I have 255 jpeg imaged, and i want to load these according to a varibale.

for(i=0;i>255;i++){loadImage("%.jpeg",i)

Cant i do something like that? To load 1.jpg 2.jpg 3.jpg etc.

Also how can i preload these images? And call them later when i need.

Thanks!

Hi!

I'm new to processing and im trying to code a simple drawing thingy. But its color picker is working very slow.

Here's the code;
1. int k=0,pre_k=0,pickx,picky,picka;
2. boolean k_kontrol=true;
3. int ch=0,cs=0,cb=0; // secili olan renk
4. int kalinlik=10;
5. void setup(){
6. smooth();
7. colorMode(HSB,250);
8. size(900,600);
9. strokeWeight(2);
10. line(300,0,300,600);
11. ciz_renkpick(255+10,5,25,250);
12. }
13. void draw(){
14. ciz_renkkare(5,5,250);
15. renkpick_kontrol(255+10,5,25,250);
16. renksec(5,5,250);
17. ciz();
18. //gecici
19. noStroke();
20. fill(ch,cs,cb);
21. ellipse(600,300,100,100);
22. //gecici
23. }
24. void ciz_renkkare(int cizx,int cizy,int a){
25. colorMode(HSB,a);
26. if(pre_k!=k){
27. k_kontrol=true;
28. }
30. if(k_kontrol==true){
31. for(int i=1;i<a;i++){
32. for(int j=1;j<a;j++){
33. stroke(k,i,a-j);
34. point(i+cizx,j+cizy);
35. k_kontrol=false;
36. pre_k=k;
37. }
38. }
39. }
40. }
41. void ciz_renkpick(int cizx,int cizy,int a,int b){
42. colorMode(HSB,b);
43. for(int i=1;i<a;i++){
44. for(int j=1;j<b;j++){
45. stroke(j,b,b);
46. point(i+cizx,j+cizy);
47. }
48. }
49. }
50. void renkpick_kontrol(int cizx,int cizy,int a,int b){
51. if(mousePressed==true && cizx+a>mouseX && mouseX>cizx && cizy+b>mouseY && mouseY>cizy){
52. k=mouseY-cizy;
53. }
54. }
55. void renksec(int cizx,int cizy,int a){
56. int i,j;
57. if(mousePressed==true && cizx+a>mouseX && mouseX>cizx && cizy+a>mouseY && mouseY>cizy){
58. i=mouseX-cizx;
59. j=mouseY-cizy;
60. ch=k;
61. cs=i;
62. cb=a-j;
63. }
64. }
65. void ciz(){
66. if(mousePressed==true && 900>pmouseX && pmouseX>300 && 600>pmouseY && pmouseY>0
67. && 900>mouseX && mouseX>300 && 600>mouseY && mouseY>0){
68. fill(ch,cs,cb);
69. stroke(ch,cs,cb);
70. strokeWeight(kalinlik);
71. line(pmouseX,pmouseY,mouseX,mouseY);
72. }
73. }
It was super-slow before i changed it a little bit. Now the square doesnt update unless the "k" variable has changed. Still its updating very slow. Can you help me out?
Also im turkish so some of the stuff is written in turkish. Here's some of the meaning of the words;

kalinlik=thickness

ciz=draw/render

kare=square

kontrol=control

renk=color

gecici=temporary

secili olan renk=current color

Thanks a lot in advance!
