Add new colours in palette by modifying direct levels of RGB or CMY scheme One uses this option to create or modify colours in the palette set of themes by directly choosing the three basic colours in additive mode red green blue or subtractive mode cyan magenta yellow The colour can also be recopied in another by using the right button of the mouse Edit colour palette CLLLLLILLLL LIL indes couleur x La Savamer 9 02 OIRD MS User manual 3 3 7 Permute Permute colours in the palette This option makes it possible to permute two colours within the same palette It is initially necessary to click on the colour to permute and then click desired colour Note It is preferable to use this option rather than to create when you want to remain in the same palette without having to seek new colours Colours permutation in a palette DI L Ti en ra en L hh IE en Li Ix Lo Ix EN LT L Li Li qi To select the colour to be permuted then to move towards the color wished by maintaining the cursor of the mouse Savamer 9 02 OIRD MS User manual 3 3 8 Benday Select colours from benday The technique of the benday 1s a manufactoring process of the offset films intended for the offset printing in four primary inks CMJ N At e2. used for the coordinate conversion X Y f j D Forward equation jl f X Y Inverse equation The forward equations are used to transform geographic coordinates latitude J and longitude 1 into Cartesian coordinates X Y while the inverse equations of a map projection are used to transform Cartesian coordinates into geographic coordinates eH 4 pies EJ Latitude fuite i Bes Dar gel Edda o 50 100 150 0 Longitude Savamer module preserves all the data of the objects in geographical co ordinates longitude latitude The geographic projection 1s necessary to display and represent the data on the screen There are different kinds of map projections using the different parts of the world to minimise the distortion The menu projection allows us to choose the projection which we need SAVANE has several types of projections to use which are Geographical Mercator Lambert and UTM These projections cover the whole of the needs for representation with average and great scales Savamer 9 02 OIRD User manual 5 In the case of image data selection of projection 15 important because data are preserved in geographical co ordinates If 1t 15 possible to represent vector data according to the projections UTM or Lambert or Mercator a mosaic of images could be restored only in plan o
