From: [EMAIL PROTECTED] Operating system: Linux x86 PHP version: 4.0 Latest CVS (15/04/2001) PHP Bug Type: PDF related Bug description: pdf_setcolor optional parameters not optional In pdf_setcolor() which is part of pdflib-4.0 and in the CVS of PHP, pdf_setcolor() can take a number of paramters depending on the type of color space you choose. This can be either rgb, gray, pattern, spotcolor or cmyk. Depending on what colorspace you choose, the paramters c1, c2, c3 and c4 are either optional or compulsory. For example, if you choose a colorspace of 'rgb' then you only need to specify c1, c2 and c3. A colorspace of 'cmyk' requires all four and a colorspace of 'gray', 'spotcolor' or 'pattern' merely requires one. Currently though, you must specify all 4 values with the non-used ones being ignored. If you do not specify the ignored paramters then the function terminates the script with an error. For example pdf_setcolor($pdf, "stroke", "rgb", 0.5, 0.5, 0.5); should be correct because you only need to specify the reg, green and blue components. In reality the function must be used as pdf_setcolor($pdf, "stroke", "rgb", 0.5, 0.5, 0.5, 0.0); with the fourth paramter being ignored. The problem is more pronounced when you specify a pattern or gray color pdf_setcolor($pdf, "fill", "pattern", $pattern); is what it would logically be, but the function requires pdf_setcolor($pdf, "fill", "pattern", $pattern, 0.0, 0.0, 0.0); which IMHO is just confusing and makes the function harder to understand in the long run. Can the function be changed to make the optional paramters truly optional? A simple switch/case statement in the function for the colorspace should suffice. -- Edit Bug report at: http://bugs.php.net/?id=10436&edit=1 -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
