This section allows you to show either the (IPTC) title, (IPTC) caption, name, (Exif) date, folder, and location, or any combination thereof. Text_justify: "L" # text justification L, C or R Show_text: "title caption name date folder location" # default="title caption name date folder location", show text, include combination of words: title, caption name, date, location, folder Show_text_sz: 40 # default=40, text character size Show_text_tm: 20.0 # default=20.0, time to show text over image with file name Name of parameters show_text_fm: "%b %d, %Y" # default "%b %d, %Y", format to show date over the image This defines which Pi3D shader file to use for the transitions. Name of parameter shader: "~/picframe_data/data/shaders/blend_new" and you are seeing weird characters displayed on the screen, changing the font file may be the solution. If you are using a language other than English that has a number of special characters like umlaute, accents, etc. This is the font that is used to display the file names if you have activated this option. Name of parameter font_file: "~/picframe_data/data/fonts/NotoSans-Regular.ttf" This will give you wonderful crossfading transitions. Have a go and see which transition you like best. You have the choice between blend, burn, and bump. Name of parameter blend_type: "blend" # default="blend", choices=, type of blend the shader can do If you have photos in completely different aspect ratios on your frame, then this setting can be very nice. With images, it is typically only the edges, and setting this value to “True” will create a smooth blur. As the video playback is always in landscape mode, two-thirds of the screen is filled with a blurred version of the video. You have surely seen this effect when watching videos that have been filmed in portrait mode on smartphones. This feature will create blurred edges to fill the screen that would otherwise remain black. Name of parameter blur_edges: False # default=False, use blurred version of image to fill edges - will override FIT = False A larger value than 1 will zoom the blur effect. Just leave this value at “1.0”, it will expand the background to just fill the space around the image just right. It expands the background to just fill the space around the image. Name of parameter blur_zoom: 1.0 # default=1.0, must be >= 1.0 which expands the background to just fill the space around the image A value of 1 will make it only slightly blurred, 12 will make it unrecognizable but often yields nice colors. This sets the blur amount to the effect described in the next parameter. Name of parameter blur_amount: 12 # default=12, larger values than 12 will increase processing load quite a bit The order is based on the occurance within the configuration.yaml script. The file has four sections: viewer, model, mqtt, and http. I have mentioned where this is possible and what channel and payload to send. Some of these parameters can be altered with MQTT messages remotely. This is why I have put together a complete overview of all parameters. It is easy to be confused by the many possible options. The information for the various parameters is contained in the configuration.yaml file in the picframe_data/config directory. PictureFrame is highly configurable to your needs. Tested with: Raspberry Pi OS March 2021 version, Raspberry Pi 2, 3, and 4, Pi3D 2.44, PictureFrame 2021.04.02, 1080p and 4K displays.
