General Problems

When I tried to save after attempting to quit with an unsaved file the file became corrupted

This has been fixed in version 0.5.5b. Please upgrade as this is a serious bug.

I get a ClassCastException when exporting an image containing a text-path to SVG

This has been fixed in version 0.5.5b.

The parshape and shapepar functions aren't available when there's more than one object in the image

This has been fixed in version 0.5.4b.

The response is very slow

The response time has improved with version 0.5b, however the following things can still slow Jpgfdraw's reaction time: setting the anti-aliasing on; setting the rendering to quality instead of speed; using a dash pattern with a zero length gap (use a solid line instead).

In addition, if you don't have much memory available: high magnifications, displaying the grid and having a high number of subdivisions on the grid may also slow response time.

Top

When I try moving narrow objects, I end up accidentally scaling/rotating/shearing them

Disable the hotspots using the Settings->Configure... dialog box.

Top

Sometimes lines don't show up

If you have a thin line, and the magnification is small or you have low resolution, the line may be too thin to show up on your display. Try either using a thicker line style, or increasing the magnification.

Top

I lose the cursor when creating a text area at magnifications other than 100%

This has been fixed in version 0.1.6b.

Top

When I try clicking on the canvas to add a new point, nothing happens

Make sure that you are actually clicking and not dragging. Some touch sensitive mouse pads can mistake a click for a drag. Also make sure that you are using one of the construction tools, not the selection tool.

Top

I tried changing the line/text style but nothing happened

Remember to use the Edit->Path and Edit->Text sub-menus to change the styles for existing objects, and use Settings->Styles for all subsequent new objects.

Top

I can't select my text areas (text areas have zero area bounding boxes)

This was fixed in version 0.1.4b.

Top

When I drag to select several objects, sometimes the objects within the drag rectangle are not selected

This was fixed in version 0.1.4b.

Top

The dialog boxes reset themselves when they lose the focus

This was fixed in version 0.1.4b.

Top

The dialog boxes don't have the correct initial values

This was fixed in version 0.1.7b.

Top

Some of the arrow heads come out dashed instead of solid

This was fixed in version 0.1.7b.

Top

Arrow heads point sideways, but they should be pointing another way (e.g., upwards)

Check to make sure you don't have multiple control points at the end of the path. (Select the path, go to edit path mode, and try moving the end point to see if there is a point below it.) If this happens, Jpgfdraw tries to fit an arrow head to a segment with zero dimensions, so it can't work out the correct orientation. Deleting the extra point should fix the problem.

This problem is likely to happen if you have a sensitive touch pad, as it can interpret a double click as a click (new control point) followed by a double-click (new control point and finish path.) If this is the case, it is better to use a single click to set the last point, and then use the Enter key to complete the path.

Also, check the auto-orientation marker settings.

Top

The "End Marker" and "All Markers" dialog boxes have the wrong titles

This has been fixed in version 0.4.1b.

When I undo starting a new text area, I go back to select mode, but the edit text area is still there

This was fixed in version 0.1.7b.

Null pointer exceptions

  1. I get a null pointer exception when starting up using Vista and JRE6:
    javax.swing.text.JTextComponent.getText(Unknown Source)
    uk.ac.uea.cmp.nlct.jdrresources.numfield.DoubleField.isValid(DoubleField.java:56)
    
    This only seems to happen with Vista and JRE6, apparently it doesn't happen with JRE5. I will try to find out how to get it to work with the latest version of Java, but for now Vista users will have to stick to an older version of Java.

  2. I get a null pointer exception when starting up using OS X:
    Exception in thread "main" java.lang.NullPointerException
             at JDRFrame.getFont(JpgfDraw.java:681)
    
    This bug should be fixed in version 0.1.9b.

  3. I get a null pointer exception when starting up:
    JpgfDraw.getString(JpgfDraw.java: 15768)
    JpgfDraw.error(JpgfDraw.java: 15556)
    JpgfDraw.main(JpgfDraw.java: 17620)
    
    This bug should be fixed in version 0.2.1b

  4. I get a null pointer exception when exporting to flowframe (sty) file.

    This bug should be fixed in version 0.5.4b.

