Pixia – Phần mềm chỉnh sửa ảnh miễn phí

Pixia is a powerful graphics editor with a unique user interface. When learning Pixia, it’s easier to discard everything you know about Photoshop or Paintshop, and start from scratch with the tutorials and help files.

Basic Specifications
* Pixia is a painting tool made exclusively for full color graphics.
* Maximum graphic size: 10240 x 10240 dots (Note: this depends on RAM capacity.)
* Number of Layers: As many as memory lasts.
* Peripheral devices applicable: TWAIN32 devices. Printers made to use for Microsoft Windows. Tablets (Wacom, Oce-Japan)

How-to (Only things seemingly hard to figure out)
* Right-clicking on the canvas captures the color. Shift + Right-dragging captures the image of the dragged area.
* Freehand drawing with Shift key down draws only the first stroke.
* Selection: After selection, right-clicking on the selected area pops up the sub-menu.
* Palette: Left-click chooses colors. Right-click registers colors. Single colors or bitmaps can be registered and used. There are two kinds of gradations: rectangular and straightline.
* On straightline gradation palette, draggin from the “>” button toward the right adds a color, and dragging a color pointer toward the “>” button erases the color.
* Left-clicking on figures in palettes adds and right-clicking substracts. You can alter figures by directly dragging the pointing lines in palettes. Right-clicking draws the lines toward the mouse pointer.
* Left-dragging with CTRL key down moves the top layer among the ones where the mouse pointer lies. Left-dragging with CTRL and SHIFT keys down moves the current layer.
* Pasting as a new layer is influenced by the settings of Tone Filter and Transparency control.
* Filling with a color also gets influenced by Tone Filter.
* Layers: A layer consists of three planes: Image, Mask, and Transparency. Copy a layer into the clipboard and all the three planes are copied. Paste is also done affected by transparency and selection of the original image. When you paste onto the Mask Plane, or Transparency Plane, only the contrast information is pasted. Pasted on a new layer, all the three planes are maintained exactly as the original layer.
* Registering bitmaps to the palette makes duplicates of the original images in the “palette” folder, which means registering many big size images to the palette will result in consuming a lot of hard disk space.
* Help files do not come with this program. You need to download a separate file from the Pixia website.
