Fala Marcelo, no arquivo Archetypes/Field.py você encontra o seguinte: class ImageField(FileField): """ implements an image attribute. it stores it's data in an image sub-object
sizes is an dictionary containing the sizes to scale the image to. PIL is required for that. Format: sizes={'mini': (50,50), 'normal' : (100,100), ... } syntax: {'name': (width,height), ... } the scaled versions can then be accessed as object/<imagename>_<scalename> e.g. object/image_mini where <imagename> is the fieldname and <scalename> is the name from the dictionary original_size -- this parameter gives the size in (w,h) to which the original image will be scaled. If it's None, then no scaling will take place. This is important if you don't want to store megabytes of imagedata if you only need a max. of 100x100 ;-) max_size -- similar to max_size but if it's given then the image is checked to be no bigger than any of the given values of width or height. example: ImageField('image', original_size=(600,600), sizes={ 'mini' : (80,80), 'normal' : (200,200), 'big' : (300,300), 'maxi' : (500,500)}) will create an attribute called "image" with the sizes mini, normal, big, maxi as given and a original sized image of max 600x600. This will be accessible as object/image and the sizes as object/image_mini object/image_normal object/image_big object/image_maxi the official API to get tag (in a pagetemplate) is obj.getField('image').tag(obj, scale='mini') ... sizes may be the name of a method in the instance or a callable which returns a dict. Don't remove scales once they exist! Instead of removing a scale from the list of sizes you should set the size to (0,0). Thus removeScales method is able to find the scales to delete the data. Scaling will only be available if PIL is installed! If 'DELETE_IMAGE' will be given as value, then all the images will be deleted (None is understood as no-op) """ Ou seja, se seu campo se chama image e sua escala banner, basta chamar contexto_objeto/image_banner e você tem a imagem redimensionada. A única exigência aqui é a PIL, naturalmente. Revisa suas definições e se der problema, mande detalhes ;) Abraços. 2009/7/11 Marcello Bontempo Salgueiro <mbsalgue...@linuxmail.org> > > > Salve a todos! > > Galera estou com uma pequena duvida, fiz um produdo de portifolio que > tem duas classes, uma chamada Portifolio e outra Imagem e na classe > imagem eu tenho um atributo do tipo image e coloquei um valuetag sizes > com o valor {'ver':(500,400),'thumb':(58,58)} só que > montei minha pagetemplate assim: > > $objeto/getURL/Imagem_ver > > ele não redimensiona a imagem para 500,400 alguem pode da uma forca!? > > []s > > Marcello. > > > -- -- Rodrigo Castardo Liberiun COO rodrigocasta...@liberiun.com +55 61 9123-7847 +55 61 3468-2662