Top

I get an exception when pasting an object (using version 0.3b)

This has been fixed in version 0.31b.

Top

Exception in thread "Image Fetcher 0" java.lang.OutOfMemoryError

This can happen if you insert several large bitmaps (e.g. photos) in your image. You can allocate more memory as follows:

  1. Load the jpgfdraw script into a text editor (or jpgfdraw.bat if you are using Windows.) This is located in the bin subdirectory of Jpgfdraw's installation directory.
  2. Add the option -Xmx512m to the java command. (If you require more or less than 512M change this amount as appropriate.)
  3. Reload Jpgfdraw.

The pointer doesn't move when I used the Go To Co-ordinates dialog box

If you are using a version prior to version 0.33b, it's possible the java.awt.Robot wasn't initialised. Load the configuration settings file (jpgfdraw.conf) into a text editor, and replace robot=0 with robot=1. Note also that some systems don't allow applications to move the pointer.

Top

The canvas doesn't always scroll to the correct location when using the some of the navigation functions

This should be fixed in version 0.33b.

Top

I changed the screen mode whilst Jpgfdraw was running, and 1in on the canvas no longer displays as 1in on the screen

The mapping between bp and screen pixels is computed on startup to improve Jpgfdraw's reaction time, so it doesn't register the change in screen mode. The Bitmap->Refresh menu item will update the scaling factor.

Top

Objects are not restored to their original location when undoing alignment

This has been fixed in version 0.5b.

Top

Edit text field doesn't register F3 key

This has been fixed in version 0.5b.

Top

Sometimes doesn't register that the file has been saved when closing an image

This has been fixed in version 0.5b.

Top

Text field used to create a new text area doesn't regain focus after dismissing the symbol dialog box

This has been fixed in version 0.5b.

Top

Title bar information doesn't get updated when closing a child window while another one is still open

This has been fixed in version 0.5b.

Top

Title bar information doesn't get updated when switching child windows

This has been fixed in version 0.5b.

Top

Composite markers are not included in the bounding box

This has been fixed in version 0.5b.

Top

Sometimes text gets drawn outside paper limits

This has been fixed in version 0.5b.

Top

If line paint is transparent and markers set to colour as path, the marker dialog box gives error message

This has been fixed in version 0.5b.

Top

Text area bounding boxes are sometimes incorrect

This has been fixed in version 0.5b.

Top

Flowframe and bitmap annotations aren't taken into account when redrawing

This has been fixed in version 0.5b.

Top

Using the delete key to delete a control point causes whole path to disappear

This has been fixed in version 0.5b.

Top

Dash dialog box has the secondary dash disabled even though the secondary button is checked

This has been fixed in version 0.5b.

Top

Undo sometimes replaces second object with duplicate of first object

This has been fixed in version 0.5b.

Top

Break path function doesn't clone markers

This has been fixed in version 0.5b.

Top

Scaling/rotating/shearing a group containing subgroups doesn't transform subgroups correctly

This has been fixed in version 0.5b.

Top

Printer settings not remember in same session

This has been fixed in version 0.5b.

Top

Discarding image while editing path doesn't cancel edit mode

This has been fixed in version 0.5b.

Printing landscape image containing text results in missing/misplaced text when using java version 1.6.0

I think this is caused by the Java bug identified in http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6487767

Version 0.5.1b of Jpgfdraw has a workaround that should prevent this from occurring. If you are using an older version of Jpgfdraw, you will either need to update to Jpgfdraw version 0.5.1b or use an older version (1.5.0) of Java.

Top


If I transform a text area, the text is no longer displayed correctly when using Java version 1.6.0

This is caused by the same problem as the previous bug. This problem shouldn't occur with version 0.5.1b of Jpgfdraw.

Top

Edit font size and edit font styles dialog boxes always assume 10pt normal font size

This has been fixed in version 0.5.2b.

Top

Parshape and shapepar functions are always shaded when there is more than one object in the image

This has been fixed in version 0.5.4b.
