Hi Guys,

I have a need here and would like your help. In a project I'm working, I need to insert a line chart in an Excel file, created through the "Spreadsheet Excel Writer". The problem is that the pChart only generates images in PNG format, and "Spreadsheet Excel Writer" only supports BMP.

I am being forced to do the conversion from PNG to BMP using another script, but I think it would be very interesting through pChart can choose the image format generated by it.

I hope that my username and my topic this time are not excluded.

Hi,

I'm sorry for having removed your thread, this forum is actively spamed by some nice guys and looking at yout nickname I tough it was another robot-driven awesome post. Please accept my appologies.

I've choosen the PNG format because I strongly believe that it's the only one that will have a real future in the www. Anyway, any formats natively supported by the GD library (PNG, JPEG, GIF) can be outputed by this library modifying a bit the render() function of the pImage.class.php file.

Unfortunately, from what I know GD does not support BMP output.

Kind regards,
JD.

Bmp2GD? http://www.phpclasses.org/package/5916-PHP-Convert-images-in-the-BMP-format.html

mice32, thats not what i need. This script convert bmp file to the gd supported file types. I need to do the inverse, transform a PNG image to a BMP image.

This Class solved my problem.

Just render the image with the pChart and invoked the method for format conversion. It worked perfectly when imported the image with the "Spreadsheet Excel Writer".

I leave it as a suggestion to include this class or its derivation to a future version of pChart.

Thanks Guys.
