variables<BR> imX,imY = im.size()<BR> rX=float(tfw.readline())<BR> tfw.readline()<BR> tfw.readline()<BR> rY=float(tfw.readline())<BR> mnX=float(tfw.readline())<BR> mnY=float(tfw.readline())<BR> mxX=mnX+imX*rX<BR> mxY=mnY+imY*rY</div> <div> </div> <div> # assign variables to REQUEST<BR> REQUEST.set('resX', rX)<BR> REQUEST.set('resY', rY)<BR> REQUEST.set('minX', mnX)<BR> REQUEST.set('minY', mnY)<BR> REQUEST.set('maxX', mxX)<BR> REQUEST.set('maxY', mxY)<BR> REQUEST.set('pixelX', imX)<BR> REQUEST.set('pixelY', imY)<BR></div> <div>--------------------------------------</div> <div>but all I get is this</div> <div> </div> <div>zope coercing to Unicode:
