. Click a pane to make it active. The settings in the dialog box apply to the active preview. The settings in the dialog box can be different for each preview. When you select a preview, Canvas X Draw updates the dialog box to show the settings for the active preview.
All panes show the image at the same view location and zoom level. Drag on a preview image to move the view location.
Use the zoom menu to zoom in or out. Or, click the Magnifying Glass button, then click a preview image to zoom in. To zoom out, Shift-click a preview image.
Without selecting the Magnifying Glass button, you can zoom in or out by clicking in a preview image. Press Ctrl or Ctrl+Shift and click.
Each preview pane shows the original image. To view how the selected file format and other settings will affect the image, select the Show Preview option above a preview pane. Canvas X Draw will apply all the settings in the dialog box to the preview image. If you change a setting, Canvas X Draw will apply the new setting.
Image file information: When Show Preview is selected, the estimated file size and the number of colors in the image appear above the active preview pane. The first value is the estimated file size in kilobytes. The second value is the number of discrete colors that will be saved in a GIF file; the value is not shown for JPEG format.
To use JPEG format, select JPEG from the Format menu. Canvas X Draw applies the JPEG format and settings to the active preview pane.
To use GIF format, select GIF from the Format menu. Canvas X Draw applies the GIF format and settings to the active preview pane.
Use the menu or type in the box to specify the maximum number of colors to be used in the image. Fewer colors can result in a smaller file, but too few colors will degrade an image.
A palette is a set of colors used in an image. To be saved in GIF format, an image can contain no more than 256 colors. If the image contains more colors, the original colors are mapped to the colors in the palette that you choose.
To apply a custom or system color palette to a paint object before saving in GIF format, select the paint object and choose Image | Mode | Indexed. In the dialog box, select a palette option and click OK. To modify an Indexed mode paint object, choose Image | Mode | Color Table.
Select this option to merge single pixels into similar colored areas to produce smaller file sizes. However, in images with fine lines or detail, this option can reduce image quality. This option is less effective when Dither is also selected and an image has a limited number of colors.
Select this option if you want Canvas X Draw to use dithering to simulate a greater range of colors. Dithering can make an image appear to have more colors than are in a limited color palette, but it can also make an image appear grainy or noisy. To control the amount of dithering, enter a percentage from 1 to 100 in the text box.
Select this checkbox to save the image as an interlaced GIF. Interlacing divides the image data for faster initial display in Web browsers that support interlaced GIF images; i.e., the image appears progressively on the Web page.
The Dropper tools in the Export Preview dialog box let you make colors in a GIF image transparent. Click in the color palette or the current preview image to select colors for transparency. When you select a color, it becomes highlighted in the grid.
Use the regular dropper to select one transparent color. If you click another color, it replaces the current transparent color.
Use the add/subtract dropper to select additional colors to be transparent. Each color you click becomes transparent. To restore a transparent color, click it again.
A checkerboard pattern appears in areas of the preview image that are transparent.
Color palette: The area below the GIF options shows the current color palette for the image. The palette changes when you change the Palette or Max Color option.
Save the current options in the Export Preview dialog box and then apply the same setup to other images.
To save the current options in the dialog box, choose Save Setting in the menu above the current preview pane. Type a name for the saved setting and click OK. This setting will be available in the menu above each preview pane.
Select the Show Preview option above a preview pane and then select the saved setting in the menu.
Select the setting in the menu, and then choose Delete Setting. Canvas X Draw will ask you to confirm that you want to delete the setting.
When you open or import a Photoshop file that contains layers, Canvas X Draw imports the file’s layers as separate objects and stacks them in the document on the current layer.
Layers that have transparency are imported with visibility masks. Canvas X Draw creates an alpha channel and a channel mask for a Photoshop layer mask. Canvas X Draw also imports alpha channels.
Tag Image File Format is a high resolution, raster image format. Canvas X Draw supports both RGB and CMYK TIFFs. Although TIFF is a common format, many TIFF variations exist. Different resolutions, color systems, previews, and compression schemes make the format flexible, but can cause compatibility problems.
Canvas X Draw can read tiled TIFFs. A tiled TIFF is an image divided into smaller, rectangular portions.
When you save TIFF files, you have various options in the Export TIFF dialog box.
Various compression options are available, depending on the mode of the image you are saving.
Indicates the default resolution. Enter a value in the Horizontal and Vertical field, if necessary.
Canvas X Draw supports transparency in TIFF images upon import and export. In Canvas X Draw, you can create transparency in images using either a clipping path, channel mask, or visibility mask.
If you are using vector objects, the vector objects will be rendered before exporting.
Scalable Vector Graphics (SVG) is a vector graphics language written in Extensible Markup Language (XML). This format enables two-dimensional images to be displayed in XML pages on the Web. With the SVG format, graphics are coded directly into an XML document.
In contrast to JPEG and GIF images on the Web, which are bitmapped and always remain a specified size, SVG images are scalable to the size of the viewing window and will adjust in size and resolution according to the window in which it is displayed.
You can import or save SVG and SVGZ files.
This dialog box is similar to the HTML Options dialog box. (See HTML Options.)
The HTML options dialog box offers identical choices for image export. (See Image Options.)
Alternatively, you can choose SVGZ as the file format. This will embed all images and export your project as a single file. If you are exporting a multi-page file, you can opt to save each page individually by enabling the Separate pages checkbox from the SVGZ Export Options dialog.
AVI is the abbreviation of Audio Video Interleave, which is the most common format for audio/video data on the Windows system. When opened, an AVI file plays in a similar fashion to an animated GIF file.
Canvas X Draw has the capability of saving certain Canvas X Draw files in AVI format. Canvas X Draw documents that contain frames, animations or presentations, can be saved as Audio Video Interleave. Even a document with a single frame can be saved in AVI format providing a default time for the single frame is set to 1 second.
When working with Animation documents, you set the timing via the Document Layout palette (Setting Options in the Palette). If you are creating a Presentation document, use the Slide Show palette to control timing. (See Slide Show Palette.)
Text is a standard format for files containing only ASCII (American Standard Code for Information Interchange) encoded characters.
Text format is available on nearly every computer platform; it’s the “plain vanilla” format, the lowest common denominator for words and numbers. Text files don’t include proprietary or application-specific character or formatting codes. Some punctuation marks, symbols, and all accented letters are non-ASCII characters that display incorrectly when used in text files. Still, ASCII text can be used to transfer text among a variety of applications, including text editors, word processors, and databases.
When you open a text file, Canvas X Draw creates one text object containing the file’s contents, and assigns the default font and text formatting attributes to it. If the file contains more text than can fit in the Canvas X Draw workspace, Canvas X Draw truncates the text object and displays an overflow indicator. You can then flow the truncated text into other columns.
