      The Texture Pane

      Texture Pane Introduction

      The Texture Pane allows you to create up to five Textures that can be used when painting in Pena. You access the Texture Pane by tapping the Texture Pane icon on the Control Pane:

      This next section outlines the basic functionality of the Texture Pane, or you can view the video tutorial Pena Tutorial #5 - Using the Texture Pane.

      When the Texture Pane opens it will attach either to the top or bottom of the Control Pane, depending on where it can fit better.

      Changing the position of the Control Pane will also change the position of the Texture Pane.

      To close the Texture Pane simply hit the Texture Pane icon on the Control Pane. Opening up most other panes will also close the Texture Pane.

      About Textures and Noise

      Pena has five Texture slots available for painting. Each Texture slot can contain:

      • Photo - A photo from your devices Photo Album.
      • Noise - Generated noise. You select the size, monochrome/color, and weighting factor.
      While each Texture slot can hold both a Photo and Noise, you can only use one at a time (either the Photo, or the Noise) from a single Texture slot.

      When you Save your work, all five Texture slots are saved. If you have 5 photos and 5 noise, all of that is saved with your work. Even if you delete the photo from your Photo Album, they are still preserved with your Pena work.

      The Five Windows

      At the top of the Texture Pane are five square windows, labeled Texture 1 through Texture 5.

      The first time you run Pena, each window will be black because you have no Photos or Noise loaded.

      Below each window are a pair of icons:


      The Left button is the Photo Button, the right is the Noise Button. By default the Photo Button is lit.

      The Window above the icons shows which ever icon is lit. If Photo is lit, the window will show the current photo, if there is one loaded. If Noise is lit, the window will show the current noise pattern, if one is setup.

      You can switch back and forth between Photo and Noise, but you can not use both, in the same window, at the same time.

      So, for example, you might have Texture 1, 2, and 3, set to different Photos and Texture 4 and 5 set to different Noises.

      If you tap the window, what happens is different whether or not you are in Photo or Noise (with a photo and noise loaded):

      • For Noise - tapping the window will cause the noise to be regenerated using a different seed (if allowed by the setup).
      • For Photos - tapping the photo will give you the following Pop Up:

      If you would like to remove the Photo from the Texture Slot, tap Clear Photo, otherwise tap Cancel to do nothing. If you clear the Photo the window will display black when Photo is selected.

      Note that both Photos and Noise will fill the window completely regardless of the dimensions of the Photo or Noise. So images may appear distorted in the window... this is by design.


      Photo Picker

      There are five Photo Picker icons, one for each of the five Textures.

      To load a photo, tap the Photo icon of the Texture slot you wish to add a photo to. If there is already a Photo loaded, tap it a second time.

      After a pause the Photo Picker should appear. Find the desired photo and tap it to load it into the Texture slot.

      There is a limit to the maximum size a texture can be. That limit is 4,000,000 pixels (four million).

      If the image you selected is larger than 4,000,000 pixels you will see this message:

      If you do not want to use that texture, tap Cancel Load. Otherwise tap Resize to fit to have the image resized to the largest it can be and still fit within 4,000,000 pixels. The actual photo in your Photo Album will not be changed. Pena stores textures independently of the Photo Album.

      To clear a photo from a Texture slot, tap the square window for that Texture and confirm the Pop Up message.


      Noise Maker

      There are five Noise Maker icons, one for each for the five Textures.

      To define noise, tap the Noise icon of the Texture slot you wish to define noise for. If there is already Noise loaded, tap it a second time.

      You will see the following Pop Up:

      The Portrait X Size and Portrait Y Size set the number of squares both horizontally (X) and vertically (Y) in portrait mode. Even if you are holding the device in landscape, set those values as if you were holding the device in portrait. You can use the thumb wheel to dial in the value or tap the number to enter it with the keyboard.

      The X and Y size are applied to the entire screen. That means that in portrait orientation, there are 768 pixels in the X and 1024 in the Y. So that is the maximum (densest) noise pattern you can create - each pixel will be a different noise value.

      If you select, for example, an X and Y size of 10 x 10 - you will have 100 squares of random shades or colors, 10 by 10.

      The Monochrome button controls whether or not the noise is color, or shades of grey. When set to a Green Check Mark the noise will be monochrome (not color). When set to a Red X, the noise will be colored.

      The Alpha Noise button specifies whether you want the Alpha channel to be filled with noise as well. When set to a Red X the Alpha channel is not modified. When set to a Green Check Mark, noise is generated in the Alpha channel as well as the other color channels.

      Since the Alpha channel controls the transparency of what you are painting, setting the Alpha channel to noise will cause the transparency of each area to have a different, random value.

      The Minimum and Maximum button set the range that the noise will be generated in. A full range of noise is used if Minimum is zero and Maximum is 255. For monochrome, that will be all values between black and white. For color, it is the complete color spectrum. Change the maximum and minimum to set a narrower range of colors or shades.

      The Random Seed and Current Seed area set the seed for the noise. The number entered in Current Seed will always produce the same noise, as long as the other settings remain unchanged.

      For example, if you like the noise that you see with a seed of 1234, then as long as the rest of the settings are unchanged you should see the same noise.

      The Random Seed check box specifies whether the Current Seed is locked or not.

      When Random Seed is set to a Green Check Mark, tapping the Texture window containing the noise will cause a new seed to be generated and a new noise pattern to be displayed. The new seed value will appear in the Current Seed area. When Random Seed is set to a Red X, tapping the Texture window will not change the seed or the noise pattern. To change the seed in this mode use the Current Seed thumb wheel or enter it with the keyboard.


      Copy To Drawing

      The Copy To Drawing icon lets you load any texture directly to the Canvas. The texture is loaded so that it fills the entire Canvas.

      Once you tap the Copy To Drawing icon you will see this Pop Up:

      Only Textures slots you have something in will be shown. Select the Texture you want loaded to the Canvas or select Cancel to dismiss the Pop Up.


      Copy From Drawing

      The Copy From Drawing icon lets you copy the current Canvas to any of the five Textures. It replaces the Photo, if there is one.

      Once you tap the Copy From Drawing icon you will see this Pop Up:

      Select the Texture slot you want the Canvas copied to, or select Cancel to dismiss the Pop Up.
