## Appendix H. Error messages

This list have all error messages that can be thrown by the library. In addition to the English locale there is also a German translation (See Section 6.2.1). Most error messages takes one (or several argument that gives additional specific information and the placeholder in the error messages shows where this additional information should be placed.

For more general information on error handling we refer to Chapter 6

## H.1. Core error messages

The following tables lists all error messages that can be generated by standard core graphs types

<table border="1"><tr><td style="color:darkred; font-size:1.2em;"><b>JpGraph Error:</b> HTTP headers have already been sent.<br>Caused by output from file <b>%s</b> at line <b>%d</b>.</td></tr><tr><td><b>Explanation:</b><br>HTTP headers have already been sent back to the browser indicating the data as text before the library got a chance to send it's image HTTP header to this browser. This makes it impossible for the library to send back image data to the browser (since that would be interpretated as text by the browser and show up as junk text).<p>Most likely you have some text in your script before the call to <i>Graph::Stroke()</i>. If this texts gets sent back to the browser the browser will assume that all data is plain text. Look for any text, even spaces and newlines, that might have been sent back to the browser. <p>For example it is a common mistake to leave a blank line before the opening "<b>&lt;?php</b>".</td></tr></table>

`25042` | Unknown background image layout
`25043` | Unknown title background style.
`25044` | Cannot use auto scaling since it is impossible to determine a valid min/max value of the Y-axis (only null values).

`25065` | Tick positions must be specified as an array()
`25066` | When manually specifying tick positions and labels the number of labels must be the same as the number of specified ticks.
`25067` | Your manually specified scale and ticks is not correct. The scale seems to be too small to hold any of the specified tick marks.
`25068` | A plot has an illegal scale. This could for example be that you are trying to use text auto scaling to draw a line plot with only one point or that the plot area is too small. It could also be that no input data value is numeric (perhaps only '-' or 'x')
`25069` | Grace must be larger then 0
`25070` | Either X or Y data arrays contains non-numeric values. Check that the data is really specified as numeric data and not as strings. It is an error to specify data for example as '-2345.2' (using quotes).
`25071` | You have specified a min value with SetAutoMin() which is larger than the maximum value used for the scale. This is not possible.
`25072` | You have specified a max value with SetAutoMax() which is smaller than the minimum value used for the scale. This is not possible.
`25073` | Internal error. Integer scale algorithm comparison out of bound (r=%f)
`25074` | Internal error. The scale range is negative (%f) [for %s scale] This problem could potentially be caused by trying to use \"illegal\" values in the input data arrays (like trying to send in strings or only NULL values) which causes the auto scaling to fail.
`25075` | Can't automatically determine ticks since min==max.
`25077` | Adjustment factor for color must be > 0
`25078` | Unknown color: %s
`25079` | Unknown color specification: %s, size=%d

`25085` | An image can not be created from the supplied string. It is either in a format not supported or the string is representing an corrupt image.
`25086` | You only seem to have GD 1.x installed. To enable Alphablending requires GD 2.x or higher. Please install GD or make sure the constant USE_GD2 is specified correctly to reflect your installation. By default it tries to auto detect what version of GD you have installed. On some very rare occasions it may falsely detect GD2 where only GD1 is installed. You must then set USE_GD2 to false.
`25087` | This PHP build has not been configured with TTF support. You need to recompile your PHP installation with FreeType support.
`25088` | You have a misconfigured GD font support. The call to imagefontwidth() fails.
`25089` | You have a misconfigured GD font support. The call to imagefontheight() fails.
`25090` | Unknown direction specified in call to StrokeBoxedText() [%s]
`25091` | Internal font does not support drawing text at arbitrary angle. Use TTF fonts instead.

`25092`

There is either a configuration problem with TrueType or a problem reading font file "%s" Make sure file exists and is in a readable place for the HTTP process. (If 'basedir' restriction is enabled in PHP then the font file must be located in the document root.). It might also be a wrongly installed FreeType library. Try upgrading to at least FreeType 2.1.13 and recompile GD with the correct setup so it can find the new FT library.

`25093` | Can not read font file "%s" in call to Image::GetBBoxTTF. Please make sure that you have set a font before calling this method and that the font is installed in the TTF directory.
`25094` | Direction for text most be given as an angle between 0 and 90.
`25095` | Unknown font font family specification.

`25107` | Can't write to file "%s". Check that the process running PHP has enough permission.
`25108` | Can't stream image. This is most likely due to a faulty PHP/GD setup. Try to recompile PHP and use the built-in GD library that comes with PHP.
`25109` | Your PHP (and GD-lib) installation does not appear to support any known graphic formats. You need to first make sure GD is compiled as a module to PHP. If you also want to use JPEG images you must get the JPEG library. Please see the PHP docs for details.
